Description
WO 01/83667 PCT/[JSOl/07708 MULTI-COMPARTMENT POUCH COMPRISING SEPARATE SOLID AND
LIQUID COMPONENTS
Field of the Invention This invention relates to a pouch made from a water-soluble film and having at least two compartments.
BackQround to the Invention Laundry detergent products can be found on the market to date in various forms, such as solid granular compositions and tablets, or liquid compositions. This gives the consumer a choice of detergent products they can use.
Some detergent ingredients currently used by the laundry industry, are preferably manufactured and processed in liquid form. These liquid ingredients are difficult or costly to include in a solid detergent composition. Also, certain ingredients are preferably transported and supplied to detergent manufacturers in a liquid form and require additional, and sometimes costly, process steps to enable them to be included in a solid detergent composition. An example of these detergent ingredients are surfactants, especially nonionic surfactants which are typically liquid at room temperature or are typically transported and supplied to detergent manufacturers in liquid form.
Current methods of incorporating liquid ingredients into solid detergent compositions include absorbing the liquid ingredient onto a solid carrier, for example by mixing, agglomeration or spray-on techniques. Typically, solid detergent compositions comprise only low amounts of these liquid detergent ingredients due to the difficulty and expense of incorporating these liquid ingredients into a solid detergent.
However, it is desirable to include higher levels of liquid ingredients such as certain surfactant or solutions thereof in a detergent composition with a substantial amount of solid detergent ingredients. It is also desirable to be able to incorporate detergent wo 01/83667 PCT/USO1/07708 ingredients that are typically transported and supplied in liquid form in a detergent composition comprising a substantial amount of solid detergent ingredients without the need for extra costly and difficult processing steps.
The inventors have found that by using a multi-compartment water-soluble pouch comprising at least two compartments, liquid detergent ingredients such as surfactants can be included in a detergent composition comprising other solid detergent ingredients, without the need for difficult, costly manufacturing and processing steps to incorporate said liquid ingredient as a solid in the solid detergent. The liquid detergent ingredients are comprised by one compartment of a multi-compartment pouch whilst the solid detergent ingredients are comprised by a second compartment.
Summary of the Invention The present invention provides a multi-compartment pouch made from a water-soluble film and having at least two compartments, wherein said multi-compartment pouch comprises a composition comprising a solid component and a liquid component, wherein; (a) a first compartment comprises the liquid component, wherein said liquid component comprises at least 70%, by weight of the liquid component, surfactant and 2% to 3%, by weight of the liquid component, water; and (b) a second compartment comprises the solid component.
Detailed Description of the Invention Multi-compartrnent pouch and materials thereof The multi-compartment pouch of the invention, herein referred to as "pouch", comprises at least two compartments. The pouch herein is typically a closed structure, made of materials described herein, enclosing a volume space which is separated into at least two, preferably two compartments. The pouch comprises a composition comprising a solid component and a liquid component. The pouch can be of any form, shape and material which is suitable to hold the composition, e.g. without allowing the release of the composition from the pouch prior to contact of the pouch to water. The exact execution will depend on for example the type and amount of the composition in the pouch, the number of compartments in the pouch, the characteristics required from the pouch to hold, protect and deliver or release the compositions.
The pouch may be of such a size that it conveniently contains either a unit dose amount of the composition herein, suitable for the required operation, for example one wash, or only a partial dose, to allow the consumer greater flexibility to vary the amount used, for example depending on the size and/or degree of soiling of the wash load.
The pouch is made from a water-soluble film which encloses an inner volume, said inner volume is divided into the compartments of the pouch.
The compartments of the pouch herein are closed structures, made from a water-soluble film which enclose a volume space which comprises the solid component or the liquid component of the composition. Said volume space is preferably enclosed by a water-soluble film in such a manner that the volume space is separated from the outside environment.
The solid or liquid component that are comprised by the compartment of the pouch are contained in the volume space of the compartment, and are separated from the outside environment by a barrier of water-soluble film.
