The funds are also characterized by improved sustainability, a lower toxicological hazard potential and a lower impact on the environment.

Description

Technical object

This application relates to agents comprising at least one alkoxylated fatty acid alkyl ester and at least one further surfactant class, which is based on fatty acids from vegetable oils and has a high proportion of long-chain and mostly unsaturated hydrocarbon chains. Another subject matter is its use as, for or for the production of washing and cleaning products, the use of the agent according to the invention as a concentrate, the use of the agent to reduce its risk potential and the use of the agent to protect colors or materials, as well as a method for use . The agents show a lower toxicological and ecotoxicological hazard potential, increased sustainability and a lower 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 previous publications on fat, the solubility in water is good (e.g. EP 0997521). Alkoxylated fatty acid alkyl esters are combined with other surfactants that have less favorable environmental behavior and / or a potential health hazard. This is accepted in order to obtain inexpensive, broadly 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 are used in combination with alkoxylated fatty acid alkyl esters, which are based on fatty acids which are predominantly saturated and carry hydrocarbon residues with 8-18 carbon atoms, such as those obtained from coconut oil or palm kernel oil. Examples of surfactants that are usually combined with alkoxylated fatty acid esters are C12-C18-alkyl ether sulfates, C12-C18-alkyl sulfates, C12-C18-alkylbenzenesulfonates, olefin sulfonates, C8-C18 alkoxylated fatty alcohols (e.g. EP 3144 373) or alkyl polyglycosides (e.g. US Pat. No. 5,753,606) ). These surfactants prove to be robust over a high pH range, compatible with almost all common ingredients and therefore flexible in use with good cleaning performance against all common types of dirt. However, due to the finite nature of crude oil and the destruction of the tropical rainforest for the cultivation of tropical oil plants and the associated climate problems, it is desirable to use more and more surfactants based on more sustainable fatty acid sources. In addition, colored textiles or surfaces are affected by high washing and cleaning performance. Often an undesirable graying effect due to color transfers to light-colored textiles has to be accepted. The problem of color leaching and its transfer is solved by additives such as PVP or color transfer inhibitors. Disadvantages are undesirable side effects of these components, such as the fixation of stains on the fabric, as well as disadvantages in terms of costs and the environment. Many common surfactants are also declared to be 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 alkyl polyglycoside or glucoside cause serious eye damage. Accident reports regarding swallowing and eye burns are increasing, especially with the colorful detergent pods. It is therefore desirable to produce an agent with a lower hazard 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. Biosurfactants have been offered as alternative surfactants in recent years, which are characterized by low toxicology and good environmental behavior, as well as good cleaning performance. The commercial use of biosurfactants is limited due to the high cost of these special 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 that are characterized by good, extensive environmental behavior, reduced CO2 footprint and low toxicological hazard potential. For sustainability considerations, 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, i.e. not of animal origin. This is technically demanding, since most vegetable oils, such as those from European cultivation, cannot sufficiently obtain the otherwise desired lauric acid (C12). Instead, European vegetable oils have a high proportion of unsaturated, long fatty acid residues ≥ C18, which in the products have completely new properties such as solubility, foam, stability, cleaning performance, wettability, compatibility, etc. entail. Furthermore, it was a preferred goal to use one and the same surfactant mixture over a broad 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 objects mentioned. Surprisingly, it was found that the detergents and cleaning agents according to the invention are capable of washing and cleaning in a manner that is gentle on the material and color, in addition to good cleaning performance. Colors are better preserved during the cleaning process, bleeding is reduced and materials are spared. In addition, the color transfer of the colors dissolved in the washing liquor to light-colored materials during the washing and cleaning process is also unexpectedly reduced. Additives for color fixation and color transfer inhibitors can be dispensed with. Due to the good, yet gentle cleaning performance, the agents are suitable for a wide range of applications, such as for cleaning surfaces and textiles, especially dyed 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 aquatoxicity and lower CO2 footprint compared to conventional agents according to the prior art. The inventive agents also have a favorable toxicological profile, especially with regard to oral toxicity, dermal toxicity, skin irritation, eye irritation and allergen 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, represent a low risk potential for humans and the environment. From a technical point of view, low-foam applications are often desirable. Surprisingly, the compositions according to the invention develop little foam, as are preferred from a technical point of view, for example for machine application. There is no need to use expensive and environmentally harmful defoaming agents. Furthermore, the agents can be rinsed off easily. As a result, the products based on the agents according to the invention can be easily rinsed off, in particular also in cold water applications. The agents can preferably be removed in a single rinse process (“one-rinse detergents”). This enables an ecological and water-saving method for using the inventive agents, in particular for machine cleaning of surfaces and textiles. In the compositions according to the invention, the alkoxylated fatty acid alkyl esters can be used as primary surfactants and, as such, develop their advantageous properties in combination with co-surfactants as described in the application. The agent according to the invention is also disclosed in a preferred preservative-free embodiment.

