Definitions
- the present invention relates to a detergent portion unit with at least one receiving chamber filled with a solid detergent or cleaning agent, which is formed by a water-soluble cover that includes a water-soluble nonwoven fabric. Furthermore, the application relates to a method for producing this detergent portion unit and a washing method for textiles using such a detergent portion unit.
- water-soluble polymers are generally formed into receiving chambers, which are then filled with a detergent or cleaning agent and finally sealed.
- the receiving chambers can be produced, for example, from water-soluble polymer films (foils) by deep-drawing processes.
- a water-soluble polymer is injection molded into a receptacle.
- Both solid and liquid detergents or cleaning agents are suitable for filling the water-soluble containers. If solid detergents or cleaning agents are used and these contain gas-releasing components such as bleach, the closed water-soluble container has perforations to avoid excessive pressure build-up, which enable gas exchange between the interior of the receiving chamber and the environment. The execution of corresponding perforations requires an additional process step in the production of the water-soluble packaging material or in the production of the filled detergent dosing units.
- the filled detergent portion units are generally hygroscopic due to the water-soluble packaging material used to produce them.
- the tendency and ability of the packaging to absorb water can result in portion units adhering to the surfaces of machines or packaging materials and being unable to be optimally conveyed, or in adjacent portion units, for example in a common outer packaging, glue together.
- portion units adhering to the surfaces of machines or packaging materials are unable to be optimally conveyed, or in adjacent portion units, for example in a common outer packaging, glue together.
- the powdering of the water-soluble detergent portion units in turn requires an additional process step.
- the fragrances added to the detergent or cleaning agent only come into their own to a very limited extent or not at all in the case of detergent portion units, in contrast to conventional solid detergent powders.
- detergent products are marketed whose outer cardboard packaging is provided, for example, with fragrance-containing adhesives and gives the consumer a scent impression of the detergent or cleaning agent contained.
- the washing performance provided by the detergent portion unit is directly related to the dissolving properties of the portion unit. Precisely in view of the increasing use of cold washing processes, it is preferable to keep the thickness of the water-soluble film material contained in the detergent portion unit as small as possible in order to accelerate the dissolution process. At the same time, however, the reduction in the thickness of the surrounding film material results in reduced mechanical stability of the portion units. Overcoming this apparent dichotomy of mechanical stability and dissolution rate using water-soluble film-packaged detergent dosage units is still a relevant aspect in the development of water-soluble detergent portion units.
- the application was based on the object of providing water-soluble detergent portion units that can be produced using simplified processes, have high product and storage stability, in a simple manner using the smallest amounts of additional packaging material such as stand-up pouches or cardboard boxes can be assembled and inspire the consumer with an appealing smell, look and feel.
- a detergent portion unit is suitable for solving these tasks, comprising a) solid detergent or cleaning agent b) a water-soluble cover which completely encloses the solid detergent or cleaning agent, the water-soluble cover consisting at least partially of a water-soluble nonwoven fabric.
- the term detergent portion unit describes a form of supply in which a measured portion of a detergent or cleaning agent is present. Detergent portion units therefore denote both forms of supply for textiles and forms of supply for cleaning hard surfaces such as ceramics, glass, metal or tiles.
- the detergent portion unit is preferably in the form of a pouch.
- Their volume is preferably 4 to 70 mL, preferably 6 to 50 mL and in particular 8 to 25 mL.
- the bags can be in the form of sachets (sealed edge bags) or tubular bag packaging.
- this preferably has two water-soluble flat structures which are connected by means of a circumferential sealed seam to form a sachet, the interior of which contains the solid detergent or cleaning agent.
- the two water-soluble fabrics preferably have an identical shape.
- This shape can be basic geometric shapes such as circles, ovals, triangles, squares, rectangles, pentagons, hexagons, heptagons, octagons or other polygons.
- this form can be configured figuratively, for example as an organic form from the plant or animal world.
- At least one of the two water-soluble fabrics of the sachet comprises a water-soluble nonwoven.
- the sealing seams of preferred sachets are exclusively rounded. Surprisingly, it has been shown that during storage and transport, the solid detergent or cleaning agent accumulates in the corners of non-rounded sealing seams, weakening the wrapping material and/or the seam in this area and thus reducing the storage and transport stability of the sachets.
- the detergent portions have a shaped receiving chamber (thermoformed bag).
- the receiving chambers can have any technically feasible shape. Spherical-domed, cylindrical or cubic chambers are particularly preferred. Preferred receiving chambers have at least one edge and one corner, receiving chambers with two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty or more edges or two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty or more corners can also be realized and are preferred according to the invention.
- receiving chambers that can be implemented and are preferred in alternative embodiments of the means according to the invention have a dome-shaped structure.
- the side walls of the receiving chambers are preferably planar. Spatially opposite side walls can be arranged both parallel and non-parallel to one another.
- the base area of the receiving chambers can be convex, concave or planar, with planar base areas being preferred with regard to the later filling of the intermediate space/intermediate spaces located between the receiving chambers.
- the base itself can be designed as a circle, but can also have corners.
- Bases with one corner two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty or more corners are in Within the scope of the present application preferred.
- the transition from the base area to the side wall(s) or the transition between the side walls and one another is designed in a rounded shape. Accordingly, the receiving chambers do not have pointed or sharp edges on the outside, but rather rounded edges.
- the water-soluble nonwoven fabric forms part of the outer surface of the detergent portion unit and is in direct contact with the solid detergent or cleaning agent.
- the detergent portion unit comprises a solid detergent or cleaning agent as the first essential component.
- solids are preferably powders and/or granules and/or extrudates and/or compacts and/or castings, regardless of whether they are pure substances or
- solid detergents or cleaning agents are particularly preferred as solid detergents or cleaning agents.
- the solids mentioned can be present in amorphous and/or crystalline and/or partially crystalline form.
- preferred solids have a water content (determinable, for example, as loss on drying or according to Karl Fischer) below 10% by weight, preferably below 5% by weight.
- Powder is a general term for a form of dividing solid substances and/or mixtures of substances obtained by crushing, i.e. grinding or crushing in a mortar (pulverization), grinding in mills or as a result of atomization or freeze drying.
- a particularly fine division is often called atomization or micronization; the corresponding powders are referred to as micro-powders.
- Preferred powders have a uniform (homogeneous) mixture of the solid, finely divided components and, in the case of mixtures of substances, in particular do not tend to separate into individual components of these mixtures.
- Powders that are particularly preferred in the context of the present application therefore have a particle size distribution in which at least 80% by weight, preferably at least 60% by weight, particularly preferably at least 95% by weight and in particular at least 99% by weight of the powder, in each case based on its total weight, deviate by a maximum of 80%, preferably a maximum of 60% and in particular a maximum of 40% from the average particle size of this powder.
- powders of any particle size can be used, but preferred powders have mean particle sizes of from 40 to 500 ⁇ m, preferably from 60 to 400 ⁇ m and in particular from 100 to 300 ⁇ m. Methods for determining mean particle size usually rely on the aforementioned sieve analysis and are well described in the prior art.
- the powders produced by the process according to the invention therefore contain flow aids or powdering agents, preferably in proportions by weight of 0.1 to 4% by weight, particularly preferably 0.2 to 3% by weight and in particular 0 .3 to 2% by weight, in each case based on the total weight of the powder.
- Preferred flow aids or powders are, preferably in finely ground form, silicates and/or silicon oxide and/or urea.
- powders can be agglomerated by a number of techniques.
- each of the methods known in the prior art for the agglomeration of particulate mixtures is suitable for converting the solids enclosed in the containers produced according to the invention into larger aggregates.
- agglomerates preferably used as solid(s) are, in addition to the granules, the compactates and extrudates.
- Granules are accumulations of granules.
- a granule (granule) is an asymmetric aggregate of powder particles.
- Granulation processes are widely described in the prior art.
- Granules can be produced by wet granulation, by dry granulation or compaction and by melt-solidification granulation.
- wet granulation The most common granulation technique is wet granulation, as this technique has the fewest restrictions and is the safest to produce granules with favorable properties.
- Wet granulation is carried out by moistening the powder mixtures with solvents and/or solvent mixtures and/or binder solutions and/or adhesive solutions and is preferably carried out in mixers, fluidized beds or spray towers, it being possible for said mixers to be equipped with stirring and kneading tools, for example.
- Foams can also be used as granulating agents.
- combinations of fluidized bed(s) and mixer(s) or combinations of different mixers can also be used for the granulation.
- granulation takes place under the influence of low to high shear forces.
- the starting materials used can be, for example, melts (melt solidification) or, preferably aqueous, slurries (spray drying) of solid substances, which are sprayed in at the top of a tower in a defined droplet size, solidify or dry in free fall and Bottom of the tower accumulate as granules.
- Melt solidification is generally particularly suitable for shaping low-melting substances that are stable in the melting temperature range (e.g. urea, ammonium nitrate and various formulations such as enzyme concentrates, pharmaceuticals, etc.), the corresponding granules are also referred to as prills.
- Spray drying is used in particular for the production of detergents or detergent components.
- extruder or perforated roller granulation in which powder mixtures optionally mixed with granulating liquid are plastically deformed during pressing through perforated discs (extrusion) or on perforated rollers.
- the products of extruder granulation are also referred to as extrudates.
- Compacted products can be produced, for example, by dry granulation techniques such as tableting or roller compaction.
- Single or multi-phase tablets or briquettes can be produced by compacting in tablet presses.
- the multi-phase tablets also include, for example, coated tablets and point tablets (bull-eye tablets).
- the briquettes like the flakes produced in the compacting rollers, can be crushed by counter-rotating spiked rollers or passed through sieves after compacting.
- solid substance particles are referred to as cast bodies, which are produced by solidification and/or crystallization from melts or solutions. Solidification and/or crystallization preferably takes place in prefabricated matrices. Depending on the size of the matrix and the intended use of the casting, the castings released from the matrices after solidification can then be used in their original size or, if necessary, after comminution as solids.
- the solid washing or cleaning agent is preferably at least partially colored.
- a colored washing or cleaning agent enables the washing agent portion unit to have an attractive visual design, particularly in combination with a transparent casing.
- the use of colored components in the solid detergent or cleaning agent, in particular in combination with a transparent and/or white envelope, allows simplified detection of insufficiently sealed components Detergent portion units in the area of maturation and packaging downstream of the actual production.
- a second essential component of the detergent portion unit is the water-soluble casing.
- the water-soluble coating consists of at least 50% by weight, preferably at least 60% by weight, particularly preferably 60 to 95% by weight and in particular 65 to 95% by weight of a water-soluble polymer.
- the preferred water-soluble polymer is selected from the group of polyvinyl alcohols and their copolymers, preferably from the group of polyvinyl alcohols.
- the water-soluble cover of the detergent portion unit consists entirely of a water-soluble nonwoven. This embodiment is aesthetically very attractive and technically advantageous, but at the same time involves increased costs.
- the detergent portion unit has a water-soluble cover which comprises a water-soluble polymer film and a water-soluble nonwoven fabric. It is preferred if the water-soluble nonwoven forms at least 10%, preferably 15 to 80%, particularly preferably 25 to 60% and in particular 30 to 45% of the surface area of the detergent portion unit.
- the detergent portion is preferably made up in the form of a bag (sealed-edge bag or thermoformed bag).
- a water-soluble cover which comprises a water-soluble polymer film and a water-soluble nonwoven, the edge areas of the water-soluble polymer film and the water-soluble nonwoven being connected to one another in such a way that both together enclose a volume which is at least partially connected to the solid detergent or cleaning agent is filled.
- the volume enclosed by the water-soluble coating in preferred detergent portion units corresponds to more than twice the volume, preferably more than four times the volume and in particular more than eight times the volume of the water-soluble coating material.
- the proportion by weight of the water-soluble coating in the total weight of the detergent portion unit is less than 20% by weight, preferably less than 10% by weight and in particular less than 8% by weight, particularly preferably between 2 and 10% by weight % and most preferably between 2 and 8% by weight. Due to the stability of the sealing seams obtained in this way, it is preferred if the water-soluble polymer film and the water-soluble nonwoven fabric of the water-soluble cover of the detergent portion unit are connected to one another by heat sealing, water sealing or ultrasonic sealing.
- the water-soluble polymer film and the water-soluble nonwoven fabric of the water-soluble cover of the detergent portion unit are sewn together.
- the resulting seam is not only visually appealing, the sewing of the components of the water-soluble casing also avoids the formation of a difficult-to-dissolve sealing area that occurs when two films or nonwovens or a film and a nonwoven are welded or glued together. For this reason, the execution of such a seam increases the disintegration rate of the detergent portion unit and ensures residue-free dissolution even at low washing temperatures.
