Detergents or cleaning agents are usually in solid form (for example as tablets) or in liquid form (or also as a flowing gel). In particular, liquid detergents or cleaning agents are enjoying increasing popularity with consumers. Pre-portioned forms of presentation are popular with consumers because they are easier to dose. In this context, pre-portioned flowing gels are often problematic because they tend to leak, for example when packaged in single-chamber or multi-chamber bags.

The haptics and optics that can be experienced during use also play a role and may decide on dissatisfaction or renewed incentive to buy.

The object of the present invention is to provide detergents or cleaning agents, in particular dishwashing detergents, preferably machine dishwashing detergents, which can be produced even more simply and cost-effectively and at the same time have an appealing feel and appearance.

enthält.A first subject matter of the present invention thus relates to detergents or cleaning agents, preferably dishwashing agents, in particular machine dishwashing agents, comprising a gel, preferably a gel which is solid at room temperature (20° C.), which, based on the total weight of the gel,

1. a) 10 to 20% by weight, preferably 12 to 18% by weight, in particular 12.7 to 15.5% by weight, of PVOH and/or derivatives thereof,

According to the invention, a gel or a gel-like phase, also referred to below as a gel phase, means a composition (or phase) which has an internally structuring network. This internal structuring (spatial) network is formed by the dispersion of a solid but distributed substance with long or highly branched particles and/or gelling agent, here polyvinyl alcohol and/or its derivatives, in at least one liquid (the at least one liquid is liquid at 20° C) formed. Such gel phases behave thermoreversibly.

The washing or cleaning agent can have one, two, three, four or more gels or gel phases. The gels/gel phases can be the same or different. In the case of several gels or gel phases, these can preferably be distinguished spatially, optically and/or on the basis of their ingredients. If the gels/gel phases are different, they can preferably have different dyes and different additions of active substances.

The gel is dimensionally stable. During production, the polyvinyl alcohol and/or its derivatives are brought into contact with glycerol. This gives a flowable mixture which can be brought into a desired shape. After a certain period of time, a gel/a gel phase is obtained which remains in the specified form, i.e. is dimensionally stable. This period of time, the setting time, is preferably 15 minutes or less, preferably 10 minutes or less, particularly preferably 5 minutes or less. The gel gives way under pressure, but does not deform as a result, but returns to its original state after the pressure is removed. The gel is preferably elastic, in particular linear-elastic.

The gel is preferably a shaped body. A molded body is a single body that stabilizes itself in its imposed shape. This dimensionally stable body is formed from a molding compound (e.g. a composition) by bringing this molding compound into a predetermined shape in a targeted manner, e.g. by pouring a liquid composition into a mold and then curing the liquid composition, e.g. as part of a sol-gel process.

Certain minimum requirements are placed on formulations of the at least one gel phase. As already stated, the gel must solidify within the shortest possible time. Long solidification times would lead to a long production time and thus to high costs. According to the invention, the setting time means the period of time during which the gel changes from a flowable to a non-flowable, dimensionally stable state at room temperature during production. Room temperature is understood to mean a temperature of 20°C.

The gel is a solid gel phase. It is preferably cut-resistant. It can, for example, be cut with a knife after it has solidified without being destroyed further, except at the point where the cut was made.

A phase within the meaning of the present invention is a spatial area in which physical parameters and the chemical composition are homogeneous. A phase differs from another phase by various features, for example ingredients, physical properties, external appearance, etc. Various phases can preferably be distinguished visually. Thus, the at least one solid phase can be clearly distinguished from the at least one gel phase for the consumer. If the washing or cleaning agent according to the invention has more than one solid phase, these can also be distinguished from one another with the naked eye because they differ from one another, for example in terms of color. The same applies if two or more gel phases are present. In this case, too, an optical differentiation of the phases is possible, for example on the basis of a difference in color or transparency. Phases within the meaning of the present invention are therefore self-contained areas which the consumer can visually distinguish from one another with the naked eye. The individual phases can have different properties when used, such as the speed with which the phase dissolves in water and thus the speed and sequence of release of the ingredients contained in the respective phase.

In addition, the gel is preferably translucent (translucent) or transparent, which results in a good optical impression. The transmittance of the gel phase (without dye) is preferably in a range between 100% and 20%, between 100% and 30%, in particular between 100% and 40%. To measure the light transmittance (transmission), the permeability was determined in % at 600 nm against water as a reference at 20 °C. For this purpose, the mass was poured into the 11 mm round cuvettes provided and, after a storage time of 12 h at room temperature, measured in a LICO 300 color measuring system according to Lange.

The detergents or cleaning agents according to the invention, preferably dishwashing detergents, in particular machine dishwashing detergents, contain polyvinyl alcohol and/or polyvinyl alcohol Derivatives in an amount of 10 to 20% by weight, in particular 12 to 18% by weight, particularly preferably in an amount of 12.7 to 14.6% by weight, based in each case on the total weight of the gel.

Polyvinyl alcohols are thermoplastics that are usually produced as a white to yellowish powder by the hydrolysis of polyvinyl acetate. Partially hydrolyzed polyvinyl alcohol which still has amounts of up to 30 mol % of non-hydrolyzed acetyl groups is to be understood as polyvinyl alcohol in the context of the invention. Polyvinyl alcohol (PVOH) is resistant to almost all anhydrous organic solvents. Polyvinyl alcohols with a molar mass of 30,000 to 60,000 g/mol are preferred.

According to a preferred embodiment, the gel comprises PVOH (polyvinyl alcohol). The gels or gel phases produced in this way have a particularly high melting point, are dimensionally stable (even at 40° C.) and do not change their shape, if at all, only insignificantly, even during storage. In particular, they are also not very reactive with regard to a direct negative interaction with components of a granular mixture, in particular an additional powder phase. In particular, PVOH can produce low-water or water-free gel phases. When using PVOH as a polymer for the gel, low-viscosity melts are produced at 110-120 °C, which are particularly easy to process. In particular, the gel phase can be filled into the water-soluble coating quickly and precisely without sticking or the amount is dosed imprecisely. Furthermore, these gel phases adhere particularly well to the water-soluble coating, in particular if this is also made from PVOH. This is also a visual advantage. Due to the rapid solidification of the at least one gel phase with PVOH, the further processing of the gel phases can take place particularly quickly. Furthermore, the good solubility of the gel phases produced is particularly favorable for the overall solubility of the washing or cleaning agent. In addition, gel phases with such short solidification times are advantageous so that the at least one solid phase metered thereon, comprising granular mixtures, in particular powder, does not sink into the gel that is not yet completely solidified or is too soft. This leads to visually unappealing washing or cleaning agent portions.

Particular preference is given to polyvinyl alcohols, which are available as white-yellowish powders or granules with degrees of polymerization in the range from about 100 to 2500 (molar masses from about 4000 to 100,000 g/mol) and degrees of hydrolysis from 80 to 99 mol%, preferably from 85 to 90 mol %, in particular from 87 to 89 mol%, for example 88 mol%, which accordingly still contain a residual content of acetyl groups.

PVOH powders with the properties mentioned above, which are suitable for use in the at least one gel phase, are marketed, for example, by Kuraray under the name ^Mowiol® or ^Poval® . Also suitable, for example, is ^Exceval® AQ4104 from Kuraray. Particularly suitable are Mowiol C30, the Poval ^® qualities, in particular the qualities 3-83, 3-88, 6-88, 4-85, and particularly preferably 4-88, very particularly preferably Poval 4-88 S2 and Mowiol ^® 4- 88 by Kuraray.

