Description

The invention relates to a combination of fatty acid and or its salts and (meth) acrylic acid (co) polymer in detergents or cleaners containing surfactant (s) and other conventional ingredients of detergents or cleaners.

Liquid detergents or cleaners are often offered in thickened form and contain a thickener or a thickener system.

The thickening effect of known thickeners or thickener systems depends, on the one hand, on the other ingredients of the washing or cleaning agent to be thickened, such as, for example, the surfactants, electrolytes, solvents or perfume oils. Furthermore, the pH of the detergent or cleaning agent to be thickened can have a great influence on the thickening effect.

Frequently used thickeners are polyacrylate thickeners. These show in liquid detergents or cleaners at a pH in the range of 8 to 9, the best thickening effect. In this pH range, however, there are very large fluctuations in the viscosity of the liquid detergents or cleaners, which can be up to 1000 mPas. Such large fluctuations are extremely undesirable in terms of production technology.

The viscosity of detergents or cleaning agents containing fatty acid soap can be increased within certain limits by lowering the pH. However, larger amounts of unsaponified fatty acid can lead to cloudiness and instability.

From the US 6,342,472 B1 Thickened fatty acid soap-containing detergents or cleaners are known which comprise at least 0.5% by weight of a polyacrylate thickener and 13% by weight of a fatty acid salt.

1. (a) 0,1 bis weniger als 5 Gew.-% einer Fettsäure und/oder eines Fettsäuresalzes und
2. (b) 0,01 bis weniger als 0,5 Gew.-% eines (Meth)Acrylsäure(co)polymers zur Reduzierung von Viskositäts schwankungen eines flüssigen Wasch- und Reinigungsmittells, welches Tensid(e) und weitere üblidre Inhaltsstoffe von Wasch- und Reiningungsmitteln enthält.

It is an object of the invention to provide a thickened detergent or cleaning agent which is stable and / or has a relatively constant viscosity over a wide pH range. This task is solved by the use of a combination of

1. (a) 0.1% to less than 5% by weight of a fatty acid and / or a fatty acid salt and
2. (B) from 0.01 to less than 0.5 wt .-% of a (meth) acrylic acid (co) polymer for reducing viscosity fluctuations of a liquid detergent and cleaning agent, which surfactant (s) and ü ü ü ü other üblidre ingredients of washing and Contains cleaning agents.

Surprisingly, it has been shown that a significant reduction in the content of fatty acid and / or fatty acid salt in combination with extremely small amounts of (meth) acrylic acid (co) polymer leads to detergents or cleaners whose viscosity is sufficiently high and with variation of the pH fluctuates only to a small extent. Furthermore, the washing or cleaning agents are stable and show no precipitation, turbidity or the like.

It is preferred that the amount of fatty acid and / or fatty acid salt is between 0.5 and 3% by weight and more preferably between 0.75 and 1.5% by weight.

It has been shown that by lowering the amount of fatty acid and / or fatty acid salt, the viscosity fluctuations are significantly lower with variation of the pH, without the secondary washing performance, such as the anti-graying effect of the detergent or cleaning agent is reduced.

It is further preferred that the amount of (meth) acrylic acid (co) polymer is between 0.01 and 0.3% by weight.

These small amounts of (meth) acrylic acid (co) polymer are sufficient to also stabilize the detergent or cleaner against phase separation, clouding or flocculation. Furthermore, overall the manufacturing costs for the washing or cleaning agent can be reduced by the lower raw material costs for the polyacrylate.

It is further preferred that the washing or cleaning agent further contains 0.001 to 3 wt .-% of a silicone compound.

Detergents or cleaners often contain silicone compounds, especially as foam inhibitors. Particularly surprisingly, it has been found that the small amounts of (meth) acrylic acid (co) polymer in combination with the selected amounts of fatty acid and / or fatty acid salt liquid detergents and cleaners with a silicone compound against precipitation of the silicone compound, for example in the form of clouds, Flakes or specks, stabilize.

In a preferred embodiment, the washing or cleaning agent contains 0.01 to 5 wt .-% of a perfume. The selected amounts of fatty acid and / or fatty acid salt in combination with the small amounts of (meth) acrylic acid (co) polymer lead to liquid detergents or cleaners. in which the perfume has a significantly reduced influence on the viscosity.