- the water-soluble polymer film and the water-soluble nonwoven are sewn together using a water-soluble material, preferably using a water-soluble thread, particularly preferably using a water-soluble thread made of polyvinyl alcohol.
- a group of preferred detergent portion units has at least one receiving chamber.
- Corresponding receiving chambers can be produced, for example, by means of a deep-drawing process, in the course of which a film is drawn into a cavity by the action of a vacuum and shaped into a receiving chamber. This receiving chamber can then be filled and sealed with a water-soluble nonwoven, for example.
- the resulting detergent portion units whose water-soluble cover comprises a thermoformed water-soluble polymer film and a water-soluble nonwoven fabric, are preferred because of their optical and haptic attractiveness, high mechanical stability and easy accessibility.
- Water-soluble polymer films for producing the water-soluble casing are preferably based on a polyvinyl alcohol or a polyvinyl alcohol copolymer.
- the molecular weight of the polyvinyl alcohol or polyvinyl alcohol copolymer is preferably in the range from 10,000 to 1,000,000 gmol -1 , preferably from 20,000 to 500,000 gmol -1 , particularly preferably from 30,000 to 100,000 gmol -1 and in particular from 40,000 to 80,000 gmol -1 .
- the preparation of the polyvinyl alcohol and polyvinyl alcohol copolymers typically involves the hydrolysis of intermediate polyvinyl acetate.
- Preferred polyvinyl alcohols and Polyvinyl alcohol copolymers have a degree of hydrolysis of 70 to 100 mol %, preferably 80 to 90 mol %, particularly preferably 81 to 89 mol % and in particular 82 to 88 mol %.
- preferred polyvinyl alcohol copolymers include an ethylenically unsaturated carboxylic acid, its salt or its ester.
- Such polyvinyl alcohol copolymers particularly preferably contain, in addition to vinyl alcohol, sulfonic acids such as 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), acrylic acid, methacrylic acid, acrylic esters, methacrylic esters or mixtures thereof; among the esters, C 1-4 alkyl esters or - hydroxyalkyl esters are preferred.
- sulfonic acids such as 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), acrylic acid, methacrylic acid, acrylic esters, methacrylic esters or mixtures thereof; among the esters, C 1-4 alkyl esters or - hydroxyalkyl esters are preferred.
- AMPS 2-acrylamido-2-methyl-1-propanesulfonic acid
- Other suitable monomers are ethylenically uns
- Suitable water-soluble films are sold, for example, by MonoSol LLC under the designation M8630, M8720, M8310, C8400 or M8900.
- Other suitable films include films with the designation Solublon® PT, Solublon® GA, Solublon® KC or Solublon® KL from Aicello Chemical Europe GmbH or films VF-HP from Kuraray.
- the water-soluble films can contain additional active substances or fillers, but also plasticizers and/or solvents, in particular water, as further ingredients.
- the group of further active ingredients includes, for example, materials which protect the ingredients of preparation (A) enclosed by the film material from decomposition or deactivation by exposure to light.
- Antioxidants, UV absorbers and fluorescent dyes have proven to be particularly suitable here.
- glycerol ethylene glycol, diethylene glycol, propanediol, 2-methyl-1,3-propanediol, sorbitol or mixtures thereof can be used as plasticizers.

- the group of these active substances includes, for example, the dyes.
- Direct color-based product communication is made possible, for example, by signal colors that draw the consumer's attention to a special product effect.
- Such direct product communication is helpful, for example, in containers that comprise several detergent portion units with different effects, for example detergent portion units for textile cleaning in combination with detergent portion units for textile care, and each of these effects is assigned a specific color.
- An indirectly color-based product combination describes, for example, the product combination by means of an imprint on the water-soluble casing of the detergent portion unit, which is particularly noticeable or easily legible due to the color of the water-soluble casing surrounding the imprint. Varying the base color of the water-soluble casing in this way enables the range of inks available for printing on the water-soluble casing to be expanded.
- preferred water-soluble nonwovens are white, ie not colored.
- the white color of the water-soluble non-woven fabric is particularly suitable for printing.
- Another feature of the nonwoven material that is relevant for printing and how it is perceived is, as already mentioned, its special surface property, which differs from that of a conventional water-soluble film.
- Preferred detergent portion units are consequently characterized in that the water-soluble nonwoven is printed on its outside.

Description
, Waschmittelportionseinheit' 'Detergent serving unit'
Die vorliegende Erfindung betrifft eine Waschmittelportionseinheit mit mindestens einer, mit einem festen Wasch- oder Reinigungsmittel befüllten Aufnahmekammer, welche von einer wasserlöslichen Umhüllung gebildet wird, die einen wasserlöslichen Vliesstoff umfasst. Weiterhin betrifft die Anmeldung ein Verfahren zur Herstellung dieser Waschmittelportionseinheit und Waschverfahren für Textilien unter Einsatz einer solchen Waschmittelportionseinheit. The present invention relates to a detergent portion unit with at least one receiving chamber filled with a solid detergent or cleaning agent, which is formed by a water-soluble cover that includes a water-soluble nonwoven fabric. Furthermore, the application relates to a method for producing this detergent portion unit and a washing method for textiles using such a detergent portion unit.
An die Konfektions- und Angebotsformen von Wasch- und Reinigungsmittel werden sich kontinuierlich ändernde Anforderungen gestellt. Ein Hauptaugenmerk liegt dabei seit geraumer Zeit auf der bequemen Dosierung von Wasch- und Reinigungsmitteln durch den Verbraucher und der Vereinfachung der zur Durchführung eines Wasch- oder Reinigungsverfahren notwendigen Arbeitsschritte. Eine technische Lösung bieten vorportionierte Wasch- oder Reinigungsmittel, beispielsweise wasserlösliche Behälter mit einer oder mehreren Aufnahmekammern für feste oder flüssige Wasch- oder Reinigungsmittel. Constantly changing requirements are placed on the packaging and supply forms of detergents and cleaning agents. For some time now, the main focus has been on the convenient dosing of detergents and cleaning agents by the consumer and the simplification of the work steps required to carry out a washing or cleaning process. A technical solution is provided by pre-portioned detergents or cleaning agents, for example water-soluble containers with one or more receiving chambers for solid or liquid detergents or cleaning agents.
Zur Herstellung der wasserlöslichen Behälter werden in der Regel wasserlösliche Polymere zu Aufnahmekammern verformt, welche nachfolgend mit einem Wasch- oder Reinigungsmittel befüllt und schließlich verschlossen werden. Die Aufnahmekammern können beispielsweise aus wasserlöslichen Polymerfilmen (Folien) durch Tiefziehverfahren hergestellt werden. In einer alternativen Verfahrensführung wird ein wasserlösliches Polymer durch Spritzguss zu einem Aufnahmebehälter verformt. To produce the water-soluble containers, water-soluble polymers are generally formed into receiving chambers, which are then filled with a detergent or cleaning agent and finally sealed. The receiving chambers can be produced, for example, from water-soluble polymer films (foils) by deep-drawing processes. In an alternative process, a water-soluble polymer is injection molded into a receptacle.
Zur Befüllung der wasserlöslichen Behälter eignen sich feste wie flüssige Wasch- oder Reinigungsmittel. Werden feste Wasch- oder Reinigungsmittel eingesetzt und enthalten diese Gasfreisetzende Bestandteile wie Bleichmittel, so weist der verschlossene wasserlösliche Behälter zur Vermeidung einer übergroßen Druckbildung Perforationen auf, welche einen Gasaustausch zwischen dem Inneren der Aufnahmekammer und der Umgebung ermöglichen. Die Ausführung entsprechender Perforationen setzt einen zusätzlichen Verfahrensschritt bei der Herstellung der wasserlöslichen Verpackungsmittel oder bei der Herstellung der befüllten Waschmitteldosiereinheiten voraus. Both solid and liquid detergents or cleaning agents are suitable for filling the water-soluble containers. If solid detergents or cleaning agents are used and these contain gas-releasing components such as bleach, the closed water-soluble container has perforations to avoid excessive pressure build-up, which enable gas exchange between the interior of the receiving chamber and the environment. The execution of corresponding perforations requires an additional process step in the production of the water-soluble packaging material or in the production of the filled detergent dosing units.
Die befüllten Waschmittelportionseinheiten sind aufgrund des zu ihrer Herstellung eingesetzten wasserlöslichen Verpackungsmaterials in der Regel hygroskopisch. Die Wasseraufnahmeneigung und Wasseraufnahmefähigkeit der Verpackungsmittel kann im Rahmen der Herstellung, Verpackung, Lagerung und späteren Nutzung durch den Verbraucher dazu führen, dass Portionseinheiten an Oberflächen von Maschinen oder Verpackungsmitteln haften und nicht optimal gefördert werden können oder einander benachbarte Portionseinheiten, beispielsweise in einer gemeinsamen Umverpackung, miteinander verkleben. Zur Vermeidung dieser Haftungsneigung der wasserlöslichen Portionseinheiten, ist es mögliche, deren
Oberflächeneigenschaften durch Aufbringen eines Pudermittels zu modifizieren. Die Abpuderung der wasserlöslichen Waschmittelportionseinheiten bedingt wiederum einen zusätzlichen Verfahrensschritt. The filled detergent portion units are generally hygroscopic due to the water-soluble packaging material used to produce them. During manufacture, packaging, storage and subsequent use by the consumer, the tendency and ability of the packaging to absorb water can result in portion units adhering to the surfaces of machines or packaging materials and being unable to be optimally conveyed, or in adjacent portion units, for example in a common outer packaging, glue together. To avoid this liability tendency of the water-soluble portion units, it is possible To modify surface properties by applying a powder. The powdering of the water-soluble detergent portion units in turn requires an additional process step.
Schließlich bedingt die chemische Natur üblicher wasserlöslicher Verpackungsmittel, beispielsweise Polymerfolien, in Kombination mit deren latenter Hygroskopizität eine spezifische Produkthaptik, die als klebrig wahrgenommen werden kann und das Produkterlebnis schmälert. Finally, the chemical nature of common water-soluble packaging materials, such as polymer films, in combination with their latent hygroscopicity, results in a specific product feel that can be perceived as sticky and reduces the product experience.
Bedingt durch die Portionierung in einem wasserlöslichen Verpackungsmaterial kommen bei Waschmittelportionseinheiten, anders als bei üblichen festen Waschmittelpulvern, die dem Waschoder Reinigungsmittel zugesetzten Duftstoffe nur sehr begrenzt oder gar nicht zur Geltung. Als eine Reaktion auf diesen Sachverhalt werden Waschmittelprodukte vermarktet, deren äußere Kartonage beispielsweise mit Duftstoff-haltigen Klebemitteln versehen ist und dem Verbraucher einen Dufteindruck des enthaltenen Wasch- oder Reinigungsmittels vermittelt. Due to the portioning in a water-soluble packaging material, the fragrances added to the detergent or cleaning agent only come into their own to a very limited extent or not at all in the case of detergent portion units, in contrast to conventional solid detergent powders. As a reaction to this situation, detergent products are marketed whose outer cardboard packaging is provided, for example, with fragrance-containing adhesives and gives the consumer a scent impression of the detergent or cleaning agent contained.
Schließlich steht die durch die Waschmittelportionseinheit erbrachte Waschleistung in direktem Zusammenhang mit den Auflösungseigenschaften der Portionseinheit. Gerade im Hinblick auf den zunehmenden Einsatz von Kaltwaschverfahren ist es bevorzugt, die Dicke des in der Waschmittelportionseinheit enthaltenen wasserlöslichen Filmmaterials möglichst gering zu halten, um den Auflösungsprozess zu beschleunigen. Die Verringerung der Dicke des umgebenden Filmmaterials bedingt jedoch gleichzeitig eine verminderte mechanische Stabilität der Portionseinheiten. Die Überwindung dieser scheinbaren Dichotomie von mechanischer Stabilität und Auflösungsgeschwindigkeit mittels wasserlöslicher Folien verpackter Waschmitteldosiereinheiten ist nach wie vor ein relevanter Gesichtspunkt bei der Entwicklung wasserlöslicher Waschmittelportionseinheiten. Finally, the washing performance provided by the detergent portion unit is directly related to the dissolving properties of the portion unit. Precisely in view of the increasing use of cold washing processes, it is preferable to keep the thickness of the water-soluble film material contained in the detergent portion unit as small as possible in order to accelerate the dissolution process. At the same time, however, the reduction in the thickness of the surrounding film material results in reduced mechanical stability of the portion units. Overcoming this apparent dichotomy of mechanical stability and dissolution rate using water-soluble film-packaged detergent dosage units is still a relevant aspect in the development of water-soluble detergent portion units.
