Abstract

The invention relates to the extensive replacement of LAS by soap or fatty acid(s) in washing or cleaning agents, without loss of cleaning power, by adding a polyester-based soil-release polymer. Perspectives are thereby disclosed regarding the replacement of surfactants based on petrochemicals, such as in particular LAS, by surfactants based on fatty chemicals, such as soap, without the consumer needing to accept loss of performance in textile washing. This allows a further step on the path of sustainable economic activity in the area of washing and cleaning agents.

Description

Detergents or cleaners containing soap and polyester-based soil release polymer

The present invention relates to a washing or cleaning agent which, in addition to customary detergent or cleaner constituents, contains> 3% by weight of fatty acid (s) and also contains a polyester-based soil-release polymer. The invention further relates to the use of a combination of polyester-based soil release polymer and> 3 wt .-% fatty acid, wt .-% based on the total agent, in a detergent or cleaning agent, to improve the cleaning performance in the textile laundry. The invention further relates to a fabric washing process using the above-mentioned laundry detergent or cleaning agent at wash temperatures <4O ⁰ C, preferably <3O ⁰ C.

Human society has in recent years developed a general need to conserve the environment in a more comprehensive manner and thus to make economic management more sustainable. In the field of detergents and cleaners, for example, it is the wish of both consumers and industry to provide just such funds that are as environmentally friendly as possible and that are in line with the principle of sustainability. For this reason, for example, the current development of universal and special detergents in Europe in accordance with legal regulations and standards, such as the EC Detergents Regulation. Accordingly, for each surfactant used today in detergents, the primary degradation must be at least 80%, the complete biodegradation (after 28 days) should be at least 60%. It is also desired not only to comply with the statutory regulations and standards, but also to make additional contributions in order to serve the preservation of the environment as much as possible. A disadvantage is considered by many consumers that the reservoir of fossil or petrochemical raw materials is finite, so conservation of these resources is strongly advocated. In addition, surfactants based on fossil fuels are very often not degradable under anaerobic conditions. A general need therefore exists to provide, in particular, those washing or cleaning agent formulations whose surfactants are prepared at least partly on the basis of renewable raw materials, for example on a oleochemical raw material basis. However, this desire remains linked to the desire to maintain the very good cleaning performance of conventional detergents and cleaners in textile laundering, which has been expected by the consumer and has now become a habit. Surfactants based on oleochemicals or based on sugars, such as, for example, fatty alcohol sulfates, alkyl polyglucosides, methyl ester sulfonates, fatty alcohol polyglycol ethers, fatty acids, are often not only effective against the currently most important surfactant group, the alkylbenzenesulfonates (LAS), which are based on petrochemical raw materials formulate worse, but they also usually offer a much lower cleaning performance at the same dosage. For the purposes of the invention, "fatty chemical base" means that the surfactant in question is essentially (ie at least partially) based on such raw materials, which result predominantly from vegetable oils, but also from animal oils and / or fats Rapeseed oil, sunflower oil, linseed oil, coconut oil, coconut oil, palm oil, palm kernel oil, soybean oil, peanut oil, castor oil etc. Important natural fats are eg beef tallow and lard.All natural fats and oils are characterized by the fact that they are predominantly to exclusively fatty acids in straight, Of these, a sharp distinction must be made between the fossil and, in particular, the petrochemical raw material base, in particular the raw materials obtainable from crude oil and natural gas. Against this general background, the concrete object of the present invention is to provide a washing or detergents which makes it possible to reduce the proportion of surfactants based on petrochemical resources (in particular LAS) while at least largely maintaining the cleaning performance to be achieved in textile washing.

This object is achieved by the subject matter of the invention, namely a washing or cleaning agent which, in addition to customary detergent or cleaner constituents, contains> 3% by weight of fatty acid (s) and also contains a polyester-based soil-release polymer,% by weight on the entire remedy. It has surprisingly been found that the composition according to the invention enables a very good cleaning performance in textile washing, even when the proportion of surfactants based on petrochemical resources, in particular alkylbenzenesulfonate, is lowered. The washing or cleaning agent according to the invention thus makes it possible to reduce the proportion of surfactants based on petrochemical resources, such as, in particular, alkylbenzenesulfonate, in detergents or cleaners and nevertheless at least maintain the desired cleaning performance as far as possible. In the context of the present invention, the anionic surfactants based on petrochemical raw materials, in particular alkanesulfonates, preferably include secondary alkanesulfonates (SAS) and alkylbenzenesulfonates, such as preferably linear alkylbenzenesulfonates, and also α-olefinsulfonates.