According to the invention, preferred derivatives of PVOH are copolymers of polyvinyl alcohol with other monomers, in particular copolymers with anionic monomers. Suitable anionic monomers are preferably vinylacetic acid, alkyl acrylates, maleic acid and derivatives thereof, in particular monoalkyl maleates (especially monomethyl maleate), dialkyl maleates (especially dimethyl maleate), maleic anhydride, fumaric acid and derivatives thereof, in particular monoalkyl fumarate (especially monomethyl fumarate), dialkyl fumarate (especially dimethyl fumarate), fumaric anhydride, Itaconic acid and its derivatives, in particular monomethyl itaconate, dialkyl itaconate, dimethyl itaconate, itaconic anhydride, citraconic acid (methylmaleic acid) and its derivatives, monoalkyl citraconic acid (especially methyl citraconic acid), dialkyl citraconic acid (dimethyl citraconic acid), citraconic acid anhydride, mesaconic acid (methyl fumaric acid) and its derivatives, monoalkyl mesaconate, dialkyl mesaconate, mesaconic acid anhydride, glutaconic acid and their derivatives, monoalkyl glutaconate, dialkyl glutaconate, glutaconic anhydride, vinyl sulfonic acid, alkyl sulfonic acid, ethylene sulfonic acid, 2-acrylamido-1-methylpropane sulfone acid, 2-acrylamido-2-methylpropanesulfonic acid, 2-methylacrylamido-2-methylpropanesulfonic acid, 2-sulfoethyl acrylate and combinations thereof, and the alkali metal salts or esters of the abovementioned monomers.

Particularly preferred derivatives of PVOH are those selected from copolymers of polyvinyl alcohol with a monomer selected in particular from the group of monoalkyl maleates (especially monomethyl maleate), dialkyl maleates (especially dimethyl maleate), maleic anhydride, and combinations thereof, and the alkali metal salts or esters of the above mentioned monomers. The values given for the polyvinyl alcohols themselves apply to the suitable molar masses. In the context of the present invention, it is preferred that the gel comprises a polyvinyl alcohol and/or derivatives thereof, preferably polyvinyl alcohol, the degree of hydrolysis of which is preferably 70 to 100 mol %, in particular 80 to 90 mol %, particularly preferably 81 to 89 mol %. % and especially 82 to 88 mol%.

The water solubility of polyvinyl alcohol can be changed by post-treatment with aldehydes (acetalization) or ketones (ketalization). These are also to be understood as derivatives of polyvinyl alcohol. Polyvinyl alcohols which are acetalized or ketalized with the aldehyde or keto groups of saccharides or polysaccharides or mixtures thereof have proven to be particularly preferred and particularly advantageous due to their extremely good solubility in cold water. The reaction products of polyvinyl alcohol and starch can be used extremely advantageously. Furthermore, the water solubility by complexing with Ni or Cu salts or by treatment with dichromates, boric acid, borax and thus adjust to desired values.

The detergents or cleaning agents, preferably dishwashing detergents, in particular machine dishwashing detergents, in the gel/gel phase contain 27.0 to 35.0% by weight of 1,3-propanediol, preferably 30.5 to 33.0% by weight of 1, 3-propanediol, particularly preferably 31.0 to 32.0% by weight of 1,3-propanediol, very particularly preferably 1,3-propanediol, based on the total weight of the gel.

According to the invention, the gel phase contains at least one polyalkylene glycol. According to the invention, copolymers of ethylene oxide and propylene oxide are not included among the polyalkylene glycols. The gel preferably contains at least one polyethylene glycol and/or at least one polypropylene glycol and mixtures thereof.

The gel contains 12 to 18.5% by weight, preferably 13.5 to 16.5% by weight, of at least one polyalkylene glycol, based on the total weight of the gel. In particular, polyethylene glycol and/or polypropylene glycol and mixtures thereof are preferred as the polyalkylene glycol. Polyethylene glycols with an average molar mass of between about 100 and 8000 are particularly suitable here.

The polyalkylene glycols used are preferably liquid at 20° C. and 1 bar. According to the invention, polyethylene glycol(s) with an average molar mass of 200 to 600 g/mol are therefore preferably additionally used in the at least one gel phase or the gel phases. In this case, in combination with polyvinyl alcohol, polyethylene glycols with an average molar mass of between about 200 and about 600 g/mol, preferably between 300 and 500 g/mol, particularly preferably between 350 and 450 g/mol, for example around 400 g/mol INCI: PEG400) deployed. Washing or cleaning agent portions according to the invention are thus characterized in that they contain polyethylene glycol(s) with an average molar mass of 300 to 500 g/mol, in particular 350 to 450 g/mol.

Surprisingly, it has been shown that the addition of polyethylene glycols, in particular those with an average molar mass of 200 to 600 g/mol, to the at least one gel phase, in particular in the case of gel phases comprising polyvinyl alcohol, accelerates the solidification time of the gel phases. Values of a few minutes and even less than a minute can be achieved. This is of great advantage in particular for the production processes, since the further processing of the gel phases in the solidified state can be carried out much more quickly and therefore generally more cost-effectively. Surprisingly, it was found that the presence of polyethylene glycol(s) with an average molar mass of 200 to 600 g/mol in combination with polyvinyl alcohol and/or its derivatives makes a decisive contribution to reducing the solidification times to less than 1 min, preferably less than 50 seconds, in particular preferably to reduce below 40 seconds. Without being bound to theory, it is assumed that such polyethylene glycols, in particular those with a molar mass of 350 to 450 g/mol, increase the sol-gel temperature, in particular by 400 g/mol.

In a particularly preferred embodiment, component d) is polyethylene glycols, preferably polyethylene glycol(s) with an average molecular weight of 200 to 600, in particular 350 to 450 g/mol, for example around 400 g/mol, in an amount of 13.5 to -16.5% by weight.

According to a further embodiment, in addition to the polyethylene glycols mentioned with an average molecular weight of 200 to 600 g/mol, further polyalkylene glycols, in particular further polyethylene glycols, with an average molecular weight between about 800 and 8000 can be contained in the at least one gel phase. These polyethylene glycols are particularly preferably used in amounts of 1 to 10% by weight, preferably 2 to 5% by weight, preferably based in each case on the total weight of the gel.

The gel also comprises, as component c), 23-29.5% by weight of glycerol, based on the total weight of the gel. Glycerin is particularly preferably contained in the gel in an amount of 25-28% by weight, based on the total weight of the gel.

The gel is essentially anhydrous. This means that the gel is preferably essentially free of water. "Essentially free" here means that small amounts of water can be contained in the gel phase. This water can be introduced into the phase, for example, by a solvent or as water of crystallization or as a result of reactions of components of the phase with one another. However, preferably only small amounts, in particular no water, are used as the solvent for the production of the gel phase. In this embodiment, the proportion of water in the gel phase is <5% by weight water, preferably 4.9% by weight or less, 4% by weight or less, preferably 2% by weight or less, in particular 1% by weight % or less, preferably <1% by weight, in particular 0.5% by weight or less, in particular 0.1% by weight or 0.05% by weight or less. The percentages by weight relate to the total weight of the gel.

These compositions exhibit particularly good fluidity during dosing and, at the same time, an advantageously short setting time after dosing the gel and cooling, while at the same time exhibiting only low syneresis. This means that no large amounts of liquid ingredients escape from the gel. The visible leakage of liquid from the gel ("sweating") means that the gel is no longer so easy to handle. The consumer sees this as unaesthetic as well as a qualitative defect. Depending on how the gel is sold, sweating also means difficulties in handling the gel safely.

The escape of liquid from the gel is to be avoided as far as possible, since interactions between the liquid and any ingredients contained in a further phase and/or a water-soluble coating occur in washing or cleaning agent portions. This leads to aesthetically undesirable discolorations or to the inactivation of sensitive ingredients, to the dissolution or softening of encapsulations, e.g. coatings or the water-soluble encapsulation.

In particular, less than 5 wt temperature of 20 °C.