Vor dem Hintergrund des zuvor beschriebenen Standes der Technik lag der Anmeldung die Aufgabe zugrunde, wasserlösliche Waschmittelportionseinheiten bereitzustellen, die mittels vereinfachter Verfahren herstellbar sind, über eine hohe Produkt- und Lagerstabilität verfügen, in einfacher Weise unter Einsatz geringster Mengen an zusätzlichem Verpackungsmaterial wie Standbodenbeuteln oder Kartonagen konfektionierbar sind und den Verbraucher durch eine ansprechende Olfaktorik, Optik und Haptik begeistern. Against the background of the prior art described above, the application was based on the object of providing water-soluble detergent portion units that can be produced using simplified processes, have high product and storage stability, in a simple manner using the smallest amounts of additional packaging material such as stand-up pouches or cardboard boxes can be assembled and inspire the consumer with an appealing smell, look and feel.
Zur Lösung dieser Aufgaben eignet sich eine Waschmittelportionseinheit, umfassend a) festes Wasch- oder Reinigungsmittel b) eine wasserlösliche Umhüllung, welche das feste Wasch- oder Reinigungsmittel vollständig umschließt, wobei die wasserlösliche Umhüllung wenigstens anteilsweise aus einem wasserlöslichen Vliesstoff besteht.
Die Bezeichnung Waschmittelportionseinheit beschreibt eine Angebotsform, in welcher eine abgemessene Portion eines Wasch- oder Reinigungsmittels vorliegt. Waschmittelportionseinheiten bezeichnen folglich sowohl Angebotsformen für Textilien als auch Angebotsformen für die Reinigung harter Oberflächen wie Keramik, Glas, Metall oder Fliesen. A detergent portion unit is suitable for solving these tasks, comprising a) solid detergent or cleaning agent b) a water-soluble cover which completely encloses the solid detergent or cleaning agent, the water-soluble cover consisting at least partially of a water-soluble nonwoven fabric. The term detergent portion unit describes a form of supply in which a measured portion of a detergent or cleaning agent is present. Detergent portion units therefore denote both forms of supply for textiles and forms of supply for cleaning hard surfaces such as ceramics, glass, metal or tiles.
Die Waschmittelportionseinheit liegt vorzugsweise in Form eines Beutels vor. Ihr Volumen beträgt bevorzugt 4 bis 70 mL, vorzugsweise 6 bis 50mL und insbesondere 8 bis 25 mL. The detergent portion unit is preferably in the form of a pouch. Their volume is preferably 4 to 70 mL, preferably 6 to 50 mL and in particular 8 to 25 mL.
Die Beutel können in Form von Sachets (Siegelrandbeuteln) oder Schlauchbeutelverpackungen vorliegen. Im Falle der Konfektionierung als Sachet weist dieses vorzugsweise zwei wasserlösliche Flächengebilden auf, welche mittels einer umlaufenden Siegelnaht zu einem Beutel verbunden sind, dessen Inneres das feste Wasch- oder Reinigungsmittel enthält. Die beiden wasserlöslichen Flächengebilde weisen vorzugsweise eine identische Form auf. Bei dieser Form kann es sich um geometrische Grundformen wie Kreise, Ovale, Dreiecke, Quadrate, Rechtecke, Fünfecke, Sechsecke, Siebenecke, Achtecke oder weitere Vielecke handeln. Alternativ kann diese Form figürlich ausgestaltet sein, beispielsweise als organische Form aus der Pflanzen- oder Tierwelt. Bevorzugt umfasst mindestens eines der beiden wasserlöslichen Flächengebilde des Sachets einen wasserlöslichen Vliesstoff. Die Siegelnähte bevorzugter Sachets weisen ausschließlich abgerundete Verläufe auf. Überraschenderweise hat es sich gezeigt, dass bei Lagerung und Transport das feste Wasch- oder Reinigungsmittel in den Ecken nicht abgerundeter Siegelnahtverläufe akkumuliert, auf diese Weise das Umhüllungsmaterial und/oder die Naht in diesem Bereich schwächt und so die Lager- und Transportstabilität der Sachets mindert. The bags can be in the form of sachets (sealed edge bags) or tubular bag packaging. In the case of packaging as a sachet, this preferably has two water-soluble flat structures which are connected by means of a circumferential sealed seam to form a sachet, the interior of which contains the solid detergent or cleaning agent. The two water-soluble fabrics preferably have an identical shape. This shape can be basic geometric shapes such as circles, ovals, triangles, squares, rectangles, pentagons, hexagons, heptagons, octagons or other polygons. Alternatively, this form can be configured figuratively, for example as an organic form from the plant or animal world. Preferably, at least one of the two water-soluble fabrics of the sachet comprises a water-soluble nonwoven. The sealing seams of preferred sachets are exclusively rounded. Surprisingly, it has been shown that during storage and transport, the solid detergent or cleaning agent accumulates in the corners of non-rounded sealing seams, weakening the wrapping material and/or the seam in this area and thus reducing the storage and transport stability of the sachets.
In einer alternativen Ausführungsform weisen die Waschmittelportionen eine ausgeformte Aufnahmekammer (Tiefziehbeutel) auf. Die Aufnahmekammern können jede technisch realisierbare Form aufweisen. Sphärisch-kuppelförmig, zylindrische oder kubische Kammern sind besonders bevorzugt. Bevorzugte Aufnahmekammern weisen mindestens eine Kante und eine Ecke auf, Aufnahmekammern mit zwei, drei, vier, fünf, sechs, sieben, acht neun, zehn, elf, zwölf, dreizehn, vierzehn, fünfzehn, sechszehn, siebzehn, achtzehn, neunzehn, zwanzig oder mehr Kanten bzw. zwei, drei, vier, fünf, sechs, sieben, acht neun, zehn, elf, zwölf, dreizehn, vierzehn, fünfzehn, sechszehn, siebzehn, achtzehn, neunzehn, zwanzig oder mehr Ecken sind ebenfalls realisierbar und erfindungsgemäß bevorzugt. Weitere realisierbare und in alternativen Ausführungsformen der erfindungsgemäßen Mittel bevorzugte Aufnahmekammern weisen einen kuppelförmigen Aufbau auf. Die Seitenwände der Aufnahmekammern sind vorzugsweise planar. Räumlich gegenüberliegende Seitenwände können sowohl parallel als auch nicht parallel zueinander angeordnet sein. Die Grundfläche der Aufnahmekammern kann konvex, konkav oder planar sein, wobei mit Rücksicht auf die spätere Befüllung des/der zwischen den Aufnahmekammern befindlichen Zwischenraums/Zwischenräume planare Grundflächen bevorzugt sind. Die Grundfläche selbst kann als Kreis ausgestaltet, kann aber auch Ecken aufweisen.
Grundflächen mit einer Ecke (Tropfenform), zwei, drei, vier, fünf, sechs, sieben, acht, neun, zehn, elf, zwölf, dreizehn, vierzehn, fünfzehn, sechszehn, siebzehn, achtzehn, neunzehn, zwanzig oder mehr Ecken sind im Rahmen der vorliegenden Anmeldung bevorzugt. Der Übergang der Grundfläche zu der oder den Seitenwänden bzw. der Übergang der Seitenwände ineinander wird in bevorzugten Ausführungsformen dieser Anmeldung in abgerundeter Form ausgestaltet. Die Aufnahmekammern weisen demnach nach außen keine spitzen oder scharfen sondern vielmehr abgerundete Kanten auf. In an alternative embodiment, the detergent portions have a shaped receiving chamber (thermoformed bag). The receiving chambers can have any technically feasible shape. Spherical-domed, cylindrical or cubic chambers are particularly preferred. Preferred receiving chambers have at least one edge and one corner, receiving chambers with two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty or more edges or two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty or more corners can also be realized and are preferred according to the invention. Other receiving chambers that can be implemented and are preferred in alternative embodiments of the means according to the invention have a dome-shaped structure. The side walls of the receiving chambers are preferably planar. Spatially opposite side walls can be arranged both parallel and non-parallel to one another. The base area of the receiving chambers can be convex, concave or planar, with planar base areas being preferred with regard to the later filling of the intermediate space/intermediate spaces located between the receiving chambers. The base itself can be designed as a circle, but can also have corners. Bases with one corner (teardrop shape), two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty or more corners are in Within the scope of the present application preferred. In preferred embodiments of this application, the transition from the base area to the side wall(s) or the transition between the side walls and one another is designed in a rounded shape. Accordingly, the receiving chambers do not have pointed or sharp edges on the outside, but rather rounded edges.
In einer bevorzugten Ausführungsform der Waschmittelportionseinheit bildet der wasserlösliche Vliesstoff einen Teil der Außenfläche der Waschmittelportionseinheit und steht in direktem Kontakt zu dem festen Wasch- oder Reinigungsmittel. In a preferred embodiment of the detergent portion unit, the water-soluble nonwoven fabric forms part of the outer surface of the detergent portion unit and is in direct contact with the solid detergent or cleaning agent.
Die Waschmittelportionseinheit umfasst als ersten wesentlichen Bestandteil ein festes Wasch- oder Reinigungsmittel. Als Feststoffe gelten im Rahmen der vorliegenden Anmeldung vorzugsweise Pulver und/oder Granulate und/oder Extrudate und/oder Kompaktate und/oder Gießkörper und zwar unabhängig davon, ob es sich um Reinsubstanzen oder umThe detergent portion unit comprises a solid detergent or cleaning agent as the first essential component. In the context of the present application, solids are preferably powders and/or granules and/or extrudates and/or compacts and/or castings, regardless of whether they are pure substances or
Substanzgemische handelt. Als feste Wasch- oder Reinigungsmittel werden Granulate, Extrudate und Kompaktate besonders bevorzugt. Die genannten Feststoffe können dabei in amorpher und/oder kristalliner und/oder teilkristalliner Form vorliegen. Bevorzugte Feststoffe weisen im Rahmen der vorliegenden Erfindung einen Wassergehalt (beispielsweise bestimmbar als Trocknungsverlust oder nach Karl Fischer) unterhalb von 10 Gew.-%, vorzugsweise unterhalb von 5 Gew.-% auf. mixtures of substances. Granules, extrudates and compacts are particularly preferred as solid detergents or cleaning agents. The solids mentioned can be present in amorphous and/or crystalline and/or partially crystalline form. In the context of the present invention, preferred solids have a water content (determinable, for example, as loss on drying or according to Karl Fischer) below 10% by weight, preferably below 5% by weight.
Pulver ist eine allgemeine Bezeichnung für eine Form der Zerteilung fester Stoffe und/oder Stoffgemische, die man durch Zerkleinern, das heißt Zerreiben oder Zerstoßen in der Reibschale (Pulverisieren), Mahlen in Mühlen oder als Folge von Zerstäubungs- oder Gefriertrocknungen erhält. Powder is a general term for a form of dividing solid substances and/or mixtures of substances obtained by crushing, i.e. grinding or crushing in a mortar (pulverization), grinding in mills or as a result of atomization or freeze drying.
Eine besonders feine Zerteilung nennt man oft Atomisierung oder Mikronisierung; die entsprechenden Pulver werden als Mikro-Pulver bezeichnet. Bevorzugte Pulver weisen eine gleichmäßige (homogene) Mischungen der festen feinzerteilten Bestandteile auf und neigen im Falle von Stoffgemischen insbesondere nicht zur Auftrennung in Einzelbestandteile dieser Gemische. Im Rahmen der vorliegenden Anmeldung besonders bevorzugte Pulver weisen daher eine Teilchengrößenverteilung auf, in der mindestens 80 Gew.-%, vorzugsweise mindestens 60 Gew.-%, besonders bevorzugt mindestens 95 Gew.-% und insbesondere mindestens 99 Gew.-% des Pulvers, jeweils bezogen auf dessen Gesamtgewicht, zu maximal 80 %, vorzugsweise maximal 60 % und insbesondere maximal 40 % von der mittleren Teilchengröße dieses Pulvers abweichen.