The term "separated" means for the purpose of this invention "physically distinct, in that a first ingredient comprised by a compartment is prevented from contacting a second ingredient if said second ingredient is not comprised by the same compartment which comprises said first ingredient".
The term "outside environment" means for the purpose of this invention "anything which cannot pass through the water-soluble film which encloses the compartment and which is not comprised by the compartment".

Detailed Description of the Invention Multi-compartrnent pouch and materials thereof The multi-compartment pouch of the invention, herein referred to as "pouch", comprises at least two compartments. The pouch herein is typically a closed structure, made of materials described herein, enclosing a volume space which is separated into at least two, preferably two compartments. The pouch comprises a composition comprising a solid component and a liquid component. The pouch can be of any form, shape and material which is suitable to hold the composition, e.g. without allowing the release of the composition from the pouch prior to contact of the pouch to water. The exact execution will depend on for example the type and amount of the composition in the pouch, the number of compartments in the pouch, the characteristics required from the pouch to hold, protect and deliver or release the compositions.
The pouch may be of such a size that it conveniently contains either a unit dose amount of the composition herein, suitable for the required operation, for example one wash, or only a partial dose, to allow the consumer greater flexibility to vary the amount used, for example depending on the size and/or degree of soiling of the wash load.
The pouch is made from a water-soluble film which encloses an inner volume, said inner volume is divided into the compartments of the pouch.
The compartments of the pouch herein are closed structures, made from a water-soluble film which enclose a volume space which comprises the solid component or the liquid component of the composition. Said volume space is preferably enclosed by a water-soluble film in such a manner that the volume space is separated from the outside environment.
The solid or liquid component that are comprised by the compartment of the pouch are contained in the volume space of the compartment, and are separated from the outside environment by a barrier of water-soluble film.
The term "separated" means for the purpose of this invention "physically distinct, in that a first ingredient comprised by a compartment is prevented from contacting a second ingredient if said second ingredient is not comprised by the same compartment which comprises said first ingredient".
The term "outside environment" means for the purpose of this invention "anything which cannot pass through the water-soluble film which encloses the compartment and which is not comprised by the compartment".
The compartment is suitable to hold the solid or liquid component, e.g.
without allowing the release of the components from the compartment prior to contact of the pouch to water. The compartment can have any form or shape, depending on the nature of the material of the compartment, the nature of the components or composition, the intended use, amount of the components etc.
It may be preferred that the compartment which comprises the liquid component also comprises an air bubble, preferably the air bubble has a volume of no more than 50%, preferably no more than 40%, more preferably no more than 30%, more preferably no more than 20%, more preferably no more than 10% of the volume space of said compartment. Without being bound by theory, it is believed that the presence of the air bubble increases the tolerance of the pouch to the movement of liquid component within the compartment, thus reducing the risk of the liquid component leaking from the compartment.
The pouch is made from a water-soluble film, said water-soluble film typically has a solubility of at least 50%, preferably at least 75% or even at least 95%, as measured by the method set out hereinafter using a glass-filter with a maximum pore size of 50 microns, namely:
Gravimetric method for determining water-solubility of the material of the compartment and/or pouch:
10 grams 0.1 gram of material is added in a 400 ml beaker, whereof the weight has been determined, and 245m1 lml of distilled water is added. This is stirred vigorously on magnetic stirrer set at 600 rpm, for 30 minutes. Then, the mixture is filtered through a folded qualitative sintered-glass filter with the pore sizes as defined above (max. 50 micron). The water is dried off from the collected filtrate by any conventional method, and the weight of the remaining polymer is determined (which is the dissolved or dispersed fraction). Then, the % solubility or dispersability can be calculated.