These and other aspects, features and advantages of the invention will become apparent to those skilled in the art from a study of the following detailed description and claims. Each feature from one aspect of the invention can be used in any other aspect of the invention. Furthermore, it should be understood that the examples contained herein are intended to describe and illustrate the invention, but not to limit it, and in particular the invention is not limited to these examples. All percentages are % by weight unless otherwise stated. Numerical ranges given in the format "from x to y" include the stated values. Where multiple preferred numeric ranges are given in this format, it is understood that any ranges resulting from the combination of the different endpoints are also included.

"At least one" as used herein means 1 or more, i.e. 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. With regard to an ingredient, the information refers to the type of ingredient and not to the absolute number of molecules. "At least one bleach catalyst" thus means, for example, at least one type of bleach catalyst, i.e. it can mean one type of bleach catalyst or a mixture of several different bleach catalysts. Together with weight information, the information refers to all compounds of the type specified that are contained in the composition/mixture, i.e. the composition does not contain any other compounds of this type beyond the specified amount of the corresponding compounds.

When reference is made herein to molar masses, this information always relates to the number-average molar mass M _n , unless explicitly stated otherwise. The number average molar mass can be determined, for example, by means of gel permeation chromatography (GPC) in accordance with DIN 55672-1:2007-08 with THF as the eluent. The mass-average molar mass M _w can also be determined by GPC, as described for M _n .

Unless explicitly stated otherwise, all percentages given in connection with the compositions described herein relate to % by weight, in each case based on the mixture or phase in question.

Furthermore, the gel must be storage-stable under normal storage conditions. The gel phase according to the invention is part of a washing or cleaning agent. Detergents or cleaning agents are usually stored in a household for a certain period of time. They are usually stored near the washing machine or dishwasher. For such storage, the gel should be stable. Thus, the gel should in particular after a storage time of, for example, 4 to 12 weeks, in particular 10 to 12 weeks or longer at a Temperature of up to 40 °C, especially at 30 °C, in particular at 25 °C or at 20 °C and not deform during this time or otherwise change in consistency.

If the gel and a solid, in particular a powder phase are in direct contact with one another, the gel penetrates into the interstices of the immediately underlying powder phase by a maximum of 1 mm during the storage period of 4 weeks at 25°C.

A change in volume or shrinkage during storage would be disadvantageous, since this would result in poor acceptance of the product by consumers. Escape of liquid or exudation of components from the gel phase is also undesirable. On the one hand, the visual impression is also relevant here. The stability of the gel phase can be influenced by the emergence of liquid, such as solvents, so that the components are no longer contained in a stable manner and the washing or cleaning effect can thereby also be influenced.

The zinc salt to be used with preference according to the invention is water-soluble, which means that it has a solubility in water of more than 100 mg/l, preferably more than 500 mg/l, particularly preferably more than 1 g/l and in particular more than 5 g/l (all solubilities at 20° C water temperature). The inorganic zinc salt is preferably selected from the group consisting of zinc bromide, zinc chloride, zinc iodide, zinc nitrate and zinc sulfate. The organic zinc salt is preferably selected from the group consisting of zinc salts of monomeric or polymeric organic acids, in particular from the group of zinc acetate, zinc acetylacetonate, zinc PCA (zinc 5-oxopyrrolidine-2-carboxylate), zinc benzoate, zinc chloride, zinc formate, zinc lactate, zinc gluconate, zinc ricinoleate , zinc abietate, zinc valerate and zinc p-toluenesulfonate.

In a particularly preferred embodiment according to the invention, the water-soluble zinc salt used is zinc chloride, zinc acetate or zinc sulfate, in particular anhydrous zinc salt (anhydrate), particularly preferably zinc acetate (anhydrate).

The zinc salt is present in the gel phase preferably in an amount of from 0.05% to 3% by weight, more preferably in an amount of from 0.1% to 2.4% by weight, especially in a Amount from 0.2% to 1.0% by weight, based on the total weight of the gel phase.

Zinc salts can also be contained in a solid phase that may be present, preferably a particulate phase, or in granular mixtures. In this case, the zinc salt in agents according to the invention is preferably in an amount of 0.01% by weight to 5% by weight, particularly preferably in an amount of 0.05% by weight to 3% by weight, in particular in a lot from 0.1% by weight to 2% by weight, based on the total weight of the detergent or cleaning agent.

In addition to the effect of such zinc salts as glass corrosion inhibitors, it was surprisingly found that the presence of zinc salts in the gel phase contributes to stabilizing the gel and improving processability. It is found to be particularly disadvantageous if the gel can no longer be processed within a short time after production. If the gel becomes too viscous within a short time after production, it can no longer be dosed in the usual way. Furthermore, yellowing of the gel is also frequently observed, which is visually displeasing to the end user and causes the latter to perceive the product as "no longer fresh" or "no longer usable". For the production process, this means that the gel only has to be freshly prepared in small quantities and at short time intervals in order to ensure that the gel can still be filled into the product. In particular, the time window in which the gel can be processed (service life) is significantly extended by the addition of the zinc salt.

Detergents or cleaning agents, preferably dishwashing detergents, in particular machine dishwashing detergents, particularly preferably contain at least one water-soluble zinc salt, in particular zinc sulfate and/or zinc acetate, in particular zinc acetate, in an amount of from 0.05 to 5% by weight, in particular from 0.1 to 2 0.0% by weight, most preferably from 0.2 to 1.0% by weight, based on the total weight of the gel.

According to a further preferred embodiment of the present invention, detergents or cleaning agents, preferably dishwashing detergents, in particular automatic dishwashing detergents, which are packaged as washing or cleaning agent portions, which preferably contain the active ingredients required for a cleaning cycle, contain the total amount of the water-soluble zinc salts, in particular zinc sulfate and /or zinc acetate, in particular zinc acetate, in the detergent or cleaning agent portion, preferably 0.0004 to 0.5 g, preferably 0.001 to 0.2 g, in particular 0.02 to 0.06 g.

This means that the individual detergent or cleaning agent portion, which is used to carry out an individual cleaning cycle, in particular in a cleaning cycle of an automatic dishwasher, is added in total 0.0005 to 1 g, preferably 0.01 to 0.5 g, in particular 0 0.02 to 0.06 g of water-soluble zinc salts, in particular zinc sulfate and/or zinc acetate, in particular zinc acetate.

According to a further particularly preferred embodiment, the washing or cleaning agent, preferably dishwashing agent, in particular machine dishwashing agent, is a washing or cleaning agent portion in a water-soluble envelope with one or more chambers/compartments. The washing or cleaning agent is preferably packaged as a single portion of cleaning agent, so that it is used to run through a dishwasher and is (largely) essentially consumed in the process.

The water-soluble cover is preferably formed from a water-soluble film material which is selected from the group consisting of polymers or polymer mixtures. The cover can be formed from one or from two or more layers of the water-soluble film material. The water-soluble film material of the first layer and the further layers, if any, can be the same or different.

It is preferred that the water-soluble coating contains polyvinyl alcohol or a polyvinyl alcohol copolymer. Water-soluble coatings that contain polyvinyl alcohol or a polyvinyl alcohol copolymer have good stability with sufficiently high water solubility, especially cold water solubility.

Suitable water-soluble films for producing the water-soluble envelope are preferably based on a polyvinyl alcohol or a polyvinyl alcohol copolymer whose molecular weight is in 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 .

Polyvinyl alcohol is usually produced by hydrolysis of polyvinyl acetate, since the direct synthesis route is not possible. The same applies to polyvinyl alcohol copolymers which are correspondingly produced from polyvinyl acetate copolymers. It is preferred if at least one layer of the water-soluble coating comprises a polyvinyl alcohol whose degree of hydrolysis is 70 to 100 mol %, preferably 80 to 90 mol %, particularly preferably 81 to 89 mol % and in particular 82 to 88 mol %.