In a preferred embodiment of the invention, the polyester-based soil release polymer in the washing or cleaning agent according to the invention in amounts of 0.01 to 2 wt .-%, preferably 0.05 to 1, 5 wt .-%, advantageously 0, 1 to 1 wt .-%, in particular 0.15 to 0.8 wt .-%, based on the total agent included. We have found that this amount of soil release polymer helps to achieve particularly good results in terms of the cleaning effect of textile washing. However, it is also the use of> 2 wt .-% of the polyester-based soil-release polymer in the inventive washing or Cleaning agent possible. The above-mentioned very good results in the cleaning performance in textile washing are achieved especially when very special polyester-based soil release polymers are used according to the invention, as described directly below.

When the soil release polymer according to the invention comprises, in particular essentially consists of, the structural units I to III or I to IV, - [(OCHR ¹ -CHR ² ) _a -O-OC-Ph-CO-] _d ( I)

- [(OCHR ³ -CHR ⁴ ) _b -O-OC-sPh-CO-] _e (II)

- [(OCHR ⁵ -CHR ⁶ ) _c -OR ⁷ ] _f (III)

[Polyfunctional unit] _g (IV) in which a, b and c independently of one another each represent a number from 1 to 200, d, e and f independently of one another each represent a number from 1 to 50, g represents a number is from 0 to 5, Ph is a 1, 4-phenylene, sPh is a 1, 3-phenylene substituted in position 5 with a group -SO ₃ Me, Me for Li, Na, K, Mg / 2, Ca / 2, Al / 3, ammonium, mono-, di-, tri- or tetraalkylammonium, where the alkyl radicals of the ammonium ions are C ₁ -C ₂₂ -alkyl or C ₂ -C ₁₀ -hydroxyalkyl radicals or any of these R ¹ , R ² , R ³ , R ⁴ , R ⁵ and R ⁶ independently of one another are each hydrogen or a C ₁ -C ₁₈ -n- or iso-alkyl group, R ^{7 is} a linear or branched C ι-C ₃ o-alkyl group or a linear or branched C ₂ -C ₃₀ alkenyl group, a cycloalkyl group having 5 to 9 carbon atoms, a C ₆ -C ₃₀ -aryl group or a C ₆ -C ₃₀ -aryl alkygruppe stands, and

"Polyfunctional unit" stands for a unit having 3 to 6 functional groups capable of esterification reaction, so again there is a preferred embodiment of the invention.

