Description

technical item

This application relates to agents comprising at least one alkoxylated fatty acid alkyl ester and at least one other surfactant class which is based on fatty acids from C-18 vegetable oils and has a high proportion of long-chain and mostly unsaturated hydrocarbon chains. Another subject is its use as a washing and cleaning product, preferably as a concentrate, the use of the agent for washing and cleaning textiles and fibers and the use of the agent for color or material protection, and a washing or cleaning process. The agents have a lower toxicological and ecotoxicological risk potential, increased sustainability and less impact on the environment.

State of the art

Detergents with alkoxylated fatty acid alkyl esters are known and are used as alternatives to alkoxylated fatty alcohols because of their better environmental properties. With this exchange, the cleaning performance is essentially retained, as shown in earlier publications on grease, the solubility in water is good (e.g. EP 0997521). Alkoxylated fatty acid alkyl esters are combined with other surfactants that have a less advantageous environmental behavior and/or a potential health hazard. This is accepted in order to obtain inexpensive, widely applicable and flexible surfactant systems for use in detergents and cleaning agents. In particular, surfactants made from fatty acids from tropical oils or petroleum are used to a large extent. According to the prior art, surfactants based on fatty acids which are predominantly saturated and carry hydrocarbon radicals with 8-18 carbon atoms, such as those obtained from coconut oil or palm kernel oil, are used in combination with alkoxylated fatty acid alkyl esters. Examples of surfactants that are usually combined with alkoxylated fatty acid esters are C12-C18 alkyl ether sulfates, C12-C18 alkyl sulfates, C12-C18 alkyl benzene sulfonates, olefin sulfonates, C8-C18 alkoxylated fatty alcohols (e.g. EP 3144 373) or alkyl polyglycosides (e.g. US 5,753,606 ). These surfactants have proven to be robust over a high pH range, compatible with almost all common ingredients and can therefore be used flexibly with good cleaning performance on all common types of dirt. However, due to the finite nature of petroleum and the destruction of tropical rainforest for the cultivation of tropical oil plants and the associated climate problems, it is desirable to use surfactants based on more sustainable fatty acid sources to an increasing extent. In addition, colored textiles or surfaces are affected by high washing and cleaning performance. An undesirable graying effect due to color transfer to light-colored textiles often has to be accepted. The problem of color leaching and transfer is solved by additives such as PVP or color transfer inhibitors. Disadvantages are undesirable side effects of these components, such as fixation of stains on the fabric, as well as disadvantages in terms of costs and the environment. Many common surfactants are also declared as hazardous to health, skin or eye irritants. For example, the most frequently used surfactants such as sodium lauryl sulfate, sodium laureth sulfate, alkylbenzenesulfonate, cocoamidopropylamide or alkylpolyglycoside or -glucoside cause serious eye damage. Accident reports of swallowing and eye burns are increasing, especially with the colorful detergent pods. It is therefore desirable to produce an agent with a lower risk potential. The problem of environmentally and climate-friendly agents for washing and cleaning products, in particular with a low CO2 footprint while at the same time protecting material and people, has not been solved. In recent years, biosurfactants have been offered as alternative surfactants, which are characterized by low toxicity and good environmental behavior, as well as good cleaning performance. However, the commercial use of biosurfactants is limited due to the high cost of these specific surfactants. In addition, many consumers reject the use of genetically modified organisms, which are used to a large extent for the production of biosurfactants. The complex technical task of this invention was therefore to produce alternative agents as and for washing and cleaning products which are characterized by good, comprehensive environmental behavior, a reduced CO2 footprint and a low toxicological hazard potential. For reasons of sustainability, the proportion of surfactants whose hydrophobic (lipophilic) part is derived from petroleum or tropical oils such as coconut, palm or palm kernel vegetable oils should be reduced or not used at all. The oils should preferably be of vegetable origin, i.e. not of animal origin. This is technically demanding insofar as the lauric acid (C12) otherwise desired cannot be obtained in sufficient quantities from most vegetable oils, such as those from European cultivation. Instead, European vegetable oils have a high proportion of unsaturated, long fatty acid residues ≥ C18, which bring completely new properties to the agents such as solubility, foam, stability, cleaning performance, wetting ability, compatibility, etc. Furthermore, it was a preferred goal to use one and the same surfactant mixture over a wide pH range and to combine it with different ingredients in order to have a basis for different uses in favor of good economy and cost efficiency. The agents according to the invention should preferably be based on natural raw materials to the greatest possible extent and should preferably be readily biodegradable.

Surprisingly, it has been found that means as defined in the claims and described below solve one or more of the stated objects. Surprisingly, it was found that the washing and cleaning agents according to the invention, in addition to good cleaning performance, are able to wash and clean in a material- and color-friendly manner. Colors are better preserved during the cleaning process, bleeding is reduced and materials are protected. In addition, the color transfer of the colors dissolved in the washing liquor to light-colored materials during the washing and cleaning process is unexpectedly reduced. Additives for color fixation and color transfer inhibitors can be dispensed with. Due to the good and yet material-friendly cleaning performance, the agents are suitable for a wide range of applications, such as cleaning surfaces and textiles, especially colored textiles or surfaces, e.g. for color detergents. The inventive agents are also characterized by good environmental behavior and sustainability, in particular by improved degradability, lower aquatic toxicity and a smaller CO2 footprint compared to conventional agents according to the prior art. The inventive compositions also have a favorable toxicological profile, particularly in relation to oral toxicity, dermal toxicity, skin irritation, eye irritation and allergenic potential. Surprisingly, it was possible in this way to obtain agents which can also be used as concentrates and which, despite the high surfactant concentrations, pose a low risk potential for humans and the environment. From a technical point of view, low-foam applications are often desirable. Surprisingly, the agents according to the invention develop little foam, such as is preferred for machine use from a technical point of view. Expensive and environmentally harmful defoamers can be dispensed with. Furthermore, the agents can be rinsed off well. As a result, the products based on the agents according to the invention can be easily rinsed off, especially with cold water applications. The agents can preferably be removed by a single rinsing process (“one-rinse detergents”). This enables an ecological and water-saving process for using the inventive agents, in particular for mechanical cleaning of surfaces and textiles. The alkoxylated fatty acid alkyl esters can be used as primary surfactants in the agents according to the invention and as such, in combination with co-surfactants, as described in the application, develop their advantageous properties. The agent according to the invention is also disclosed in a preferred preservative-free embodiment.