The detergents have such a good cleaning effect that in preferred embodiments enzymes and / or bleaches can be dispensed with. Surprisingly, the inventive agents can also be used as high concentrates. They are therefore technically preferred for high concentrates, ultra concentrates, sachets and pods. The inventive agents are stable as high concentrates; if necessary, further more sensitive ingredients can be spatially separated for storage and sale in these applications (compartments). This is particularly the case in embodiments with bleach. It is particularly advantageous that the agents according to the invention can be used over a wide pH range, and thus allow a wide range of products and applications. Another advantage of the invention is that, unlike in commonly used anionic surfactant systems such as e.g. Sodium Lauryl Sulphate, Sodium Laureth Sulphate or Sodium Alkylbenzene Sulphonate, the agents according to the invention are less sensitive to hard water and therefore there is no reduction in the dirt-carrying capacity in the presence of calcium or magnesium ions. Sulfur surfactants can irritate the skin and mucous membranes. In a preferred embodiment, the agents are produced without medium-chain sulfur surfactants, in particular without any sulfur surfactants, and thus support the “sulfate-free” trend. Nonionic surfactants such as Decyl glucoside or biosurfactants, which are usually used for hard water, can thus be minimized or even excluded. Due to the high efficiency, even in hard water, this allows a lower dosage of the agent, which means that 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 adding the agent as a whole, also from dosing systems, or from separate compartments (e.g. pods) with an in-situ production of the agent at the point of use. In a further subject matter of the invention, the invention is directed to the use of the agents for the production of or as detergents and cleaning agents. In a further subject matter of the invention, the invention is directed 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, gel-like, pasty, foam-like or solid form. The preferred embodiment is liquid, gel-like, pasty or foam-like. 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 above-mentioned concentrates. This can be in the form of solid products (e.g. tabs, tablets, pastilles, extrudate, etc.), in the form of cloths made of woven, knitted or knitted textiles, made of paper, wadding, felt or fleece (e.g. made of polypropylene, polyester or viscose ) and their composite materials, which are 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 separated compartments for individual ingredients (e.g. bleach, enzymes, etc.). The envelope can also be in the form of primary packaging, e.g. be made of plastic or glass, or a manual or mechanical dosing device or a cartridge. Another subject matter of the invention is the use of the agent as a washing or cleaning product for biological or natural surfaces, hard or flexible surfaces, as well as for textiles, carpets or natural fibers. Another preferred use, independent of the previous one, is cleaning and washing textiles, carpets or natural fibers.

Surfactant (B) based on fatty acids from C18 vegetable oils

The compositions according to the invention additionally contain at least one further surfactant (B) based on C18 vegetable oils, as defined above. The hydrophobic part of the surfactant, derived from C-18 vegetable oils, is essential for the invention. The agent contains at least one further surfactant selected from the group comprising anionic, nonionic, cationic and amphoteric surfactants, the hydrophobic part of the surfactant or surfactants being an aliphatic, saturated, mono- or polyunsaturated hydrocarbon radical with 6-24 carbon atoms derived from a C- 18-vegetable oil, the hydrocarbon radical or preferably the mixture of hydrocarbon radicals of the surfactant (s) (B) being predominantly long-chain and unsaturated, the proportion of linear, even-numbered hydrocarbon radicals with 18 and more carbon atoms above 60% by weight, preferably above 72 % By weight and most preferably greater than 77% by weight; and wherein the proportion of linear, even-numbered, unsaturated hydrocarbon radicals, i. with one or more internal double bonds, above 55% by weight, preferably above 65% by weight and particularly preferably above 72% by weight, in each case based on the total weight of hydrocarbon residues of the hydrophobic part in the surfactant or surfactants (B) .

All surfactants (B) are very particularly preferably in the form of a mixture of hydrocarbon radicals. Such preferred mixtures of one or more surfactants (B) have, in addition to better economy and better ecological balance (no or few complex cleaning steps), technical advantages in the agents.

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

The soaps (B) can be used in the form of their alkali metal, alkaline earth metal or ammonium salts; preference is given to the more soluble alkali metal or ammonium salts, such as, for example, Na, K, 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 C18 vegetable oils are used according to the invention because of their technical properties.

Further embodiments contain additional nonionic surfactants in the agent. The combination of alkoxylated fatty acid alkyl esters (A) and additional nonionic surfactants as disclosed in the exemplary embodiments have an advantageous effect on the desired effects such as cleaning action, material protection e.g. less color leaching or color transfer.

