Abstract

The present invention relates to a washing or cleaning agent, in particular a cleaning agent for hard surfaces, with two different phases.

Description

The present invention relates to a washing or cleaning agent, in particular a cleaning agent for hard surfaces, with at least two mutually different phases.

Washing or cleaning agents are usually in solid form (for example as a powder) or in liquid form (or also as a flowing gel). In particular, liquid detergents or cleaning agents are enjoying increasing popularity with consumers.

Solid washing or cleaning agents have the advantage that, in contrast to liquid washing or cleaning agents, they do not require any preservatives. Liquid supply forms are increasingly gaining acceptance on the market, in particular because of their rapid solubility and the associated rapid availability of the active ingredients they contain. This offers the consumer the opportunity to use shorter washing programs and still get a good cleaning performance.

Furthermore, consumers have become accustomed to the convenient dosing of pre-portioned automatic detergents or cleaning agents, such as dishwashing detergents, and use these products in the form of tablets (solid detergents or cleaning agents) or in the form of bags, which are usually provided with a liquid detergent - or detergents are filled, whereby bags filled with powder are also possible as single-use portions. One-time portions in water-soluble bags are enjoying increasing popularity with consumers not only because the consumer no longer comes into contact with the chemical composition, but not least because of the attractive appearance of the bags. The appearance of the dosage form is becoming increasingly important. In addition to good cleaning performance and adequate storage stability, good optics are one of the reasons for choosing a product. Products stored in bags, however, often change their visual appearance, which for the consumer often gives rise to associations with reduced performance and with poorer cleaning performance.

From the consumer's point of view, it is now desirable to combine the advantages of both supply forms and to provide a form of administration which is improved compared to the prior art, in particular for usually liquid detergents or cleaning agents. One-time portioning should be possible and, at the same time, a visually appealing appearance for the consumer should be achieved. Surprisingly, it has been shown that a Formulation of a flexible phase, which is combined with a solid phase, this goal can be achieved.

In a first embodiment, the object on which the present application is based is therefore achieved by a washing or cleaning agent which comprises at least one first phase and at least one different second phase, the at least one first phase being solid and the at least one second phase comprises at least one polymer and at least one polyhydric alcohol.

A phase in the sense 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. Different phases can preferably be distinguished optically. For the consumer, the at least one first phase can be clearly distinguished from the at least one second phase. If the washing or cleaning agent according to the invention has more than one first phase, then these can also be differentiated from one another with the naked eye, because they differ from one another, for example, in terms of color. The same applies if there are two or more second phases. In this case, too, an optical differentiation of the phases is possible, for example on the basis of a color or transparency difference. Phases in the sense of the present invention are thus self-contained areas that can be visually distinguished from one another by the consumer with the naked eye. When used, the individual phases can have different properties, such as, for example, the speed with which the phase dissolves in water and thus the speed and the sequence in which the ingredients contained in the respective phase are released.

According to the invention, the at least one second phase is dimensionally stable at room temperature. During production, the at least one polymer is brought into contact with the at least one polyhydric alcohol. This gives a flowable mixture which can be brought into a desired shape. After a certain period of time, a second phase is obtained, which remains in the specified shape, i.e. is dimensionally stable. This period of time, the solidification time, is preferably 15 minutes or less, preferably 10 minutes or less, particularly preferably 5 minutes. The at least one second phase yields to pressure, but does not deform as a result, but rather returns to the initial state after the pressure has ceased. The at least one second phase is preferably elastic, in particular linear-elastic. The at least one second phase is also preferably transparent, which results in a good visual impression.

The at least one second phase is cut-resistant. It can be cut, for example, with a knife after solidification, without it being destroyed any further apart from the cut made. Furthermore, the at least one second phase is particularly flexible. Due to its flexibility and elasticity, it can take any shape. This also means breaking strength, which enables good handling, particularly with regard to transport and storage, but also consumption.

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 goes without saying that the examples contained herein are intended to describe and illustrate the invention, but not to restrict it, and in particular the invention is not limited to these examples. Unless otherwise stated, all percentages are percentages by weight. Numeric ranges given in the format "from x to y" include the stated values. If several preferred numerical ranges are given in this format, it is understood that all ranges resulting from the combination of the various endpoints are also recorded.

"At least one" as used herein means 1 or more, i. 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. In relation to an ingredient, the information relates 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. that one type of bleach catalyst or a mixture of several different bleach catalysts can be meant. Together with weight information, the information relates to all compounds of the specified type that are contained in the composition / mixture, i.e. that the composition does not contain any further compounds of this type beyond the specified amount of the corresponding compounds.

If reference is made here to molar masses, these details always relate to the number-average molar mass M _n , unless explicitly stated otherwise. The number average of the molar mass can be determined, for example, by means of gel permeation chromatography (GPC) according to DIN 55672-1: 2007-08 with THF as the eluent. The weight average molar mass M _w can also be determined by means of GPC, as described for M _n .

All percentages that are given in connection with the compositions described herein relate, unless explicitly stated otherwise, to% by weight, in each case based on the mixture in question.