Particularly stable detergents or cleaners with low viscosity fluctuations with variation of the pH value can also be obtained if the washing or cleaning agent contains, in addition to the combination of fatty acid (salt) and (meth) acrylic acid (co) polymer, 0.1 to 15 wt. - contains% glycerin.

Disclosed is also a process for the preparation of a washing or cleaning agent with reduced viscosity fluctuations, containing surfactant (s) and other common ingredients of detergents or cleaners, wherein the agent (a) 0.1 to less than 5 wt .-% of a fatty acid and / or a fatty acid salt and (b) from 0.01 to less than 0.5% by weight of a (meth) acrylic acid (co) polymer. A washing or cleaning agent produced in this way shows reduced viscosity fluctuations in particular in the case of variation of the pH of the washing or cleaning agent in the range from 7 to 9.

A further aspect relates to the use of the washing or cleaning agent for washing and / or cleaning textile fabrics.

The invention relates to the use of a combination of (a) 0.1 to less than 5 wt .-% of a fatty acid and / or a fatty acid salt and (b) 0.01 to less than 0.5 wt .-% of a (meth) Acrylic acid (co) polymer for reducing viscosity fluctuations of a liquid detergent or cleaning agent containing surfactant (s) and other common ingredients of detergents or cleaners. Particularly effective is the variation in viscosity with a variation of the pH of the liquid detergent or cleaning agent in the range of 7 to 9 is reduced.

In addition, the invention relates to the use of a combination of (a) 0.1 to less than 5 wt .-% of a fatty acid and / or a fatty acid salt and (b) 0.01 to less than 0.5 wt .-% of a (meth Acrylic acid (co) polymer for stabilizing a liquid washing or cleaning agent, which contains surfactant (s), a silicone compound and other common ingredients of detergents or cleaners.

2. (b) 0.01 to less than 0.5% by weight of a (meth) acrylic acid (co) polymer.

As an essential ingredient, liquid detergents or cleaners contain a fatty acid and / or a fatty acid salt. Suitable are saturated and unsaturated fatty acids, such as lauric acid, myristic acid, palmitic acid, stearic acid, (hydrogenated) erucic acid and behenic acid and in particular from natural fatty acids, for example coconut, palm kernel, olive oil or tallow, derived mixtures and their salts.

The fatty acid salts may be in the form of their sodium, potassium or ammonium salts and as soluble salts of organic bases, such as mono-, di- or triethanolamine. The fatty acid salts are preferably present in the form of their sodium or potassium salts, in particular in the form of the sodium salts.

The amount of fatty acid and / or fatty acid salt is from 0.1 to less than 5 wt%, preferably between 0.25 and 4 wt%, more preferably between 0.5 and 3 wt%, more preferably between 0.6 and 2 wt .-% and even more preferably between 0.75 and 1.5 wt .-%, each based on the total agent.

In addition to the fatty acid and / or the fatty acid salt, a washing or cleaning agent necessarily contains 0.01 to less than 0.5 wt .-% of a (meth) acrylic acid (co) polymer. Suitable acrylic and methacrylic (co) polymers include, for example, the high molecular weight homopolymers of acrylic acid crosslinked with a polyalkenyl polyether, in particular an allyl ether of sucrose, pentaerythritol or propylene (INCI name according to "International Dictionary of Cosmetic Ingredients" of "The Cosmetic, Toiletry and Fragrance Association (CTFA) ": carbomer), also referred to as carboxyvinyl polymers. Such polyacrylic acids are available, inter alia, from the company 3V Sigma under the trade name Polygel®, for example Polygel DA, and from the company BF Goodrich under the trade name Carbopol®, eg Carbopol 940 (molecular weight about 4,000,000), Carbopol 941 ( Molecular weight about 1. 250,000) or Carbopol 934 (molecular weight about 3,000,000). Furthermore, for example, the following acrylic acid copolymers are suitable: (i) copolymers of two or more monomers from the group of acrylic acid, methacrylic acid and their simple, preferably with C _1-4 alkanols formed ester (INCI acrylate copolymer), such as the copolymers of methacrylic acid, butyl acrylate and methyl methacrylate (CAS designation according to Chemical Abstracts Service: 25035-69-2) or of butyl acrylate and methyl methacrylate (CAS 25852-37-3) and the example of the Fa. Rohm & Haas under the trade names Aculyn® and Acusol® and by the company Degussa (Goldschmidt) under the trade name Tego® polymer, for example the anionic non-associating polymers Aculyn 22, Aculyn 28, Aculyn 33 (cross-linked), Acusol 810, Acusol 820, Acusol 823 and Acusol 830 (CAS 25852-37-3); (ii) crosslinked high molecular weight acrylic acid copolymers, such as those crosslinked with an allyl ether of sucrose or pentaerythritol copolymers of C _10-30 alkyl acrylates with one or more monomers selected from the group of acrylic acid, methacrylic acid and their simple, preferably with C _1-4 Alkanols formed, esters (INCI acrylates / C _10-30 alkyl acrylate crosspolymer) include and which are available, for example, from the company.