The agents have such a good cleaning effect that, in preferred embodiments, enzymes and/or bleaching agents can be dispensed with. Surprisingly, the inventive agents can also be used as high concentrates. Technically, they are therefore also preferred for high concentrates, ultra concentrates, sachet and pod applications. The inventive agents are stable as high concentrates; if necessary, other more sensitive ingredients can be spatially separated (compartments) for storage and sale in these applications. This is particularly the case in embodiments using bleach. In particular, it is advantageous that the agents according to the invention can be used over a wide pH range, thus allowing a wide range of products and applications. Another advantage of the invention is that, unlike the anionic surfactant systems commonly used, such as sodium lauryl sulfate, sodium laureth sulfate or sodium alkylbenzene sulfonate, the agents according to the invention are less sensitive to hard water and therefore do not reduce dirt-carrying capacity in the presence of calcium or Magnesium ions takes place. Sulfur surfactants can irritate the skin and mucous membranes. In a preferred embodiment, the agents are produced without medium-chain sulfuric surfactants, in particular completely without sulfuric surfactants, and thus take care of the "sulfate-free" trend. Nonionic surfactants such as decyl glucoside or biosurfactants, which are usually used for hard water, can be minimized or even eliminated in this way. Due to the high efficiency, even in hard water, this allows a lower dosage of the agent, which means that the use as a concentrate is particularly preferred. The amount of builder substances can also be reduced. The agents are suitable for the production of washing and cleaning products by metering in the agent as a whole, also from dosing systems, or from separate compartments (e.g. in the case of pods) with in-situ production of the agent at the point of use. In a further subject matter of the invention, the invention relates to the use of the agents for the production of or as washing and cleaning agents. In a further subject matter of the invention, the invention relates to methods comprising a) the provision of a washing and cleaning solution comprising an agent according to the first subject matter of the invention. b) bringing a biological or natural surface, a hard or flexible surface, as well as textiles, carpets or natural fibers into contact with the washing and cleaning solution according to (a). The agents according to the invention can be in liquid, jelly-like, paste-like, foam-like or solid form. The preferred embodiment is liquid, jelly, paste or foam. A particularly preferred use of the agents is the product form of the portioned washing and cleaning products, in particular in the form of the abovementioned concentrates. This can be in the form of solid products (e.g. tabs, tablets, lozenges, extrudate, etc.), in the form of cloths made of woven, knitted or warp-knitted textiles, of paper, wadding, felt or fleece (e.g. of polypropylene, polyester or viscose ) and their composites, which is impregnated with the agent for washing and cleaning purposes, or in the form of the liquid products preferred here. These are offered wrapped. The coating can be water-soluble, e.g. water-soluble polymers, and can consist of spatially separate compartments for individual ingredients (e.g. bleaching agents, enzymes, etc.). The casing can also be in the form of a primary packaging, e.g. made of plastic or glass, or a manual or mechanical dosing device or a cartridge. Another subject of the invention is the use of the agent as a washing or cleaning product for biological or natural surfaces, hard or flexible surfaces, and for textiles, carpets or natural fibers. Another preferred use, independent of the previous one, is the cleaning and washing of textiles, carpets or natural fibers.

Surfactant B based on fatty acids from C-18 vegetable oils

The agents according to the invention additionally contain at least one further surfactant B as defined in the claims based on C-18 vegetable oils, as defined above. Essential to the invention is the hydrophobic portion of the surfactant derived from C-18 vegetable oils. The agent contains at least one further surfactant B selected from the group comprising anionic surfactants according to claims, nonionic, cationic and amphoteric surfactants, the hydrophobic part of the surfactant(s) being derived from an aliphatic, saturated, mono- or polyunsaturated hydrocarbon radical having 6-24 carbon atoms of a C-18 vegetable oil, where the hydrocarbon residue of the surfactant(s) B or preferably the hydrocarbon residues of a mixture of surfactants of a surfactant type B is predominantly long-chain and unsaturated, the proportion of linear, even-numbered hydrocarbon residues having 18 and more carbon atoms being more than 60 wt %, preferably above 72% by weight and most preferably above 77% by weight; and wherein the proportion of linear, even-numbered, unsaturated hydrocarbon radicals, i.e. having one or more internal double bonds, is more than 55% by weight, preferably more than 65% by weight and particularly preferably more than 72% by weight, based in each case on the total weight on hydrocarbon residues of the hydrophobic part in the surfactant(s) B.

There is preferably a mixture of surfactants with at least two different hydrocarbon radicals according to the above-defined proportions relating to chain length and degree of saturation, the hydrophobic part of at least one of these surfactants being derived from C-18 vegetable oils; Hydrocarbon residues, such as are obtained in the conversion of natural vegetable oil without fractional distillation to separate the individual fatty acid derivatives, and very particularly preferably, there is a mixture of surfactants with hydrocarbon residues corresponding to the distribution of fatty acids in the natural oil. All of the surfactants B are very particularly preferably present as a surfactant mixture with different hydrocarbon radicals. Such preferred mixtures of one or more of the surfactants B have technical advantages in the compositions, in addition to better economics and a better ecological balance (no or few complicated cleaning steps).