(ii) animal oils, fats and waxes, such as beef tallow, fish oil, lard, etc., with predominantly medium-chain saturated hydrocarbon residues 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 significant technical differences to those of surfactants (A) and (B), derived from C-18 - Vegetable oils, typically these are: predominantly saturated, medium-chain hydrocarbon residues Shares of branched and / or aromatic hydrocarbon radicals Possible proportions of odd-numbered hydrocarbon residues Oleic acid and oleoyl are usually obtained from tallow or palm fat. Unless explicitly stated 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 the α-sulfonated C12-14 fatty acid methyl ester (MES), C9-13 alkylbenzenesulfonic acid (LAS), MEA dodecylbenzenesulfonate, NaLAS, C8-18 alkanesulfonate, sodium lauryl ether sulfate (2 or 3 EO) (SLES), MEA laureth sulfate, sodium C10-16 pareth-2 sulfate, coconut sulfate, C16-18 fatty alcohol sulfate, sulfated castor oil, Sodium Lauryl Sulphate (SLS), Sodium Lauroyl Glycinate, among others Nonionic, palm methyl ester ethoxylates (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 x 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.

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

Combinations with (C)

Surprisingly, the agents according to the invention show a comparable cleaning performance to conventional agents with sulfur surfactants, even without the use of sulfur surfactants. For technical reasons, as detailed in the exemplary embodiments, as well as for reasons of environmental protection, a preferred variant is free from all sulfur surfactants from group C. The sulfur-free variants are generally characterized by the replacement of questionable sulfur surfactants, such as e.g. Sensitizing surfactants (e.g. laureth sulfate), skin-toxic surfactants (e.g. lauryl sulfate), human toxic (e.g. alkylbenzenesulfonate) and / or highly irritating sulfur surfactants (e.g. laureth sulfate) due to the less irritating and toxic surfactants of group (B) due to a significantly improved toxicological profile and reduced Irritation potential. The alkoxylated fatty acid alkyl ester (s) (A) and the sulfur surfactant (s) (C) are preferably in an amount ratio of (C-sulfur): (A) <2: 1, more preferably (C-sulfur): (A) <1: 1, even more preferably ( C-sulfur): (A) <1: 2, particularly preferred (C-sulfur): (A) <1: 5, very particularly preferably the agent is free from sulfur surfactants (C) and most preferably the entire agent is free from sulfur surfactants (B) and (C). The water-polluting surfactants of the phosphate and phosphonate groups can also be dispensed with without compromising on cleaning performance. Another preferred embodiment is free of phosphate and phosphonate.

Another preferred embodiment variant is free from alkyl polyglycosides (APG), such as e.g. Decyl glucoside, cocoglucoside, lauryl glucoside, C8-10 alkyl polyglucoside, caprylyl / myristyl glucoside and others This class of surfactants is also very irritating to the eyes and, for toxicological reasons, is used only to a limited extent or not at all.

The alkoxylated fatty acid alkyl ester (s) (A) and the APG (s) (C) are preferably in a quantitative ratio of (CAPG): (A) <2: 1, more preferably (CAPG): (A) <1: 1, particularly preferred (CAPG): (A) <1: 5, very particularly preferably the agent is free from APGs (C). This variant can contain sulfur surfactants (C) or, particularly preferably, additionally be free from sulfur surfactants of group (C). Embodiments of these variants are disclosed in the application.

Preferred variants of the agent contain surfactants (A) and (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 agent. The particularly preferred variant of the agent contains surfactants (A) and (B), each derived from C-18 vegetable oils and is free from surfactants (C), the content of surfactants derived from C-18 vegetable oils is 100%.

(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 therefore technically preferred. Other reasons for not using biosurfactants are the high costs of these classes of surfactants, as well as the possible use of genetically manipulated organisms (GMO) for the production of some classes of biosurfactants. GMO is a controversial issue.

The inventive agents contain a total of less than 0.3 wt .-%, preferably <0.2 wt .-%, particularly preferably <0.1 wt .-% glycolipidic biosurfactants (D) of the groups: rhamnolipids, sophorolipids, Contain mannosylerythritol lipids, trehalose lipids, cellobiose lipid. The agents are extremely preferably free from the glycolipidic 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,% by weight stated as the sum of all glycolipidic biosurfactants present in the agent based on the weight of the agent, It is extremely preferred that the agent does not contain any detectable amounts of biosurfactants (D). The surfactant ratio of biosurfactant to alkoxylated fatty acid alkyl ester is preferably less than 0.14: 1, particularly preferably <0.07: 1, and very particularly preferably the agent is free of biosurfactants.

Another advantage of the inventive agents is that they are low in foam. For machine applications, low-foaming agents are preferred which are obtained from a glycolipidic biosurfactant content of <0.3% by weight of biosurfactants based on the total agent.

(E): Further optional surfactants E: Further optional surfactants can be present in the agent which were not defined in the previous groups, for example silicone surfactants. All surfactants not defined under (A), (B), (C) or (D) come under surfactants (C).