In a preferred embodiment, the at least one first phase is in compressed form. In this embodiment, the washing or cleaning agent according to the invention thus comprises at least one first solid, compressed phase and at least one second phase which comprises at least one polymer and at least one polyhydric alcohol.

Certain minimum requirements are placed on the formulation of the at least one second phase. As already stated, the second phase must solidify within the shortest possible time. Long solidification times would lead to long production times and thus to high costs. According to the invention, the solidification time means the period of time during which the at least one second phase changes from a flowable state to a dimensionally stable state that is non-flowable at room temperature. Here, room temperature is understood to mean a temperature of 20 ° C. This can take place, without having a restrictive effect, by crosslinking the at least one polymer.

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

Visually, the surface of the second phase should differ significantly from the first phase, for example by a pronounced gloss. The surface of the solid at least one first phase is usually not glossy but matt, dull or dull, so that a gloss enables a good differentiation, which makes the detergent or cleaning agent attractive to the consumer, possible.

A change in volume or shrinkage during storage would be disadvantageous, since this would result in poor consumer acceptance of the product. Leakage of liquid or exudation of constituents from the second phase is also undesirable. Here, too, the visual impression is relevant. The stability of the second phase can be influenced by the escape of liquid, such as for example solvent, so that the constituents are no longer contained in a stable manner and the washing or cleaning effect can thereby also be influenced.

Furthermore, it should be possible for the at least one first phase and the at least one second phase to be in direct contact with one another. In this case there should be no negative interaction between the first phase and the second 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 through Color change, formation of damp-looking edges, blurred border between the two phases or the like is impaired.

It has surprisingly been found that particularly good storage stability is achieved when the second phase is essentially anhydrous. This means that the second phase is preferably essentially free of water. “Essentially free” means here that small amounts of water can be contained in the second 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, no water is used as a solvent for preparing the second phase. The proportion of water in the second phase is in particular 15% by weight or less or 10% by weight or less, especially 7% by weight, or less, in particular 6% by weight or 5% by weight or less , preferably 2% by weight or less, in particular 1% by weight or less, especially 0.5% by weight or less, in particular 0.1% by weight or 0.05% by weight or less. The data in% by weight relate to the total weight of the second phase.

The at least one second phase comprises at least one polymer. The at least one polymer is particularly suitable for forming a network. According to the invention, the at least one second phase can have one polymer, two or more different polymers. In particular, it has one, two or more, in particular one or two, preferably one polymer which is suitable for forming a network. In addition, the at least one second phase can have one or more polymers that do not form a network but lead to a thickening and thus an increase in the dimensional stability of the at least one second phase, so-called thickening polymers. In a preferred embodiment, the at least one second phase therefore comprises at least one, preferably one polymer for network formation and one or more thickening polymers.

The at least one second phase preferably comprises PVA (polyvinyl alcohol) and / or gelatin as polymers suitable for network formation. The at least one second phase also preferably comprises a thickening polymer and, in particular, polycarboxylates as thickening polymer. Polyvinyl alcohols are thermoplastics which are usually produced as a white to yellowish powder by hydrolysis of polyvinyl acetate. Polyvinyl alcohol (PVA) is resistant to almost all anhydrous organic solvents. Polyvinyl alcohols with a molar mass of 30,000 to 60,000 g / mol are preferred.

Gelatine is a mixture of substances made from tasteless animal protein. The main component is denatured or hydrolyzed collagen, which is produced from the connective tissue of various animal species. Gelatin lacks the essential amino acid tryptophan, so it is not considered a full protein. Gelatine swells in water and dissolves when heated from around 50 ° C. When it cools down, a gel forms which, when heated again, becomes liquid again.

Surprisingly, it has been shown that PVA and / or gelatin are particularly suitable for producing second phases that meet the requirements shown above. At least one second phase is therefore particularly preferred, which comprises gelatin and / or PVA and at least one polyhydric alcohol. The at least one second phase particularly preferably comprises gelatin and at least one polyhydric alcohol. The at least one second phase also preferably has PVA and at least one polyhydric alcohol.

According to the invention, the at least one second phase comprises the polymer suitable for network formation in a proportion of about 5% by weight to 40% by weight, in particular from 10% by weight to 35% by weight, preferably 15% by weight to 20% by weight. Significantly lower proportions of polymer, in particular gelatin and / or PVA, do not lead to the formation of a stable gel-like second phase. Rather, a permanent blurring can be observed here. Proportions of more than 40% by weight and in particular more than 20% by weight lead to a prolonged solidification time. The phases remain soft longer, which leads to a longer manufacturing process. The values are based on the total weight of the second phase.

The at least one second phase particularly preferably comprises gelatin. Surprisingly, it has been shown that, with the help of gelatin, dimensionally stable second phases can be produced within a short hardening time. Furthermore, the shape and size of the phases produced in this way remain stable over a long period of time. No shrinkage in size can be observed. It has been shown that the required amount of gelatin used varies depending on the Bloom value. The second phase therefore preferably has gelatin with a Bloom value in the range from 60 to 225. The Bloom value describes the gel strength or gelling power of gelatine. The key figure is the mass in grams that is required for a 0.5 inch diameter punch to deform the surface of a 6.67% gelatine / water mixture four millimeters deep without tearing it. The attempt finds standardized at exactly 10 ° C with a previous aging of the gelatin of 17 hours.