Further suitable polymers are (meth) acrylic acid (co) polymers of the type Sokalan® (ex BASF), such as, for example, Sokalan® ES 95048.

The amount of (meth) acrylic acid (co) polymer is from 0.01 to less than 0.5% by weight, preferably from 0.01 to 0.3% by weight.

It is preferred that the (meth) acrylic acid (co) polymer is not pure acrylic or methacrylic acid polymers.

The washing or cleaning agent contains, in addition to the fatty acid and / or the fatty acid salt and the (meth) acrylic acid (co) polymer surfactant (s), wherein anionic, nonionic, zwitterionic and / or amphoteric surfactants can be used. Preference is given to mixtures of anionic and nonionic surfactants. The total surfactant content of the liquid washing or cleaning agent is preferably below 40% by weight and more preferably below 35% by weight, based on the total liquid detergent.

The nonionic surfactants used are preferably alkoxylated, advantageously ethoxylated, in particular primary alcohols having preferably 8 to 18 carbon atoms and on average 1 to 12 moles of ethylene oxide (EO) per mole of alcohol, in which the alcohol radical is linear or preferably in the 2-position may be methyl branched or contain linear and methyl-branched radicals in the mixture, as they are usually present in Oxoalkoholresten. In particular, however, alcohol ethoxylates with linear radicals of alcohols of native origin having 12 to 18 carbon atoms, for example of coconut, palm, tallow or oleyl alcohol, and on average 2 to 8 EO per mole of alcohol are preferred. The preferred ethoxylated alcohols include, for example, C _12-14 alcohols with 3 EO, 4 EO or 7 EO, C _9-11 alcohols 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 7 EO. The degrees of ethoxylation given represent statistical means which, for a particular product, may be an integer or a fractional number. 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 include tallow fatty alcohol with 14 EO, 25 EO, 30 EO or 40 EO. Nonionic surfactants containing EO and PO groups together in the molecule can also be used according to the invention. Here, block copolymers with EO-PO block units or PO-EO block units can be used, but also EO-PO-EO copolymers or PO-EO-PO copolymers. Of course, it is also possible to use mixed alkoxylated nonionic surfactants in which EO and PO units are not distributed in blocks, but randomly. Such products are obtainable by simultaneous action of ethylene oxide and propylene oxide on fatty alcohols.

In addition, as further nonionic surfactants and alkyl glycosides of the general formula RO (G) _x can be used in which R is a primary straight-chain or methyl-branched, especially in the 2-position methyl-branched aliphatic radical having 8 to 22, preferably 12 to 18 carbon atoms and G is the symbol which represents a glycose unit having 5 or 6 C atoms, preferably glucose.

Alkyl glycosides are known, mild surfactants.

Another class of preferred nonionic surfactants used either as the sole nonionic surfactant or in combination with other nonionic surfactants are alkoxylated, preferably ethoxylated or ethoxylated and propoxylated fatty acid alkyl esters, preferably having from 1 to 4 carbon atoms in the alkyl chain, especially fatty acid methyl esters.

