Description

DISHWASHER DETERGENT SHAPED BODIES WITH SPECIFIC
GEOMETRY
This invention relates to detersive shaped bodies, primarily tablets, such as dishwasher tablets, laundry detergent tablets, bleach tablets, stain remover tablets or water softening tablets, for use in the home, more particularly for use in machines, to a process for their production and to their use.
Detersive shaped bodies, more particularly tablets, have a number of advantages over powder-form compositions, such as easy handling, simple dosage and low packaging volumes.
Unfortunately, problems arise out of the fact that, to achieve adequate dimensional stability and fracture resistance, relatively high pressures have to be applied in the compression of the powder-form ingredients. In view of the heavy compaction which they undergo, corresponding tablets often show inadequate storage stability in regard to sensitive ingredients (bleaching agent, perfume, enzymes, silver protectors, dyes, surfactants), reduced performance (particularly against such soils as tea, milk, starch) by comparison with comparable amounts of active ingredient made up in another form, occasionally inadequate protection of sensitive materials to be cleaned and impaired disintegration and dissolving properties in use.
According to some patents belonging to the prior art, some of these problems are said to have been solved.
In many cases, however, the consumer is unable to reproduce the performance advantages described in those documents. Accordingly, an important problem confronting manufacturers of detersive shaped bodies is to satisfy the consumer.
Accordingly, the problem addressed by the present invention was to provide high-performance, easy-to-handle detersive shaped bodies, above all dishwasher tablets, laundry detergent tablets, stain remover tablets or water softener tablets for use in the home, more particularly for use in machines, with high storage stability, minimal packaging volume, a good fragrance profile .and a defined solubility profile which, above all, would guarantee high consumer satisfaction.
This problem has surprisingly been solved by a shaped body in which an ingredient (I) is mainly located in a defined region, this region being surrounded by other ingredients in exactly three directions in space.
Accordingly, the present invention relates to a shaped body containing builders, bleaching agents and surfactants, characterized in that a region containing more than 80% by weight, preferably more than 90%
by weight, more preferably more than 95% by weight and, most preferably, 100% by weight of an ingredient (I) present is surrounded by other ingredients of the shaped body in exactly three directions in space.
The ingredient (I) may be a bleaching agent from the group of chlorine and/or oxygen bleaching agents, a bleach activator, a silver protector and/or a soil-release compound, an enzyme, a surfactant or a component or a compound for controlling solubility. However, the ingredient (I) may also be a mixture of these components.
In one particularly preferred embodiment, the ingredient (I) is a mixture of a component or a compound for controlling solubility and at least one other ingredient from the group consisting of bleaching agent and/or bleach activator .and/or silver protector and/or soil-release compound and/or enzyme and/or a surfactant.
The volume of the region containing the ingredient (I), the solubility, the surface and the nature of the compression can also have a critical bearing on the properties of the tablet.
According to the invention, it can also be favorable if more than 80%
by weight, preferably more than 90% by weight, more preferably more than 95% by weight and most preferably 100% by weight of an ingredient (I) present is contained in the region of no greater than 40% by volume, preferably between 1 and 30% by volume, more preferably between 2 and 25% by volume and more preferably between 3 and 20% by volume of the shaped body.
The overall result can also be desirably influenced if the region containing more than 80% by weight, preferably more than 90% by weight, more preferably more than 95% by weight and most preferably 100% by weight of an ingredient (I) present dissolves more than 5%, preferably more than 10%, more preferably more than 25%, most preferably more than 50%
and, in one particularly advantageous embodiment, more than 100% faster than the remaining region and/or regions of the shaped body.
In another very favorable embodiment, the region containing the ingredient (I) occupies no more than 40% of the surface, preferably between 5 and 30%, more preferably between 10 and 25% and most preferably between 15 and 20% of the shaped body and more than 80% by weight, preferably more than 90% by weight, more preferably more than 95% by weight and most preferably 100% by weight of an ingredient (I) present is contained in that region.
Solubili The solubility can be influenced by components and/or compounds for accelerating solubility (disintegrators) or retarding solubility.