If the at least one second phase comprises gelatin with a Bloom value of 150 or more, in particular from 180 to 225, preferably from 200 to 225, the proportion of gelatin based on the total weight of the second phase is preferably in the range from 10% by weight to 20 % By weight, in particular from 15% by weight to 18% by weight. If the Bloom value is less than 150, in particular from 60 to 120, preferably from 60 to 100, the proportion of gelatin based on the total weight of the second phase is preferably in the range from 15% by weight to 30% by weight, in particular 20 Wt% to 25 wt%. Gelatin with a Bloom value of 180 or more, in particular 200 or more, especially 225, is preferred. Gelatin with a corresponding Bloom value can be used to control the viscosity of the second phase during production. In addition, the amount of gelatine required is less here than when using gelatine with a lower Bloom value, which can lead to a reduction in costs.

If the at least one second phase, in addition to gelatin, also comprises PVA, the toughness of the second phase is increased during production.

Surprisingly, it has been found that gelatine together with anionic polymers or copolymers, in particular with sulfopolymers, leads to the formation of second phases with insensitive surfaces. Corresponding surfaces can be touched by the end user without material sticking to their hands. There is also no material removal in packaging. The second phase therefore preferably comprises gelatin and an anionic copolymer / polymer. The proportion of the anionic polymer is preferably 1% by weight to 35% by weight, in particular 3% by weight to 30% by weight, especially 5% by weight to 25% by weight, preferably 5% by weight % to 20% by weight based on the total weight of the second phase. Sulphopolymers also ensure an excellent surface gloss. In addition, fingerprints are not retained. The proportion of sulfopolymers, especially sulfopolymers with AMPS as the monomer containing sulfonic acid groups, for example Acusol 590, Acusol 588 or Sokalan CP50, is preferably 1% by weight to 25% by weight, in particular 3% by weight to 15% by weight. %, especially 4% by weight to 12% by weight, preferably 5% by weight to 10% by weight, based on the weight of the second phase. In a particularly preferred embodiment, the at least one second phase therefore comprises gelatin and a sulfopolymer and at least one polyhydric alcohol.

According to the invention, the at least one second phase can furthermore comprise thickening polymer. It is preferably a polycarboxylate. Used as a polycarboxylate preferably a copolymeric polyacrylate, preferably a sulfopolymer, preferably a copolymeric polysulfonate, preferably a hydrophobically modified copolymeric polysulfonate.

The unsaturated dicarboxylic acids can of course also be used.

In the case of monomers containing sulfonic acid groups, preference is given to those of the formula R ⁵ (R ⁶ ) C =C (R ⁷ ) -X-SO ₃ H, in which R ⁵ to R ^7, independently of one another, represent -H, -CH ₃ , a straight-chain or branched, saturated alkyl radical with 2 to 12 carbon atoms, a straight-chain or branched, mono- or polyunsaturated alkenyl radical with 2 to 12 carbon atoms, alkyl or alkenyl radicals substituted with - NH ₂ , --OH or --COOH or for --COOH or --COOR ⁴ where R ^{4 is} a saturated or unsaturated, straight-chain or branched hydrocarbon radical having 1 to 12 carbon atoms, and X is an optionally present spacer group which is selected from - (CH ₂ ) _n - with n = 0 to 4, -COO - (CH ₂ ) _k - with k = 1 to 6, -C (O) -NH-C (CH ₃ ) ₂ -, - C (O) -NH-C (CH ₃ ) ₂ -CH ₂ - and - C (O) -NH-CH (CH ₃ ) -CH ₂ -.

In the polymers, the sulfonic acid groups can be wholly or partly in neutralized form, which means that the acidic hydrogen atom of the sulfonic acid group in some or all sulfonic acid groups can be exchanged for metal ions, preferably alkali metal ions and in particular for sodium ions. The use of partially or fully neutralized copolymers containing sulfonic acid groups is preferred according to the invention.

The monomer distribution of the copolymers preferably used according to the invention is, in the case of copolymers which only contain monomers containing carboxylic acid groups and monomers containing sulfonic acid groups, preferably in each case from 5 to 95% by weight; the proportion of the monomer containing sulphonic acid groups is particularly preferably 50 to 90% by weight. % and the proportion of the carboxylic acid group-containing monomer 10 to 50% by weight, the monomers here are preferably selected from those mentioned above.

In a further preferred embodiment, the copolymers furthermore comprise at least one nonionic, preferably hydrophobic, monomer in addition to monomer containing carboxyl groups and monomer containing sulfonic acid groups. The use of these hydrophobically modified polymers made it possible in particular to improve the rinse aid performance of dishwashing detergents according to the invention.

1. i) monomers containing carboxylic acid groups
2. ii) Monomers containing sulfonic acid groups
3. iii) nonionic monomers, in particular hydrophobic monomers, are used.