In a preferred embodiment, the water-soluble packaging consists of at least 20% by weight, more preferably at least 40% by weight, very preferably at least 60% by weight and in particular at least 80% by weight of a polyvinyl alcohol whose Degree of hydrolysis is 70 to 100 mol%, preferably 80 to 90 mol%, particularly preferably 81 to 89 mol% and in particular 82 to 88 mol%.

A polyvinyl alcohol-containing film material suitable for producing the water-soluble casing can also have a polymer selected from the group consisting of (meth)acrylic acid-containing (co)polymers, polyacrylamides, oxazoline polymers, polystyrene sulfonates, polyurethanes, polyesters, polyethers, polylactic acid or mixtures of the above Polymers can be added. A preferred additional polymer are polylactic acids.

In addition to vinyl alcohol, preferred polyvinyl alcohol copolymers include dicarboxylic acids as further monomers. Suitable dicarboxylic acids are itaconic acid, malonic acid, succinic acid and mixtures thereof, with itaconic acid being preferred. Polyvinyl alcohol copolymers which are also preferred include, in addition to vinyl alcohol, an ethylenically unsaturated carboxylic acid, its salt or its ester. Such polyvinyl alcohol copolymers particularly preferably contain, in addition to vinyl alcohol, acrylic acid, methacrylic acid, acrylic acid esters, methacrylic acid esters or mixtures thereof.

It can be preferred that the film material contains other additives. The film material can contain, for example, plasticizers such as dipropylene glycol, ethylene glycol, diethylene glycol, propylene glycol, glycerol, sorbitol, mannitol or mixtures thereof. Further additives include, for example, release aids, fillers, crosslinking agents, surfactants, antioxidants, UV absorbers, anti-blocking agents, anti-adhesive agents or mixtures thereof.

Suitable water-soluble films for use in the water-soluble wrappers of the water-soluble packaging according to the invention are films available from MonoSol LLC, for example under the designation M8720, M8630, M8312, M8440, M7062, C8400 or M8900 to be expelled. Films sold by Nippon Gohsei under the designation SH2601, SH2504, SH2707 or SH2701 are also suitable. Other suitable films include ^Solublon® PT, ^Solublon® GA, ^Solublon® KC or ^Solublon® KL films from Aicello Chemical Europe GmbH or Kuraray VF-HP films.

In particular, the outer surface of the water-soluble casing is at least partially coated with a bitter substance having a bitterness value between 1,000 and 200,000. In this context, it is particularly preferable that the water-soluble casing is coated to at least 50%, preferably at least 75% and most preferably at least 90% with the bitter substance having a bitterness value between 1,000 and 200,000. The application of the bitter substance with a bitter value between 1,000 and 200,000 can be done, for example, by printing, spraying or brushing.

According to the invention, the water-soluble casing preferably has at least one continuous circumferential sealing seam, which essentially lies in one plane. This is favorable in terms of process technology, since only a single sealing step, possibly using only a single sealing tool, is necessary for a circumferential sealing seam which lies essentially in one plane. The continuously circumferential sealing seam leads to a better closure compared to such casings with several sealing seams and an excellent tightness of the sealing seam and thus of the casing itself. Leaking of product from the casing, e.g. on the surface of the portion would be disadvantageous, since the consumer would then be exposed to the product came into contact. However, this is precisely what should be avoided as far as possible in the case of a detergent or cleaning agent portion with a water-soluble coating.

The water-soluble casing can preferably be made from at least 2 packaging parts. The at least two packaging parts are preferably water-soluble, so that no packaging parts remain in the dishwasher, which could then lead to problems in the dishwasher. It is not necessary for the at least two packaging parts to be different. They can preferably be made from the same material and in the same way. In a preferred embodiment, these are two parts of a water-soluble film, in particular two parts of a water-soluble film of the same composition.

In a further embodiment, the at least two packaging parts can be made from different materials, eg from different films or from material with two different properties (eg film soluble in hot and cold water). In this Embodiment, it is preferred that a water-soluble film and another packaging part, which was produced by injection molding, are combined.

According to a particularly preferred embodiment of the present invention, the water-soluble cover comprises at least one at least partially plastically deformed film. In particular, this plastic deformation of the film can be produced by methods known to those skilled in the art, such as deep drawing (with and without applying a vacuum), blow molding or stamping. In particular, the water-soluble covering comprises at least one at least partially plastically deformed film that was produced by deep-drawing.

A preferred subject matter of the present invention is a detergent or cleaning agent, preferably dishwashing detergent, in particular machine dishwashing detergent, which additionally comprises at least one solid, in particular particulate phase and optionally at least one further liquid/gel-like or solid phase.

The at least one solid phase and the at least one gel can be arranged within the water-soluble envelope in any combination with one another. A solid phase can be arranged on top of or next to a gel phase. In this embodiment, the washing or cleaning agent according to the invention, preferably dishwashing detergents, in particular machine dishwashing detergents, has a solid phase and a gel phase or gel. It is also conceivable that a solid phase is surrounded by gel phases. Embedding one phase in another is also included according to the invention. In a further particularly preferred arrangement, the gel is in cast form, for example in the form of a gel core surrounded by a solid phase. There can also be 2 or more separate cavities that are filled with at least one gel phase. In this embodiment, the washing or cleaning agent comprises two gel phases, it being possible for the two gel phases to have different compositions.

According to a preferred embodiment, there are 3, 4, 5 or 6 or more separate cavities which are filled with one or more of the gel phases. Such detergents or cleaning agents preferably comprise 3, 4, 5 or 6 or more gel phases, it being possible for these gel phases to have the same or also different compositions.

"Solid" in this context means that the composition is in solid form under standard conditions (temperature 25° C., pressure 1013 mbar). Suitable solid phases are, on the one hand, granular mixtures of a solid composition, such as, for example, powder and/or granules, in particular powdery phases. Also suitable according to the invention are solid compositions/phases which have an increased dimensional stability compared to the loose powder, for example powder or granulate preparation, which before or after Inclusion in the film were compacted by compression, for example by restoring forces of the film after thermoforming or directly compressed compositions such as compressed products or tablets. This at least one solid phase can be in direct contact with the gel phase. According to the invention are also detergent or cleaning agent portions, in particular multi-chamber bags, in which the solid and the gel/the gel phase are present in close proximity but separate from one another. The two chambers can be separated, for example, by a film, in particular a water-soluble film, or by a sealed seam (preferably a sealed seam of 3 mm or less). According to the invention, chambers of a multi-chamber pouch are arranged one above the other or next to one another. Furthermore, there are also mixtures of single or multi-chamber bags, which comprise a gel-like phase according to the invention and, separately from this, at least one solid phase, which come into contact by arrangement, eg by folding and fixing a pouch, or by storage at a distance of less than 3 mm , For example in a packaging bag or a device for portioned dosing, according to the invention.

A granular mixture is to be understood as a powdery phase within the meaning of the present invention, which is formed from a large number of loose, solid particles, which in turn comprise so-called grains. According to the invention, the term powdery phase includes powders and/or granules according to the following definition.

A grain is a designation for the particulate components of powders (grains are the loose, solid particles), dusts (grains are the loose, solid particles), granules (loose, solid particles are agglomerates of several grains) and other granular mixtures. A preferred embodiment of the granular mixture of the composition of the solid phase is the powder and/or the granulate, if “powder” or “granulate” is mentioned here, it also includes mixtures of different powders or different granulates .

The agent of the portion according to the invention thus comprises at least one solid phase of a free-flowing, granular mixture of a solid composition, in particular a powder, and at least one gel phase, as defined above.