Preferred films are polymeric materials, preferably polymers which are formed into a film or sheet. The film can for example be obtained by casting, blow-moulding, extrusion or blow extrusion of the polymer material, as known in the art. Preferred polymers, copolymers or derivatives thereof are selected from polyvinyl alcohols, polyvinyl 5 pyrrolidone, polyalkylene oxides, acrylamide, acrylic acid, cellulose, cellulose ethers, cellulose esters, cellulose amides, polyvinyl acetates, polycarboxylic acids and salts, polyaminoacids or peptides, polyamides, polyacrylamide, copolymers of maleic/acrylic acids, polysaccharides including starch and gelatine, natural gums such as xanthum and carragum. More preferably the polymer is selected from polyacrylates and water-soluble acrylate copolymers, methylcellulose, carboxymethylcellulose sodium, dextrin, ethylcellulose, hydroxyethyl cellulose, hydroxypropyl methylcellulose, maltodextrin, polymethacrylates, most preferably polyvinyl alcohols, polyvinyl alcohol copolymers and hydroxypropyl methyl cellulose (HPMC). Preferably, the level of polymer in the film, for example a PVA polymer, is at least 60%.
The polymer can have any weight average molecular weight, preferably from about 1000 to 1,000,000, or even form 10,000 to 300,000 or even form 15,000 to 200,000 or even form 20,000 to 150,000.
Mixtures of polymers can also be used. This may in particular be beneficial to control the mechanical and/or dissolution properties of the compartments or pouch, depending on the application thereof and the required needs. For example, it may be preferred that a mixture of polymers is present in the film, whereby one polymer material has a higher water-solubility than another polymer material, and/or one polymer material has a higher mechanical strength than another polymer material. It may be preferred that a mixture of polymers is used, having different weight average molecular weights, for example a mixture of PVA or a copolymer thereof of a weight average molecular weight of 10,000-40,000, preferably around 20,000, and of PVA or copolymer thereof, with a weight average molecular weight of about 100,000 to 300,000, preferably around 150,000.
Also useful are polymer blend compositions, for example comprising hydrolytically degradable and water-soluble polymer blend such as polylactide and polyvinyl alcohol, achieved by the mixing of polylactide and polyvinyl alcohol, typically comprising 1-35%
by weight polylactide and approximately from 65% to 99% by weight polyvinyl alcohol, if the material is to be water-soluble.
It may be preferred that the polymer present in the film is from 60% to 98%
hydrolysed, preferably 80% to 90%, to improve the dissolution of the material.
Most preferred are films which comprise a PVA polymer with similar properties to the film which comprises a PVA polymer and is known under the trade reference M8630, as sold by Chris-Craft Industrial Products of Gary, Indiana, US.
The film herein may comprise other additive ingredients than the polymer or polymer material. For example, it may be beneficial to add plasticisers, for example glycerol, ethylene glycol, diethyleneglycol, propylene glycol, sorbitol and mixtures thereof, additional water, disintegrating aids. It may be useful when the pouched composition is a detergent composition, that the pouch or compartment material itself comprises a detergent additive to be delivered to the wash water, for example organic polymeric soil release agents, dispersants, dye transfer inhibitors.
The compartments and preferably pouch as a whole are made from water-soluble film.
Suitable examples of commercially available water-soluble films include polyvinyl alcohol and partially hydrolysed polyvinyl acetate, alginates, cellulose ethers such as carboxymethylcellulose and methylcellulose, polyethylene oxide, polyacrylates and combinations of these.
Composition The pouch comprises a composition, typically said composition is contained in the volume space of the pouch.
without allowing the release of the components from the compartment prior to contact of the pouch to water. The compartment can have any form or shape, depending on the nature of the material of the compartment, the nature of the components or composition, the intended use, amount of the components etc.
It may be preferred that the compartment which comprises the liquid component also comprises an air bubble, preferably the air bubble has a volume of no more than 50%, preferably no more than 40%, more preferably no more than 30%, more preferably no more than 20%, more preferably no more than 10% of the volume space of said compartment.