Preference is given to polyesters in which R ¹ , R ² , R ³ , R ⁴ , R ⁵ and R ⁶ are each independently hydrogen or methyl, R ^{7 is} methyl, a, b and c are each independently a number from 1 to 200, in particular 1 to 20, particularly preferably 1 to 5, very preferably a and b = 1 and c can be a number from 2 to 10, d is a number between 1 and 25, in particular between 1 and 10, particularly preferably between 1 and 5, e is a number between 1 and 30, in particular between 2 and 15, particularly preferred between 3 and 10 and f a number between 0.05 and 15, in particular between 0.1 and 10 and particularly prefers between 0.25 and 3 means. Such polyesters can be obtained, for example, by polycondensation of dialkyl terephthalate, dialkyl 5-sulfoisophthalates, alkylene glycols, optionally polyalkylene glycols (at a, b and / or c> 1) and polyalkylene glycols end capped on one side (corresponding to unit IM). It should be noted be that for numbers a, b, c> 1 is a polymeric skeleton and thus the coefficients can take as an average of any value in the given interval. This value reflects the number average molecular weight. As the unit (I) is an ester of terephthalic acid with one or more difunctional, aliphatic alcohols in question, preferably used here are ethylene glycol (R ¹ and R ^{2 are} each H) and / or 1,2-propylene glycol (R ¹ = H and R ² = - CH ₃ or vice versa) and / or shorter-chain polyethylene glycols and / or poly [ethylene glycol-co-propylene glycol] with number-average molecular weights of 100 to 2000 g / mol. In the structures, for example, from 1 to 50 units (I) can be contained per polymer chain. As the unit (II) is an ester of 5-sulfoisophthalic acid with one or more difunctional, aliphatic alcohols in question, preferably used are the aforementioned. In the structures, for example, 1 to 50 units (II) may be present. Poly (ethylene glycol-co-propylene glycol) monomethyl ethers having average molecular weights of 100 to 2000 g / mol and polyethylene glycol monomethyl ethers of the general formula CH ₃ -O- (C ₂ H ₄ O) are preferably used as nonionically unilaterally sealed polyalkylene glycol monoalkyl ethers according to unit (III) _n -H with n = 1 to 99, in particular 1 to 20 and more preferably 2 to 10. Since the theoretical quantitative conversion of the maximum molecular weight of a polyester structure to be achieved by using such unilaterally closed ethers, the preferred use amount of the structural unit ( IM) the one necessary to achieve the mean molecular weights described below. Apart from linear polyesters which result from the structural units (I), (II) and (III), the use of crosslinked or branched polyester structures is also possible according to the invention. This is expressed by the presence of a crosslinking polyfunctional structural unit (IV) having at least three to a maximum of 6 functional groups capable of esterification reaction. For example, acid, alcohol, ester, anhydride or epoxy groups can be named as functional groups. Different functionalities in one molecule are also possible. Citric acid, malic acid, tartaric acid and gallic acid, particularly preferably 2,2-dihydroxymethylpropionic acid, may be used as examples for this purpose. Furthermore, polyhydric alcohols such as pentaerythrol, glycerol, sorbitol and / or trimethylolpropane can be used. These may also be polybasic aliphatic or aromatic carboxylic acids, such as benzene-1,2,3-tricarboxylic acid (hemimellitic acid), benzene-1,2,4-tricarboxylic acid (trimellitic acid), or benzene-1,3,5-tricarboxylic acid ( Trimesithsäure) act. The proportion by weight of crosslinking monomers, based on the total weight of the polyester, can be, for example, up to 10% by weight, in particular up to 5% by weight and particularly preferably up to 3% by weight. The polyesters containing the structural units (I), (II) and (III) and optionally (IV) generally have number average molecular weights in the range from 700 to 50,000 g / mol, the number average molecular weight can be determined by size exclusion chromatography in aqueous solution using a calibration using narrowly distributed polyacrylic acid Na salt - Standards. The number-average molecular weights are preferably in the range from 800 to 25,000 g / mol, in particular from 1,000 to 15,000 g / mol, particularly preferably from 1,200 to 12,000 g / mol. According to the invention, solid polyesters which have softening points above 40 ^° C. are preferably used as part of the particle of the second type; they preferably have a softening point between 50 and 200 ⁰ C, particularly preferably between 8O ⁰ C and 15O ⁰ C and extremely preferably between 100 ⁰ C and 12O ⁰ C. The synthesis of the polyesters may be prepared by known methods, for example by the above-mentioned Components are first heated under normal pressure with addition of a catalyst and then builds up the necessary molecular weights in vacuo by distilling off superstoichiometric amounts of the glycols used. Suitable for the reaction are the known transesterification and condensation catalysts, such as, for example, titanium tetraisopropylate, dibutyltin oxide, alkali metal or alkaline earth metal alkoxides or antimony trioxide / calcium acetate. For further details, see EP 442 101. Preferably used polyesters are of solid consistency and can easily be ground into powder or be compacted or agglomerated into granules of defined particle sizes. The granulation can be carried out by solidifying the copolymers obtained as melt in the synthesis by cooling in a cool gas stream, for example air or nitrogen, or by application to a flaking roll or to a treadmill to form flakes or flakes. This coarse material can optionally be further ground, for example, in the roll mill or in the screen mill, which can be followed by a sieving and a rounding as described above. The granulation can also be carried out in such a way that the polyesters are ground to powder after solidification and then reacted by compaction or agglomeration and the above-described rounding into granules with defined particle sizes. It is precisely the preferred soil release polymers described above that, with a partial and even very extensive substitution of LAS by soap or fatty acid (s), the cleaning performance in textile washing at least largely remains preserved. Preferred soil release polymers are also described in WO 2007/079850 A1, to which reference is hereby fully made.