A particularly preferred subject of the present invention are detergents or cleaning agents, in particular detergent or cleaning agent portions, special machine dishwashing detergent portions, in which the gel / the gel phase is in direct contact, for example in a chamber, with the at least one solid, preferably granular phase is.

Furthermore, it is preferred that the at least one solid phase and the at least one gel are in direct contact with one another. In this case there should be no negative interaction between the solid phase and the gel phase. No negative interaction means here, for example, that no ingredients or solvents pass from one phase to the other or that the stability, in particular storage stability, preferably at 4 weeks and 30 °C storage temperature, and / or the aesthetics of the product in any form, for example by Color change, the formation of edges that appear moist, the boundary between the two phases becoming blurred, or the like.

The at least one solid phase of the present invention comprises a granular mixture of a solid composition, in particular it is in powdered and free-flowing form. The washing or cleaning agent according to the invention thus comprises at least one solid, powdery and free-flowing phase, and at least one gel phase, which contains at least one water-soluble zinc salt, in particular zinc sulfate and/or zinc acetate, in particular zinc acetate, and at least one polyvinyl alcohol, at least PVOH and/or its gel former Derivatives, particularly preferably at least PVOH, and glycerol.

The pourability of a granular mixture, in particular of a powdery solid, of the powdery phase, preferably of the powder and/or granulate, relates to its ability to pour freely under its own weight. The pourability is determined by measuring the flow time of 1000 ml washing or cleaning agent powder from a standardized flow test funnel with an outlet diameter of 16.5 mm, which is initially closed in its outlet direction, by measuring the time it takes for the granular mixture to flow out completely, especially the powdery one Phase, preferably of the powder and/or granules, e.g. the powder is measured after opening the outlet and compared with the outlet speed (in seconds) of a standard test sand, the outlet speed of which is defined as 100%. The defined sand mixture for calibrating the trickle apparatus is dry sea sand. Sea sand with a particle diameter of 0.4 to 0.8 mm is used, available for example from Carl Roth, Germany CAS no. [14808-60-7]. Before the measurement, the sea sand is dried for 24 h at 60° C. in a drying cabinet on a plate with a maximum layer height of 2 cm.

Preferred embodiments of the solid phases according to the invention have an angle of repose/repose of from 26 to 35, from 27 to 34, from 28 to 33, the angle of repose is determined according to the method mentioned below after 24 h after the preparation of the granular mixture of the solid composition, in particular the powdered solid phase, preferably the powder and/or granules and storage at 20 °C. Such angles of repose have the advantage that the cavities can be filled with the at least one solid, preferably granular phase comparatively quickly and precisely.

To determine the angle of repose (or also known as the angle of repose) of the at least one solid, preferably granular phase, a powder funnel with a capacity of 400 ml and an outlet with a diameter of 25 mm is hung straight on a tripod. The hopper is moved upwards at a speed of 80 mm/min using a manually operated knurled wheel, so that the granular mixture, in particular the powdery phase, preferably the powder and/or granules, e.g. the powder, trickles out. This forms a so-called material cone. The height of the cone of repose and the diameter of the cone of repose are determined for the individual solid phases. The angle of repose is calculated from the quotient of the heap of repose and the diameter of the cone of repose * 100.

Particularly suitable are such granular mixtures of a solid composition, in particular such powdery phases, preferably the powders and/or granules, e.g. the powders which have a flowability in % of the standard test material specified above of greater than 40%, preferably greater than 50, in particular greater than 55 %, particularly preferably greater than 60%, particularly preferably between 63% and 80%, for example between 65% and 75%. Particularly suitable are those granular mixtures of a solid composition, in particular those powders and/or granules, which have a pourability in % of the standard test substance specified above of greater than 40%, preferably greater than 45%, in particular greater than 50%, particularly preferably greater than 55 %, particularly preferably greater than 60%, the pourability being measured 24 hours after the powder has been produced and stored at 20°C.

Lower values for the pourability are rather unsuitable since, from the point of view of process technology, precise dosing of the granular mixture, in particular the powdered phase, preferably the powder and/or granules, for example the powder, is necessary. In particular, the values greater than 50%, in particular greater than 55%, preferably greater than 60% (the flowability being measured 24 h after the production of the powder and storage at 20° C.) have proven to be advantageous because the good dosability the granular mixture, in particular the pulverulent phases, preferably the powder and/or granules, eg powder, result in only slight fluctuations in the metered quantity or the composition. The more precise dosing leads to a constant product performance, economic losses due to overdosing are thus avoided. Furthermore, it is advantageous that the granular mixture, in particular the pulverulent phase, preferably the powder and/or granulate, for example the powder are easy to dose, so you achieve a faster flow of the dosing process. Furthermore, such a good flowability better prevents the granular mixture, in particular the powdery phase, preferably the powder and/or granules, e.g. the powder, from getting onto the part of the water-soluble cover that is intended for the production of the sealed seam and is therefore possible should remain granule-free, in particular powder-free.

The granular mixture of the solid composition of the present invention serving as the solid phase is preferably in a free-flowing form (particularly preferably as a free-flowing powder and/or free-flowing granules). The agent of the portion according to the invention thus preferably comprises at least one solid phase of a free-flowing, granular mixture of a solid composition, in particular a powder, and at least one previously defined gel or one previously defined gel phase.

The washing or cleaning agent according to the invention, preferably dishwashing detergents, in particular machine dishwashing detergents, preferably comprises at least one surfactant. This surfactant is selected from the group of anionic, nonionic and cationic surfactants. The washing or cleaning agent according to the invention can also contain mixtures of several surfactants selected from the same group.

According to the invention, the at least one solid, preferably granular phase and/or the gel comprise at least one surfactant. It is possible for only the at least one solid, preferably granular phase or only the gel to comprise at least one surfactant. If both phases comprise a surfactant, they are preferably different surfactants. However, it is also possible for the solid and gel phases to have the same surfactant or surfactants. At least one solid and/or gel phase according to the invention preferably contains at least one nonionic surfactant. All nonionic surfactants known to those skilled in the art can be used as nonionic surfactants. Low-foaming nonionic surfactants are preferably used, in particular alkoxylated, especially ethoxylated, low-foaming nonionic surfactants, such as, for example, alkyl glycosides, alkoxylated, preferably ethoxylated or ethoxylated and propoxylated fatty acid alkyl esters, polyhydroxy fatty acid amides or amine oxides. Particularly preferred nonionic surfactants are specified in more detail below.

Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE). In addition to these nonionic surfactants, fatty alcohols with more than 12 EO can also be used. Examples of this are tallow fatty alcohol with 14 EO, 25 EO, 30 EO or 40 EO.

Particular preference is given to ethoxylated nonionic surfactants consisting of C _6-20 monohydroxyalkanols or C _6-20 alkylphenols or C _16-20 fatty alcohols and more than 12 mol, preferably more than 15 mol and in particular greater than 20 moles of ethylene oxide per mole of alcohol were recovered. A particularly preferred nonionic surfactant is obtained from a straight-chain fatty alcohol having 16 to 20 carbon atoms (C _16-20 alcohol), preferably a C ₁₈ alcohol and at least 12 moles, preferably at least 15 moles and in particular at least 20 moles of ethylene oxide. Among these, the so-called "narrow range ethoxylates" are particularly preferred.