The nonionic monomers used are preferably monomers of the general formula R ¹ (R ² ) C =C (R ³ ) -XR ⁴ , in which R ¹ to R ³ independently of one another represent -H, -CH ₃ or -C ₂ H ₅ , X stands for an optionally present spacer group which is selected from -CH ₂ -, - C (O) O- and -C (O) -NH-, and R ^{4 stands} for a straight-chain or branched, saturated alkyl radical having 2 to 22 carbon atoms or represents an unsaturated, preferably aromatic radical having 6 to 22 carbon atoms.

According to the invention, the at least one second phase can also contain further polymers, such as PEG, in particular those polyethylene glycols with an average molecular weight between about 200 and 8000, between about 800 and 4000 g / mol, particularly preferably with an average molecular weight between 1000 and 2000 g / mol , for example around 1500 g / mol (INCI: PEG1500), which increase the stability of the second phase.

The at least one second phase comprises at least one polyhydric alcohol. The at least one polyhydric alcohol enables a dimensionally stable, non-flowable second phase to be produced within a short solidification time of 15 minutes or less, in particular of 10 minutes or less. For the purposes of the present invention, polyhydric alcohols are hydrocarbons in which two, three or more hydrogen atoms have been replaced by OH groups. The OH groups are bound to different carbon atoms. A carbon atom does not have two OH groups. This is in contrast to (simple) Alcohols in which only one hydrogen atom in hydrocarbons has been replaced by an OH group. Polyhydric alcohols with two OH groups are called alkanediols, polyhydric alcohols with three OH groups are called alkanediols. A polyhydric alcohol thus corresponds to the general formula [KW] (OH) _x , where KW stands for a hydrocarbon that is linear or branched, saturated or unsaturated, substituted or unsubstituted. Substitution can take place, for example, with — SH or —NH groups. KW is preferably a linear or branched, saturated or unsaturated, unsubstituted hydrocarbon. KW comprises at least two carbon atoms. The polyhydric alcohol comprises 2, 3 or more OH groups (x = 2, 3, 4 ...), with only one OH group being bonded to each carbon atom of the HC. KW particularly preferably comprises 2 to 10, that is 2, 3, 4, 5, 6, 7, 8, 9 or 10 carbon atoms. In particular, polyhydric alcohols with x = 2, 3 or 4 (for example pentaerythritol with x = 4) can be used. Preferably x = 2 (alkanediol) and / or x = 3 (alkanetriol).

The at least one second phase particularly preferably comprises at least one alkanetriol and / or at least one alkanediol, in particular at least one C ₃ to C ₁₀ alkanediol and / or at least one C ₃ to C ₁₀ alkanediol, preferably at least one C ₃ to C ₈ alkanetriol and / or at least one C ₃ to C ₈ alkanediol, especially at least one C ₃ to C ₆ alkanetriol and / or at least one C ₃ to C ₅ alkanediol, as a polyhydric alcohol. It preferably comprises an alkanetriol and an alkanediol as at least one polyhydric alcohol. In a preferred embodiment, the at least second phase therefore comprises at least one polymer, in particular gelatin and / or PVA, and at least one alkanediol and at least one alkanetriol, in particular an alkanetriol and an alkanediol. Likewise preferred is a second phase which comprises at least one polymer, in particular gelatin and / or PVA, as well as a C ₃ to C ₈ alkanediol and a C ₃ to C ₈ alkanetriol. A second phase is further preferred, which comprises at least one polymer, in particular gelatin and / or PVA, as well as a C ₃ to C ₅ alkanediol and a C ₃ to C ₆ alkanetriol.

Surprisingly, it has been found that when a corresponding triol (alkanediol) is combined with a corresponding diol (alkanediol), particularly short solidification times can be achieved. The second phases obtained are also transparent and have a glossy surface, which ensures an appealing visual impression of the washing or cleaning agent according to the invention. The terms diol and alkanediol are used synonymously here. The same applies to triol and alkanetriol.

According to the invention, the polyhydric alcohols do not include any derivatives such as ethers, esters, etc. thereof.

The amount of polyhydric alcohol or polyhydric alcohols used in the second phases according to the invention is preferably at least 45% by weight, in particular 55% by weight or more. Preferred quantity ranges here are from 5% by weight to 75% by weight, in particular from 10% by weight to 70% by weight, based on the total weight of the second phase.

The C ₃ - to C ₆ -alkanetriol is preferably glycerol and / or 2-ethyl-2- (hydroxymethyl) -1,3-propanediol (also called 1,1,1-trimethylolpropane) and / or 2-amino-2- (hydroxymethyl) -1,3-propanediol (TRIS, trishydroxymethylaminoethane).

The C ₃ to C ₆ alkanetriol glycerol and / or 2-ethyl-2- (hydroxymethyl) -1,3-propanediol (also called 1,1,1-trimethylolpropane) is particularly preferred. The C ₃ - to C ₅ - alkanediol is preferably 1,3-propanediol and / or 1,2-propanediol. Surprisingly, it has been shown that the chain length of the diol and, in particular, the position of the OH groups has an influence on the transparency of the second phase. The OH groups of the diol are therefore preferably not arranged on directly adjacent carbon atoms. In particular, there are three or four carbon atoms, in particular 3 carbon atoms, between the two OH groups of the diol. The diol 1,3-propanediol is particularly preferred. It has surprisingly been found that particularly good results are achieved with mixtures which comprise glycerol and 1,3-propanediol and / or 1,2-propanediol. The second phase particularly preferably comprises gelatin, glycerol and 1,3-propanediol or gelatin, 1,1,1-trimethylolpropane and 1,3-propanediol. Here, within a solidification time of 10 minutes or less, a non-flowable consistency which is dimensionally stable at room temperature and which remains dimensionally stable even after a long storage period can be achieved. In addition, a corresponding phase is transparent and has a shiny surface. A particularly preferred second phase therefore comprises gelatin or PVA as the polymer and 1,3-propanediol and glycerol or 1,1,1-trimethylolpropane as polyhydric alcohols.

