Agent for coloring keratin material containing aminosilicone, color-providing compound and an addition product of C1-C6 alkylene oxide(s) with the esters of fatty acids and aromatic alcohols

Description

[0001] The present application relates to an agent for coloring keratinic material, in particular human hair, which contains at least one amino-functionalized silicone polymer (a1), at least one color-imparting compound (a2) and at least one addition product of C 1 -C 6 alkylene oxide(s) onto the esters of fatty acids and aromatic alcohols.

[0002] A second subject matter of this application is a method for dyeing keratinic material, in particular human hair, wherein an agent of the first subject matter of the invention is applied to the keratinic material, allowed to act and then washed out again with water.

[0003] Altering the shape and color of keratinous material, especially human hair, represents an important area of ​​modern cosmetics. Depending on the coloring requirements, hair coloring specialists are familiar with various coloring systems. For permanent, intense colorings with good fastness properties and good gray coverage, oxidation dyes are typically used. Such dyes contain oxidation dye precursors, so-called developer components, and coupler components, which, under the influence of oxidizing agents such as hydrogen peroxide, form the actual dyes. Oxidation dyes are characterized by very long-lasting coloring results.

[0004] When using direct dyes, the fully formed pigments diffuse from the dyeing agent into the hair fiber. Compared to oxidative hair coloring, the colors obtained with direct dyes are less durable and wash out more quickly. Colorations with direct dyes typically remain on the hair for between 5 and 20 washes.

[0005] The use of color pigments is known for temporary color changes on hair and / or skin. Color pigments are generally understood to be insoluble, color-imparting substances. These are present undissolved in the form of small particles in the coloring formulation and are deposited only externally on the hair fibers and / or the skin surface. Therefore, they can usually be removed without residue after several washes with surfactant-containing cleansers. Various products of this type are available on the market under the name hair mascara.

[0006] If the user desires particularly long-lasting color results, the use of oxidative colorants has so far been the only option. However, despite numerous optimization attempts, an unpleasant ammonia or amine odor cannot be completely avoided with oxidative hair coloring. The hair damage still associated with the use of oxidative colorants also has a detrimental effect on the user's hair. Therefore, the search for alternative, high-performance coloring methods remains a challenge. For this reason, pigment-based colorants are very popular. However, the color intensity and fastness properties of pigment-based colorants, in particular, still require significant improvement.

[0007] Mintel GNPD Record ID 7997249, "Gloss Semi-Permanent Treatment Gloss," August 2020, and Mintel GNPD Record ID 6691599, "Shade Shot Gloss," July 2019, both disclose an agent for coloring keratinous material, in particular human hair, containing (a1) at least one amino-functionalized silicone polymer (Bis-Cetearyl Amodimethicone), (a2) at least one color-imparting compound (Basic Red 51, Basic Brown 17, HC Blue No. 15), and (a3) ​​at least one addition product of C1-C6 alkylene oxide(s) with the esters of C12-C30 fatty acids and C1-C12 aromatic alcohols (PPG-3 Benzyl Ether Myristate). The agent is applied to the hair, left on for between 10 and 20 minutes, and then rinsed out.

[0008] The object of the present invention was to provide a colorant that makes it possible to fix pigments to the hair in an extremely permanent manner. When used in a coloring process, particularly intensive coloring results should be achieved. Furthermore, colorations with good washfastness, good leveling power, and a particularly uniform color result should be achieved. In addition, the abrasion of these pigment colorants should be particularly low, i.e., even upon mechanical contact with clothing or other textiles, the colorants should have particularly good rubfastness. Furthermore, the keratin material, in particular the hair, should feel neither weighed down nor dull or greasy after application of the pigment colorants and should have the most pleasant feel possible.Surprisingly, it has now been found that the above-mentioned object can be excellently achieved if keratinic materials, in particular hair, are dyed with an agent which contains at least one amino-functionalized silicone polymer (a1), at least one color-imparting compound (a2), and at least one addition product of C 1 -C 6 alkylene oxide(s) onto the esters of C 12 -C 30 fatty acids and aromatic C 1 -C 12 alcohols (a3).

[0009] A first subject of the present invention is an agent for coloring keratinic material, in particular human hair, containing (a1) at least one amino-functionalized silicone polymer, and (a2) at least one color-providing compound, (a3) ​​at least one addition product of C 1 -C 6 alkylene oxide(s) onto the esters of C 12 -C 30 fatty acids and aromatic C 1 -C 12 alcohols, and (a4) at least one addition product of C 1 -C 6 alkylene oxide(s) onto aliphatic C 1 -C 24 alkanols of the formula (AA-I).