Nach der Korngröße ist eine grobe Einteilung der Pulver in Grob-, Fein- u. Feinst-Pulver üblich; eine genauere Klassifizierung pulverförmiger Schüttgüter erfolgt über ihre Schüttdichte und durch Siebanalyse. Grundsätzlich lassen sich Pulver jeglicher Partikelgröße einsetzen, bevorzugte Pulver weisen jedoch mittlere Partikelgrößen von 40 bis 500 pm, vorzugsweise von 60 bis 400 pm und insbesondere von 100 bis 300 pm auf. Methoden zur Bestimmung der mittleren Teilchengröße stützen sich gewöhnlich auf die vorgenannte Siebanalyse und sind im Stand der Technik ausführlich beschrieben. A particularly fine division is often called atomization or micronization; the corresponding powders are referred to as micro-powders. Preferred powders have a uniform (homogeneous) mixture of the solid, finely divided components and, in the case of mixtures of substances, in particular do not tend to separate into individual components of these mixtures. Powders that are particularly preferred in the context of the present application therefore have a particle size distribution in which at least 80% by weight, preferably at least 60% by weight, particularly preferably at least 95% by weight and in particular at least 99% by weight of the powder, in each case based on its total weight, deviate by a maximum of 80%, preferably a maximum of 60% and in particular a maximum of 40% from the average particle size of this powder. According to the grain size, a rough classification of the powder into coarse, fine and ultra-fine powder is usual; a more precise classification of powdery bulk materials is based on their bulk density and sieve analysis. In principle, powders of any particle size can be used, but preferred powders have mean particle sizes of from 40 to 500 μm, preferably from 60 to 400 μm and in particular from 100 to 300 μm. Methods for determining mean particle size usually rely on the aforementioned sieve analysis and are well described in the prior art.
Dem unerwünschten Zusammenbacken der Pulver kann man durch Verwendung von Rieselhilfen bzw. Pudermitteln begegnen. In einer bevorzugten Ausführungsform enthalten die in den nach dem erfindungsgemäßen Verfahren hergestellten Pulver daher Rieselhilfen bzw. Pudermittel, vorzugsweise in Gewichtsanteilen von 0,1 bis 4 Gew.-%, besonders bevorzugt von 0,2 bis 3 Gew.- % und insbesondere von 0,3 bis 2 Gew.-%, jeweils bezogen auf das Gesamtgewicht des Pulvers. Bevorzugte Rieselhilfen bzw. Pudermittel sind, vorzugsweise in fein vermahlener Form, Silikate und/oder Siliciumoxid und/oder Harnstoff. The undesirable caking of the powder can be counteracted by using flow aids or powders. In a preferred embodiment, the powders produced by the process according to the invention therefore contain flow aids or powdering agents, preferably in proportions by weight of 0.1 to 4% by weight, particularly preferably 0.2 to 3% by weight and in particular 0 .3 to 2% by weight, in each case based on the total weight of the powder. Preferred flow aids or powders are, preferably in finely ground form, silicates and/or silicon oxide and/or urea.
Als partikuläre Gemische lassen sich Pulver durch eine Reihe von Techniken agglomerieren. Jede der im Stand der Technik zur Agglomeration von partikulären Gemischen bekannte Methode ist dabei prinzipiell geeignet, die in den erfindungsgemäß hergestellten Behältern umschlossenen Feststoffe in größere Aggregate zu überführen. Im Rahmen der vorliegenden Erfindung bevorzugt als Feststoff(e) eingesetzte Agglomerate sind neben den Granulaten die Kompaktate und Extrudate. As particulate mixtures, powders can be agglomerated by a number of techniques. In principle, each of the methods known in the prior art for the agglomeration of particulate mixtures is suitable for converting the solids enclosed in the containers produced according to the invention into larger aggregates. In the context of the present invention, agglomerates preferably used as solid(s) are, in addition to the granules, the compactates and extrudates.
Als Granulate werden Anhäufungen von Granulatkörnchen bezeichnet. Ein Granulatkorn (Granalie) ist ein asymmetrisches Aggregat aus Pulverpartikeln. Granulationsverfahren sind im Stand der Technik breit beschrieben. Granulate können durch Feuchtgranulierung, durch Trockengranulierung bzw. Kompaktierung und durch Schmelzerstarrungsgranulierung hergestellt werden. Granules are accumulations of granules. A granule (granule) is an asymmetric aggregate of powder particles. Granulation processes are widely described in the prior art. Granules can be produced by wet granulation, by dry granulation or compaction and by melt-solidification granulation.
Die gebräuchlichste Granuliertechnik ist die Feuchtgranulierung, da diese Technik den wenigsten Einschränkungen unterworfen ist und am sichersten zu Granulaten mit günstigen Eigenschaften führt. Die Feuchtgranulierung erfolgt durch Befeuchtung der Pulvermischungen mit Lösungsmitteln und/oder Lösungsmittelgemischen und/oder Lösungen von Bindemitteln und/oder Lösungen von Klebstoffen und wird vorzugsweise in Mischern, Wirbelbetten oder Sprühtürmen durchgeführt, wobei besagte Mischer beispielsweise mit Rühr- und Knetwerkzeugen ausgestattet sein können. Als Granulationsmittel können auch Schäume eingesetzt werden. Für die Granulation sind jedoch auch Kombinationen von Wirbelbett(en) und Mischer(n), bzw. Kombinationen verschiedener Mischer einsetzbar. Die Granulation erfolgt abhängig vom Ausgangsmaterial sowie den gewünschten Produkteigenschaften unter Einwirkung niedriger bis hoher Scherkräfte.
Erfolgt die Granulation in einem Sprühturm so können als Ausgangsstoffe beispielsweise Schmelzen (Schmelzerstarrung) oder, vorzugsweise wässrige, Aufschlämmungen (Sprühtrocknung) fester Substanzen eingesetzt werden, welche an der Spitze eines Turmes in definierter Tröpfchengröße eingesprüht werden, im freien Fall erstarren bzw. trocknen und am Boden des Turmes als Granulat anfallen. Die Schmelzerstarrung eignet sich im Allgemeinen besonders zur Formgebung niedrigschmelzender Stoffe, die im Bereich der Schmelztemperatur stabil sind (z. B. Harnstoff, Ammoniumnitrat u. diverse Formulierungen wie Enzymkonzentrate, Arzneimittel etc.), die entsprechenden Granulate werden auch als Prills bezeichnet. Die Sprühtrocknung wird besonders für die Herstellung von Waschmitteln oder Waschmittelbestandteilen eingesetzt. The most common granulation technique is wet granulation, as this technique has the fewest restrictions and is the safest to produce granules with favorable properties. Wet granulation is carried out by moistening the powder mixtures with solvents and/or solvent mixtures and/or binder solutions and/or adhesive solutions and is preferably carried out in mixers, fluidized beds or spray towers, it being possible for said mixers to be equipped with stirring and kneading tools, for example. Foams can also be used as granulating agents. However, combinations of fluidized bed(s) and mixer(s) or combinations of different mixers can also be used for the granulation. Depending on the starting material and the desired product properties, granulation takes place under the influence of low to high shear forces. If the granulation takes place in a spray tower, the starting materials used can be, for example, melts (melt solidification) or, preferably aqueous, slurries (spray drying) of solid substances, which are sprayed in at the top of a tower in a defined droplet size, solidify or dry in free fall and Bottom of the tower accumulate as granules. Melt solidification is generally particularly suitable for shaping low-melting substances that are stable in the melting temperature range (e.g. urea, ammonium nitrate and various formulations such as enzyme concentrates, pharmaceuticals, etc.), the corresponding granules are also referred to as prills. Spray drying is used in particular for the production of detergents or detergent components.
Weitere Agglomerationstechniken sind die Extruder- oder Lochwalzengranulierungen, bei denen optional mit Granulierflüssigkeit versetzte Pulvergemische beim Verpressen durch Lochscheiben (Extrusion) oder auf Lochwalzen plastisch verformt werden. Die Produkte der Extrudergranulierung werden auch als Extrudate bezeichnet. Other agglomeration techniques are extruder or perforated roller granulation, in which powder mixtures optionally mixed with granulating liquid are plastically deformed during pressing through perforated discs (extrusion) or on perforated rollers. The products of extruder granulation are also referred to as extrudates.
Kompaktate lassen sich beispielsweise durch Trockengranulationstechniken wie die Tablettierung oder Walzenkompaktierung herstellen. Durch die Kompaktierung in Tablettenpressen können ein- oder mehrphasige Tabletten oder Briketts hergestellt werden. Zu den mehrphasigen Tabletten zählen neben den Mehrschicht- oder Sandwichtabletten beispielsweise auch die Manteltabletten und die Punkttabletten (Bull-eye-Tabletten). Die Briketts können ebenso wie die in Kompaktierwalzen erzeugten Schülpen im Anschluß an die Kompaktierung durch gegenläufige Stachelwalzen zerkleinert oder durch Siebe geschlagen werden. Compacted products can be produced, for example, by dry granulation techniques such as tableting or roller compaction. Single or multi-phase tablets or briquettes can be produced by compacting in tablet presses. In addition to multi-layer or sandwich tablets, the multi-phase tablets also include, for example, coated tablets and point tablets (bull-eye tablets). The briquettes, like the flakes produced in the compacting rollers, can be crushed by counter-rotating spiked rollers or passed through sieves after compacting.
Als Gießkörper werden im Rahmen der vorliegenden Anmeldung feste Substanzpartikel bezeichnet, welche durch Erstarrung und/oder Kristallisation aus Schmelzen oder Lösungen hergestellt werden. Die Erstarrung und/oder Kristallisation erfolgt bevorzugt in vorgefertigten Matrizen. Die nach Erstarrung aus den Matrizen gelösten Gießkörper können im Anschluss je nach Größe der Matrize und Verwendungszweck des Gießkörpers in ihrer ursprünglichen Größe oder gegebenenfalls nach Zerkleinerung als Feststoffe eingesetzt werden. In the context of the present application, solid substance particles are referred to as cast bodies, which are produced by solidification and/or crystallization from melts or solutions. Solidification and/or crystallization preferably takes place in prefabricated matrices. Depending on the size of the matrix and the intended use of the casting, the castings released from the matrices after solidification can then be used in their original size or, if necessary, after comminution as solids.
Das feste Wasch- oder Reinigungsmittel ist vorzugsweise wenigstens anteilsweise farbig. Ein farbiges Wasch- oder Reinigungsmittel ermöglicht insbesondere in Kombination mit einer transparenten Umhüllung eine ansprechende optische Ausgestaltung der Waschmittelportionseinheit. Darüber hinaus erlaubt die Einsatz von farbigen Bestandteilen in dem festen Wasch- oder Reinigungsmittel insbesondere in Kombination mit einer transparenten und/oder weißen Umhüllung eine vereinfachte Detektion von unzureichend verschlossenen
Waschmittelportionseinheiten im Bereich der der eigentlichen Herstellung nachgeordneten Reifung und Verpackung. The solid washing or cleaning agent is preferably at least partially colored. A colored washing or cleaning agent enables the washing agent portion unit to have an attractive visual design, particularly in combination with a transparent casing. In addition, the use of colored components in the solid detergent or cleaning agent, in particular in combination with a transparent and/or white envelope, allows simplified detection of insufficiently sealed components Detergent portion units in the area of maturation and packaging downstream of the actual production.
Ein zweiter wesentlicher Bestandteil der Waschmittelportionseinheit ist die wasserlösliche Umhüllung. Bei bevorzugten Waschmittelportionseinheit besteht die wasserlösliche Umhüllung zu mindestens 50 Gew.-%, vorzugsweise zu mindestens 60 Gew.-%, besonders bevorzugt zu 60 bis 95 Gew.-% und insbesondere zu 65 bis 95 Gew.-% aus einem wasserlöslichen Polymer. Bevorzugtes wasserlöslichen Polymer ist ausgewählt aus der Gruppe der Polyvinylalkohole und deren Copolymere, vorzugsweise aus der Gruppe der Polyvinylalkohole. A second essential component of the detergent portion unit is the water-soluble casing. In preferred detergent portion units, the water-soluble coating consists of at least 50% by weight, preferably at least 60% by weight, particularly preferably 60 to 95% by weight and in particular 65 to 95% by weight of a water-soluble polymer. The preferred water-soluble polymer is selected from the group of polyvinyl alcohols and their copolymers, preferably from the group of polyvinyl alcohols.
In einer ersten Ausführungsform besteht die wasserlösliche Umhüllung der Waschmittelportionseinheit vollständig aus einem wasserlöslichen Vliesstoff. Diese Ausführungsform ist ästhetisch sehr reizvoll und technisch vorteilhaft, gleichzeitig jedoch mit erhöhten Kosten verbunden. In a first embodiment, the water-soluble cover of the detergent portion unit consists entirely of a water-soluble nonwoven. This embodiment is aesthetically very attractive and technically advantageous, but at the same time involves increased costs.