If the second phase comprises an alkanetriol, in particular glycerol or 1,1,1-trimethylolpropane, the proportion of alkanetriol, in particular glycerol or 1,1,1-trimethylolpropane, based on the total weight of the second phase, is preferably 5% by weight up to 70% by weight, in particular 10% by weight to 65% by weight, especially 20% by weight to 40% by weight.

If the second phase optionally comprises several alkanetriol (s), the total proportion of alkanetriol (s), based on the total weight of the second phase, is preferably 5% by weight to 70% by weight, in particular 10% by weight to 65% by weight, especially 20% by weight to 40% by weight.

If glycerol is contained in the second phase as alkanetriol, the proportion of glycerol based on the total weight of the second phase is preferably 5% by weight to 70% by weight, in particular 10% by weight to 65% by weight, especially 20 wt% to 40 wt%.

At least one first and / or second phase according to the invention preferably contain at least one nonionic surfactant. All nonionic surfactants known to the person 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. These are specified in more detail below.

Suitable nonionic surfactants are, for example, alkyl glycosides of the general formula RO (G) _x in which R corresponds to a primary straight-chain or methyl-branched, in particular methyl-branched aliphatic radical with 8 to 22, preferably 12 to 18 carbon atoms and G is the symbol , which stands for a glycose unit with 5 or 6 carbon atoms, preferably for glucose.

The amount of these nonionic surfactants is preferably not more than that of the ethoxylated fatty alcohols, in particular not more than half that.

Further suitable surfactants are the polyhydroxy fatty acid amides known as PHFA.

In particular, however, alcohol ethoxylates with linear radicals of alcohols of native origin with 12 to 18 carbon atoms, for example from coconut, palm, tallow or oleyl alcohol, and an average of 2 to 8 moles of EO per mole of alcohol are preferred. The preferred ethoxylated alcohols include, for example, C _12-14 alcohols with 3 EO or 4 EO, C _8-11 alcohol with 7 EO, C _13-15 alcohols with 3 EO, 5 EO, 7 EO or 8 EO, C _12-18 alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of C _12-14 alcohol with 3 EO and C _12-18 alcohol with 5 EO.

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 are tallow fatty alcohol with 14 EO, 25 EO, 30 EO or 40 EO.

Ethoxylated nonionic surfactants, which are composed of C _6-20 monohydroxyalkanols or C _6-20 alkylphenols or C _16-20 fatty alcohols and more than 12 moles, preferably more than 15 moles and in particular more than 20 moles of ethylene oxide per mole of alcohol, are particularly preferred were obtained. A particularly preferred nonionic surfactant is obtained from a straight-chain fatty alcohol with 16 to 20 carbon atoms (C _16-20 alcohol), preferably a C ₁₈ alcohol and at least 12 mol, preferably at least 15 mol and in particular at least 20 mol 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) non-ionic surfactants are also characterized by good foam control.

If native sources are used, the radical R ^{1 has} an even number of carbon atoms and is usually unbranched, the linear radicals from alcohols of native origin with 12 to 18 carbon atoms, for example from coconut, palm, tallow fat or Oleyl alcohol, are preferred. Alcohols accessible from synthetic sources are, for example, the Guerbet alcohols or radicals which are methyl-branched in the 2-position or linear and methyl-branched radicals in a mixture, as are usually present in oxo alcohol radicals.

The specified carbon chain lengths and degrees of ethoxylation or degrees of alkoxylation of the nonionic surfactants represent statistical mean values which, for a specific product, can be an integer or a fraction.

Substances that also serve as ingredients of cosmetic agents are referred to below, where appropriate, according to the International Nomenclature Cosmetic Ingredient (INCI) nomenclature. Chemical compounds have an INCI name in English. The INCI names can be found in the "International Cosmetic Ingredient Dictionary and Handbook, 7th Edition (1997)" published by The Cosmetic, Toiletry and Fragrance Association (CTFA), Washington D.C.

In higher amounts, the sugar does not dissolve completely in the second phase and leads to cloudiness. The use of sugar, in particular in a proportion of 10% by weight to 15% by weight, reduces the development of moisture and thus improves the adhesion to at least one first phase.

The use of builders (builders) such as silicates, aluminum silicates (especially zeolites), salts of organic di- and polycarboxylic acids and mixtures of these substances, preferably water-soluble builders, can be advantageous.

A protein and / or enzyme can be protected against damage such as inactivation, denaturation or disintegration, 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, in particular if the agents also contain proteases. Cleaning agents can contain stabilizers for this purpose; the provision of such means represents a preferred embodiment of the present invention.