In the case of C-18 vegetable oils, the origin or the fatty acid composition is often included in the INCI name of the surfactant.

In a preferred embodiment, R 3 can also be substituted with sulfonate or sulfonates. This is the case when sulfonated fatty acid esters or fatty acids are present as surfactant(s) B.

Very particular preference is given to representatives of the anionic surfactants according to claims, the nonionic, cationic or amphoteric surfactants B, independently of one another and freely combinable, selected from the group of surfactant structures comprising: salts of fatty acids of the general formula R 3 COOM, fatty acid esters with the general formula R<3>COOR', fatty acid amides with the general formula R<3>CONR'R'' or R<3>CONHR', fatty acid imines with the general formula R<3>C(NR')NR''R ''', in each case, if applicable, including their corresponding acids or bases, and combinations thereof. These surfactant structures are preferred from an application point of view and can also be produced by shorter and/or more energy-saving processes, for example compared to fatty alcohol or fatty amine derivatives. They are therefore more sustainable and economical. Surfactant B within the meaning of this application explicitly excludes biosurfactants comprising sophorolipid, rhamnolipid, trehaloselipid, mannosylerythritol lipid or cellobioselipid. These surfactants fall under Surfactants D of this application. In a preferred embodiment, the alkoxylated hydrophilic residues are of vegetable nature.

Anionic surfactants B: The inventive composition may contain one or more anionic surfactants B. The group B anionic surfactants defined in the claims which are based on C-18 vegetable oils as defined and whose hydrophilic part carries a water-soluble group such as carboxylate, sulfonate, sulfosuccinate, sulfamidocarboxylate, malonate, Succinate, sarcosinate, sulfate or phosphate groups, or their respective polyglycol ethers, each as salt or acid, and derivatives thereof. The anionic surfactants can be present in the form of their alkali metal, alkaline earth metal or ammonium salts, or as soluble salts of organic bases, such as mono-, di-, tri- or tetra-alkylammonium, or in the form of their corresponding acid.

For the purposes of this application, the preferred or particularly preferred surfactant structures described above are used as anionic surfactants, regardless of the choice of the other nonionic, cationic or amphoteric surfactants B.

The specific representatives of the anionic surfactants (B) are particularly preferably used, selected from the group comprising: salts of natural fatty acid mixtures (soaps), N-acylamino acid derivatives, acylated polypeptides, acyl isethionate, acyl lactylate, modified polyhydroxy fatty acid amides derivatized with anionic functional groups, such as carboxylate, sulfate, sulfonate or phosphate; sulfonated fatty acids, sulfonated fatty acid esters, sulfonated fatty acid glycerol esters, and mixtures thereof; Polyhydroxyalk(en)yl ethers and esters modified with anionic functional groups, e.g., carboxyl, etc., or derivatized alk(en)yl glycosides or alk(en)yl polyglycosides, for example alk(en)yl glucosides, citrate or tartrate. Optionally, these representatives can additionally be ethoxylated or propoxylated. Exemplary representatives of these very particularly preferred anionic surfactants (B), selected from the group comprising: salts of natural fatty acid mixtures (soaps), N-acylamino acid derivatives, acylated polypeptides, acyl isethionate, acyl lactylate, modified polyhydroxy fatty acid amides derivatized with anionic functional groups, such as carboxylate, sulfate, sulfonate or phosphate; sulfonated fatty acids, sulfonated fatty acid esters, sulfonated fatty acid glycerol esters, and mixtures thereof; Polyhydroxyalk(en)yl esters modified with anionic functional groups. These representatives have a hydrophilic part that can be produced entirely or predominantly from renewable raw materials and/or mineral raw materials and thus have advantages in terms of sustainability.

The representatives of the anionic surfactants B are extremely preferably selected from the groups based on C-18 vegetable oils, which are sulfur-free. Due to the shorter production routes, this selection is particularly advantageous in terms of sustainability and economy and low irritation potential. Exemplary representatives of these extremely preferred anionic surfactants B include: salts of natural fatty acid mixtures (soaps), N-acylamino acid derivatives, acylated polypeptides, acyl lactylate, modified polyhydroxy fatty acid amides derivatized with anionic functional groups, such as carboxylate; and their mixtures.

The particularly and/or very particularly preferred anionic surfactants B preferably consist of the respective surfactant mixture with hydrophobic parts consisting of at least two hydrocarbon radicals of different lengths and/or different degrees of saturation, particularly preferably a surfactant mixture with several different hydrocarbon chains that fractional distillation, and most preferably the distribution of hydrocarbon chains, in terms of chain length, corresponds to that found in natural oil. These are preferred from an application point of view and are more sustainable and economical due to less cleaning effort.

Soaps: in an inventively preferred embodiment, the agent contains one or more soaps made from natural fatty acid mixtures of group B, or their corresponding acids. The soaps B can be used in the form of their alkali metal, alkaline earth metal or ammonium salts, preference being given to the more soluble alkali metal or ammonium salts such as sodium, potassium, ammonium, mono-, di- or triethanolammonium salts or mixtures thereof. Depending on the degree of neutralization, the corresponding acids can also be present in the agent. As shown in the exemplary embodiments, those salts which are obtained from natural fatty acid mixtures derived from C-18 vegetable oils are used according to the invention because of their technical properties. In this case, fatty acid mixtures are used such as are obtained in the direct conversion of natural C-18 vegetable oils and, in particular, mixtures that are obtained without complex distillative fractionation steps. The agent can optionally contain glycerol, preferably between 0-50% by weight, particularly preferably 0-30% by weight and very particularly preferably 0-20% by weight, based on the total weight of the agent. The composition can also contain fatty acids, preferably less than 50% by weight, preferably less than 40% by weight and particularly preferably less than 25% by weight, based on the total weight of the composition. In the soap-containing embodiment, the agents preferably contain 0.001-50% by weight, preferably 0.01-40% by weight and particularly preferably 0.1-25% by weight soap; % by weight based on the total composition. Based on the weight of alkoxylated fatty acid alkyl esters A in the composition, the soap-containing embodiments preferably contain >2%, particularly preferably >10% and very particularly preferably >30% soap or the corresponding acid. In agents containing soft soap, it is preferable not to use any gel-forming agents such as gelian gum, among others. Sufficient thickening is achieved with the soap alone; additional thickening systems limit the flowability too much. In the embodiment variant containing soap, further thickening systems such as polyacrylate thickeners, xanthan gum, guar, alginates, carrageenans, carboxymethyl cellulose, bentonites, Wellan gum, carob and others are particularly preferably dispensed with. A preferred embodiment with soap is therefore free of gelian gum.