Nonionic surfactants of the amine oxide type, for example N-cocoalkyl-N, N-dimethyl-amine oxide and N-tallow alkyl-N, N-dihydroxyethylamine oxide, and the fatty acid alkanolamides may also be suitable. The amount of these nonionic surfactants is preferably not more than that of the ethoxylated fatty alcohols, especially not more than half thereof.

[Z] is preferably obtained by reductive amination of a sugar, for example glucose, fructose, maltose, lactose, galactose, mannose or xylose. The N-alkoxy or N-aryloxy substituted Compounds may then be converted to the desired polyhydroxy fatty acid amides by reaction with fatty acid methyl esters in the presence of an alkoxide catalyst.

The content of nonionic surfactants in the washing or cleaning agent is preferably 3 to 30 wt .-%, preferably 6 to 20 wt .-% and in particular 9 to 15 wt .-%, each based on the detergent or cleaning agent.

In addition to the nonionic surfactants, the washing or cleaning agent may also contain anionic surfactants. As anionic surfactants, for example, those of the sulfonate type and sulfates are used. The surfactants of the sulfonate type are preferably C _9-13 -alkylbenzenesulfonates, olefinsulfonates, ie mixtures of alkene and hydroxyalkanesulfonates and disulfonates, as are obtained, for example, from C _12-18 -monoolefins having terminal or internal double bonds by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acid hydrolysis of the sulfonation products into consideration. Also suitable are alkanesulfonates which are obtained from C _12-18 alkanes, for example by sulfochlorination or sulfoxidation with subsequent hydrolysis or neutralization. Likewise suitable are the esters of α-sulfo fatty acids (ester sulfonates), for example the α-sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.

Further suitable anionic surfactants are sulfated fatty acid glycerol esters. Fatty acid glycerol esters are to be understood as meaning the mono-, di- and triesters and mixtures thereof, as obtained in the preparation by esterification of a monoglycerol with 1 to 3 moles of fatty acid or in the transesterification of triglycerides with 0.3 to 2 moles of glycerol. Preferred sulfated fatty acid glycerol esters are the sulfonation products of saturated fatty acids having 6 to 22 carbon atoms, for example caproic acid, caprylic acid, capric acid, myristic acid, lauric acid, palmitic acid, stearic acid or behenic acid.

Alk (en) ylsulfates are the alkali metal salts and in particular the sodium salts of the sulfuric monoesters of C ₁₂ -C ₁₈ fatty alcohols, for example coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or the C ₁₀ -C ₂₀ oxo alcohols and those half-esters of secondary alcohols of these chain lengths are preferred. Also preferred are alk (en) ylsulfates of said chain length, which contain a synthetic, straight-chain alkyl radical produced on a petrochemical basis, which have an analogous degradation behavior as the adequate compounds the basis of oleochemical raw materials. Of washing technology interest, the C ₁₂ -C ₁₆ alkyl sulfates and C ₁₂ -C ₁₅ alkyl sulfates and C ₁₄ -C ₁₅ alkyl sulfates are preferred. 2,3-Alkylsutfate which can be obtained as commercial products from Shell Oil Company under the name DAN ^®, are suitable anionic surfactants.

The sulfuric acid monoesters of straight-chain or branched C _7-21 -alcohols ethoxylated with from 1 to 6 mol of ethylene oxide, such as 2-methyl-branched C _9-11- alcohols having on average 3.5 mol of ethylene oxide (EO) or C _12-18 . Fatty alcohols with 1 to 4 EO are suitable. Due to their high foaming behavior, they are only used in detergents in relatively small amounts, for example in amounts of from 1 to 5% by weight.

Further suitable anionic surfactants are also the salts of alkylsulfosuccinic acid, which are also referred to as sulfosuccinates or as sulfosuccinic acid esters and the monoesters and / or diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and in particular ethoxylated fatty alcohols. Preferred sulfosuccinates contain C _8-18 fatty alcohol residues or mixtures of these. Particularly preferred sulfosuccinates contain a fatty alcohol residue derived from ethoxylated fatty alcohols, which in themselves constitute nonionic surfactants (see description below). Sulfosuccinates, whose fatty alcohol residues are derived from ethoxylated fatty alcohols with a narrow homolog distribution, are again particularly preferred. Likewise, it is also possible to use alk (en) ylsuccinic acid having preferably 8 to 18 carbon atoms in the alk (en) yl chain or salts thereof.