It is particularly advantageous to use the soil-release polymer in granular form, in particular with a particle size distribution as follows:

> 1.6 mm <1%

0.8 mm -1, 6 mm <20%

0.4 mm - 0.8 mm 50 - 80%

0.1 mm-0.4 mm 15 - 45%

<0.1mm <5%. The washing or cleaning agent according to the invention necessarily contains> 3% by weight of fatty acid (s). The term fatty acid according to the invention also includes its salts, in particular its sodium, potassium or ammonium salts, ie the so-called soaps. Particularly suitable fatty acids are, for example, capric acid, undecanoic acid, dodecanoic acid, tridecanoic acid, tetradecanoic acid, palmitic acid, stearic acid, arachic acid, behenic acid, oleic acid and / or linoleic acid, ie fatty acids which are obtainable from natural fats and oils, such as coconut oil, palm oil or rapeseed oil. In particular, mixtures derived from natural fatty acids, eg coconut, palm kernel or tallow fatty acids, are preferred. Very particularly preferred is, for example, a Ci ₂ - Cis fatty acid mixture containing in particular Ci ₂ -, Ci ₄ -, Ci ₆ - and Ci ₈ fatty acids. A commercially available example of such a mixture is, for example, Edenor® K 12-18, available from Cognis Deutschland GmbH.

The fatty acids may advantageously be present in quantities of up to 25% by weight, more advantageously up to 20% by weight, preferably 3-15% by weight, in particular 5-10% by weight, in the washing or cleaning agent according to the invention. This corresponds to a preferred embodiment of the invention. The lower limit may also be 6 or 7 wt .-%. The upper limit may also be 12% by weight.

The washing or cleaning agent according to the invention preferably also contains anionic surfactant, e.g. linear alkyl benzene sulfonate, e.g. Fatty alcohol sulfate. The linear alkylbenzenesulfonate is preferably in amounts of 0.01-20% by weight, more preferably 3-15% by weight, more preferably 4-12% by weight, in particular in amounts of 5-10% by weight, based on the total mean, included. A suitable upper limit may e.g. also at 8 wt .-% or 6 wt .-% are. A particular advantage of the present invention is that even at reduced levels of linear alkyl benzene sulfonate, i. e.g. <15% by weight or e.g. <10% by weight or e.g. <8% by weight or e.g. even <6% by weight, yet a very good cleaning performance according to the invention in the textile washing is achieved.

If the washing or cleaning agent according to the invention should contain alkanesulfonates, which is possible, but is less preferred according to the invention, then at most in amounts of <15% by weight, for example 0.01% by weight to <10% by weight, but preferably in Amounts <5 wt .-% or <1 wt .-% or <0.5 wt .-%, based on the total detergent or cleaning agent. In particular, however, according to a preferred embodiment of the invention, no alkanesulfonate is contained in the composition according to the invention. Alkanesulfonate is the collective name for compounds of the general formula R-SO ₂ -OM, where R is a - usually secondary - alkyl radical and M is a monovalent cation, preferably sodium. If the washing or cleaning agent according to the invention should contain α-olefinsulfonates, which is possible, but less preferred according to the invention, then at most <15 wt .-%, for example 0.01 wt .-% to <10 wt .-%, preferably but in amounts <5% by weight or <1% by weight or <0.5% by weight, based on the total washing or cleaning agent. In particular, however, according to a preferred embodiment of the invention, no α-olefinsulfonate is present in the composition according to the invention.

α-Olefinsulfonat is the collective name for compounds of the general formula R-CH = CH- (CH 2) n -SO 2 -OM, wherein R is a - usually linear, primary - alkyl radical and M is a monovalent cation, preferably sodium , stands (n = 1 or 2). As a rule, technical α-olefin sulfonates consist of hydroxyalkanesulfonates and alkene sulfonates in a ratio of 2: 1.

The total quantity of petrochemical raw material anionic surfactants may advantageously be <20% by weight, preferably ≦ 15% by weight, more preferably ≦ 10% by weight, more preferably <8% by weight and in particular <6% by weight, relative to the total mean.

Preferably, fatty alcohol sulfates (based on a substantially oleochemical base) may be present in the washing or cleaning agent according to the invention. Fatty alcohol sulfates are well known to those skilled in the washing or cleaning detergents as such. Preferred fatty alcohol sulfates can be described by the formula, R ² O-SO ₃ X. They are available, for example, by reaction of preferably saturated fatty alcohols with concentrated sulfuric acid, gaseous sulfur trioxide, chlorosulfonic acid or sulfamic acid.

In the formula, R ² O-SO ₃ X, R ^{2 is} a particularly linear (or branched) aliphatic alkyl and / or alkenyl radical having 6 to 22, preferably 12 to 18 carbon atoms and X is an alkali and / or alkaline earth metal , Ammonium, alkylammonium, alkanolammonium or glucammonium. Particular preference is given to fatty alcohol sulfates based on C _12/14 , C _12/18 and C _16/18 fatty alcohols, preferably in the form of their sodium salts.