According to the invention, all representatives of the soaps B derived from C-18 vegetable oils can be used. In contrast to the medium-chain fatty acids usually used, the proportion of fatty acids with 16 and fewer carbon atoms in the soaps used according to the invention is preferably below 30% by weight, particularly preferably below 27% by weight and very particularly preferably below 17% by weight. based on the total weight of fatty acids and soaps in the composition. The soaps B used according to the invention also preferably have a proportion of saturated or unsaturated fatty acids with 20 and more carbon atoms of >0.01% by weight and particularly preferably >0.05% by weight and very particularly preferably >0.1% by weight and extremely preferably >= 0.2 wt.

In a particularly preferred embodiment, the agents are characterized in that they contain one or more soaps as the only anionic surfactants from group B. For application reasons, these variants particularly preferably also contain at least one further surfactant B derived from C-18 vegetable oils, selected from nonionic, amphoteric or cationic surfactants, more preferably selected from nonionic and amphoteric surfactants, most preferably nonionic surfactants.

Extremely preferred are the variants consisting of a combination of surfactant A with the following surfactants from group B: soap and at least one nonionic surfactant, preferably selected from the group of alkoxylated fatty acid amides, PEGylated vegetable oils, PEGylated fatty acids, polyhydroxy fatty acid amides and their combinations.

In a further alternative preferred embodiment, a soap-free composition has proven to be advantageous. Soap-free within the meaning of this application means that no additional soap or fatty acids are added to the agent and soap or fatty acids are introduced exclusively as impurities from other ingredients. This means that the ratio of soap or fatty acid to alkoxylated fatty acid alkyl ester(s) A in the soap-free embodiment of the agent is <0.3, preferably <0.1 and particularly preferably <0.05, and very particularly preferably <0.02 , each weight of soap to weight of surfactant A in the agent. In particular, the soap-free embodiment is preferred when agents are desired for a pH range in which soaps are not stable. Furthermore, the soap-free version is preferred if low-residue application, e.g. freedom from streaks, is desired. The soap-free embodiment may also be preferred if incompatibilities are expected, for example in compositions with cationic ingredients.

Exemplary preferred sulfonated anionic surfactants are sulfonated fatty acids, sulfonated fatty acid esters such as sulfonated fatty acid glycerol esters and sulfonated fatty acid methyl esters.

Amphoteric surfactants B: The inventive composition may contain one or more amphoteric surfactants B. Group B amphoteric surfactants which, as defined, are based on C-18 vegetable oils and carry both a positively and a negatively charged functional group (zwitterionic) and whose hydrophilic part forms or carries a water-soluble group, such as e.g. and carboxylate group or ammonium and sulfate group, etc. The amphoteric surfactants may be anionic or cationic, e.g., in the form of salts, or protonated at pH ranges beyond their isoelectric point. According to the invention, for example, the representatives of the following groups of amphoteric surfactants B are suitable, including: N-alk(en)yl betaines, such as alk(en)ylamido betaines, alk(en)ylamidopropyl betaines, alk(en)ylamido propyl dimethyl betaines, alk(en)ylamido propyl dimethylsulfobetaines , alk(en)ylamidopropylhydroxysultaine, alk(en)yl bis(2-hydroxyethyl)betaines, sulfobetaines, and others; N-Alk(en)ylglycinates, N-alk(en)ylaminopropionates, N-alk(en)yliminopropionates, alk(en)yl amphoglycinates, alk(en)yl amphoacetates, amine oxides, e.g. fatty amidopropyldimethylamine oxide, fatty bis(2-hydroxyethyl)amine oxide, fatty dimethylamine oxide ; Reaction products of the reaction of fatty acids or fatty acid esters with aminoethylethanolamine and subsequent reaction with chloroacetic acid (imidazoline-based amphoacetates), imidazoline amphoteres, e.g. imidazoline carboxylates, aminocarboxylic acids.

Surfactant(s) A and surfactant(s) B can be used in any ratio to one another, preferably in a ratio of 1:25 to 25:1.

Cationic surfactants B: The inventive composition may contain one or more cationic surfactants B. Cationic surfactants of group B which, as defined, are based on C-18 vegetable oils, are positively charged and whose hydrophilic part forms or carries a water-soluble group, such as e.g. ammonium function or salts thereof, for example primary, secondary, tertiary or quaternary alk(en)ylammonium salts of the formula (RI)(RII)(RIII)(RIV)N<+>X<->, in which RI to RVI are independently identical or different alk(en)yl radicals, branched and unbranched, saturated or unsaturated, unsubstituted, singly or multiply substituted, or H, where at least one of the radicals RI to RVI is derived from a C-18 vegetable oil and where X- is an anion. According to the invention, for example, ammonium salts with four organic radicals are suitable, at least one, preferably two, of the radicals representing a hydrocarbon chain which is derived from a C-18 vegetable oil. Cationic surfactants are preferably not used as the only surfactants in the composition. Because of their risk of skin irritation and their lower cleaning power, cationic surfactants are preferably used in this invention in combination with other surfactants, particularly preferably in combination with amphoteric or other nonionic surfactants. Since cationic surfactants have a low detergency, they are not used for the cleaning task, but preferably for additional washing effects such as conditioning, fixing or fabric rinses. Furthermore, compositions contain cationic surfactants because of their bactericidal effect. Because cationic surfactants tend to be less biodegradable, in a particularly preferred embodiment no cationic surfactants are used. For the purposes of this application, free from cationic surfactants means ≦0.5% by weight, preferably ≦0.2% by weight, particularly preferably ≦0.1% by weight and extremely preferably ≦0.02% by weight.