Surfactants to be used with preference come from the groups of alkoxylated nonionic surfactants, in particular ethoxylated primary alcohols and mixtures of these surfactants with structurally complex surfactants such as polyoxypropylene/polyoxyethylene/polyoxypropylene ((PO/EO/PO) surfactants). Such (PO/EO/PO) nonionic surfactants are also distinguished by good foam control.

bevorzugt, in der R¹ für einen geradkettigen oder verzweigten, gesättigten oder einbeziehungsweise mehrfach ungesättigten C_6-24-Alkyl- oder-Alkenylrest steht; jede Gruppe R² beziehungsweise R³ unabhängig voneinander ausgewählt ist aus -CH₃, -CH₂CH₃, -CH₂CH₂-CH₃, -CH(CH₃)₂ und die Indizes w, x, y, z unabhängig voneinander für ganze Zahlen von 1 bis 6 stehen.In the context of the present invention, particularly preferred nonionic surfactants have been found for the low-foaming nonionic surfactants which have alternating ethylene oxide and alkylene oxide units. Among these, preference is in turn given to surfactants with EO-AO-EO-AO blocks, in which case one to ten EO or AO groups are bonded to one another before a block of the other groups follows. Here are nonionic surfactants of the general formula

preferably in which R ¹ is a straight-chain or branched, saturated or partially unsaturated C _6-24 -alkyl or alkenyl radical; each group R ² or R ³ is independently selected from -CH ₃ , -CH ₂ CH ₃ , -CH ₂ CH ₂ -CH ₃ , -CH(CH ₃ ) ₂ and the indices w, x, y, z are independent of one another are integers from 1 to 6.

Preferred nonionic surfactants of the above formula can be prepared from the corresponding alcohols R ¹ —OH and ethylene or alkylene oxide by known methods. The radical R ¹ in the above formula can vary depending on the origin of the alcohol. If native sources are used, the radical R ¹ has an even number of carbon atoms and is usually unbranched, with the linear radicals from alcohols of natural origin having 12 to 18 carbon atoms, for example from coconut, palm, tallow or oleyl alcohol, are preferred. Alcohols obtainable from synthetic sources are, for example, the Guerbet alcohols or a mixture of methyl-branched or linear and methyl-branched radicals in the 2-position, such as are usually present in oxo alcohol radicals. Regardless of the type of alcohol used to produce the nonionic surfactants contained in the agents, nonionic surfactants are preferred in which R ¹ in the above formula is an alkyl radical with 6 to 24, preferably 8 to 20, particularly preferably 9 to 15 and in particular 9 to 11 carbon atoms.

A suitable alkylene oxide unit, which is present in the preferred nonionic surfactants alternating with the ethylene oxide unit, is, in addition to propylene oxide, in particular butylene oxide. However, other alkylene oxides in which R ² or R ³ are independently selected from --CH ₂ CH ₂ --CH ₃ or --CH(CH ₃ ) ₂ are also suitable. Preference is given to using nonionic surfactants of the above formula where ^R.sup.2 or ^R.sup.3 is a --CH.sub.3 radical, w and x are independently ₃ or 4, and y and z are independently 1 or 2.

Other nonionic surfactants preferably used in the solid phase are nonionic surfactants of the general formula R ¹ O(AlkO) _x M(OAlk) _y OR ² , where
R ¹ and R ² independently represent a branched or unbranched, saturated or unsaturated, optionally hydroxylated alkyl radical having 4 to 22 carbon atoms; Alk represents a branched or unbranched alkyl group having 2 to 4 carbon atoms; x and y independently represent values between 1 and 70; and M is an alkyl radical from the group CH ₂ , CHR ³ , CR ³ R4, CH ₂ CHR ³ and CHR ³ CHR ⁴ , where R ³ and R ⁴ are independently branched or unbranched, saturated or unsaturated alkyl radicals having 1 bis 18 carbon atoms.

Nonionic surfactants of the general formula are preferred here

R ¹ -CH(OH)CH ₂ -O(CH ₂ CH ₂ O)x CH ₂ CHR(OCH ₂ CH ₂ ) _y -CH ₂ CH(OH)-R ² ,

where R, R ¹ and R ² independently represent an alkyl group or alkenyl group having 6 to 22 carbon atoms; x and y independently represent values between 1 and 40.

Compounds of the general formula are particularly preferred here

R ¹ -CH(OH)CH ₂ -O(CH ₂ CH ₂ O)x CH ₂ CHR(OCH ₂ CH ₂ ) _y O-CH ₂ CH(OH)-R ² ,

in which R is a linear, saturated alkyl radical having 8 to 16 carbon atoms, preferably 10 to 14 carbon atoms, and n and m independently have values of 20 to 30. Corresponding compounds can be obtained, for example, by reacting alkyl diols HO—CHR—CH ₂ —OH with ethylene oxide, which is followed by a reaction with an alkyl epoxide to close the free OH functions with formation of a dihydroxy ether.

• w, x, y und z für Werte zwischen 0,5 und 120 stehen, wobei x, y und/oder z auch 0 sein können.

Durch den Zusatz der vorgenannten nichtionischen Tenside der allgemeinen Formel R¹-CH(OH)CH₂O-(AO)_w-(A'O)_x-(A"0)_y-(A'''O)_z-R², nachfolgend auch als "Hydroxymischether" bezeichnet, kann überraschenderweise die Reinigungsleistung erfindungsgemäßer Zubereitungen deutlich verbessert werden und zwar sowohl im Vergleich zu Tensid-freien System wie auch im Vergleich zu Systemen, die alternative nichtionischen Tenside, beispielsweise aus der Gruppe der polyalkoxylierten Fettalkohole enthalten.Preferred nonionic surfactants here are those of the general formula R ¹ -CH(OH)CH ₂ O-(AO) _w -(AO) _x -(A"O) _y -(A'''O) _z -R ² , in the

• w, x, y and z stand for values between 0.5 and 120, where x, y and/or z can also be 0.

By adding the aforementioned nonionic surfactants of the general formula R ¹ -CH(OH)CH ₂ O-(AO) _w -(A'O) _x -(A"0) _y -(A'''O) _z -R ² , also referred to below as "hydroxy mixed ether", surprisingly the cleaning performance of preparations according to the invention can be significantly improved, both compared to surfactant-free systems and compared to systems containing alternative nonionic surfactants, for example from the group of polyalkoxylated fatty alcohols.

The use of these nonionic surfactants having one or more free hydroxyl groups on one or both terminal alkyl radicals can significantly improve the stability of the enzymes contained in the detergent or cleaning agent preparations according to the invention.

Insbesondere bevorzugt sind Tenside der vorstehenden Formel, in denen R¹ für C₇ bis C₁₃, n für eine ganze natürliche Zahl von 16 bis 28 und R²für C₈ bis C₁₂ steht.Preference is given in particular to those end-capped poly(oxyalkylated) nonionic surfactants which, according to the following formula

Particular preference is given to surfactants of the above formula in which R ¹ is C ₇ to C ₁₃ , n is an integer from 16 to 28 and R ² is C ₈ to C ₁₂ .

Surfactants of the formula R ¹ O[CH ₂ CH(CH ₃ )O] _x [CH ₂ CH ₂ O] _y CH ₂ CH(OH)R ² are particularly preferred, in which R ¹ represents a linear or branched aliphatic hydrocarbon radical with 4 to 18 carbon atoms or mixtures thereof, R ² denotes a linear or branched hydrocarbon radical having 2 to 26 carbon atoms or mixtures thereof and x has values between 0.5 and 1.5 and y has a value of at least 15. The group of these nonionic surfactants includes, for example, the C _2-26 fatty alcohol (PO) ₁ -(EO) _15-40 -2-hydroxyalkyl ethers, in particular also the C _8-10 fatty alcohol (PO) ₁ -(EO) ₂₂ -2 -hydroxydecyl ether.

Such end-capped poly(oxyalkylated) nonionic surfactants of the formula R ¹ O[CH ₂ CH ₂ O] _x [CH ₂ CH(R ³ )O] _y CH ₂ CH(OH)R ² , in which R ¹ and R ² independently represent a linear or branched, saturated or mono- or polyunsaturated hydrocarbon radical having 2 to 26 carbon atoms, R ³ is independently selected from -CH ₃ , -CH ₂ CH ₃ , -CH ₂ CH ₂ -CH 3, -CH(CH ₃ ) ₂ , but preferably represents -CH ₃ , and x and y independently represent values between 1 and 32, where nonionic surfactants with R ³ = -CH ₃ and values for x from 15 to 32 and y from 0.5 and 1.5 are most preferred.