In einer technisch und wirtschaftlich besonders vorteilhaften bevorzugten Ausführungsform weist die Waschmittelportionseinheit eine wasserlösliche Umhüllung auf, welche einen wasserlöslichen Polymerfilm und einen wasserlöslichen Vliesstoff umfasst. Bevorzugt ist es, wenn der wasserlösliche Vliesstoff mindestens 10%, vorzugsweise 15 bis 80%, besonders bevorzugt 25 bis 60% und insbesondere 30 bis 45% der Oberfläche der Waschmittelportionseinheit bildet. In a preferred embodiment that is technically and economically particularly advantageous, the detergent portion unit has a water-soluble cover which comprises a water-soluble polymer film and a water-soluble nonwoven fabric. It is preferred if the water-soluble nonwoven forms at least 10%, preferably 15 to 80%, particularly preferably 25 to 60% and in particular 30 to 45% of the surface area of the detergent portion unit.
Wie eingangs ausgeführt, ist die Waschmittelportion vorzugsweise in Form eines Beutels (Siegelrandbeutel oder Tiefziehbeutel) konfektioniert. Diese und andere Konfektionsformen lassen sich beispielsweise durch eine wasserlösliche Umhüllung realisieren, welche einen wasserlöslichen Polymerfilm und einen wasserlöslichen Vliesstoff umfasst, wobei die Randbereiche des wasserlöslichen Polymerfilms und des wasserlöslichen Vliesstoffs derart miteinander verbunden sind, dass beide gemeinsam ein Volumen umschließen, welches wenigstens anteilsweise mit dem festen Wasch- oder Reinigungsmittel befüllt ist. As stated at the outset, the detergent portion is preferably made up in the form of a bag (sealed-edge bag or thermoformed bag). These and other ready-made forms can be realized, for example, by a water-soluble cover, which comprises a water-soluble polymer film and a water-soluble nonwoven, the edge areas of the water-soluble polymer film and the water-soluble nonwoven being connected to one another in such a way that both together enclose a volume which is at least partially connected to the solid detergent or cleaning agent is filled.
Um eine effektive Nutzung des eingesetzten Hüllmaterials zu gewährleisten, entspricht bei bevorzugten Waschmittelportionseinheiten das von der wasserlöslichen Umhüllung umschlossene Volumen mehr als dem doppelten Volumen, vorzugsweise mehr als dem vierfachen Volumen und insbesondere mehr als dem achtfachen Volumen des wasserlöslichen Hüllmaterials. In order to ensure effective use of the coating material used, the volume enclosed by the water-soluble coating in preferred detergent portion units corresponds to more than twice the volume, preferably more than four times the volume and in particular more than eight times the volume of the water-soluble coating material.
Aus dem gleichen Grund beträgt bei bevorzugten Waschmittelportionseinheiten der Gewichtsanteil der wasserlöslichen Umhüllung am Gesamtgewicht der Waschmittelportionseinheit weniger als 20 Gew.-%, vorzugsweise weniger als 10 Gew.-% und insbesondere weniger als 8 Gew.-%, besonders bevorzugt zwischen 2 und 10 Gew.-% und ganz besonders bevorzugt zwischen 2 und 8 Gew.-%.
Aufgrund der Stabilität der so erhaltenen Siegelnähte ist es bevorzugt, wenn der wasserlösliche Polymerfilm und der wasserlösliche Vliesstoff der wasserlöslichen Umhüllung der Waschmittelportionseinheit durch Heißsiegeln, Wassersiegeln, Ultraschallsiegeln miteinander verbunden sind. For the same reason, in preferred detergent portion units, the proportion by weight of the water-soluble coating in the total weight of the detergent portion unit is less than 20% by weight, preferably less than 10% by weight and in particular less than 8% by weight, particularly preferably between 2 and 10% by weight % and most preferably between 2 and 8% by weight. Due to the stability of the sealing seams obtained in this way, it is preferred if the water-soluble polymer film and the water-soluble nonwoven fabric of the water-soluble cover of the detergent portion unit are connected to one another by heat sealing, water sealing or ultrasonic sealing.
In einer besonders bevorzugten alternativen Ausführungsform sind der wasserlösliche Polymerfilm und der wasserlösliche Vliesstoff der wasserlöslichen Umhüllung der Waschmittelportionseinheit miteinander vernäht. Die resultierende Naht ist nicht nur optisch reizvoll, durch das Vernähten der Bestandteile der wasserlöslichen Umhüllung wird darüber hinaus die Bildung eines schwerlöslichen Siegelbereichs vermieden, der entsteht, wenn zwei Folien oder Vliese oder eine Folie und ein Vlies miteinander verschweißt oder verklebt werden. Die Ausführung einer solchen Naht erhöht aus diesem Grund die Zerfallsgeschwindigkeit der Waschmittelportionseinheit und stellt eine rückstandsfreie Auflösung auch bei niedrigen Waschtemperaturen sicher. In a particularly preferred alternative embodiment, the water-soluble polymer film and the water-soluble nonwoven fabric of the water-soluble cover of the detergent portion unit are sewn together. The resulting seam is not only visually appealing, the sewing of the components of the water-soluble casing also avoids the formation of a difficult-to-dissolve sealing area that occurs when two films or nonwovens or a film and a nonwoven are welded or glued together. For this reason, the execution of such a seam increases the disintegration rate of the detergent portion unit and ensures residue-free dissolution even at low washing temperatures.
Für die Auflösungseigenschaften der Waschmittelportionseinheit hat es sich als besonders vorteilhaft erwiesen, wenn der wasserlösliche Polymerfilm und der wasserlösliche Vliesstoff mittels eines wasserlöslichen Materials, vorzugsweise mittels eines wasserlöslichen Fadens, besonders bevorzugt mittels eines wasserlöslichen Fadens aus Polyvinylalkohol miteinander vernäht sind. For the dissolving properties of the detergent portion unit, it has proven to be particularly advantageous if the water-soluble polymer film and the water-soluble nonwoven are sewn together using a water-soluble material, preferably using a water-soluble thread, particularly preferably using a water-soluble thread made of polyvinyl alcohol.
Wie zuvor beschrieben, weist eine Gruppe bevorzugter Waschmittelportionseinheiten mindestens eine Aufnahmekammer auf. Entsprechende Aufnahmekammer lassen sich beispielsweise mittels eines Tiefziehverfahrens herstellen, in deren Verlauf eine Folie durch Einwirkung von Unterdrück in eine Kavität gezogen und zu einer Aufnahmekammer ausgeformt wird. Diese Aufnahmekammer kann nachfolgend befüllt und beispielsweise mit einem wasserlöslichen Vliesstoff verschlossen werden. Die resultierenden Waschmittelportionseinheiten, deren wasserlösliche Umhüllung einen tiefgezogenen wasserlöslichen Polymerfilm und einen wasserlöslichen Vliesstoff umfasst, sind aufgrund ihrer optischen und haptischen Attraktivität, hohen mechanischen Stabilität und einfachen Zugänglichkeit bevorzugt. As described above, a group of preferred detergent portion units has at least one receiving chamber. Corresponding receiving chambers can be produced, for example, by means of a deep-drawing process, in the course of which a film is drawn into a cavity by the action of a vacuum and shaped into a receiving chamber. This receiving chamber can then be filled and sealed with a water-soluble nonwoven, for example. The resulting detergent portion units, whose water-soluble cover comprises a thermoformed water-soluble polymer film and a water-soluble nonwoven fabric, are preferred because of their optical and haptic attractiveness, high mechanical stability and easy accessibility.
Wasserlösliche Polymerfilme zur Herstellung der wasserlöslichen Umhüllung basieren bevorzugt auf einem Polyvinylalkohol oder einem Polyvinylalkoholcopolymer. Das Molekulargewicht des Polyvinylalkohols oder Polyvinylalkoholcopolymers liegt vorzugsweise im Bereich von 10.000 bis 1.000.000 gmol’1, bevorzugt von 20.000 bis 500.000 gmol-1, besonders bevorzugt von 30.000 bis 100.000 gmol-1 und insbesondere von 40.000 bis 80.000 gmol-1. Water-soluble polymer films for producing the water-soluble casing are preferably based on a polyvinyl alcohol or a polyvinyl alcohol copolymer. The molecular weight of the polyvinyl alcohol or polyvinyl alcohol copolymer is preferably in the range from 10,000 to 1,000,000 gmol -1 , preferably from 20,000 to 500,000 gmol -1 , particularly preferably from 30,000 to 100,000 gmol -1 and in particular from 40,000 to 80,000 gmol -1 .
Die Herstellung der Polyvinylalkohol und Polyvinylalkoholcopolymere schließt in der Regel die Hydrolyse intermediären Polyvinylacetats ein. Bevorzugte Polyvinylalkohole und
Polyvinylalkoholcopolymere weisen einen Hydrolysegrad 70 bis 100 Mol-%, vorzugsweise 80 bis 90 Mol-%, besonders bevorzugt 81 bis 89 Mol-% und insbesondere 82 bis 88 Mol-% auf. The preparation of the polyvinyl alcohol and polyvinyl alcohol copolymers typically involves the hydrolysis of intermediate polyvinyl acetate. Preferred polyvinyl alcohols and Polyvinyl alcohol copolymers have a degree of hydrolysis of 70 to 100 mol %, preferably 80 to 90 mol %, particularly preferably 81 to 89 mol % and in particular 82 to 88 mol %.
Bevorzugte Polyvinylalkoholcopolymere umfassen neben Vinylalkohol eine ethylenisch ungesättigte Carbonsäure, deren Salz oder deren Ester. Besonders bevorzugt enthalten solche Polyvinylalkoholcopolymere neben Vinylalkohol Sulfonsäuren wie die 2-Acrylamido-2- methyl-1-propansulfonsäure (AMPS), Acrylsäure, Methacrylsäure, Acrylsäureester, Methacrylsäureester oder Mischungen daraus; unter den Estern sind CwAlkylester oder - Hydroxyalkylester bevorzugt. Als weitere Monomere kommen ethylenisch ungesättigte Dicarbonsäuren, beispielsweise Itaconsäure, Maleinsäure, Fumarsäure und Mischungen daraus in Betracht. In addition to vinyl alcohol, preferred polyvinyl alcohol copolymers include an ethylenically unsaturated carboxylic acid, its salt or its ester. Such polyvinyl alcohol copolymers particularly preferably contain, in addition to vinyl alcohol, sulfonic acids such as 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), acrylic acid, methacrylic acid, acrylic esters, methacrylic esters or mixtures thereof; among the esters, C 1-4 alkyl esters or - hydroxyalkyl esters are preferred. Other suitable monomers are ethylenically unsaturated dicarboxylic acids, for example itaconic acid, maleic acid, fumaric acid and mixtures thereof.
Geeignete wasserlösliche Folien werden beispielsweise von der Firma MonoSol LLC unter der Bezeichnung M8630, M8720, M8310, C8400 oder M8900 vertrieben. Andere geeignete Folien umfassen Folien mit der Bezeichnung Solublon® PT, Solublon® GA, Solublon® KC oder Solublon® KL von der Aicello Chemical Europe GmbH oder die Folien VF-HP von Kuraray. Suitable water-soluble films are sold, for example, by MonoSol LLC under the designation M8630, M8720, M8310, C8400 or M8900. Other suitable films include films with the designation Solublon® PT, Solublon® GA, Solublon® KC or Solublon® KL from Aicello Chemical Europe GmbH or films VF-HP from Kuraray.
Die wasserlöslichen Filme können als weitere Inhaltsstoffe zusätzliche Wirk- oder Füllstoffe aber auch Weichmacher und/oder Lösungsmittel, insbesondere Wasser, enthalten. The water-soluble films can contain additional active substances or fillers, but also plasticizers and/or solvents, in particular water, as further ingredients.
Zur Gruppe der weiteren Wirkstoffe zählen dabei beispielsweise Materialien, welche die von dem Folienmaterial umschlossenen Inhaltsstoffe der Zubereitung (A) vor Zersetzung oder Desaktivierung durch Lichteinstrahlung schützen. Als besonders geeignet haben sich hier Antioxidantien, UV-Absorber und Fluoreszensfarbstoffe erwiesen. The group of further active ingredients includes, for example, materials which protect the ingredients of preparation (A) enclosed by the film material from decomposition or deactivation by exposure to light. Antioxidants, UV absorbers and fluorescent dyes have proven to be particularly suitable here.