Suitable disintegrators are any of the disintegrators known from the prior art. Particular reference is made in this regard to Rompp (9th Edition, Vol. 6, page 4440) and Voigt "Lehrbuch der pharmazeutischen Technologie" (6th Edition, 1987). Particularly suitable disintegrators are such materials as starch, cellulose and cellulose derivatives, alginates, dextrans, crosslinked polyvinyl pyrrolidones and others; systems of weak acids and carbonate-containing disintegrators, more particularly citric acid and tartaric acid in combination with hydrogen carbonate or carbonate and polyethylene glycol sorbitan fatty acid ester.
The use of disintegrators is also known from the patent literature.
Thus, according to German patent application DE 938 566, acetyl salicylic acid is converted into granular form before compression, carefully but completely dried and then coated with highly disperse silica. The acetyl salicylic acid granules powdered with highly disperse silica may then be mixed with other tablet ingredients present in powder form or granular form and compressed to tablets. The barrier layer of highly disperse silica not only acts as an insulating layer and affords protection against unwanted reactions, it also contributes towards the rapid disintegration of the tablets, even after prolonged storage.
German patent application DE 12 28 029 describes the production of tablets in which powder mixtures are mixed with cellulose powder and optionally highly disperse silica without preliminary granulation and the resulting mixture is compressed, preferably after grinding.
According to German patent application DE 41 21 127, a particularly effective auxiliary in the production of pharmaceutical tablets comprises cellulose particles with a coating material fixed to their surface. The auxiliary is used in fine-particle form, mean particle sizes below 200 Nm being said to be particularly advantageous. Normally, therefore, traditional tablet disintegrators belonging to the first class of substances mentioned are either mixed in very fine-particle form with the other tablet ingredients, which may be present as fine-particles or granules, before the compression step or the other tablet ingredients are coated or powdered with the tablet disintegrator.
According to the teaching of European patent EP-B-0 523 099, disintegrators known from the production of pharmaceuticals may also be used in detergents or cleaning compositions. The disintegrators mentioned include swellable layered silicates, such as bentonites, starch- and cellulose-based natural materials and derivatives thereof, alginates and the like, potato starch, methyl cellulose and/or hydroxypropyl cellulose. These disintegrators may be mixed with the granules to be compressed or may even be incorporated therein.
According to International patent application WO-A-96106156 also, it can be of advantage to incorporate disintegrators in detergent tablets. In this case, too, typical disintegrators are said to include microcrystalline cellulose, sugars, such as sorbitol, and layered silicates, more particularly fine-particle and swellable layered silicates of the bentonite and smectite type. Effervescent substances, such as citric acid, bisulfate, bicarbonate, 5 carbonate and percarbonate, are also mentioned as possible disintegration aids.
European patent applications EP-A-0 466 485, EP-A-0 522 766, EP-A-0 711 827, EP-A-0 711 828 and EP-A-0 716 144 describe the production of detersive tablets in which compacted particulate material with a particle size of 180 to 2000 Nm is used. The resulting tablets may have both a homogeneous structure and a heterogeneous structure. According to EP-A-0 522 766, at least those particles which contain surfactants and builders are coated with a solution or dispersion of a binder/disintegration aid, more particularly polyethylene glycol. Other binders/disintegration aids are -again - the already repeatedly described and known disintegrators, for example starches and starch derivatives, commercially available cellulose derivatives, such as crosslinked and modified cellulose, microcrystalline cellulose fibers, crosslinked polyvinyl pyrrolidones, layered silicates, etc.
Weak acids, such as citric acid or tartaric acid which, in conjunction with carbonate-containing sources, lead to effervescent effects on contact with water and which, according to Rompp's definition, belong to the second class of disintegrators, may also be used as a coating material.
Particular reference is made to hitherto unpublished DE 197 10 254 which describes disintegrators of which the particle size distribution (sieve analysis) is such that at most 1 % by weight, preferably less, of dust is present and a total (including any dust present) of less than 10% by weight of the disintegrator granules are smaller than 0.2 mm. At least 90% by weight of the disintegrator granules advantageously have a particle size of at least 0.2 mm and at most 3 mm. These disintegrators are particularly suitable for the purposes of the present invention.
Disintegrators belonging to the group of organic acids, for example citric acid, or a citric acid/bicarbonate mixture and/or the celluloses and cellulose derivatives are also suitable. If a disintegrator is present in the shaped body, the dissolving time of the shaped body as a whole is preferably shorter than the duration of the main wash cycle of a conventional dishwashing machine, i.e. shorter than 40 rains., preferably shorter than 30 rains., more preferably shorter than 20 rains., and most preferably shorter than 10 rains.