The washing or cleaning agent according to the invention may comprise fatty alcohol sulphate, e.g. in amounts of from 0% to <15% by weight, e.g. 0.01 wt .-% to <10 wt .-%, but preferably in amounts <8 wt .-% or <6 wt .-% or <5 wt .-%, based on the total detergent or cleaning agent. According to another embodiment of the invention, it is also possible that no fatty alcohol sulfate is contained in the agent according to the invention.

In a further preferred embodiment of the invention, the washing or cleaning agent according to the invention additionally contains nonionic surfactant, wherein for the purposes of the invention 8th

Unless otherwise stated below, the alkyl radicals R ^{1 of} the APG are linear unsaturated radicals having the stated number of carbon atoms.

APG are nonionic surfactants and are known substances that can be obtained by the relevant methods of preparative organic chemistry. The index number x indicates the degree of oligomerization (DP degree), i. the distribution of mono- and oligoglycosides, and stands, as just described, for a number between 1 and 10. While x must always be integer in a given compound and can take here especially the values x = 1 to 6, the value x is an analytically determined arithmetic variable for a given alkyl glycoside, which usually represents a fractional number. Preferably, alkyl glycosides having a mean degree of oligomerization x of 1.1 to 3.0 are used. From an application point of view, those alkyl glycosides whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.6 are preferred.

Typical examples are caproic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol, and technical mixtures thereof, such as those obtained in the course of the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelene's oxosynthesis. Preferably, however, the alkyl or alkenyl radical R is derived from lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol or oleyl alcohol.

Sugar esters are also preferred nonionic surfactants. Sugar esters are esters of sugar alcohols, in particular sucrose (ie sucrose esters) with organic or inorganic acids, in particular with fatty acids (derivatives), for example obtainable by reactions of sucrose with fatty acid esters in solution or melt or from alkali-catalyzed transesterifications with triglycerides. Monoesters of short-chain fatty acids may be preferred, e.g. Monoester of lauric acid.

Also Fettsäuresarcosinate are preferably usable nonionic surfactants. The fatty acid sarcosinates are the condensation products of fatty acids with N-methylglycine. Fatty acid sarcosinates can be prepared by reacting N-methylglycine with fatty acid chloride. For example, fatty acid sarcosinates based on C 12 to C 18 fatty acids are particularly preferred. Fatty acid sarcosinates are characterized by a pronounced foaming power, while they also show a low sensitivity to water hardness and high skin tolerance. Preferred fatty acid sarcosinates can be described by the following general formula (XI): 1 1

R ¹ -CO is generally a fatty acid radical, in particular a stearic, coconut oil or olein radical. As the alkanolamine, di-, monoethanolamine or aminopropanols can be used, whereby the meaning of R ² and n are defined in just mentioned formula.

Likewise, fatty amines can be used in the invention. Fatty amines are for example obtainable by a process starting from fatty alcohols, which are reacted at 210-260 ⁰ C in the presence of dehydrogenation catalysts with ammonia or short chain alkyl or dialkylamines. The salts of fatty amines are cationic emulsifiers. These are included in the term fatty amine. By alkylation, quaternary ammonium compounds can be obtained.

A preferred amine oxide is, for example, cocoamidopropylamine oxide. 12

Likewise, protein-fatty acid condensates can be used in the invention. Protein-fatty acid condensates can be prepared, for example, by acylating protein hydrolysates, e.g. with fatty acids, fatty acid methyl esters, but preferably fatty acid chlorides or substituted maleic anhydrides. Particularly preferred protein-fatty acid condensates can be described by the following formula:

N is preferably 1-13. Very well known are, for example, the Lamepon® types, Gluadin® types, Hostapon® KCG or the Amisoft® types.