Als Weichmacher können beispielsweise Glycerin, Ethylenglycol, Diethylenglycol, Propandiol, 2- Methyl-1 ,3-propandiol, Sorbit oder deren Gemische eingesetzt werden. For example, glycerol, ethylene glycol, diethylene glycol, propanediol, 2-methyl-1,3-propanediol, sorbitol or mixtures thereof can be used as plasticizers.
Zur Verminderung ihrer Reibungskoeffizienten kann die Oberfläche des wasserlöslichen Films optional mit feinem Pulver abgepudert werden. Natriumaluminosilicat, Siliciumdioxid, Talk und Amylose sind Beispiele für geeignete Pudermittel. Überraschenderweise wurde festgestellt, dass die Waschmittelportionseinheiten aufgrund des im Bereich der Umhüllung eingesetzten Vliesstoffes einen deutlich verringerten Reibungskoeffizienten und eine deutlich verringerte Verklebungsneigung aufweisen, weshalb der Einsatz von Pudermitteln bei der Herstellung und Lagerung dieser Waschmittelportionseinheiten reduziert oder auf den Einsatz von Pudermitteln sogar vollständig verzichtet werden kann. To reduce their coefficient of friction, the surface of the water-soluble film can optionally be powdered with fine powder. Sodium aluminosilicate, silica, talc and amylose are examples of suitable powdering agents. Surprisingly, it was found that the detergent portion units have a significantly reduced coefficient of friction and a significantly reduced tendency to stick due to the nonwoven fabric used in the area of the cover, which is why the use of powders in the production and storage of these detergent portion units can be reduced or the use of powders can even be completely dispensed with .
Ebenso wie die wasserlöslichen Polymerfilme basieren auch die wasserlöslichen Vliesstoffe vorzugsweise auf einem wasserlöslichen Polymer, und aufgrund ihrer Verfügbarkeit insbesondere
auf Polyvinylalkohol und Polyvinylalkoholcopolymeren, besonders bevorzugt auf Polyvinylalkoholen. Waschmittelportionseinheit nach einem der vorherigen Punkte, wobei der wasserlösliche Vliesstoff zu mindestens 50 Gew.-%, vorzugsweise zu mindestens 70 Gew.-%, besonders bevorzugt zu mindestens 90 Gew.-% und insbesondere zu mindestens 98 Gew.-% aus Polyvinylalkohol oder Polyvinylalkoholcopolymeren, insbesondere aus Polyvinylalkoholen besteht. Like the water-soluble polymer films, the water-soluble non-woven fabrics are preferably based on a water-soluble polymer, and in particular because of their availability on polyvinyl alcohol and polyvinyl alcohol copolymers, particularly preferably on polyvinyl alcohols. Detergent portion unit according to one of the preceding points, wherein the water-soluble nonwoven fabric is at least 50% by weight, preferably at least 70% by weight, particularly preferably at least 90% by weight and in particular at least 98% by weight of polyvinyl alcohol or polyvinyl alcohol copolymers , In particular consists of polyvinyl alcohols.
Neben dem vorzugsweise polymeren wasserlöslichen Grundgerüst können die Vliesstoffe weitere Inhaltsstoffe umfassen. Hierzu zählen beispielswiese Weichmacher, Prozesshilfs mittel oder wasch- und reinigungsaktive Inhaltsstoffe. Bei Zusatz wasch- oder reinigungsaktiver Inhaltsstoffe können diese zwischen die Fasern des Vliesstoffes eingearbeitet sein, wo sie beispielsweise durch Verklebung fixiert werden. Vorzugsweise sind die wasch- oder reinigungsaktiven Inhaltstoffe jedoch integraler Bestandteil der Fasern des Vliesstoffes und sind in die vorzugsweise polymere wasserlösliche Matrix der Fasern eingebettet. In einer bevorzugten Ausführungsform enthält der wasserlösliche Vliesstoff mehr als 2 Gew.-%, vorzugsweise mehr als 4 Gew.-%, besonders bevorzugt mehr als 8 Gew.-%, insbesondere 8 bis 60 Gew.-%, vorzugsweise 12 bis 50 Gew.-% und insbesondere 24 bis 40 Gew.-% wasch- oder reinigungsaktiven Inhaltsstoff. In addition to the preferably polymeric, water-soluble basic structure, the nonwovens can include other ingredients. These include, for example, softeners, processing aids or detergent and cleaning ingredients. If washing or cleaning ingredients are added, they can be incorporated between the fibers of the nonwoven fabric, where they are fixed, for example, by gluing. However, the active washing or cleaning ingredients are preferably an integral part of the fibers of the nonwoven fabric and are embedded in the preferably polymeric, water-soluble matrix of the fibers. In a preferred embodiment, the water-soluble nonwoven contains more than 2% by weight, preferably more than 4% by weight, particularly preferably more than 8% by weight, in particular 8 to 60% by weight, preferably 12 to 50% by weight. -% and in particular 24 to 40% by weight of washing or cleaning-active ingredient.
Besonders geeignet für die Einarbeitung in den Vliesstoff sind wasch- und reinigungsaktive Inhaltsstoffe aus der Gruppe der Tenside, Polymere und Duftstoffe. Die Einarbeitung von Duftstoffen hat eine für den Verbraucher unmittelbar wahrnehmbare Wirkung, weshalb Waschmittelportionseinheiten bevorzugt sind, bei denen der wasserlösliche Vliesstoff mindestens einen wasch- oder reinigungsaktiven Inhaltsstoff aus der Gruppe der Duftstoffe umfasst. Active washing and cleaning ingredients from the group of surfactants, polymers and fragrances are particularly suitable for incorporation into the nonwoven. The incorporation of fragrances has an effect that the consumer can immediately perceive, which is why detergent portion units are preferred in which the water-soluble nonwoven fabric comprises at least one washing or cleaning-active ingredient from the group of fragrances.
Als Vliesstoff werden Gebilde aus Fasern bezeichnet, die zu einer Faserschicht zusammengefügt sind. Im englischen Sprachraum hat sich für Vliesstoffe die Bezeichnung „nonwoven“ etabliert. Die Vliesstoffe sind vorzugsweise flexibel und biegsam. Folien oder Papiere werden nicht zu den Vliesstoffen gezählt. Nonwovens are structures made of fibers that are combined to form a fiber layer. In the English-speaking world, the term “nonwoven” has become established for nonwovens. The nonwovens are preferably flexible and pliable. Foils or papers are not counted as nonwovens.
Bevorzugte Vliese basieren auf wasserlöslichen Polymerfasern, insbesondere auf wasserlöslichen Fasern auf Basis von Polyvinylalkohol und Polyvinylalkoholcopooymeren. Preferred fleeces are based on water-soluble polymer fibers, in particular on water-soluble fibers based on polyvinyl alcohol and polyvinyl alcohol copolymers.
Die Faserlänge der wasserlöslichen Polymerfasern liegt vorzugsweise im Bereich von 1 bis 40 mm, besonders bevorzugt von 2 bis 20 mm. Die Dicke der Fasern beträgt vorzugsweise 0,1 bis 1000 pm, bevorzugt 0,5 bis 400 pm. Die Dichte des Vliesstoffes liegt vorzugsweise oberhalb 0,15 g/cm3, bevorzugt oberhalb 0,2 g/cm3 und insbesondere im Bereich von 0,2 bis 0,8 g/cm3. The fiber length of the water-soluble polymer fibers is preferably in the range from 1 to 40 mm, particularly preferably from 2 to 20 mm. The thickness of the fibers is preferably 0.1 to 1000 μm, preferably 0.5 to 400 μm. The density of the non-woven fabric is preferably above 0.15 g/cm 3 , preferably above 0.2 g/cm 3 and in particular in the range from 0.2 to 0.8 g/cm 3 .
Die Herstellung der Vliesstoffe kann beispielsweise mittels mechanischer, aerodynamischer oder hydrodynamischer Verfahren des Standes der Technik erfolgen. Die Fasern des Vlieses können mechanisch, beispielsweise durch Reib- oder Formschluss, chemisch, beispielsweise durch den
Einsatz von Binde- oder Lösungsmitteln oder thermisch, durch den Einsatz thermoplastischer Zusatzstoffe verfestigt werden. The nonwovens can be produced, for example, by means of mechanical, aerodynamic or hydrodynamic methods of the prior art. The fibers of the web can mechanically, for example by friction or form fit, chemically, for example by the Use of binders or solvents or thermally solidified through the use of thermoplastic additives.
In einer bevorzugten Variante der Waschmittelportionseinheiten handelt es sich bei den wasserlöslichen Vliesstoffen um Nadelvliesstoffe. In entsprechenden Vliesen wird das Verschlingen und damit die Verdichtung und Verfestigung der Fasern durch Vernadeln, beispielsweise mittels geeigneter Nadelbretter oder Nadelbalken erreicht. In a preferred variant of the detergent portion units, the water-soluble nonwovens are needle-punched nonwovens. In corresponding webs, the intertwining and thus the compression and strengthening of the fibers is achieved by needling, for example by means of suitable needle boards or needle bars.
Bevorzugt sind insbesondere solche Vliesstoffe, vorzugsweise Nadelvliesstoffe, aus der Gruppe der Wirrlage Vliesstoffe. Bei diesen Vliesstoffen weisen die Fasern jede beliebige Richtung auf und liegen relativ gleich verteilt in allen Richtungen des Vliesstoffes vor. Entsprechende Vliesstoffe zeichnen sich nicht nur durch eine besondere Optik und Haptik aus, sondern verbessern darüber hinaus aufgrund ihrer Kompressionsfähigkeit die mechanische Stabilität der von der Waschmittelportionseinheit umfassten festen Wasch- oder Reinigungsmittel bei Transport und Lagerung, beispielsweise bei mechanischer Erschütterung eines diese Waschmittelportionseinheit enthaltenen Gebindes. Such nonwovens, preferably needle-punched nonwovens, from the group of randomly oriented nonwovens are particularly preferred. In these nonwovens, the fibers have any direction and are relatively evenly distributed in all directions of the nonwoven. Corresponding nonwovens are not only characterized by a special look and feel, but also improve the mechanical stability of the solid detergents or cleaning agents contained in the detergent portion unit during transport and storage due to their compressibility, for example in the event of mechanical vibration of a container containing this detergent portion unit.
In Bezug auf die optischen, haptischen und mechanischen Eigenschaften der Waschmittelportionseinheit hat es sich als vorteilhaft erweisen, wenn der wasserlösliche Vliesstoff, insbesondere der Wirrlage Vliesstoff, ein Flächengewicht von 40 bis 200 g/m2, vorzugsweise von 60 bis 180 g/m2 und insbesondere von 80 bis 160 g/m2 aufweist. With regard to the optical, haptic and mechanical properties of the detergent portion unit, it has proven to be advantageous if the water-soluble nonwoven, in particular the randomly oriented nonwoven, has a basis weight of 40 to 200 g/m 2 , preferably 60 to 180 g/m 2 and in particular from 80 to 160 g/m 2 .
In einer weiteren bevorzugten Variante der Waschmittelportionseinheit handelt es sich bei den wasserlöslichen Vliesstoffen um Stoffschlussvliesstoffe. In diesen Vliesstoffen wird die Verbindung der Fasern durch Stoffschluss durch Zusatzstoffe hergestellt. Diese Bindemittel ermöglichen die adhäsive Verbindung der Fasern miteinander. In a further preferred variant of the detergent portion unit, the water-soluble nonwovens are bonded nonwovens. In these non-woven fabrics, the fibers are bonded by bonding through additives. These binders enable the fibers to be adhesively bonded to one another.
Aufgrund ihrer Eigenschaften besonders bevorzugt sind neben den Wirrlage Vliesstoffen wasserlösliche Vliesstoff aus der Gruppe der Kreuzlage Vliesstoffe. Die Herstellung dieser Vliese erfolgt beispielsweise durch Ablegen der Fasern auf einem Ablageband mit einer Längsorientierung der Fasern zum Gesamtvlies, wobei die Fasern vorzugsweise in zwei Richtungen orientiert sind. Kreuzlage Vliesstoffe unterscheiden sich optisch wie haptisch ebenfalls von den üblicherweise zur Herstellung von Waschmittelportionseinheiten eingesetzten wasserlöslichen Folien sind darüber hinaus jedoch in besserer Weise als die Wirrlage Vliesstoffe zur Bedruckung geeignet. Because of their properties, water-soluble nonwovens from the group of cross-ply nonwovens are particularly preferred in addition to randomly plied nonwovens. These fleeces are produced, for example, by depositing the fibers on a depositing belt with the fibers oriented longitudinally relative to the overall fleece, with the fibers preferably being oriented in two directions. Cross-ply nonwovens also differ both visually and haptically from the water-soluble films usually used to produce detergent portion units, but are also more suitable for printing than random-ply nonwovens.