Variant combinations of surfactant A and surfactant B

In addition to the alkoxylated fatty acid alkyl esters A, the agent according to the invention contains at least one surfactant B selected from the group of anionic surfactants as defined in the claims, nonionic, amphoteric or cationic surfactants or combinations thereof. In a preferred embodiment, the agent according to the invention additionally contains at least one anionic surfactant as defined in the claims or amphoteric surfactant B. In a preferred embodiment, the agents are characterized in that they contain one or more soaps as the only anionic surfactants B, ie derived from C-18 vegetable oils. For application reasons, these variants particularly preferably additionally contain at least one further surfactant B derived from C-18 vegetable oils, selected from the nonionic, amphoteric or cationic surfactants, particularly preferably selected from the nonionic surfactants. In a further alternative preferred embodiment, a soap-free agent has proven to be advantageous. The soap-free embodiment preferably additionally contains anionic, amphoteric, cationic, nonionic surfactants or mixtures thereof. In another preferred embodiment, the agents contain at least one amphoteric surfactant B. This embodiment particularly preferably contains no anionic surfactants. This embodiment variant of the invention is characterized by very particular mildness with regard to skin and/or eye irritation and/or gentle treatment of materials and is therefore used particularly with sensitive groups of people or materials. This embodiment is therefore preferably used for washing and cleaning jobs on sensitive hard and flexible surfaces, fabrics and textiles, and very particularly for cleaning jobs involving skin contact, cleaning jobs at acidic to neutral pH values, cleaning sensitive fabrics. Further embodiments contain additional nonionic surfactants in the composition. The combination of alkoxylated fatty acid alkyl esters A and additional nonionic surfactants B, as disclosed in the examples, has an advantageous effect on the desired effects such as cleaning action, protection of materials, e.g. less color leaching or color transfer. The surfactant or surfactants B can be combined with the surfactant or surfactants A in any ratio.

Surfactants C: Other optional surfactants C8-C24

For further optional surfactants which can be freely combined with the agent according to the invention by a person skilled in the art, reference is made to the relevant specialist literature such as Richard J. Farn, Chemistry and Technology of Surfactants, Blackwell Publishing. It is decisive for the invention and its technical effects that surfactants A with surfactants B based on C-18 vegetable oils are predominantly present in the agent. A smaller proportion of other optional surfactants C can also be present in the agent without the desired effect of the invention being lost. These can be selected from the groups of anionic, nonionic, amphoteric or cationic surfactants. The hydrocarbon radicals of the hydrophobic part of the surfactants C can be saturated or unsaturated, substituted or unsubstituted, even or odd, linear, branched or cyclic, aliphatic, aromatic or araliphatic with 4-24 carbon atoms in the hydrocarbon chain, with the hydrophobic part being the Surfactants C is petrochemical or derived from natural, animal or vegetable oils, preferably comprising lauric or palmitic oils such as coconut oil, palm kernel oil, babassu, palm oil or animal fats such as tallow. The optional surfactants thus also explicitly include surfactants whose hydrophobic part, unlike surfactants A or B, is derived from the following fat or oil sources: (i) palm oil, palm kernel oil, coconut oil or other vegetable oils, fats and waxes with a predominance short to medium-chain saturated hydrocarbon radicals. (ii) Animal oils, fats and waxes, such as beef tallow, fish oil, lard, etc., with predominantly medium-chain saturated hydrocarbon radicals with ≤ 18 carbon atoms. (iii) petroleum (petrochemical e.g. based on Guerbet alcohols, benzyl alcohol, etc.) (iv) castor oil (hydroxy-substituted) The hydrophobic parts of these surfactants show clear technical differences to those of surfactants A and surfactants B, derived from C-18 vegetable oils, typically these are: - predominantly saturated, medium-chain hydrocarbon residues - proportions of branched and/or aromatic hydrocarbon residues - possible proportions of odd-numbered hydrocarbon residues Oleic acid and oleoyl- is usually obtained from tallow or palm fat. If no explicit information is given regarding the origin, e.g. sunflower oleoyl, oleic acid derivatives are assigned to surfactant group C.

Typical, exemplary representatives of the surfactants from group C are: Anionic: C12-18 fatty acid (sodium salt), palm kernel oil fatty acid, sodium cocoate, sodium salt of α-sulfonated C12-14 fatty acid methyl ester (MES), C9-13 alkylbenzene sulfonic acid (LAS). ), MEA Dodecylbenzenesulfonate, NaLAS, C8-18 Alkanesulfonate, Sodium Lauryl Ether Sulfate (2 or 3 EO) (SLES), MEA Laureth Sulfate, Sodium C10-16Pareth-2 Sulfate, Coco Sulfate, C16-18 Fatty Alcohol Sulfate, Sulfated Castor Oil, Sodium Iuryl Sulfate ( SLS), sodium lauroyl glycinate, etc. Nonionic: Palm methyl ester ethoxylate (10 EO) (MEE), C12/18 methyl ester ethoxylate (7EO), ethoxylated fatty alcohols (FAEO), e.g. C12-15 alcohol ethoxylate (7EO), C12-18 alcohol ethoxylate (7EO ), C12-14 Fatty Alcohol × 5 EO and 4 PO, Capryleth-4, C12-14 Pareth-7, C12-14 Pareth-12, Polyoxyethyl(6)isodecyl Alcohol, C12-14 Alkyl Polyglycoside (APG), Decyl Glucoside , lauryl glucoside, cocamide DEA, lauroylmethyl glucamide Amphoteric: C12/14 amine oxide, cocoamidopropyl betaine (CAPB), lauroamphocetate, cocosutaine, among others Cationic: DSDMAC (distearyldimethylammonium chloride), dihydrogenated Taiiow hydroxyethylmonium methosulfate, dipalmitoylethyl hydroxyethylmonium methosulfate, among others