The anionic surfactants can be present in the form of their sodium, potassium or ammonium salts and as soluble salts of organic bases, such as mono-, di- or triethanolamine. The anionic surfactants are preferably present in the form of their sodium or potassium salts, in particular in the form of the sodium salts.

The content of anionic surfactants in a washing or cleaning agent may be from 0.1 to 30% by weight, based on the total washing or cleaning agent.

In addition to the fatty acid and / or the fatty acid, the (meth) acrylic acid (co) polymer and / the surfactant (s), the detergent or cleaning agent may contain other ingredients that the performance and / or aesthetic properties of the detergent or cleaning agent improve further. In the context of the present invention contains the washing or cleaning agent preferably additionally one or more substances from the group of builders, bleaches, enzymes, electrolytes, non-aqueous solvents, pH adjusters, perfumes, perfume carriers, fluorescers, dyes, hydrotopes, foam inhibitors, silicone oils, anti redeposition agents, grayness inhibitors, anti-shrinkage agents, crease inhibitors, color transfer inhibitors, antimicrobial Active ingredients, germicides, fungicides, antioxidants, preservatives, corrosion inhibitors, antistatic agents, bittering agents, ironing auxiliaries, repellents and impregnating agents, swelling and anti-slip agents, plasticizing components and UV absorbers.

Suitable builders which may be present in the washing or cleaning agent are in particular silicates, aluminum silicates (in particular zeolites), carbonates, salts of organic di- and polycarboxylic acids and mixtures of these substances.

Suitable crystalline layered sodium silicates have the general formula NaMSi _x O _{2x + -} H ₂ O, where M is sodium or hydrogen, x is a number from 1.9 to 4 and y is a number from 0 to 20 and preferred values for x 2, 3 or 4 are. Preferred crystalline layered silicates of the formula given are those in which M is sodium and x assumes the values 2 or 3. In particular, both β- and δ-sodium disilicates Na ₂ Si ₂ O ₅ .yH ₂ O are preferred.

It is also possible to use amorphous sodium silicates with a Na ₂ O: SiO ₂ modulus of from 1: 2 to 1: 3.3, preferably from 1: 2 to 1: 2.8 and in particular from 1: 2 to 1: 2.6, which Delayed and have secondary washing properties. The dissolution delay compared with conventional amorphous sodium silicates may have been caused in various ways, for example by surface treatment, compounding, compaction / densification or by overdrying. In the context of this invention, the term "amorphous" is also understood to mean "X-ray amorphous". This means that the silicates do not yield sharp X-ray reflections typical of crystalline substances in X-ray diffraction experiments, but at most one or more maxima of the scattered X-rays which have a width of several degrees of diffraction angle. However, it may well even lead to particularly good builder properties if the silicate particles provide blurred or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline regions of size 10 to a few hundred nm, with values of up to a maximum of 50 nm and in particular up to a maximum of 20 nm being preferred. Particularly preferred are compacted / compacted amorphous silicates, compounded amorphous silicates and overdried X-ray amorphous silicates.

The finely crystalline, synthetic and bound water-containing zeolite used is preferably zeolite A and / or P. As zeolite P, zeolite MAP® (commercial product from Crosfield) is particularly preferred. Also suitable, however, are zeolite X and mixtures of A, X and / or P. Commercially available and preferably usable in the context of the present invention is, for example, a cocrystal of zeolite X and zeolite A (about 80% by weight of zeolite X) which is sold by SASOL under the brand name VEGOBOND AX ^® and by the formula),

nNa ₂ O • (1-n) K ₂ O • Al ₂ O ₃ • (2 - 2.5) SiO ₂ • (3.5-5.5) H ₂ O

n = 0.90 - 1.0

can be described. The zeolite can be used as a spray-dried powder or else as undried, still moist, stabilized suspension of its preparation. In the event that the zeolite is used as a suspension, it may contain minor additions of nonionic surfactants as stabilizers, for example 1 to 3 wt .-%, based on zeolite, of ethoxylated C ₁₂ -C ₁₈ fatty alcohols having 2 to 5 ethylene oxide groups , C ₁₂ -C ₁₄ fatty alcohols having 4 to 5 ethylene oxide groups or ethoxylated isotridecanols. Suitable zeolites have an average particle size of less than 10 μm (volume distribution, measuring method: Coulter Counter) and preferably contain 18 to 22% by weight, in particular 20 to 22% by weight, of bound water.