In Bezug auf die drucktechnischen Eigenschaften der Waschmittelportionseinheit hat es sich als vorteilhaft erweisen, wenn der wasserlösliche Vliesstoff, insbesondere der Kreuzlage Vliesstoff, ein
Flächengewicht von 30 bis 80 g/m2, vorzugsweise von 33 bis 70 g/m2 und insbesondere von 36 bis 70 g/m2 aufweist. With regard to the printing properties of the detergent portion unit, it has proven to be advantageous if the water-soluble nonwoven, in particular the cross-ply nonwoven, a basis weight of 30 to 80 g/m 2 , preferably 33 to 70 g/m 2 and in particular 36 to 70 g/m 2 .
Neben den zuvor genannten wasch- oder reinigungsaktive Inhaltsstoffen können die wasserlöslichen Vliesstoffe, insbesondere die Fasern der wasserlöslichen Vliesstoffe weitere für die Produktwirkung relevante Aktivstoffe enthalten. Zur Gruppe dieser Aktivstoffe zählen beispielsweise die Farbstoffe. Durch den Zusatz von Farbstoffen zu den Fasern der wasserlöslichen Vliesstoffe kann die Optik der Waschmittelportionseinheit verändert werden. Gleichzeitig kann durch die Farbgebung eine direkt oder indirekt farbbasierte Produktkommunikation ermöglicht werden. In addition to the washing- or cleaning-active ingredients mentioned above, the water-soluble nonwovens, in particular the fibers of the water-soluble nonwovens, can contain other active substances relevant to the effect of the product. The group of these active substances includes, for example, the dyes. By adding dyes to the fibers of the water-soluble nonwovens, the appearance of the detergent portion unit can be changed. At the same time, the coloring can enable direct or indirect color-based product communication.
Eine direkt farbbasierte Produktkommunikation wird beispielsweise durch Signalfarben ermöglicht, welche den Verbraucher auf eine spezielle Produktwirkung hinweisen. Eine solche direkte Produktkommunikation ist beispielsweise in Gebinden hilfreich, welche mehrere Waschmittelportionseinheiten mit unterschiedlicher Wirkung umfassen, beispielsweise Waschmittelportionseinheiten zur Textilreinigung in Kombination mit Waschmittelportionseinheiten zur Textilpflege, und jeder dieser Wirkungen eine spezifische Farbe zugewiesen ist. Direct color-based product communication is made possible, for example, by signal colors that draw the consumer's attention to a special product effect. Such direct product communication is helpful, for example, in containers that comprise several detergent portion units with different effects, for example detergent portion units for textile cleaning in combination with detergent portion units for textile care, and each of these effects is assigned a specific color.
Eine indirekt farbbasierte Produktkombination beschreibt beispielsweise die Produktkombination mittels eines Aufdrucks auf die wasserlösliche Umhüllung der Waschmittelportionseinheit, welche aufgrund der den Aufdruck umgebenden Farbe der wasserlöslichen Umhüllung besonders auffällig oder gut lesbar ist. Die Variation der Grundfarbe der wasserlöslichen Umhüllung ermöglicht auf diese Weise eine Ausweitung der Auswahl von zur Bedruckung der wasserlöslichen Umhüllung verfügbaren Druckfarben. An indirectly color-based product combination describes, for example, the product combination by means of an imprint on the water-soluble casing of the detergent portion unit, which is particularly noticeable or easily legible due to the color of the water-soluble casing surrounding the imprint. Varying the base color of the water-soluble casing in this way enables the range of inks available for printing on the water-soluble casing to be expanded.
Aufgrund ihrer optischen Eigenschaften und ihrer einfacheren Herstellung sind bevorzugte wasserlösliche Vliesstoffe weiß, also nicht farbig. Die weiße Farbe des wasserlöslichen Vliesstoffes eignet sich in besonderer Weise zur Bedruckung. Eine weitere für Bedruckung und deren Wahrnehmung relevantes Merkmal des Vliesstoffs ist, wie bereits zuvor ausgeführt, dessen besondere, von dem eines üblichen wasserlöslichen Films abweichende Oberflächeneigenschaft. Bevorzugte Waschmittelportionseinheiten sind folglich dadurch gekennzeichnet, dass der wasserlösliche Vliesstoff auf seiner Außenseite bedruckt ist. Due to their optical properties and their simpler production, preferred water-soluble nonwovens are white, ie not colored. The white color of the water-soluble non-woven fabric is particularly suitable for printing. Another feature of the nonwoven material that is relevant for printing and how it is perceived is, as already mentioned, its special surface property, which differs from that of a conventional water-soluble film. Preferred detergent portion units are consequently characterized in that the water-soluble nonwoven is printed on its outside.
Insbesondere in Kombination mit einem weißen oder einem bedruckten weißen Vliesstoff hat sich der Einsatz transparenter wasserlöslicher Filme als Bestandteil der wasserlöslichen Umhüllung als vorteilhaft erwiesen. Selbstverständlich ist es möglich, auch diesen wasserlöslichen Film zu bedrucken. The use of transparent, water-soluble films as a component of the water-soluble cover has proven advantageous, particularly in combination with a white or a printed white nonwoven fabric. Of course, it is also possible to print on this water-soluble film.
Die bereits eingangs in Bezug auf ihre physikalischen Eigenschaften und die zu ihrer Herstellung eingesetzten Verfahren beschriebenen festen Wasch- oder Reinigungsmittel können ebenso wie die wasserlöslichen Vliesstoffe wasch- oder reinigungsaktiven Inhaltsstoffe enthalten, wobei
wasch- oder reinigungsaktive Inhaltstoffe aus der Gruppe der Gerüststoffe, Tenside, waschaktiven Polymere, Enzyme, Bleichmittel und Duftstoffe besonders bevorzugt sind. The solid detergents or cleaning agents already described at the outset in relation to their physical properties and the processes used for their production can, like the water-soluble nonwovens, contain active washing or cleaning ingredients washing- or cleaning-active ingredients from the group consisting of builders, surfactants, washing-active polymers, enzymes, bleaching agents and fragrances are particularly preferred.
Eine Gruppe wasch- oder reinigungsaktiver Inhaltsstoffe, für deren die Konfektionierung mittels der erfindungsgemäßen Waschmittelportionseinheiten besondere Vorteile bieten, sind die die Bleichmittel, insbesondere die Sauerstoffbleichmittel. Entsprechende Waschmittelportionseinheit, bei denen das feste Wasch- oder Reinigungsmittel mindestens einen wasch- oder reinigungsaktiven Inhaltsstoff aus der Gruppe der Bleichmittel, vorzugsweise der Sauerstoffbleichmittel umfasst, sind daher bevorzugt. One group of washing- or cleaning-active ingredients for which the packaging by means of the detergent portion units according to the invention offers particular advantages are the bleaches, in particular the oxygen bleaches. Corresponding detergent portion units in which the solid detergent or cleaning agent comprises at least one detergent-active ingredient from the group of bleaching agents, preferably oxygen bleaching agents, are therefore preferred.
Unter einem Bleichmittel sind insbesondere solche Verbindungen zu verstehen, die in wässrigem Medium Wasserstoffperoxid liefern. Unter den als Bleichmittel dienenden, in Wasser H2O2 liefernden Verbindungen haben das Natriumpercarbonat, das Natriumperborattetrahydrat und das Natriumperboratmonohydrat besondere Bedeutung. Weitere brauchbare Bleichmittel sind beispielsweise Peroxopyrophosphate, Citratperhydrate sowie H2O2 liefernde persaure Salze oder Persäuren, wie Persulfate beziehungsweise Perschwefelsäure. Brauchbar ist auch das Harnstoffperoxohydrat Percarbamid, das durch die Formel H2N-CO-NH2 H2O2 beschrieben werden kann. Insbesondere beim Einsatz der Mittel für das Reinigen harter Oberflächen, zum Beispiel beim maschinellen Geschirrspülen, können die Waschmittelportionseinheiten gewünschtenfalls auch Bleichmittel aus der Gruppe der organischen Bleichmittel enthalten, obwohl deren Einsatz prinzipiell auch bei Mitteln für die Textilwäsche möglich ist. Typische organische Bleichmittel sind die Diacylperoxide, wie zum Beispiel Dibenzoylperoxid. Weitere typische organische Bleichmittel sind die Peroxysäuren, wobei als Beispiele besonders die Alkylperoxysäuren und die Arylperoxysäuren genannt werden. Bevorzugte Vertreter sind (a) die Peroxybenzoesäure und ihre ringsubstituierten Derivate, wie Alkylperoxybenzoesäuren, aber auch Peroxy-a-Naphthoesäure und Magnesium-monoperphthalat, (b) die aliphatischen oder substituiert aliphatischen Peroxysäuren, wie Peroxylaurinsäure, Peroxystearinsäure, e-Phthalimidoperoxycapronsäure (Phthalimidoperoxy- hexansäure, PAP), o-Carboxybenzamidoperoxycapronsäure, N-Nonenylamidoperadipinsäure und N-Nonenylamidopersuccinate, und (c) aliphatische und araliphatische Peroxydicarbonsäuren, wie 1 ,12-Diperoxycarbonsäure, 1 ,9-Diperoxyazelainsäure, Diperoxysebacinsäure, Diperoxybrassyl- säure, die Diperoxyphthalsäuren, 2-Decyldiperoxybutan-1 ,4-disäure, N,N-Terephthaloyl-di(6- aminopercapronsäure). Das Sauerstoffbleichmittel ist vorzugsweise aus der Gruppe Natriumpercarbonat und s-Phthalimidoperoxycapronsäure, besonders bevorzugt aus der Gruppe Natriumpercarbonat ausgewählt. Bevorzugte Sauerstoffbleichmittel sind in partikulärer Form konfektioniert, wobei die Partikel eine Beschichtung aufweisen. A bleaching agent is to be understood in particular as meaning those compounds which deliver hydrogen peroxide in an aqueous medium. Sodium percarbonate, sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance among the compounds that serve as bleaching agents and produce H2O2 in water. Other usable bleaching agents are, for example, peroxopyrophosphates, citrate perhydrates and peracid salts or peracids which supply H2O2, such as persulfates or persulfuric acid. The urea peroxohydrate percarbamide, which can be described by the formula H2N-CO-NH2H2O2, can also be used. In particular when using the agents for cleaning hard surfaces, for example in machine dishwashing, the detergent portion units can also contain bleaches from the group of organic bleaches if desired, although their use is in principle also possible for agents for textile washing. Typical organic bleaches are the diacyl peroxides, such as dibenzoyl peroxide. Other typical organic bleaches are the peroxyacids, examples being the alkylperoxyacids and the arylperoxyacids. Preferred representatives are (a) peroxybenzoic acid and its ring-substituted derivatives, such as alkylperoxybenzoic acids, but also peroxy-a-naphthoic acid and magnesium monoperphthalate, (b) the aliphatic or substituted aliphatic peroxyacids, such as peroxylauric acid, peroxystearic acid, e-phthalimidoperoxycaproic acid (phthalimidoperoxyhexanoic acid , PAP), o-carboxybenzamidoperoxycaproic acid, N-nonenylamidoperadipic acid and N-nonenylamidopersuccinate, and (c) aliphatic and araliphatic peroxydicarboxylic acids, such as 1,12-diperoxycarboxylic acid, 1,9-diperoxyazelaic acid, diperoxysebacic acid, diperoxybrassylic acid, the diperoxyphthalic acids, 2-decyldiperoxybutane -1,4-dioic acid, N,N-terephthaloyl-di(6-aminopercaproic acid). The oxygen bleach is preferably selected from the group consisting of sodium percarbonate and s-phthalimidoperoxycaproic acid, more preferably from the group consisting of sodium percarbonate. Preferred oxygen bleaches are formulated in particulate form, with the particles having a coating.