Alkoxylated fatty alcohols can also be used. Alkoxylated fatty alcohols can be obtained essentially on a oleochemical basis, namely by reacting corresponding fatty alcohols with alkylene oxide, preferably ethylene oxide. The necessary alkylene oxide can also be obtained via biomass, but usually comes from petrochemical sources. For the purposes of the present invention, the alkoxylated fatty alcohols are added to the surfactants on (essentially) oleochemical raw material basis, regardless of the origin of the alkylene oxide, since in any case the fatty alcohol is accessible from the oleochemical source. In particular, alcohol ethoxylates with linear radicals of alcohols of native origin having 12 to 18 carbon atoms, for example of coconut, palm, palm kernel, tallow or oleyl alcohol, and on average 2 to 8 EO per mole of alcohol are preferred. The preferred ethoxylated alcohols include, for example, Ci ₂ -Ci ₄ -AIkOhOIe with 3 EO to 6 EO, C ₉ -Ci i alcohols with 7 EO, Ci ₃ -Ci ₅ -alcohols with 3 EO, 5 EO, 7 EO or 8 EO, Ci ₄ -Ci ₅ -Alkohole with 4 EO, 5 EO, 7 EO or 9 EO, Ci ₂ -Ci ₈ alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of C ₁₂ -C ₁₄ -AlkOhOl with 3 EO and C ₁₂ - C 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. Also biosurfactants, ie surfactants that are formed by microorganisms can be used. The biosurfactants are usually simple or complex lipids or lipid derivatives having a hydrophilic and a hydrophobic (lipophilic) end such as mono- and diglycerides, sophorolipids, rhamnolipids.

It may also be advantageous to use only small amounts of alkoxylated fatty alcohol, for example <5 wt .-%, preferably <3 wt .-%, in particular <2 wt .-% or even <1 wt .-%, based on the total agent , It is even possible that no alkoxylated fatty alcohol is contained at all.

The total amount of surfactants present in the washing or cleaning agent according to the invention is in principle variable. A total amount of e.g. However, 5-50% by weight, preferably 10 -35% by weight, in particular 15-30% by weight, of surfactants in the washing or cleaning agent according to the invention has proven to be very advantageous as far as the detergency in textile washing is concerned and therefore corresponds to a preferred embodiment of the invention. A reasonable upper limit may e.g. even at 20 wt .-% are.

According to a further preferred embodiment of the invention, it is preferred that the washing or cleaning agent according to the invention comprises enzymes, preferably amylase, protease, mannanase, tannase, carbonic anhydrase, pectinase, lipase and / or cellulase, advantageously in amounts of 0.01-5%. Wt .-%, based on the total agent. Below, enzymes are picked up again.

According to another preferred embodiment of the invention, the washing or cleaning agent according to the invention contains a phosphate-containing builder system, wherein phosphate is preferably present in amounts of 1-40 wt .-%, in particular 5-30 wt .-%, based on the total agent.

According to a further preferred embodiment of the invention, the inventive washing or cleaning agent has a pH> 7.5, as measured in a 5% solution of the composition in water at 2O ⁰ C.

The washing or cleaning agent according to the invention can be present in any form, ie be solid, liquid, pasty or semi-solid form. However, it is preferred if the washing or cleaning agent according to the invention is in solid form. According to a preferred embodiment of the invention, the washing or cleaning agent according to the invention is therefore in solid form, is in particular powdery or granular, advantageously it is in the form of a shaped body, in particular in tablet form.

If the bulk density of the washing or cleaning agent according to the invention is 350-750 g / L, preferably 450-650 g / L, then a preferred embodiment of the invention is likewise present.

A further preferred embodiment of the invention is when the fatty acid (s) is at least partially, in particular completely contained in the form of spray-drying products in the washing or cleaning agent according to the invention. The spray-drying for the preparation of suitable fatty acid-containing spray-drying products can be carried out by the customary processes for the preparation of pulverulent detergents or cleaners. The first step of a conventional spray-drying process is generally to prepare an aqueous slurry of the detergent ingredients to be spray-dried, which advantageously neither volatilizes nor decomposes under spray-drying conditions. This 15

Slurry usually comprises surfactants, builders and adjusters. In the present case, it would thus also include fatty acid (s). A possible slurry may comprise, for example, fatty acid (s)> 6% by weight and water <60% by weight,% by weight, based on the total slurry. The slurry is then pumped into the spray tower and sprayed through nozzles located in the top of the tower. In this case, rising, hot air at a temperature of preferably 200 to 35O ⁰ C dries the slurry and evaporates the adhering water. At the outlet of the tower (temperature preferably 80-120 ⁰ C) then fall dried, fine powder. It is preferred to use such fatty acid-containing spray-drying products within the scope of the invention.