Of course, a use of the well-known phosphates as builders is possible, unless such use should not be avoided for environmental reasons. Particularly suitable are the sodium salts of orthophosphates, pyrophosphates and in particular tripolyphosphates.

Organic builders which may be present in the washing or cleaning agent are, for example, the polycarboxylic acids which can be used in the form of their sodium salts, polycarboxylic acids meaning those carboxylic acids which carry more than one acid function. These are, for example, citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, sugar acids, aminocarboxylic acids, nitrilotriacetic acid (NTA) and their derivatives and mixtures thereof. Preferred salts are the salts of polycarboxylic acids such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures thereof.

The acids themselves can also be used. In addition to their builder effect, the acids also typically have the property of an acidifying component and thus also serve to set a lower and milder pH of detergents or cleaners. In particular, citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any desired mixtures of these can be mentioned here. Other known pH regulators such as sodium bicarbonate and Natriumhydrogensutfat.

As builders further polymeric polycarboxylates are suitable. These are, for example, the alkali metal salts of polyacrylic acid or polymethacrylic acid, for example those having a molecular weight of 500 to 70,000 g / mol.

For the purposes of this document, the molecular weights stated for polymeric polycarboxylates are weight-average molar masses M _{w of} the particular acid form, which were determined in principle by means of gel permeation chromatography (GPC), a UV detector being used. The measurement was carried out against an external polyacrylic acid standard, which provides realistic molecular weight values due to its structural relationship with the polymers investigated. These data differ significantly from the molecular weight data, in which polystyrene sulfonic acids are used as standard. The molar masses measured against polystyrenesulfonic acids are generally significantly higher than the molecular weights specified in this document.

Suitable polymers are in particular polyacrylates, which preferably have a molecular weight of from 2,000 to 20,000 g / mol. Because of their superior solubility, the short-chain polyacrylates, which have molecular weights of from 2,000 to 10,000 g / mol, and particularly preferably from 3,000 to 5,000 g / mol, may again be preferred from this group.

Suitable polymers may also include substances consisting partly or wholly of units of vinyl alcohol or its derivatives.

Also suitable are copolymeric polycarboxylates, in particular those of acrylic acid with methacrylic acid and, acrylic acid or methacrylic acid with maleic acid. Copolymers of acrylic acid with maleic acid which contain 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid have proven to be particularly suitable. Their molecular weight relative to free acids is generally from 2,000 to 70,000 g / mol, preferably from 20,000 to 50,000 g / mol and in particular 30,000 to 40,000 g / mol. The (co) polymeric polycarboxylates can be used either as an aqueous solution or, preferably, as a powder.

To improve the water solubility, the polymers may also contain allylsulfonic acids, such as allyloxybenzenesulfonic acid and methallylsulfonic acid, as a monomer.

Also particularly preferred are biodegradable polymers of more than two different monomer units, for example those containing as monomers salts of acrylic acid and maleic acid and vinyl alcohol or vinyl alcohol derivatives or as monomers salts of acrylic acid and 2-alkylallylsulfonic acid and sugar derivatives.

Further preferred copolymers are those which preferably have as monomers acrolein and acrylic acid / acrylic acid salts or acrolein and vinyl acetate.

Also to be mentioned as further preferred builders polymeric aminodicarboxylic acids, their salts or their precursors. Particular preference is given to polyaspartic acids or their salts and derivatives which, in addition to builder properties, also have a bleach-stabilizing action.

Further suitable builders are polyacetals which can be obtained by reacting dialdehydes with polyol carboxylic acids which have 5 to 7 C atoms and at least 3 hydroxyl groups. Preferred polyacetals are obtained from dialdehydes such as glyoxal, glutaraldehyde, terephthalaldehyde and mixtures thereof and from polyol carboxylic acids such as gluconic acid and / or glucoheptonic acid.