Additional active ingredients, for example stabilizers, emulsifiers, pigments, bleaches 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. Such granules are advantageously low in dust, for example due to the application of polymeric film formers, and due to the coating are stable in storage.

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

Mixtures with surfactant or polymer additives show synergisms in the case of Tegopren® 5843 and Tegopren® 5863. The use of the Tegopren types 5843 and 5863 is, however, less preferred for use on hard surfaces made of glass, in particular glass dishes, because these silicone surfactants can be absorbed onto glass. In a particular embodiment of the invention, the additives mentioned are dispensed with.

A preferred washing or cleaning agent, in particular dishwashing detergent, preferably further comprises a bleaching agent, in particular an oxygen bleaching agent and optionally a bleach activator and / or bleach catalyst. If available, these are only included in the at least one first phase.

The washing or cleaning agent according to the invention comprises at least a first phase (1) and at least a second phase (2). The washing or cleaning agent can thus have one, two, three or more different first phases (1); it can also have one, two, three or more different second phases (2). The washing or cleaning agent according to the invention preferably comprises a first phase (1) and a second phase (2). The washing or cleaning agent particularly preferably comprises two first phases (1) and a second phase (2). It preferably comprises two first phases (1) and two second phases (2). Also preferred is an embodiment in which the detergent or cleaning agent comprises three first phases (1) and one or two second phases (2). The weight ratio of the at least one first phase (1) to the at least one second phase (2) is preferably 20: 1 to 8: 1. The total weight of phase (1) in a cleaning agent portion can be between 8 and 30 g, in particular 10 to 25 g, preferably 12 to 21 g, for example 14 to 19 g. This weight ratio results in a good concentration of the respective ingredients of the first (1) or second phase (2) in one cleaning process.

According to the invention, the at least one first phase (1) and the at least one second phase (2) adjoin one another over the full or partial area. It is preferred that the two phases directly adjoin one another. However, it is also possible that the at least one first phase (1) or the at least one second phase (2) or the at least one first phase (1) and the at least one second phase (2) are closely wrapped in a water-soluble film or in one water-soluble pouch is / are included. The entire agent is preferably contained in a water-soluble bag or, particularly preferably, is tightly enclosed by a water-soluble film.

If the at least one first phase (1) and the at least one second phase (2) border one another over the full or partial area, stability is important in addition to the shortest possible solidification time of the at least one second phase (2). Stability here means that components contained in the second phase do not pass into the at least one first phase, but also after prolonged storage the at least one first phase and the second phase are optically separate from one another and do not interact with one another, such as diffusion of liquid components from one phase to the other or reaction of components of one phase with those in the other phase or Loss of adhesion of the second phase (2) on the in particular compressed, compacted first phase (1) due to the leakage of liquid. Surprisingly, it has been shown that this can be made possible by a second phase comprising glycerine, gelatin and at least one C ₃ - to C ₅ -alkanediol.

The water-soluble film or the water-soluble bag preferably comprises a water-soluble polymer. Some preferred water-soluble polymers, which are preferably used as water-soluble packaging, are polyvinyl alcohols, acetalized polyvinyl alcohols, polyvinylpyrrolidones, polyethylene oxides, celluloses and gelatin, with polyvinyl alcohols and acetalized polyvinyl alcohols being particularly preferred.

die in geringen Anteilen (ca. 2%) auch Struktureinheiten des Typs enthalten.

"Polyvinyl alcohols" (abbreviation PVAL, occasionally also PVOH) is the name for polymers with the general structure

which also contain structural units of the type in small proportions (approx. 2%).

Commercially available polyvinyl alcohols, which are offered as white-yellowish powders or granules with degrees of polymerization in the range from approx. 100 to 2500 (molar masses from approx. 4000 to 100,000 g / mol), have degrees of hydrolysis of 87-99 mol%, i.e. they contain one more Residual content of acetyl groups.

In the context of the present invention, it is preferred that the water-soluble packaging at least partially comprises a polyvinyl alcohol whose degree of hydrolysis is preferably 70 to 100 mol%, in particular 80 to 90 mol%, particularly preferably 81 to 89 mol% and above all 82 to Is 88 mole percent. In a preferred embodiment, the water-soluble packaging consists of at least 20% by weight, particularly preferably at least 40% by weight, very particularly preferably at least 60% by weight and in particular at least 80% by weight 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%.

Polyvinyl alcohols of a certain molecular weight range are preferably used as materials for the packaging, it being preferred according to the invention that the packaging material comprises a polyvinyl alcohol whose molecular weight is in the range from 5,000 g mol ^-1 to 100,000 g mol ^-1 , preferably from 10,000 g mol ^-1 to 90,000 g mol ^-1 , particularly preferably from 12,000 g mol ^-1 to 80,000 g mol ^-1 and in particular from 15,000 g mol ^-1 to 70,000 g mol ^-1 .

The degree of polymerization of such preferred polyvinyl alcohols is between about 200 to about 2100, preferably between about 220 to about 1890, particularly preferably between about 240 to about 1680 and in particular between about 260 to about 1500.