Bleichmittel, insbesondere Sauerstoffbleichmittel, neigen bei Lagerung trotz üblicher Stabilisierungsmaßnahmen wie dem Einsatz von Beschichtungen, insbesondere während der Lagerung bei erhöhten Temperaturen oder erhöhter Luftfeuchtigkeit zur Zersetzung und
Gasfreisetzung. Die Gasfreisetzung aus diesen Bleichmitteln ist mit der Konfektionierung in vollständig verschlossenen Behältern in der Regel nicht vereinbar, weshalb wasserlösliche Behälter für Wasch- oder Reinigungsmittel des Standes der Technik üblicherweise Perforationen aufweisen, welche einen Gasaustausch zwischen dem Inneren des Behälters und der umgebenden Atmosphäre ermöglichen. Auf derartige Perforationen kann bei Einsatz der erfindungsgemäßen Waschmittelportionseinheiten aufgrund der Gasdurchlässigkeit des eingesetzten wasserlöslichen Vliesstoffes verzichtet werden. Bleaching agents, in particular oxygen bleaching agents, tend to decompose and decompose during storage, despite customary stabilization measures such as the use of coatings, in particular during storage at elevated temperatures or elevated atmospheric humidity gas release. The release of gas from these bleaches is generally not compatible with packaging in completely sealed containers, which is why water-soluble containers for detergents or cleaning agents of the prior art usually have perforations that allow gas exchange between the interior of the container and the surrounding atmosphere. Such perforations can be dispensed with when using the detergent portion units according to the invention due to the gas permeability of the water-soluble nonwoven fabric used.
Bevorzugte Waschmittelportionseinheit, sind dadurch gekennzeichnet, dass das feste Wasch- oder Reinigungsmittel mindestens einen wasch- oder reinigungsaktiven Inhaltsstoff aus der Gruppe der Sauerstoffbleichmittel umfasst, wobei der Gewichtsanteil des Sauerstoffbleichmittels am Gesamtgewicht des festen Wasch- oder Reinigungsmittels 2 bis 60 Gew.-%, vorzugsweise 4 bis 40 Gew.-% beträgt. Preferred detergent portion units are characterized in that the solid detergent or cleaning agent comprises at least one active detergent or cleaning ingredient from the group of oxygen bleaches, the proportion by weight of the oxygen bleaching agent in the total weight of the solid detergent or cleaning agent being 2 to 60% by weight, preferably is 4 to 40% by weight.
Eine zweite Gruppe wasch- oder reinigungsaktiver Inhaltsstoffe, aus deren Konfektionierung mittels der erfindungsgemäßen Waschmittelportionseinheiten sich Vorteile ergeben, sind die Duftstoffe. Bevorzugte Waschmittelportionseinheiten sind daher dadurch gekennzeichnet, dass das feste Wasch- oder Reinigungsmittel mindestens einen wasch- oder reinigungsaktiven Inhaltsstoff aus der Gruppe der Duftstoffe umfasst. In bevorzugten Waschmittelportionseinheiten beträgt der Gewichtsanteil des Duftstoffs am Gesamtgewicht des festen Wasch- oder Reinigungsmittels 0,1 bis 10 Gew.-%, vorzugsweise 0,2 bis 6 Gew.-%. A second group of washing or cleaning-active ingredients, the packaging of which results in advantages using the detergent portion units according to the invention, are the fragrances. Preferred washing agent portion units are therefore characterized in that the solid washing or cleaning agent comprises at least one washing or cleaning active ingredient from the group of fragrances. In preferred detergent portion units, the proportion by weight of the fragrance in the total weight of the solid detergent or cleaning agent is 0.1 to 10% by weight, preferably 0.2 to 6% by weight.
Bei einem Duftstoff handelt es sich um eine den Geruchsinn anregende, chemische Substanz. Um den Geruchssinn anregen zu können, sollte die chemische Substanz zumindest teilweise in der Luft verteilbar sein, d.h. der Duftstoff sollte bei 25°C zumindest in geringem Maße flüchtig sein. Ist der Duftstoff nun sehr flüchtig, klingt die Geruchsintensität dann schnell wieder ab. Bei einer geringeren Flüchtigkeit ist der Gerucheindruck jedoch nachhaltiger, d.h. er verschwindet nicht so schnell. In einer Ausführungsform weist der Duftstoff daher einen Schmelzpunkt auf, der im Bereich von -100°C bis 100°C, bevorzugt von -80°C bis 80°C, noch bevorzugter von -20°C bis 50°C, insbesondere von -30°C bis 20°C liegt. In einerweiteren Ausführungsform weist der Duftstoff einen Siedepunkt auf, der im Bereich von 25°C bis 400°C, bevorzugt von 50°C bis 380°C, mehr bevorzugt von 75°C bis 350°C, insbesondere von 100°C bis 330°C liegt. A fragrance is a chemical substance that stimulates the sense of smell. In order to be able to stimulate the sense of smell, the chemical substance should be at least partially airborne, i.e. the fragrance should be at least slightly volatile at 25°C. If the fragrance is now very volatile, the odor intensity then quickly fades away. With a lower volatility, however, the odor impression is more lasting, i.e. it does not disappear as quickly. In one embodiment, the fragrance therefore has a melting point in the range from -100°C to 100°C, preferably from -80°C to 80°C, more preferably from -20°C to 50°C, in particular from - 30°C to 20°C. In a further embodiment, the fragrance has a boiling point in the range from 25°C to 400°C, preferably from 50°C to 380°C, more preferably from 75°C to 350°C, in particular from 100°C to 330 °C.
Insgesamt sollte eine chemische Substanz eine bestimmte Molekülmasse nicht überschreiten, um als Duftstoff zu fungieren, da bei zu hoher Molekülmasse die erforderliche Flüchtigkeit nicht mehr gewährleitstet werden kann. In einer Ausführungsform weist der Duftstoff eine Molekülmasse von 40 bis 700 g/mol, noch bevorzugter von 60 bis 400 g/mol auf.
Als Duftstoffe können einzelne Riechstoffverbindungen, z.B. die synthetischen Produkte vom Typ der Ester, Ether, Aldehyde, Ketone, Alkohole und Kohlenwasserstoffe verwendet werden. Overall, a chemical substance should not exceed a specific molecular mass in order to function as a fragrance, since the required volatility can no longer be guaranteed if the molecular mass is too high. In one embodiment, the fragrance has a molecular mass of 40 to 700 g/mol, more preferably 60 to 400 g/mol. Individual fragrance compounds, for example synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, can be used as fragrances.

In einer entsprechenden Ausführungsform wird zumindest ein Teil des Duftstoffs in verkapselter Form (Duftstoffkapseln), insbesondere in Mikrokapseln, eingesetzt. Es kann aber auch der gesamte Duftstoff in verkapselter Form eingesetzt werden. Bei den Mikrokapseln kann es sich um wasserlösliche und/oder wasserunlösliche Mikrokapseln handeln. Es können beispielsweise Melamin-Harnstoff-Formaldehyd-Mikrokapseln, Melamin-Formaldehyd-Mikrokapseln, Harnstoff- Formaldehyd-Mikrokapseln oder Stärke-Mikrokapseln eingesetzt werden. „Duftstoffvorläufer“ bezieht sich auf Verbindungen, die erst nach chemischer Umwandlung/Spaltung, typischerweise durch Einwirkung von Licht oder anderen Umgebungsbedingungen, wie pH-Wert, Temperatur, etc., den eigentlichen Duftstoff freisetzen. Derartige Verbindungen werden häufig auch als Duftspeicherstoffe oder „Pro-Fragrance“ bezeichnet. In a corresponding embodiment, at least part of the fragrance is used in encapsulated form (fragrance capsules), in particular in microcapsules. However, the entire fragrance can also be used in encapsulated form. The microcapsules can be water-soluble and/or water-insoluble microcapsules. For example, melamine-urea-formaldehyde microcapsules, melamine-formaldehyde microcapsules, urea-formaldehyde microcapsules or starch microcapsules can be used. “Pro-fragrance” refers to compounds that only release the actual fragrance after chemical conversion/cleavage, typically through exposure to light or other environmental conditions such as pH, temperature, etc. Such compounds are often also referred to as fragrance storage substances or “pro-fragrance”.
Die Gasdurchlässigkeit der für die erfindungsgemäßen Waschmittelportionseinheiten kennzeichnenden wasserlöslichen Vliesstoffe vergrößert die Vielfalt der mit Hilfe der Waschmittelportionseinheiten realisierbaren Dufteindrücke. Dabei ist nicht nur der unmittelbare Dufteindruck der Waschmittelportionseinheit in unerwarteter Weise modifizierbar. Darüber hinaus ist der Dufteindruck des mit dem festen Wasch- oder Reinigungsmittel behandelten Substrats,
beispielsweise eines textilen Gewebes, mit einer gegenüber herkömmlichen wasserlöslichen Waschmittelportionseinheiten verminderten Duftstoffmenge erzielbar. The gas permeability of the water-soluble nonwovens characteristic of the detergent portion units according to the invention increases the variety of scent impressions that can be achieved with the aid of the detergent portion units. It is not only the immediate scent impression of the detergent portion unit that can be modified in an unexpected way. In addition, the scent impression of the substrate treated with the solid detergent or cleaning agent, for example a textile fabric, can be achieved with a reduced quantity of fragrance compared to conventional water-soluble detergent portion units.
Bevorzugte feste Wasch- oder Reinigungsmittel umfassen sowohl freie als auch verkapselte Duftstoffe. Während die freien Duftstoffe aufgrund der Durchlässigkeit des wasserlöslichen Vliesgewebes für den Benutzer unmittelbar wahrnehmbar sind, bilden die verkapselten Duftstoffe die Grundlage des nach Gebrauch auf dem behandelten Substrat realisierten Dufteindrucks. Als besonders vorteilhaft es sich erwiesen, wenn das Gewichtsverhältnis des freien Duftstoffs zu dem in verkapselter Form vorliegenden Duftstoffs zwischen 2:1 und 1 :8, vorzugweise zwischen 1 :1 und 1 :6 vorliegt. Als „Gewicht“ wird dabei jeweils das tatsächliche Gewicht der duftenden Verbindung ohne Berücksichtigung etwaiger Hilfsstoffe oder Kapselmaterialien verstanden. Preferred solid detergents or cleaning agents include both free and encapsulated fragrances. While the user can immediately perceive the free fragrances due to the permeability of the water-soluble fleece fabric, the encapsulated fragrances form the basis of the fragrance impression realized on the treated substrate after use. It has proven particularly advantageous if the weight ratio of the free fragrance to the fragrance present in encapsulated form is between 2:1 and 1:8, preferably between 1:1 and 1:6. “Weight” is understood to mean the actual weight of the fragrant compound without taking into account any auxiliary substances or capsule materials.
Eine weitere Gruppe bevorzugter Inhaltsstoffe des festen Wasch- oder Reinigungsmittels bilden die textilpflegenden Verbindungen. Bevorzugte Waschmittelportionseinheiten enthalten, bezogen auf ihr Gesamtgewicht 0,2 bis 30 Gew.-%, vorzugsweise 0,5 bis 20 Gew.-% und insbesondere 1 bis 15 Gew.-% textilpflegende Verbindung. Another group of preferred ingredients of the solid washing or cleaning agent is formed by the textile care compounds. Preferred detergent portion units contain, based on their total weight, from 0.2 to 30% by weight, preferably from 0.5 to 20% by weight and in particular from 1 to 15% by weight of a textile-care compound.
Die Gruppe der textilpflegenden Verbindungen umfasst vorzugsweise insbesondere kationische Tenside; amphotere Tenside; kationischen Polymere; The group of textile care compounds preferably includes, in particular, cationic surfactants; amphoteric surfactants; cationic polymers;

Es ist insbesondere bevorzugt, wenn die textilpflegende Verbindung aus Polysiloxanen, Textilweichmachenden Tonen, kationischen Polymeren und Mischungen daraus ausgewählt ist. It is particularly preferred if the fabric care compound is selected from polysiloxanes, fabric softening clays, cationic polymers and mixtures thereof.
Der Einsatz von Polysiloxanen und/oder kationischen Polymeren als textilpflegende Verbindung in der Zusammensetzung ist vorteilhaft, da diese nicht nur einen weichmachenden Effekt zeigen, sondern auch den Parfümeindruck auf der Wäsche verstärken. The use of polysiloxanes and/or cationic polymers as a textile-care compound in the composition is advantageous, since these not only have a softening effect, but also enhance the perfume impression on the laundry.
Der Einsatz von weichmachenden Tonen als textilpflegende Verbindung in der Zusammensetzung ist vorteilhaft, da diese zusätzlich einen Wasser-enthärtenden Effekt aufweisen und so beispielsweise Kalkablagerungen auf der Wäsche verhindert werden können. Um eine optimale Leistung zu erzielen, kann es bevorzugt sein, dass die Zusammensetzung eine Kombination von wenigstens zwei textilpflegenden Verbindungen enthält. The use of softening clays as a textile-care compound in the composition is advantageous since they also have a water-softening effect and can thus, for example, prevent limescale deposits on the laundry. In order to achieve optimal performance it may be preferred that the composition contains a combination of at least two fabric care compounds.