Other suitable organic builders are dextrins, for example oligomers or polymers of carbohydrates which can be obtained by partial hydrolysis of starches. The hydrolysis can be carried out by customary, for example acid or enzyme catalyzed processes. Preferably, it is hydrolysis products having average molecular weights in the range of 400 to 500 000 g / mol. In this case, a polysaccharide with a dextrose equivalent (DE) in the range from 0.5 to 40, in particular from 2 to 30 is preferred, DE being a customary measure of the reducing action of a polysaccharide in comparison with dextrose, which has a DE of 100 , Both maltodextrins with a DE of between 3 and 20 and dry glucose syrups with a DE of between 20 and 37 and also so-called yellow dextrins and white dextrins with relatively high molecular weights in the range from 2 000 to 30 000 g / mol are useful

The oxidized derivatives of such dextrins are their reaction products with oxidizing agents which are capable of oxidizing at least one alcohol function of the saccharide ring to the carboxylic acid function. Also suitable is an oxidized oligosaccharide. A product oxidized to C _{6 of} the saccharide ring may be particularly advantageous.

Oxydisuccinates and other derivatives of disuccinates, preferably ethylenediamine disuccinate, are also other suitable builders. In this case, ethylenediamine-N, N'-disuccinate (EDDS), preferably used in the form of its sodium or magnesium salts. Also preferred in this context are glycerol disuccinates and glycerol trisuccinates.

Other useful organic builders are, for example, acetylated hydroxycarboxylic acids or their salts, which may optionally also be present in lactone form and which contain at least 4 carbon atoms and at least one hydroxyl group and a maximum of two acid groups.

However, for reasons of aesthetics, soluble, organic builders, such as citric acid, are preferably used in the thickened, liquid detergents or cleaners.

Among the compounds serving as bleaches in water H ₂ O ₂ , sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance.

Suitable derivatives include the sulfonated derivatives of the phthalic and terephthalic acid polymers.

Optical brighteners (so-called "whiteners") can be added to the detergents or cleaners to eliminate graying and yellowing of the treated textile fabrics. These fabrics impinge on the fiber and cause whitening and bleaching by transforming invisible ultraviolet radiation into visible longer wavelength light, emitting the ultraviolet light absorbed from the sunlight as faint bluish fluorescence, and pure with the yellowness of the grayed or yellowed wash White results. Suitable compounds are derived, for example, from the substance classes of 4,4'-diamino-2,2'-stilbenedisulfonic acids (flavonic acids), 4,4'-distyrylbiphenyls, methylumbelliferones, coumarins, dihydroquinolinones, 1,3-diarylpyrazolines, naphthalimides, benzoxazole , Benzisoxazole and benzimidazole systems as well as heterocyclic substituted pyrene derivatives. The optical brighteners are usually used in amounts of between 0% and 0.3% by weight, based on the finished detergent and cleaner.

Grayness inhibitors have the task of keeping the dirt detached from the fiber suspended in the liquor and thus preventing the dirt from being rebuilt. Water-soluble colloids of mostly organic nature are suitable for this purpose, for example glue, gelatine, salts of ether sulfonic acids or cellulose or salts of acidic sulfuric acid esters of cellulose or starch. Also, water-soluble polyamides containing acidic groups are suitable for this purpose.

An increased wearing comfort can result from the additional use of antistatic agents, which are additionally added to the detergents or cleaning agents. Antistatic agents increase the surface conductivity and thus allow an improved drainage of formed charges. External antistatic agents are generally substances with at least one hydrophilic molecule ligand and give a more or less hygroscopic film on the surfaces. These mostly surface-active antistatic agents can be subdivided into nitrogen-containing (amines, amides, quaternary ammonium compounds), phosphorus-containing (phosphoric acid esters) and sulfur-containing (alkyl sulfonates, alkyl sulfates) antistatic agents. Lauryl (or stearyl) dimethylbenzylammonium chlorides are suitable as antistatic agents for textile fabrics or as an additive to detergents or cleaners, wherein additionally a softening effect is achieved.

To improve the rewettability of the treated fabrics and to facilitate the ironing of the treated fabrics, for example, silicone compounds can be used in the detergent or cleaning agent.