Other preferably usable nonionic surfactants are the end-capped poly(oxyalkylated) nonionic surfactants of the formula R ¹ O[CH ₂ CH(R ³ )O] _x [CH ₂ ] _k CH(OH)[CH ₂ ] _j OR ² in which R ¹ and R ² represents linear or branched, saturated or unsaturated, aliphatic or aromatic hydrocarbon radicals having 1 to 30 carbon atoms, R ³ represents H or a methyl, ethyl, n-propyl, isopropyl, n-butyl, 2 -butyl or 2-methyl-2-butyl radical, x has values between 1 and 30, k and j have values between 1 and 12, preferably between 1 and 5.

R ¹ and R ² are preferably linear or branched, saturated or unsaturated, aliphatic or aromatic hydrocarbon radicals having 6 to 22 carbon atoms, radicals having 8 to 18 carbon atoms being particularly preferred. H, -CH ₃ or -CH ₂ CH ₃ are particularly preferred for the radical R ³ . Particularly preferred values for x are in the range from 1 to 20, in particular from 6 to 15.

As described above, each R ³ in the above formula can be different when x>2. This allows the alkylene oxide unit in the square brackets to be varied. For example, when x is 3, the R ³ group may be selected to form ethylene oxide (R ³ = H) or propylene oxide (R ³ = CH ₃ ) moieties which may be joined in any order, e.g. (EO)( PO)(EO), (EO)(EO)(PO), (EO)(EO)(EO), (PO)(EO)(PO), (PO)(PO)(EO) and (PO)( PO)(PO). The value 3 for x was selected here as an example and can certainly be larger, with the range of variation increasing with increasing x values and including, for example, a large number of (EO) groups combined with a small number of (PO) groups, or vice versa .

The given carbon chain lengths and degrees of ethoxylation or alkoxylation of the nonionic surfactants represent statistical mean values, which can be a whole or a fractional number for a specific product. Due to the manufacturing process, commercial products of the formulas mentioned usually do not consist of an individual representative, but of mixtures, which means that average values and fractional numbers can result both for the C chain lengths and for the degrees of ethoxylation or alkoxylation.

8. h) And optionally 0.3 to 0.6% by weight of a zinc salt, preferably zinc acetate anhydrate.

All anionic surface-active substances are suitable as anionic surfactants in the agents. These are characterized by a water-solubilizing, anionic group such as. B. a carboxylate, sulfate or sulfonate group and a lipophilic alkyl group having about 8 to 30 carbon atoms. In addition, the molecule can contain glycol or polyglycol ether groups, ester, ether and amide groups and hydroxyl groups. Suitable anionic surfactants are preferably in the form of the sodium, potassium and ammonium and the mono-, di- and trialkanolammonium salts with 2 to 4 carbon atoms in the alkanol group, but also zinc, manganese (II), magnesium, calcium or Mixtures of these can serve as counterions. Preferred anionic surfactants are alkyl sulfates, alkyl polyglycol ether sulfates and ether carboxylic acids having 10 to 18 carbon atoms in the alkyl group and up to 12 glycol ether groups in the molecule.

Instead of the surfactants mentioned or in combination with them, cationic and/or amphoteric surfactants such as betaines or quaternary ammonium compounds can also be used. However, it is preferred that no cationic and/or amphoteric surfactants are used.

Surfactants influence the opacity of the gel phase. In another embodiment, the gel is therefore free from nonionic surfactants, in particular free from surfactants. "Free from" means that the gel contains less than 1.0% by weight and in particular less than 0.1% by weight, preferably no surfactant or no nonionic surfactant).

Preferred washing or cleaning agents according to the invention, preferably dishwashing detergents, in particular machine dishwashing detergents, are further characterized in that they contain less than 1.0% by weight and in particular less than 0.1% by weight, preferably no anionic surfactant.

The gel is preferably essentially free of anionic surfactants. Substantially free means that the gel contains less than 0.05% by weight of anionic surfactant, based on the total weight of the gel.

In this context, it has been shown that the presence of 1% by weight of anionic surfactant in the at least one gel phase leads to poorer foaming behavior and poorer rinsing behavior of the composition as a whole. Furthermore, higher amounts of anionic surfactants have a negative effect on curing. According to a particularly preferred embodiment, the gel contains less than 1% by weight, preferably less than 0.5% by weight, in particular less than 0.05% by weight, of fatty acid salts or soaps.

According to a further embodiment, the gel can contain sugar. According to the invention, sugars include sugar alcohols, monosaccharides, disaccharides and oligosaccharides.

The proportion of sucrose is 0% by weight to 30% by weight, in particular 5% by weight to 25% by weight, particularly preferably 10% by weight to 20% by weight, based on the weight of the gel phase . In higher amounts, the sugar does not completely dissolve in the gel phase and causes the same to become cloudy.

Preferred salts are the salts of polycarboxylic acids such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, GLDA, MGDA and mixtures of these.

Also suitable as organic builders are polymeric polycarboxylates (organic polymers with a large number of (especially more than ten) carboxylate functions in the macromolecule), polyaspartates, polyacetals and dextrins.

In addition to their builder effect, the free acids typically also have the property of an acidifying component. Particular mention should be made here of citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any mixtures of these.

In addition to the aforementioned builders, the detergents or cleaning agents according to the invention can also contain alkali metal hydroxides. These alkali carriers are particularly preferred in the detergents or cleaning agents and in particular in the at least one gel phase, preferably only in small amounts, preferably in amounts below 10% by weight, more preferably below 6% by weight, preferably below 5% by weight between 0.1 and 5% by weight and in particular between 0.5 and 5% by weight, based in each case on the total weight of the detergent or cleaning agent. Alternative washing or cleaning agents according to the invention are free from alkali metal hydroxides.

Detergents or cleaning agents according to the invention preferably contain enzyme(s) as a further component in the at least one solid phase and/or the at least one gel phase. These include in particular proteases, amylases, lipases, hemicellulases, cellulases, perhydrolases or oxidoreductases, and preferably mixtures thereof. These enzymes are in principle of natural origin; Based on the natural molecules, improved variants are available for use in detergents or cleaning agents, which are preferably used accordingly. Detergents or cleaning agents according to the invention preferably contain enzymes in total amounts of 1×10 ^-6 % by weight to 5% by weight, based on active protein. The protein concentration can be determined using known methods, for example the BCA method or the Biuret method.

Among the proteases, those of the subtilisin type are preferred. Examples of this are the subtilisins BPN' and Carlsberg and their further developed forms, the protease PB92, the subtilisins 147 and 309, the alkaline protease from Bacillus lentus, subtilisin DY and the enzymes thermitase, which can be assigned to the subtilases, but no longer to the subtilisins in the narrower sense, Proteinase K and the proteases TW3 and TW7

Examples of amylases which can be used according to the invention are the α-amylases from Bacillus licheniformis, from B. amyloliquefaciens, from B. stearothermophilus, from Aspergillus niger and A. oryzae and the further developments of the aforementioned amylases which have been improved for use in detergents or cleaning agents.