In general, paraffins and/or microwaxes and/or the high molecular weight polyethylene glycols described in detail in the prior art are normally used as dissolution retarders. The use of mixtures mentioned in hitherto unpublished DE 197 27 073, of which the disclosure is hereby specifically included as part of the present disclosure, is particularly suitable for the purposes of the present application.
If the shaped body contains a component for retarding solubility, the dissolving time of the shaped body as a whole in cold (20°C) water - in one preferred embodiment - is longer than the prerinse cycle of a commercially available dishwashing machine, i.e. longer than 5 rains. and preferably longer than 10 rains.
General forms of presentation The shaped body may assume any of the various three-dimensional forms which are listed inter alia in patents belonging to the prior art and in the standard works of the specialist literature (for example: Riedel, "Die Tablette"). The region in which the ingredient (I) is contained is also not confined to any particular three-dimensional form. However, a dimension in one direction in space of more than 5 mm is preferred for practical reasons.
Specific forms of presentation In one preferred embodiment, the invention provides homogeneous or heterogeneous shaped bodies of known construction.

These include in particular cylindrical tablets which preferably have a diameter of 15 to 60 mm and, more particularly, 30 t 10 mm. The height of these tablets is preferably from 5 to 30 mm and more preferably from 15 to 28 mm. Shaped bodies with a diameter of 32, 33, 34, 35, 36, 37, 38 and 39 mm have proved to be particularly favorable. In particular embodiments, the height is 24, 25, 26, 27 or 28 mm.
However, aquare, rectangular, trapezoidal, oval and irregularly shaped bases may also be used with advantage. The edge lengths are preferably between 15 and 60 mm and more preferably 30 t 10 mm.
The weight of the individual shaped bodies, more particularly tablets, is preferably 15 to 60 g and more preferably 20 to 40 g per shaped body or tablet. By contrast, the density of the shaped bodies or tablets normally assumes values above 1 kg/dm3 and preferably in the range from 1.1 to 1.4 kg/dm3.
One or more shaped bodies, for example 2 to 4 shaped bodies, more particularly tablets, may be used according to the particular application, the water hardness range and the nature of the soils to be removed. Other shaped bodies according to the invention may have even smaller diameters or dimensions, for example around 10 mm.
A homogeneous shaped body in the context of the present invention is understood to be one in which the ingredients of the shaped body -except for the region containing ingredient (I) - are homogeneously distributed in such a way that differences between ingredients and/or active substances are not visible to the naked eye. The granular structure of the solids used is of course still discernible. In one preferred embodiment of the invention, only one other region (phase) is present besides the region containing the ingredient (I).
Accordingly, heterageneous shaped bodies in the context of the present invention are those in which the ingredients present besides the ingredient (I) do not have to be homogeneously distributed. In one simple case, heterogeneous shaped bodies may be produced, for example, by giving the various ingredients different colors and/or by providing them with different fragrance components.
Another case which, according to the invention, counts as a non-homogeneous (heterogeneous) shaped body is an embodiment in which a shaped body comprising several layers (phases), i.e. at least two layers, besides the region containing the ingredient (I) is compressed. For example, these various layers may have different disintegration and dissolving rates and/or may contain different ingredients. This can result in advantageous performance properties of the shaped bodies. If, for example, ingredients which adversely affect one another are present in the shaped bodies, they can be separated. If a particular sequence of cleaning conditions is to be created in a machine, one (or more) components) may be integrated in a (or the) faster disintegrating and/or faster dissolving layer while the other components) is incorporated in a (or the) more slowly dissolving layer, so that one component can act in advance or can have already reacted off by the time another component dissolves.
In one preferred embodiment of the invention, another two phases are present besides the region containing the ingredient (I): It is particularly favorable if the ratios by volume of the other two phases are between 10:1 and 1:10, preferably between 5:1 and 1:5 and more preferably between 2:1 and 1:2.
Another particularly preferred embodiment is characterized in that three or more other phases are present.
The layered structure of the shaped bodies may be stack-like, in which case the inner layers) dissolves) at the edges of the shaped body before the outer layers have completely dissolved or disintegrated.