The water solubility of polyvinyl alcohol can be changed by post-treatment with aldehydes (acetalization) or ketones (ketalization). 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 cold water solubility. The reaction products of polyvinyl alcohol and starch are extremely advantageous. Furthermore, the water solubility can be changed by complexing with Ni or Cu salts or by treatment with dichromates, boric acid, borax and thus set to the desired values in a targeted manner.

The water-soluble bag is preferably from 10 μm to 500 μm, in particular from 20 μm to 400 μm, particularly preferably from 30 μm to 300 μm, especially from 40 μm to 200 μm, in particular from 50 μm to 150 μm. A particularly preferred polyvinyl alcohol is available, for example, under the trade name M8630 (Monosol).

The water-soluble film, which is preferably used in the tight envelope), particularly preferably comprises polyvinyl alcohol, as described above, the starting thickness preferably being from 10 μm to 100 μm, in particular from 12 μm to 60 μm, particularly preferably from 15 μm to 50 µm, in particular from 20 µm to 40 µm, in particular from 22 µm to 35 µm, is used.

In the case of a tight envelope, a single portion of the detergent or cleaning agent is coated in each case. For the coated washing or cleaning agent single portion according to the invention, it is important that the coating lies tightly against the surface of the tablets at every point. Ideally, the envelope is even under tension, but this is not absolutely necessary. This tight fit of the cover is conducive to disintegration: the first time it comes into contact with water, a small amount of water will let through at some point, and it does not have to come off at first. At this point the disintegrant contained in the tablet begins to swell. As a result of the increase in volume of the tablet, the envelope now suddenly tears open and the tablet is released. The mechanism described here does not work if the casing is not tightly fitting, since the tablet can swell without the casing being ruptured as a result. The use of a swellable disintegrant is superior to a gas-generating system, since its disintegrating effect always leads to the covering being torn open. In the case of a gas-generating system, the explosive effect can "fizzle out" as the gas escapes from a leak in the casing.

Preferred washing or cleaning agent single portions according to the invention are characterized in that the distance between the single portion and the water-soluble cover over the entire surface is 0.1 to 1000 μm, preferably 0.5 to 500 μm, particularly preferably 1 to 250 μm and in particular 2.5 to 100 µm.

In a preferred embodiment, the film envelope is first placed loosely around a single portion of detergent or cleaning agent and welded and then shrunk onto it, so that there is close contact between the film packaging and the cleaning agent concentrate. Accordingly, one-time washing or cleaning agent portions according to the invention are characterized in that the cover is a film packaging shrunk onto it.

For example, this wrapping can take place in that a water-soluble lower film is placed on a transport chain or a mold (s), then one or more detergent or cleaning agent portions are placed on the lower film; then a water-soluble upper film is placed on the detergent or cleaning agent portion (s) on the lower film and this is then fixed on the lower film, including the washing or cleaning agent portion (s). Alternatively, this step can also be carried out by a single-strand film, which is then used as Tubing around the disposable portions. This is followed by sealing and optional cutting of the foils. Then the film can then be shrunk on using hot air or infrared radiation, optionally with pressure applied.

Such water-soluble coatings are also in the patent applications WO 2004/031338 A as WO 2003/099985 A , the disclosure of which is hereby incorporated by reference in its entirety, already described.

The at least one first phase (1) of the washing or cleaning agent according to the invention, in particular the dishwashing detergent, preferably the automatic dishwashing detergent, is in a preferred embodiment in the form of a shaped body, in particular a compact, especially a tablet. The at least one first phase (1) is particularly preferably a powdered detergent or cleaning agent which is compacted in the form of a tablet.

The at least one first phase (1) and the at least one second phase (2) can be arranged in any combination with one another, regardless of whether they are directly or indirectly (for example through the presence of a film, envelope or bag as described above). A first phase (1) can be arranged on or next to a second phase (2), as in FIG Fig. 1 shown schematically. In this embodiment, the washing or cleaning agent according to the invention has a first phase (1) and a second phase (2). It is also conceivable that a first phase (1) is surrounded by second phases (2), or vice versa, as in FIG Figures 2a and 2b shown. Also embedding one phase in another, as in Figures 3a and 3b shown schematically, is included according to the invention. Another particularly preferred arrangement is shown in FIG Fig. 4 shown schematically. The second phase (2) is in the form of a core that is embedded in the first phase (1). A pool shape of the solid first phase (1), that is to say a shape with a trough into which the second phase is introduced, is particularly preferred. The trough can be round, oval or square. There may also be two separate troughs that are filled with the at least one second phase (2). In this embodiment, the washing or cleaning agent comprises two second phases (2), it being possible for the two second phases to have different compositions.

In principle, any geometries are possible. The rectangular shape shown here is only an example. A round or oval shape of the two phases or any polygonal configurations are also conceivable.

Another object of the present application is a method for cleaning hard surfaces, in particular dishes, in which the surface is processed in a manner known per se using a cleaning agent according to the invention. In particular, the surface is brought into contact with the washing or cleaning agent according to the invention. The cleaning takes place in particular with a cleaning machine, preferably with a dishwasher.

The present invention also relates to the use of a cleaning agent for cleaning hard surfaces, in particular dishes.