The surfactant C in the context of this application is neither derived from C-18 vegetable oils nor a biosurfactant glycolipid of the group sophorolipid, rhamnolipid, trehaloselipid, mannosylerythritol lipid or celiobioselipid. Biosurfactants fall under surfactant D of this application.

Combinations with surfactant C

Surprisingly, the agents according to the invention show a comparable cleaning performance to conventional agents containing sulfuric surfactants, even without the use of sulfuric surfactants. For technical reasons, as explained in the exemplary embodiments, and for reasons of environmental protection, a preferred variant is free from all sulfuric surfactants from group C. The sulfur-free variants are generally characterized by the replacement of questionable sulfuric surfactants, such as sensitizing surfactants (e.g. laureth sulfate), surfactants that are toxic to the skin (e.g. lauryl sulphate), sulphurous surfactants that are toxic to humans (e.g. alkylbenzene sulphonate) and/or strongly irritating to the eyes (e.g. laureth sulphate) due to group B surfactants which tend to be less irritating and toxic thanks to a significantly improved toxicological profile and reduced irritation potential. The alkoxylated fatty acid alkyl ester(s) A is/are preferably present in a ratio of C/Sulphur: A<2:1, more preferably C/Sulphur: A<1:1, even more preferably C/Sulphur: A<1:2 particularly preferably C-sulphur: A <1:5, very particularly preferably the agent is free from sulfur surfactants C-sulphur and extremely preferably the entire agent is free from sulfur surfactants from groups B and C. Likewise, the water-polluting surfactants of the phosphate and phosphonate groups can be dispensed with without compromising cleaning performance. Another preferred embodiment is phosphate and phosphonate free.

Another preferred variant is free from alkyl polyglycosides (APG), such as decyl glucoside, coco glucoside, lauryl glucoside, C8-10 alkyl polyglucoside, caprylyl/myristyl glucoside, etc. This class of surfactants is also highly irritating to the eyes and, for toxicological reasons, is only used to a small extent or not used at all. The alkoxylated fatty acid alkyl ester(s) A to the APG(s) from group C (CAPG) is preferably present in a ratio of CAPG:A<2:1, more preferably CAPG:A<1:1, particularly preferably CAPG:A<1:5. most preferably the agent is free from group C APGs. This embodiment variant can contain sulfuric surfactants C-sulphur or, particularly preferably, also be free of sulfuric surfactants C-sulphur. Exemplary embodiments of these variants are disclosed in the application.

Preferred embodiment variants of the agent contain surfactants A and surfactants B, each derived from C-18 vegetable oils. The proportion of surfactants derived from C-18 vegetable oils is then >50% by weight, preferably >66.7% by weight, particularly preferably >75% by weight. % by weight based on the total weight of surfactants in the composition. The particularly preferred embodiment of the agent contains surfactants A and surfactants B, each derived from C-18 vegetable oils and is free of surfactants C, the content of surfactants derived from C-18 vegetable oils is 100%.

Surfactants D: Biosurfactants

Surprisingly, it was found that biosurfactants D of the classes rhamnolipids, sophorolipids, mannosylerythritol lipids, trehalose lipids and cellobiose lipids promote the undesired leaching of colors (see exemplary embodiment). In order to protect the colors, agents without biosurfactants are technically preferred. Other reasons for not using biosurfactants are the high costs of these surfactant classes and the possible use of genetically modified organisms (GMO) for the production of some biosurfactant classes. GMO is controversial.

The inventive agents contain a total of less than 0.3% by weight, preferably <0.2% by weight, particularly preferably <0.1% by weight, of glycolipid biosurfactants D from the groups: rhamnolipids, sophorolipids, mannosylerythritol lipids, Trehalose lipids, contain cellobiose lipid. The agents are particularly preferably free from the glycolipid biosurfactants D, i.e. the total amount of all biosurfactants according to the above list is ≦0.01% by weight, very particularly preferably ≦0.001% by weight, given as the sum of all glycolipid biosurfactants present in the agent, based on the weight of the agent, extremely preferably no detectable amounts of biosurfactants D are contained in the agent. The surfactant ratio of biosurfactant D to alkoxylated fatty acid alkyl ester A is preferably less than 0.14:1, particularly preferably <0.07:1, and the composition is very particularly preferably biosurfactant-free.

Another advantage of the inventive agents is that they are low-foaming. Low-foaming agents are preferred for machine applications, which are achieved from a content of glycolipid biosurfactants of <0.3% by weight of biosurfactants, based on the entire agent.

Other optional surfactants E: There may be other optional surfactants in the composition that have not been defined in the previous groups, such as silicone surfactants. All surfactants not defined under A, B, C or D fall under surfactants E..

Total surfactant composition: The inventive agent is characterized in that the proportion of surfactants A and B predominates, it is preferred that the surfactant or surfactants A are also derived from a C-18 vegetable oil and thus their proportion predominates. The desired effect is achieved through the combination of alkoxylated fatty acid alkyl esters with predominantly long-chain unsaturated hydrocarbon radicals of the surfactants B.