However, the inner layers) may also be completely and/or partly surrounded by the layers situated further to the outside which prevents and/or retards the early dissolution of constituents of the inner layer(s).
In another preferred embodiment of the invention, a tablet consists of at least three layers, i.e. two outer layers and at least one inner layer, at least one of the inner layers) containing a peroxy bleaching agent whereas, in the case of the stack-like tablet, the two cover layers and - in the case of the jacket-like tablet - the outermost layers are free from peroxy bleaching agent. Peroxy bleaching agent and any bleach activators or bleach catalysts and/or enzymes present can also be separated from one another in one and the same tablet and/or shaped body. Embodiments such as these have the advantage that there is no danger of any unwanted interactions in the shaped bodies according to the invention.
In another favorable and preferred embodiment of the present invention, one of the bleach components or the bleach component, more especialty the chlorine component, is not made up in one phase with the perfume component. Another favorable and preferred embodiment of the invention is characterized in that the silver protector component is not made up with (any of) the bleach component(s). In another favorable and preferred embodiment of the invention, one of the components, or the component, for controlling solubility is made up together with the bleach activator. Another favorable and preferred embodiment of the invention is characterized in that one of the components, or the component, for controlling solubility is made up together with enzymes. Another favorable and preferred embodiment of the invention is characterized in that one of the components, or the component, for controlling solubility is made up together with the bleaching agent. Another favorable and preferred embodiment of the invention is characterized in that one of the components, or the component, for controlling solubility is made up together with the silver protector component. Another favorable and preferred embodiment of the invention is characterized in that one of the components, or the component, for controlling solubility is made up together with at least 50% by weight, preferably more than 70% by weighf and, more preferably, more than 90% by weight of a surfactant or the surfactant mixture as a whole.
The shaped bodies according to the invention are produced by any of the methods normally used for producing shaped bodies.
In some embodiments, it has proved to be particularly favorable to introduce the region containing the ingredients) (I) in the form of a liquid (quite generally a solution and/or melt), optionally at elevated temperature, 5 into a preformed recess of the surrounding ingredients and then to allow this region to solidify by applying conventional technical measures (quite generally drying and/or cooling). A viscosity of more than 1,500 mPas, preferably more than 2,000 mPas, more preferably between 2,000 and 15,000 mPas, most preferably between 2,500 and 7,000 mPas and, in a 10 particularly advantageous embodiment, between 3,000 and 4,000 mPas, has proved to be particularly effective.
It has proved to be particularly effective to combine the ingredient (I) with fusible carrier materials. These include in principle any substances which solidify at or particularly above room temperature.
According to the invention, nonionic surfactants (Dehypon~ LT 104, Dehypon~ LS 54, Dehydol~ LS 30, Lutensol~ AT 80), polyethylene glycols with various molecular weights (PEG 400, 12000), soaps (Lorol~ C 16), stearates (Cutina43~ GMS), and also thickened caustic soda and fusible salts, such as sodium carbonate decahydrate, have proved to be particularly suitable carrier materials. The advantages and disadvantages of the individual ingredients can be reproduced by the expert in tests.
The use of mixtures mentioned in hitherto unpublished DE 197 27 073, of which the disclosure is hereby specifically included as part of the present disclosure, is particularly suitable for the purposes of the present application.
In other embodiments, parts of the shaped body and/or components of the shaped body are treated by exposure to microwave radiation in order positively to influence their strength, moisture content and solubility.
However, the constituents may also be simply compressed. In this case, microtabs and shaped bodies smaller in their dimensions than the final shaped body may be used in addition to powders and granules.

Dishwasher detergents according to the invention may contain corrosion inhibitors as ingredient (I) to protect the tableware or the machine itself, silver protectors being particularly important for dishwashing machines. Known corrosion inhibitors, for example those described in DE
43 25 922, DE 41 28 672 and DE 43 38 724, may be used. Above all, silver protectors selected from the group of triazoles, benzotriazoles, bisbenzotriazoles, aminotriazoles, alkylaminotriazoles and the transition metal salts or complexes may generally be used. Benzotriazole and/or alkylaminotriazole is/are particularly preferred. In addition, dishwashing formulations often contain corrosion inhibitors containing active chlorine which are capable of distinctly reducing the corrosion of silver surfaces.