Another object of the invention is the use of a combination of polyester-based soil release polymer and> 3 wt .-% fatty acid, wt .-% based on the total agent, in a detergent or cleaning agent, to improve the cleaning performance in the Textile laundry, in particular polyester and polyester blends, at a washing temperature

<4O ⁰ C, preferably <3O ⁰ C. This use is characterized in that it allows a substantial substitution of LAS by soap or fatty acids in detergents or cleaners. Another object of the invention is a textile washing process using a washing or cleaning agent according to the invention at washing temperatures <40 ⁰ C, preferably

<3O ⁰ C.

In the following, some possible ingredients of the washing or cleaning agents according to the invention are described in detail without claiming to be complete. As anionic surfactants, for example, those of the sulfonate type and sulfates can be used. In general, in the context of the invention, anionic surfactants based on oleochemicals can preferably be used. Anionic surfactants on substantially (ie at least proportionately) oleochemical base, ie essentially based on renewable raw materials in the form of natural fats and oils, are in particular the ester sulfonates, preferably the methyl ester sulfonates (MES), and the fatty alcohol sulfates (FAS). Thus, ester sulfonates (on a substantially oleochemical basis) can be used. Preferably usable ester sulfonates contain in the molecule a terminal ester and a sulfonate function, usually adjacent in the α-position. This example α-ester can be obtained by reacting alkyl esters with usual sulfating agents, preferably luftverdünntem, dry sulfur trioxide (SO3) at 8O ⁰ C and subsequent neutralization. Preference is given in particular to methyl esters based on coconut oil (C12 / 14 chain), palm kernel oil (palm kernel sulfo fatty acid ester) or else of taigmethyl ester (C16 / 18 chain). Particularly preferred ester sulfonates can be described by the formula: 16

^" R" CH - COOR ^Γ

M ^{n +} so / n

(I)

In this formula (I), R is, on average, a C ₆ -C ₂₂ alkyl radical. It may preferably be a C ₁₀ -C ₁₈ -alkyl radical, C ₁₂ -C ₁₄ -alkyl radical, C ₁₄ -C ₁₆ -alkyl radical, C ₁₂ -C ₁₅ -alkyl radical, C ₈ -C ₁₀ -alkyl radical, C ₁₆ -C ₁₈ - alkyl, C ₁₆ alkyl, C ₁₂ --i ₆ alkyl or C ₁₂ -C ₁₈ alkyl. However, most preferred are C ₁₆ -C ₁₈ -alkyl radicals, C ₁₂ . ₁₆ -alkyl radicals, C ₁₆ -alkyl radicals or C ₁₂ -C ₁₈ -alkyl radicals. In this formula (I), R1 is, on average, a C ₁ -C ₆ -alkyl radical, particularly preferably a methyl radical. In this formula (I), n is the number 1 or 2, preferably 1. In this formula (I) M ^{n + is} the counterion, where M is preferably Na, K, Ca, Mg, H, monoethanolammonium, diethanolammonium, triethanolammonium or a mixture of it. In this case, n + is either 1 + or 2+, depending on the type of M. As counterion Na ⁺ , K ⁺ or Mg ^{+ is} preferred.

Likewise, fatty alcohol sulfates (on a substantially oleochemical basis) can be used. Particular preference is given to fatty alcohol sulfates based on C _12/14 , C _12/18 and C _16/18 fatty alcohols, preferably in the form of their sodium salts. In the case of branched primary alcohols are oxo alcohols, as they are accessible, for example, by reacting carbon monoxide and hydrogen to alpha-olefins by the shop process. Alkyl sulfates based on oxo alcohols are therefore not anionic surfactants based on oleochemicals.

Also fatty alcohol ether sulfates (FAES) can be used. FAES can be obtained substantially on a oleochemical basis, namely by reacting fatty alcohols on (essentially) oleochemical raw material base with alkylene oxide (preferably ethylene oxide) to give fatty alcohol alkoxylates and subsequent reaction with eg sulfur trioxide and neutralization to fatty alcohol ether sulfates. Although the necessary alkylene oxide, preferably ethylene oxide, is generally produced from petrochemical sources. However, it can also be obtained from the biomass, for example by reacting bioethanol (eg from sugar beet) to ethylene and subsequent oxidation to ethylene oxide. This is especially economically viable with a correspondingly low-cost biomass supply, eg in countries such as Brazil or India. For the purposes of the present invention, the group of fatty alcohol ether sulfates is added to the anionic surfactants on (substantially) oleochemical raw material base, regardless of the origin of the alkylene oxide, since in any case the fatty alcohol component is accessible from a oleochemical source. Fatty alcohol ether sulfates, fatty alcohol sulfates and / or ester sulfonates can according to a preferred embodiment in the inventive agent in amounts of eg 0-20 wt .-%, advantageously in amounts of 0.01 wt .-% to 15 wt .-%, for example in amounts of 1 wt .-% to 10 wt .-%, based on the total washing or cleaning agent, be included. 17