The ratio of surfactants C to surfactants A and B is calculated as follows: m(C)=m(C)/[m(A)+m(B)+m(C)]×100%

And m(C) in the inventive composition is < 50% by weight, preferably < 33.3% by weight and more preferably < 25% by weight.

Where m(A), m(B) and m(C) each represent the absolute amounts in kg or the relative amounts in % by weight, based on the total composition, of the surfactant(s) A, B and C and where m(C) can be zero and where m(D) + m(E) are considered negligibly small. The variant with m(C)=0, in particular with m(C)+m(D)+m(E)=0, is particularly preferred. In this particularly preferred variant, which is disclosed as an example in the exemplary embodiments, all additional surfactants are present derived from C-18 vegetable oils, in an extremely preferred embodiment the surfactant or surfactants A is also derived from C-18 vegetable oils. Thus, the total proportion of surfactants in the composition which are derived from C-18 vegetable oils is preferably ≧50% by weight, more preferably ≧33% by weight and even more preferably ≧25% by weight and the composition most preferably contains only surfactants derived from C-18 vegetable oils.

[0110] Further aspects of the present invention emerge from the following examples and the appended patent claims.

Examples:

Overall cleaning performance and, if applicable, cleaning performance on specific stains is measured relative to the reference in accordance with the industry standard (A.I.S.E. recommendation November 2013). Unless otherwise stated, the cleaning effect, color protection or leaching and color transfer are each determined coiorimetrically relative to the reference. The leaching or color protection is determined by the colorimetric determination of the wash liquor after exposure to colored test textiles (representative wash conditions, 40° C., csurfactant=0.6 g/l). Color transfer is determined coiorimetrically by measuring the degree of whiteness on white cotton after the washing process with colored test textiles.

Color protection and reduced color transfer through the inventive binary means

Here as an example with the following representatives of the individual surfactant groups: Surfactant A=ethoxylated fatty acid methyl ester (7 EO) from rapeseed fatty acids, surfactant B anionic=sodium olive oil glutamate, as a reference=sodium cocoglutamate, surfactant A, nonionic=glycereth-8 ester of peach kernel oil, as reference = glycereth-7 ester of coconut oil, surfactant B amphoteric = amidopropyl betaine of olive oil, as reference = amidopropyl betaine of coconut oil; Surfactant A, cationic = amidopropyl betaine cation of olive oil (pH=2.2), for reference = amidopropyl betaine cation of coconut oil (pH=2.2); Concentration data based on % by weight of active; Experiments with a surfactant ratio of 1:1 in each case, concentration 0.6%, 40°C.

Result: All inventive surfactant combinations (alkoxylated fatty acid alkyl esters A with C-18 surfactants B show increased color protection compared to pure surfactant A and also compared to analogous mixtures with coconut-based reference surfactants (C12-C18) (Table 1).

Result: In comparison to analogous mixtures with coconut-based reference surfactants, all of the agents according to the invention exhibit significantly reduced color transfer (Table 2). Light-colored fabrics are less discolored in the presence of colored fabrics.

Detergents and cleaning agents with alkoxylated fatty acid alkyl esters A and at least one C18 surfactant B

Here as an example with the following representatives of the individual surfactant groups: Surfactant A=ethoxylated fatty acid methyl esters (7 EO) from rapeseed fatty acids, surfactant B=potassium soap (C18) from C-18 vegetable oil fatty acids, e.g. linseed; B Nonionic surfactant (C-18) Ethoxylated fatty acid amide (4 EO) from rapeseed fatty acids, Surfactants C = potassium soap C12-C18 from coconut oil, sodium laureth sulfate (SLES), decyl glucoside (APG), concentrations based on wt.% active.

The cleaning effect, as shown here as an example, improves at the same total surfactant concentration by using C-18 surfactants (surfactants B) instead of medium-chain surfactants (surfactants C). Surprisingly, there is a significant improvement in fat removal. It is particularly surprising that regardless of the nature of the C-18 surfactant (surfactant B) - here in the example regardless of the ionic character - the agents according to the invention with an additional surfactant B with a high proportion of long-chain unsaturated fatty acids a) have better color protection and reduced offer leaching of the colors and b) reduce the color transfer to light-colored textiles in the wash liquor.

The cleaning effectiveness and inhibition of color transfer of the agent with C-18 soap (Surfactant B) with a partial replacement of a nonionic medium-chain surfactant C with an additional nonionic C-18 surfactant B further increases (Table 4).

Amount ratio to surfactant group C, especially sulfur surfactants

The technical effect depends on the ratio of the fatty acid chain lengths and the degree of saturation of the surfactants used. The color transfer inhibition as a function of the proportion of predominantly medium-chain saturated surfactants C is shown in drawing 1. The proportion of surfactant C is given in relation to the total surfactant concentration (A+B+C) x 100%, shown here as an example with surfactant C: sodium laureth sulfate, surfactant A: ethoxylated fatty acid methyl ester (7 EO) from rapeseed fatty acids, and surfactant B: ethoxylated Fatty acid amide (4 EO) from rapeseed fatty acids. The proportion of surfactant C is varied compared to a 1:1 mixture of surfactant A with surfactant B.

Drawing 1 shows the whiteness of the washed textile samples as a measure of undesired color transfer (0=whiteness of the reference=no discoloration; bar height indicates the degree of discoloration due to color transfer).