Of these, the transition metal salts selected from the group of manganese and/or cobalt salts and/or complexes are preferred, cobalt(ammine) complexes, cobalt(acetate) complexes, cobalt(carbonyl) complexes, chlorides of cobalt or manganese and manganese sulfate being particularly preferred. Zinc compounds may also be used to prevent corrosion of tableware.
Particular ingredients (I) used in accordance with the invention are substances which prevent the resoiling of surfaces and/or which facilitate the separation of soil after a single application (so-called soil-release compounds).
The soil-release compounds used in accordance with the invention include any of the compounds known from the prior art. Cationic polymers known, for example, from the following documents are particularly suitable:
5 According to EP-A-0 167 382, EP-A-0 342 997 and DE-OS 26 16 404, cationic polymers are added to cleaning compositions to obtain streak-free cleaning of the surfaces.
EP-A-0 167 382 describes liquid cleaning compositions which may contain cationic polymers as thickeners. Hydroxypropyl trimethyl ammoni-10 um guar; copolymers of aminoethyl methacrylate and acrylamide and copolymers of dimethyl diallyl ammonium chloride and acrylamide are described as particularly suitable cationic polymers.
EP-A-0 342 997 describes multipurpose cleaners which may contain cationic polymers" polymers containing imino groups in particular being 15 used.
DE-OS 26 16 404 describes cleaning compositions for glass containing cationic cellulose derivatives. The addition the cationic cellulose derivatives to the compositions ensures better drainage of the water so that streak-free glass is obtained.
EP-A-0 467 472, for example, describes cleaning compositions for hard surfaces which contain cationic homopolymers and/or copolymers as soil-release polymers. These polymers contain quaternized ammonium alkyl methacrylate groups as monomer units. These compounds are used to finish the surfaces in such a way that the soils can be removed more easily the next time the surfaces are cleaned.
Particular preference is attributed to the cationic polymers selected from cationic polymers of copolymers of such monomers as trialkyl am-monium alkyl (meth)acrylate or acrylamide; dialkyl diallyl diammonium salts; polymer-analog reaction products of ethers or esters of poly-saccharides with lateral ammonium groups, more particularly guar, cel-lulose and starch derivatives; polyadducts of ethylene oxide with ammon-ium groups; quaternary ethylene imine polymers and polyesters and poly-amides containing quaternary lateral groups as soil-release compounds.
Natural palyuronic acids and related substances and also polyampholytes and hydrophobicized polyampholytes and mixtures of these substances are also particularly preferred for the purposes of the present invention.
According to the invention, between 0 and 5% by weight of enzymes, based on the composition as a whole, may be added to the detergent/cleaner to improve performance or guarantee the same quality of cleaning under milder conditions. The most commonly used enzymes include lipases, amylases, cellulases and proteases. Preferred proteases are, for example, BLAP~ 140 (Biozym), Optimase~ M-440 and Opticlean~
M-250 (Solvay Enzymes); Maxacal~ CX and Maxapem~ or Esperase~
(Gist Brocades) and even Savinase~ (Novo). Particularly suitable celluloses and lipases are Celluzym~ 0,7 T and Lipolase~ 30 T (Novo Nordisk). Particularly suitable amylases are Duramyl~ and Termamyl~ 60 T and Termamyl~ 90 T (Novo), Amylase-LT~ (Solvay Enzymes) and Maxamyl~ P5000 (Gist Brocades). Other enzymes may also be used.
Other ingredients In the shaped bodies according to the invention, all ingredients (I) described above can also perform the function of other ingredients should the condition of the region according to the invention be fulfilled by other ingredients.
Water-soluble and water-insoluble builders may be used in the detergents/cleaners according to the invention, above all to bind calcium and magnesium. Water-soluble builders are preferred because, in general, they tend less to form insoluble residues on tableware and hard surfaces.
Typical builders which may be present in quantities of 10 to 90% by weight, based on the composition as a whole, in accordance with the invention are the low molecular weight polycarboxylic acids and salts thereof, the homo-polymeric and copolymeric polycarboxylic acids and salts thereof, the car-bonates, phosphates and silicates. Water-insoluble builders include the zeolites, which may also be used, and mixtures of the builders mentioned above.