According to a further preferred embodiment of the invention, however, only little, for example <5% by weight, <2% by weight or <1% by weight, based on the total agent, or even no fatty alcohol ether sulfate, fatty alcohol sulfate and / or Ester sulfonate contained in the agent according to the invention.

The total content of the washing or cleaning agent according to the invention of anionic surfactants can vary within wide ranges. Thus, an agent according to the invention can contain very large amounts of anionic surfactant, preferably up to an order of magnitude of up to 40, 50 or 60% by weight or more. Likewise, an agent according to the invention may contain only very small amounts of anionic surfactant, for example less than 15 or 10% by weight or less than 5% by weight or even less. However, anionic surfactants are advantageously present in the compositions according to the invention in amounts of 1 to 40% by weight and in particular 5 to 30% by weight, with concentrations above 10% by weight and even above 15% by weight finding particular preference can. According to a preferred embodiment, the washing or cleaning agent according to the invention contains anionic surfactants, preferably in amounts of at least 0.1% by weight, based on the total washing or cleaning agent. The anionic surfactants and soaps 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. Preferably, they are in the form of their sodium or potassium salts, especially in the form of the sodium salts. Advantageously, nonionic surfactants may also be included in the detergents or cleaners according to the invention. For example, their content may be up to 2 or 3 or 5 wt .-%. It may also contain greater amounts of nonionic surfactant, for example up to 10 wt .-% or 15 wt .-% or 20 wt .-%, 30 wt .-%, 40 wt .-%, 50 wt .-% or even beyond, if appropriate. Useful lower limits may be values of 0.01, 0.1, 1, 2, 3 or 4 wt .-%, wt .-% in each case based on the total mean. According to a preferred embodiment, the washing or cleaning agent according to the invention contains nonionic surfactants, preferably in amounts of at least 0.1% by weight, based on the total washing or cleaning agent. According to another preferred embodiment, the agent according to the invention is free of nonionic surfactant. All nonionic surfactants known from the prior art may be present in the compositions according to the invention, although those based on oleochemicals are preferred. The detergents or cleaners according to the invention may preferably also contain cationic surfactants. The detergents or cleaners according to the invention may contain one or more cationic surfactants, advantageously in amounts, based on the total composition, of from 0 to 30% by weight, more preferably greater than 0 to 20% by weight, preferably from 0.01 to 10 Wt .-%, in particular 0.1 to 5 wt .-%.

Cleaning results:

The washing results were evaluated in each case after 5 washing cycles (the mean values from 5 experiments in each case). 21

With detergent 1, the following results were obtained: a) cotton 2O ⁰ C; Stain removal, remission value Y / IEC standard (average of 15 stains according to AFISE standard): 66.8 b) cotton 4O ⁰ C; Stain removal, remission value Y / IEC standard (average of 15 stains according to AFISE standard): 72.3 c) polyester 2O ⁰ C; Stain removal, remission value Y / IEC standard (average of 6 stains according to AFISE standard): 54.9 d) polyester 4O ⁰ C; Stain removal, remission value Y / IEC standard (average of 6 stains according to AFISE standard): 55.2

Evaluation of cleaning results:

The comparison of the cleaning performance of the detergents 1 and 2 showed that a substitution of 50% by weight of the LAS used by fatty acid in the textile washing of both cotton 22 results in significant decreases in cleaning performance from polyester fabrics. These losses are dramatic and intolerable, particularly with respect to the polyester fabric.

The comparison of the cleaning performance of the detergents 1 and 3 showed that a substitution of 50% by weight of the LAS used by fatty acid with simultaneous use of soil-release polymer according to the invention is readily possible, i. without having to accept significant losses in cleaning performance.

In the textile washing of cotton at 4O ⁰ C, the cleaning performance is even slightly improved despite 50% reduction in LAS content.

The examples make it clear how the substitution of large quantities of LAS by fatty acid in detergents can be overcome without reducing the usual cleaning performance.