According to the invention, oxidoreductases, for example oxidases, oxygenases, catalases, peroxidases such as halo-, chloro-, bromo-, lignin-, glucose- or manganese peroxidases, dioxygenases or laccases (phenol oxidases, polyphenol oxidases) can be used to increase the bleaching effect. Advantageously, preferably organic, particularly preferably aromatic, compounds that interact with the enzymes are additionally added in order to increase the activity of the relevant oxidoreductases (enhancers) or to ensure the flow of electrons in the case of greatly differing redox potentials between the oxidizing enzymes and the soiling (mediators). A protein and/or enzyme can be protected against damage such as, for example, inactivation, denaturation or decomposition, for example due to physical influences, oxidation or proteolytic cleavage, particularly during storage. In the case of microbial production of the proteins and/or enzymes, inhibition of proteolysis is particularly preferred, particularly if the agents also contain proteases. Detergents or cleaning agents can contain stabilizers for this purpose; the provision of such means represents a preferred embodiment of the present invention.

Cleaning-active proteases and amylases are generally not provided in the form of the pure protein but rather in the form of stabilized preparations that can be stored and transported. These ready-made preparations include, for example, those produced by granulation, extrusion or lyophilization obtained solid preparations or, especially in liquid or gel-like agents, solutions of the enzymes, advantageously as concentrated as possible, low in water and / or mixed with stabilizers or other auxiliaries.

Alternatively, the enzymes for the at least one solid and/or the gel can be encapsulated, for example by spray drying or extrusion of the enzyme solution together with a preferably natural polymer, or in the form of capsules, for example those in which the enzymes are enclosed as in a set gel or in those of the core-shell type, in which an enzyme-containing core is coated with a water, air and/or chemical impermeable protective layer. Additional active substances, for example stabilizers, emulsifiers, pigments, bleaching agents or dyes, can also be applied in superimposed layers. Such capsules are applied by methods known per se, for example by shaking or rolling granulation or in fluid-bed processes. Advantageously, such granules, for example due to the application of polymeric film formers, produce little dust and are stable in storage due to the coating.

Furthermore, it is possible to formulate two or more enzymes together, so that a single granulate has several enzyme activities.

As can be seen from the above, the enzyme protein forms only a fraction of the total weight of conventional enzyme preparations. Protease and amylase preparations used according to the invention contain between 1 and 40% by weight, preferably between 2 and 30% by weight, particularly preferably between 3 and 25% by weight, of the enzyme protein. Preference is given in particular to detergents or cleaning agents which, based on their total weight, contain from 0.1 to 12% by weight, preferably from 0.2 to 10% by weight and in particular from 0.5 to 8% by weight of the respective Contain enzyme preparations.

However, the use of Tegopren types 5843 and 5863 is less preferred when used on hard surfaces made of glass, in particular glassware, since these silicone surfactants can be absorbed by glass. In a particular embodiment of the invention, the additives mentioned are omitted.

Insofar as it is stated in the present application that the washing or cleaning agent according to the invention comprises something as a whole or in the gel, it is also to be regarded as disclosed that the washing or cleaning agent or the respective phase can consist of it. In the exemplary embodiment below, the washing or cleaning agent according to the invention is described in a non-limiting manner.

Examples:

Detergents or cleaning agents according to the invention were produced which comprised a gel phase or a solid phase and a gel phase. Different geometries were realized here. Furthermore, detergents or cleaning agents were produced which comprised two solid phases and one gel phase. Detergents or cleaning agents were also produced which comprised a solid phase and 3, 4 and 5 gel phases (of the same or different composition). The following information relates to % by weight of active substance, based on the total weight of the phase in question (unless otherwise stated). Table 1: The gels had the following compositions (in each case based on the total amount of the gel phase): wt% wt% Water-soluble zinc salt (preferably zinc acetate anhydrate) 0 0.3-0.6 glycerin 23.0-29.5 25-28 1,3-propanediol 27 - 35 30:5-33 Polycarboxylate copolymer with sulfonic acid containing groups 5-10.5 7-10.5 Nonionic surfactant(s), eg fatty alcohol alkoxylate, preferably 20-40 EO, optionally endcapped 0-2.3 0.5-1.5 polyethylene glycol average Mr 200-600, (e.g. PEG 400 (INCI) 12-18.5 12-18.5 PVOH 12-18 12:7-15:5 dye solution 0.0 - 1.5 0.0 - 1.5 Misc., Other Actives, Organic Solvents, Perfume, Processing Aids add 100 add 100

The solid phases and the gel could be combined with one another as desired. The spatial configuration of the gel phase, which was liquid after mixing the ingredients and dimensionally stable within a maximum setting time of 1 minute, was determined by the spatial configuration of the solid phase and by commercially available or self-designed forms. A water-soluble cover in the form of an open pouch was produced by deep-drawing a film containing PVOH (Monosol M8630). A liquid composition was poured into this open cavity, which after hardening gave the gel, the open pouch was then sealed by laying a second film and sealing with a heat seal.

To measure the syneresis, ellipsoids (castings) are cast from the gel to be tested (dimensions: b=16.6, l=23mm, h=5mm+2mm bar). These castings were stored at room temperature (20° C.) for one and seven days. To determine the mass ratios, the ellipsoids (per measurement, 15 pieces each) were dabbed with an absorbent cloth and the proportion of dabbed liquid compared to the mass of the remaining casting was determined.

A device with two different ramps is used to measure the solidification time. The length of the front ramp area is: 300mm, angle 28°, width tapering from 100 to 80mm; the length of the rear ramp area: 200mm, angle 110°, width tapering from 80mm to 65mm. The device has a temperature of 25°C +/-2°C. 50 g of the gel to be tested are poured onto the ramp at a temperature of 125° C. and the time required for the gel flowing down the ramp to solidify is measured. Table 2: Gel phase compositions In wt% E1 E2 E2 Zinc acetate anhydrous 0.5 0.5 0.5 Polymer comprising acrylic acid and amidopropylsulfonic acid containing monomers 10 10 10 1,3-propanediol 32 32 32 glycerin 26 26 26 Nonionic Surfactant* 0 1.5 0.8 PEG 400 15 15 15 PVOH (Mowiol 4-88) 15 15 15 Misc (including processing aids, pH adjusters, perfume, dye, residual water) add 100 add 100 add 100 gelling time / min < 30s < 30s < 30s * Fatty alcohol alkoxylate, preferably 20-40 EO, endcapped

Alternatively, fatty alcohol ethoxylate can also be used, preferably 20-40 EO without endcap.

Corresponding formulations were prepared according to Table 2. The formulations E1 and E2 showed a syneresis of less than 1.5% after storage for 7 days at room temperature. Table 3: The solid, granular mixtures of a solid composition, in particular powdery and free-flowing phases, had the following preferred composition: wt% citrate, sodium salt 15-20 Phosphonate (e.g. HEDP) 0; 2.5-7.5 MGDA, Na salt 0-25 Disilicate, Na salt 5-35 soda 10-25 SILVER PROTECTION (e.g. cysteine) 0.0-1.0 Percarbonate, Na salt 10-15 Bleach catalyst (preferably Mn-based) 0.02-0.5 Bleach activator (e.g. TAED) 1-3 Nonionic surfactant(s), eg fatty alcohol alkoxylate, preferably 20-40 EO, optionally endcapped 2.5-10 polycarboxylate 4-10 cationic copolymer 0 - 0.75 Disintegrant - (ex. Crosslinked PVP) 0-1.5 Protease Preparation (tq) 1.5-5 Amylase Preparation (tq) 0.5-3 Perfume 0.05-0.25 dye solution 0.0-1 Zn salt (e.g. acetate) 0.1-0.3 sodium sulfate 0.0 - 10 water 0.0-1.5 pH adjusting agent (e.g. citric acid) 0-1.5 process aids 0-5

1.0 g of the gel phases according to Table 2 were filled into a pouch comprising polyvinyl alcohol (as described above). In addition, solid phases in the form of a free-flowing solid according to Table 3 were applied in an amount of 17.5 g and sealed as described above. Despite the addition of the particulate phase to the gel, there was no mixing of the gel and particulate phase just 30 seconds after the dissolved gel had been introduced into the corresponding depressions in the thermoformed film.