Trisodium citrate and/or pentasodium tripolyphosphate and/or sodium carbonate and/or sodium bicarbonate and/or gluconates and/or silicate builders from the class of disilicates and/or metasilicates are preferably used.
Alkali sources may be present as further ingredients. Alkali sources are alkali metal hydroxides, alkali metal carbonates, alkali metal hydrogen carbonates, alkali metal sesquicarbonates, alkali metal silicates, alkali metal metasilicates and mixtures of the substances mentioned above.
According to the invention, alkali metal carbonates, more particularly sodium carbonate, sodium hydrogen carbonate or sodium sesqui carbonate, are preferably used.
A builder system containing a mixture of tripolyphosphate and sodium carbonate is particularly preferred.
Another particularly preferred builder system contains a mixture of tripolyphosphate and sodium carbonate and sodium disilicate.
In principle, any surfactants may be used as surfactants. Nonionic surfactants, above all low-foaming nonionic surfactants, are preferred although other low-foaming surfactants may also be used. Alkoxylated alcohols, especially ethoxylated and/or propoxylated alcohols, alkyl polyglycosides, and alkyl polyglucamides are particularly preferred.
Alkoxylated alcohols are generally understood by the expert to be the reaction products of alkylene oxide, preferably ethylene oxide, with alcohols, the relatively long-chain alcohols (C~o to C~8, preferably between C~2 and C~6 such as, for example, C», C,2, C~3, C~4, C~5, C,6, C~~ and C,8 alcohols) being preferred for the purposes of the present invention. In general, a complex mixture of addition products differing in their degree of ethoxylation is formed from n moles of ethylene oxide and 1 mole of alcohol, depending on the reaction conditions. Another embodiment is characterized by the use of mixtures of alkylene oxides, preferably a mixture of ethylene oxide and propylene oxide. If desired, "end-capped"
alcohol ethoxylates, which may also be used in accordance with the invention, may also be obtained by etherification with short-chain alkyl groups, preferably butyl groups, in a concluding step. According to the invention, highly ethoxylated fatty alcohols or mixtures thereof with end-capped fatty alcohol ethoxylates are particularly preferred for the purposes of the invention.
Alkyl polyglycosides are surfactants which may be obtained by reacting sugars and alcohols using the relevant methods of preparative organic chemistry, a mixture of monoalkylated oligomeric or polymeric sugars being obtained according to the particular method of production used. Preferred alkyl polyglycosides are alkyl polyglucosides. In a particularly preferred embodiment, the alcohol is a long-chain fatty alcohol or a mixture of long-chain fatty alcohols while the degree of oligomerization of the sugars is between 1 and 10.
Fatty acid polyhydroxylamides (glucamides) are acylated reaction products of the reductive amination of a sugar (glucose) with ammonia, long-chain fatty acids, long-chain fatty acid esters or long-chain fatty acid chlorides generally being used as acylating agents. Secondary amides are formed if methyl amine or ethyl amine is used instead of ammonia for the reduction process, as described for example in SOFW Journal, 119, (1993), 794-808. Carbon chain lengths of Cs to C~2 are preferably used in the fatty acid moiety.

Each of the formulations may of course also contain other ingredients typical of MDWM (for example fillers, preservatives and the like) in extremely small quantities, in which case the percentage contents of the other ingredients should be varied accordingly.
The production of the shaped bodies according to the invention involves steps which are known to the expert in this field in another connection. A preferred embodiment of the shaped body according to claim 1 contains a recess in a tablet, this recess containing the ingredient (I). Production is preferably carried out by forming a depression in a shaped body and filling the depression thus formed. The depression may be formed in a Korsch rotary press. In the present case, a Fette tablet press was used. A round tablet die (26 x 36 mm) was selected and, using a punch, a 5 mm deep recess was formed in one side, the base of the recess being selected so that a volume of 1 ml could be poured in, the surface of the tablet thereafter becoming smooth again.
A liquid mixture of paraffin and an active substance (I) was then poured in and allawed to cool. The cooling process may be assisted by conventional methods and equipment.
As already mentioned, the ingredient (I) was quantitatively reduced beforehand in accordance with the invention in the corresponding formulation surrounding the filled region and, in the present Examples and studies, was left out in the surrounding regions.