Total surfactant composition: The inventive agent is characterized in that the proportion of the 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 share 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 the surfactants (C) to the surfactants (A) and (B) is calculated according to: (C) = (C) / [(A) + (B) + (C)] × 100% And (C) in the inventive agent is <50% by weight, preferably <33.3% by weight and more preferably <25% by weight.

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

Embodiments:

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 colorimetrically relative to the reference. The leaching or the color protection is determined by the colorimetric determination of the washing liquor after it has acted on colored test textiles (representative washing conditions, 40 ° C., surfactant = 0.6 g / l). Color transfer is determined colorimetrically by measuring the degree of whiteness on white cotton after the washing process with colored test textiles.

The cleaning effect, as shown here by way of example, improves with the same total surfactant concentration by using C18 surfactants (B) instead of medium-chain surfactants (C). Surprisingly, a significant improvement in fat removal can be observed. It is particularly astonishing that regardless of the nature of the C18 surfactant (B) - in this example regardless of the ionic character - the inventive agents with an additional surfactant (B) with a high proportion of long-chain unsaturated fatty acids a) provide better color protection and reduced leaching of the colors and b) reduce the transfer of color to light-colored textiles in the wash liquor.

The cleaning effect and inhibition of color transfer of the agent with C-18 soap (B) when a nonionic medium-chain surfactant (C) is partially replaced by an additional nonionic C18 surfactant (B) increases further (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 dye transfer inhibition as a function of the proportion of the predominantly medium-chain saturated surfactants (C) is shown in drawing 1. The proportion of surfactant (C) based on the total surfactant concentration (A + B + C) x 100% is specified, 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 degree of whiteness of the washed textile samples as a measure of undesired color transfer (0 = degree of whiteness of the reference = no discoloration; the height of the bar indicates the degree of discoloration due to color transfer).

Result. The strongest, undesirable color transfer occurs with the reference, the pure surfactant (C) = 100%. The color transfer effect decreases almost linearly up to a proportion of 50% of surfactant (C). 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 is asymptotic. From a technical point of view, quantitative ratios of (C) / (A + B + C) × 100% <50%, in particular <33.3%, very particularly <25% are therefore inventively preferred. The best result is obtained when no surfactants (C) are present in the agent and is therefore particularly preferred. Preferred embodiment variants of the agents therefore have low (ie (C-sulfur): (A) <2: 1, bev. <1: 1, especially bev. <1: 2 and very especially bev. <5: 1) to no proportions on sulfur surfactants (C). The desired inhibition of color transfer with a decreasing content of surfactants (C), in particular sulfur 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 with a dosage of 55 ml and compared with the total washing results of the inventive agents from Table 5 (E1, E3, E4, E5) in a dosage of 25 ml. Surprisingly, it was found that the inventive agents have such a high cleaning performance that they can be used as concentrates in a lower dosage, even with hard water. The dosage of the inventive agents can be reduced by approx. 50% with the same overall cleaning performance. A good cleaning performance of the inventive agents can be determined in particular on grease stains.

Mixtures - Influence composition of fatty acids

It is shown by way of example that the color transfer of a dye to 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 greater color transfer inhibition (drawing 2) than the two reference mixtures from (A ) with a) potassium salt of coconut fatty acids C12-C16, b) potassium salt of oleic acid. When adding another nonionic surfactant (C), e.g. Ethoxylated fatty acid amide (4 EO) from rapeseed oil, the color transfer inhibition is further intensified in an unpredictable way.

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 are used,% by weight based on the total agent.

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

Foam: An additional advantage of the low-bio-surfactant (<0.3% by weight, especially <0.2% by weight) to bio-surfactant-free agents is that these agents are low in foam. Foaming begins at a biosurfactant concentration> 0.3% by weight and increases rapidly as the biosurfactant concentration increases.

Cleaning performance + toxicity

Table 7 shows the comparison of the inventive agents in comparison with a commercially available detergent (Ref 2). The following composition was chosen as the detergent base: 1.5% by weight citric acid, 3% by weight 96% ethanol, 5% by weight propylene glycol, 5% by weight 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: Table 7 shows that all of 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 and less color transfer to light-colored textiles than the reference.

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

Furthermore, the hazard potential of the different compositions was 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 done by the concentration multiplied by the multiplication factor.

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

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

High concentrate detergents

In Table 8, detergent high concentrates, e.g. shown for the product form of PODs. Compared to conventional POD detergents, exemplified 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 with the aid of the inventive agents. In the case of the preferred embodiments, here combined sulfate-free and concentration of surfactant (C) = 0, agents that are not subject to labeling can even be obtained (according to Regulation (EC) No. 1272/2008 (CLP)). Dosage 25 ml.