In a preferred embodiment, the present application relates to automatic dishwashing detergents. In accordance with this application, automatic dishwashing agents are compositions which can be used to clean soiled dishes in an automatic dishwashing process. The automatic dishwashing agents according to the invention thus differ, for example, from the automatic rinse aid agents, which are always used in combination with automatic dishwashing agents and do not develop their own cleaning effect.

Insofar as it is stated in the present application that the washing or cleaning agent according to the invention comprises something in its entirety or in the at least one first phase (1) or in the at least one second phase (2), it is also to be regarded as disclosed that washing or Cleaning agent or the respective phase can consist of it. In the exemplary embodiment below, the inventive washing or cleaning agent is described in a non-limiting manner.

Embodiments:

Cleaning agents according to the invention were produced which comprised a first phase and a second phase. Different geometries were implemented here. In addition, cleaning agents were produced which comprised two first phases and a second phase. The following information relates to% by weight of active substance based on the total weight of the respective phase.

The first phases had the following composition: Wt% Citrate, sodium salt 10-25 Phosphonate (e.g. HEDP) 0-10 MGDA, sodium salt 0-40 Disilicate, sodium salt 0-40 soda 10-30 Percarbonate, sodium salt 5.0-20.0 Bleach catalyst (preferably Mn-based) 0.0-0.8 Bleach activator (e.g. TAED) 1.0-4.0 Nonionic surfactant (s), for example fatty alcohol alkoxylate, preferably 20-40 EO, optionally endcapped 1.5-15.0 Polycarboxylate 0.5-15 Cationic copolymer 0.0-1.0 Disintegrant - (e.g. Crosslinked PVP) 0.0-3.0 Protease preparation (tq) 1.0-7 Amylase preparation (tq) 0.2- 6 Silver protection (benzotriazole) 0.0 - 1.0 Perfume 0.0-0.5 Dye solution 0.0 - 1.5 Zn salt (e.g. acetate) 0.01-0.5 Sodium sulfate 0.0 - 25 water 0.0-3 pH adjusting agent (e.g. citric acid) 0.0 - 5 Process aids 0-10

Furthermore, the first phases were produced, which had the following composition: Wt% Citrate, sodium salt 15-20 Phosphonate (e.g. HEDP) 2.5-7.5 MGDA, sodium salt 0-25 Disilicate, sodium salt 5-35 soda 10-25 Percarbonate, sodium salt 10-15 Bleach catalyst (preferably Mn-based) 0.02-0.5 Bleach activator (e.g. TAED) 1-3 Nonionic surfactant (s), for example fatty alcohol alkoxylate, preferably 20-40 EO, optionally endcapped 2.5-10 Polycarboxylate 4-10 Cationic copolymer 0-0.75 Disintegrant - (e.g. Crosslinked PVP) 0-1.5 Protease preparation (tq) 1.5-5 Amylase preparation (tq) 0.5-3 Silver protection (benzotriazole) 0-0.5 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

These first phases were in the form of a compacted tablet with a depression on one side. A liquid composition was poured into this which, after hardening, resulted in the second phase. The detergent obtained was in accordance with the in Fig. 4 shown form. There were other first phases without any specialization. Here, a second phase was brought into direct contact on the surface of the first phase.

The second phases had the following composition: Wt% Glycerin 10-50 Propanediol (preferably 1,3-propanediol) 10-50 Polycarboxylate homo- and / or copolymer with sulfonic acid-containing groups 0-30 Nonionic surfactant (s), for example fatty alcohol alkoxylate, preferably 20-40 EO, optionally endcapped 0-40 Polyethylene glycol medium Mr 1000-2000 0-20 Thickener (preferably gelatin or PVA) 5-50 Process aids 0-10 Dye solution 0.0 -1.5

Further second phases with the following composition were produced: Wt% Glycerin 20 - 45 Propanediol (preferably 1,3-propanediol) 10-30 Polycarboxylate; Homo- and / or copolymer with groups containing sulfonic acids 5-20 Nonionic surfactant (s), for example fatty alcohol alkoxylate, preferably 20-40 EO, optionally endcapped 5-25 Polyethylene glycol medium Mr 1000-2000 0 - 8 Thickener (preferably gelatin or PVA) 10-20 Process aids 0-5 Dye solution 0.0-0.5

The first and second phases could be combined with one another as required. The spatial design of the second phase, which was liquid after the ingredients were mixed and dimensionally stable within a solidification time of about 10 to 15 minutes, was given by the spatial design of the first phase and by customary or self-designed shapes. The liquid second phase was introduced into these molds and, after the solidification time, the molds were removed without the second phase changing. This enabled any desired geometries for the second phase. Table 1: Examples of compositions of a second phase A1 A2 1,2 propanediol 0.0 31 1.3 propanediol 31 0.0 Trisodium Citrate * 2 H ₂ O 8th 8th Glycerin 31 31 Gelatin 60 Bloom 15th 15th Nonionic surfactant 15th 15th Solidification time (20 ° C) / min 5 20th Surface feel after 12 h storage at 20 ° C dry wet

From Table 1 it can be seen that 1,3 propanediol leads to a more rapid solidification of the dimensionally stable second phase.