In comparisons with homogeneous tablets (where ingredient (I) does not correspond to the invention) and a few commercially available tablets, the tablets according to the invention proved to be superior.
The particular properties of the detergents/cleaners according to the invention were tested by comparison with known detergents/cleaners using storage stability as an example. The particular properties of the detergents/cleaners according to the invention were tested in comparison with known detergents/cleaners using the removal of tea stains as an example. The particular properties of the detergents/cleaners according to the invention were tested by comparison with known detergents/cleaners using the removal of enzyme-relevant stains as an example.
In addition, the particular properties of the detergents/cleaners according to the invention were tested by technically untrained people under simulated practical conditions in comparison with homogeneous tablets. Apart from dosing instructions and general safety instructions, the handling of the detergents/cleaners by the people in question in commercially available dishwashing machines was not influenced in any way. This comparison test produced particularly good results. The cleaning results were evaluated as particularly favorable.
Particularly good results were obtained when a soil release compound was used as ingredient (I). In a mixture corresponding to formulation Ra or Va1, up to 2% by weight of polyuronic acids, cationic polymers and hydrophobicized polyampholytes were used independently of one another, builder being omitted. The cleaning performance against milk and starch-containing soils in a following wash cycle was between 10 and 30% better than in the case of untreated samples.
In another 'washing test, samples according to starting formulation Ra which contains active chlorine (dichlorocyanurate) as bleaching component on the one hand in homogeneous distribution in the tablet and, on the other hand, in accordance with claim 1, so that the active chlorine was largely separated from the other (particularly enzyme-containing) components, were used. Storage stability after 2 weeks was distinctly poorer in the case of the homogeneous tablet so it was not possible to obtain a satisfactory cleaning effect against milk and starch-relevant stains.
This applies to the entirely normal making-up of the bleach component in region (I) which, in the present case, represented a recess. The effect is even clearer where a mixture of chlorine component and paraffin is used in a standard program at 55°C. The cleaning results were better even immediately after production. The effect improved with storage. Tea, milk, burnt-on meat, burnt-in meat, egg and starch mixtures in particular were removed far more effectively than by tablets without a region (I), i.e. with a homogeneously distributed component (I), and commercially available dishwasher tablets.
The effect was discernible even with paraffins having a melting point of 40 to 44°C. The effect is more pronounced with paraffins having a melting point of 46 to 48°C. The cleaning effect is particularly pronounced with paraffins having a melting point of 57 to 60°C.
In another washing test, samples (according to Ra) containing small quantities of metal catalysts (Mn catalyst, cobalt catalyst (cobalt-pentammine-chloro complex) and, in one case, n-methyl morpholinium acetonitrile methyl sulfate (MMA) as bleach activator component on the one hand in homogeneous distribution in the tablet and on the other hand in accordance with claim 1, so that the activator component was largely separated from other components (particularly enzyme-containing components), were used. The storage stability after 2 weeks was distinctly poorer in the case of the homogeneous tablet, so that the cleaning effect against milk and starch-relevant stains was far from satisfactory.
This applies to the entirely normal making-up of the bleach activator component in region (I) which, in the present case, represented a recess.
The effect is even clearer where a mixture of activator component and paraffin is used in a standard program at 55°C. The cleaning results were better even immediately after production. The effect improved with storage. Improvements in the removal of tea stains in particular were obtained and milk, burnt-on meat, burnt-in meat, egg and starch mixtures were also removed more effectively than by tablets without a region (I), i.e.
with a homogeneously distributed component (I), and commercially available dishwasher tablets.
The effect was even discernible with paraffins having a melting point of 40 to 44°C. The effect was more pronounced with paraffins having a melting point of 4C to 48°C. The cleaning effect is also clearly discernible with paraffins having a melting point of 57 to 60°C.
In another test, samples containing surfactants on the one hand in homogeneous distribution in the tablet and, on the other hand, in accordance with claim 1, so that the surfactant component was largely separated from other components, were used. In this case, the final rinse results were evaluated. Where a mixture of surfactant and paraffin was used in a standard program at 55°C, the results obtained were better than those obtained with tablets without a region (I), i.e with a homogeneously distributed component (I), and commercially available dishwasher tablets.

The results clearly show that the tablets according to the invention are superior to conventional dishwasher tablets.