Result: The strongest, undesired color transfer takes place with the reference, the pure surfactant C=100%. Up to a proportion of 50% surfactant C, the color transfer effect decreases almost linearly. With a proportion of < 50% surfactant C, the color transfer is reduced by more than 80% compared to the reference, < 33.3% the color transfer becomes asymptotic. From a technical point of view, quantitative ratios of C/(A+B+C)×100% are therefore inventively preferred <50%, in particular <33.3%, very particularly <25%. The best result is obtained when no surfactants C are present in the composition and is therefore particularly preferred. Preferred variants of the agents therefore have low (i.e. (C-sulfur):(A)<2:1, preferably <1:1, especially preferably <1:2 and very especially preferably <5:1) to no proportions of sulfur surfactants Csulphur. The desired inhibition of color transfer with decreasing content of surfactants C, in particular sulfuric surfactants, is confirmed in detergent and cleaning agent products. With regard to reduced color transfer, agents with low proportions or without APG and/or sulfur surfactants are preferred (Table 5). All inventive agents show a higher washing performance than the reference with a proportion of surfactants C ≥ 50%.

concentrates

Reference 2 (see Table 7) was used at a dosage of 55 ml and compared to the overall washing results of the inventive agents from Table 5 (E1, E3, E4, E5) at a dosage of 25 ml. Surprisingly, it was found that the agents according to the invention have such a high cleaning performance that they can be used as concentrates in a smaller dosage, even with hard water. The dosage of the inventive agent can be reduced by about 50% with the same overall cleaning performance. A good cleaning performance of the inventive agents can be observed in particular on greasy stains.

Mixtures - influence composition of fatty acids

It is shown by way of example that the color transfer of a dye onto white cotton fabric in the washing process is particularly effectively inhibited with mixtures of C-18 fatty acids (drawing 2). Result: The inventive combination of surfactant A (alkoxylated rapeseed methyl ester, 7 EO) with a surfactant B consisting of a mixture of fatty acids (potassium salts of linseed fatty acids) shows less leaching and stronger color transfer inhibition (drawing 2) than the two reference mixtures of surfactant A with a ) Potassium salt of coconut fatty acids C12-C16, b) Potassium salt of oleic acid. If another non-ionic surfactant B is added, e.g. ethoxylated fatty acid amide (4 EO) from rapeseed oil, the color transfer inhibition is further increased in an unpredictable manner.

Influence of biosurfactants

The degree of color leaching in the presence of biosurfactants is shown in Figure 3. Biosurfactant = sophorolipid, surfactant A: ethoxylated rapeseed methyl ester, surfactant B: ethoxylated fatty acid amide based on rapeseed, concentration ratios according to Table 6. Surfactant A and surfactant B are each used in a ratio of 1:1 with a constant total surfactant concentration of 3% by weight and variable biosurfactant concentrations of 1% by weight to 0% by weight used, % by weight based on the composition as a whole.

The relative measurement results, based on the biosurfactant-free agent as the standard (=zero line), are shown in drawing 3. Result: Leaching is significantly reduced (by approx. 75%) from a total content of <0.3% by weight of biosurfactant. At < 0.2% by weight of biosurfactant, leaching is only minimal and the curve flattens out. The least leaching is obtained when no biosurfactants are present in the composition. In order to obtain color-preserving agents with low color transfer, biosurfactants may only be present in the agent to a small extent or preferably not at all. Consequently, agents with a low biosurfactant content are required according to the invention, preferably without any biosurfactants.

Foam: An additional advantage of the low-biosurfactant (<0.3% by weight, preferably <0.2% by weight) to biosurfactant-free agents is that these agents are low-foaming. Foam formation starts at a biosurfactant concentration > 0.3% by weight and increases rapidly with increasing concentration of biosurfactants.

cleaning performance+toxicity

Table 7 shows the comparison of the inventive agents in comparison to a commercially available detergent (Ref 2). The following composition was chosen as the detergent base: 1.5% by weight of citric acid, 3% by weight of 96% ethanol, 5% by weight of propylene glycol, 5% by weight of potassium hydroxide, with deionized water to 100. The test detergents were each adjusted to pH 8-9 with lactic acid. The washing tests were carried out with a dosage of 25 ml of the washing solutions in hard water.

Result: It can be seen from Table 7 that all the inventive agents form less foam than the reference and also show a lower foam stability than the reference. The overall cleaning performance of the inventive agents is better than that of the reference. All of the inventive agents surprisingly show less color leaching, as well as less color transfer to light colored fabrics than the reference.

The agents according to the invention show an increased viscosity that does not require any additional thickening, in contrast to the low-viscosity reference detergent.

The hazard potential of the different compositions was also evaluated. The classification according to ECHA (European Chemical Agency) was used. The hazard potential for the individual areas (eye irritation, skin irritation, water hazard) was weighted according to the classification category, i.e. category 1: multiplication factor 3, category 2: multiplication factor 2, category 3: multiplication factor 1. Oral tox is weighted more heavily due to the relevance of poisoning cases: Category 1: multiplication factor 5, Category 2: multiplication factor 4, Category 3: multiplication factor 3, Category 4: multiplication factor 2. The weighting is carried out by the concentration times the multiplication factor.

In Table 7 it can be clearly seen that the inventive agents mentioned here based on their surfactants are all to be classified as non-irritating to the eyes (value=0). In contrast, the eye irritation of the reference can be classified as significant. This is also the case for almost all other commercial detergent compositions - especially for concentrates. You also get a significantly improved eco-profile compared to the reference and an improvement, albeit less, in relation to skin irritation.

In summary, in the exemplary embodiments considered here (Table 7), a reduction in the overall risk potential of 78-96% is obtained.

Detergent highly concentrated

In Table 8 detergent high concentrates, e.g., for the product form of PODs are shown. Compared to conventional detergent PODs, shown as an example in reference 3, the concentration of questionable surfactants with oral toxicity, irritation of the mucous membranes (e.g. eyes), water damage and possibly skin irritation can be significantly reduced using the inventive agents. In the case of the preferred embodiments, here combined sulfate-free and concentration of surfactant C=0, even label-free agents can be obtained (according to Regulation (EC) No. 1272/2008 (CLP)). Dosage 25 ml.