[0010] In the course of the work leading to this invention, it was surprisingly found that the use of alkoxylated compounds (a3) ​​and (a4) in a composition containing an aminosilicone (a1) and a colorant (a2) leads to an improvement in color intensity and washfastness when this composition is applied in a coloring process to keratinous material, particularly human hair. These positive effects were observed particularly when the colorant (a2) is a pigment. keratin material

[0011] Keratinous material includes hair, skin, and nails (such as fingernails and / or toenails). Wool, fur, and feathers also fall under the definition of keratinous material.

[0012] Keratin material is preferably understood to mean human hair, human skin, and human nails, especially fingernails and toenails. Keratin material is most preferably understood to mean human hair. Coloring agents

[0013] In the context of this invention, the term "coloring agent" refers to the coloring of keratin material, especially hair, achieved through the use of coloring compounds, particularly pigments. During this coloring, the pigments, as coloring compounds, are deposited on the surface of the keratin material in a particularly homogeneous, uniform, and smooth film.

[0014] The agent according to the invention contains the components (a1), (a2), (a3) ​​and (a4) essential to the invention, preferably in a cosmetic carrier. amino-functionalized silicone polymers (a1)

[0015] As the first ingredient (a1) essential to the invention, the product contains at least one amino-functionalized silicone polymer. The amino-functionalized silicone polymer can alternatively be referred to as aminosilicone or amodimethicone.

[0016] Silicone polymers are generally macromolecules having a molecular weight of at least 500 g / mol, preferably at least 1000 g / mol, more preferably at least 2500 g / mol, particularly preferably at least 5000 g / mol, which comprise repeating organic units.

[0017] The maximum molecular weight of the silicone polymer depends on the degree of polymerization (number of polymerized monomers) and the batch size, and is also determined by the polymerization method. For the purposes of the present invention, it is preferred if the maximum molecular weight of the silicone polymer is no more than 10 7 g / mol, preferably no more than 10 6 g / mol, and particularly preferably no more than 10 5 g / mol.

[0018] Silicone polymers comprise numerous Si-O repeating units, where the Si atoms may carry organic residues such as alkyl or substituted alkyl groups. A silicone polymer is therefore also referred to as polydimethylsiloxane.

[0019] In accordance with the high molecular weight of the silicone polymers, these are based on more than 10 Si-O repeating units, preferably more than 50 Si-O repeating units and particularly preferably more than 100 Si-O repeating units, most preferably more than 500 Si-O repeating units.

[0020] An amino-functionalized silicone polymer is a functionalized silicone that carries at least one structural unit with an amino group. The amino-functionalized silicone polymer preferably carries multiple structural units, each with at least one amino group. An amino group is defined as a primary amino group, a secondary amino group, and a tertiary amino group. All of these amino groups can be protonated in an acidic environment and are then present in their cationic form.

[0021] In principle, good results could be achieved with amino-functionalized silicone polymers (a1) if they contain at least one primary, at least one secondary, and / or at least one tertiary amino group. However, dyeings with the best washfastness were observed when an amino-functionalized silicone polymer (a1) containing at least one secondary amino group was used in the product.

[0022] In a particularly preferred embodiment, an agent according to the invention is characterized in that it contains at least one amino-functionalized silicone polymer (a1) with at least one secondary amino group.

[0023] The secondary amino group(s) can be located at various positions on the amino-functionalized silicone polymer. Particularly good results were found when using an amino-functionalized silicone polymer (a1) that has at least one, preferably several, structural units of the formula (Si-amino).

[0024] In the structural units of the formula (Si-Amino), the abbreviations ALK1 and ALK2 independently represent a linear or branched, divalent C 1 -C 20 alkylene group.

[0025] In a further particularly preferred embodiment, an agent according to the invention is characterized in that it contains at least one amino-functionalized silicone polymer (a1) which comprises at least one structural unit of the formula (Si-Amino), where ALK1 and ALK2 independently represent a linear or branched, divalent C 1 -C 20 alkylene group.

[0026] The positions marked with an asterisk (*) indicate the bond to other structural units of the silicone polymer. For example, the silicon atom adjacent to the star can be bonded to another oxygen atom, and the oxygen atom adjacent to the star can be bonded to another silicon atom or to a C 1 -C 6 alkyl group.

[0027] A divalent C 1 -C 20 alkylene group can alternatively be referred to as a divalent or divalent C 1 -C 20 alkylene group, which means that each group ALK1 or AK2 can form two bonds.

[0028] In the case of ALK1, one bond is formed from the silicon atom to the ALK1 group, and the second bond is formed between ALK1 and the secondary amino group.

[0029] In the case of ALK2, one bond is formed from the secondary amino group to the ALK2 moiety, and the second bond is formed between ALK2 and the primary amino group.

[0030] Examples of a linear divalent C 1 -C 20 alkylene group are, for example, the methylene group (-CH 2 -), the ethylene group (-CH 2 -CH 2 -), the propylene group (-CH 2 -CH 2 -CH 2 -) and the butylene group (-CH 2 -CH 2 -CH 2 -CH 2 -). The propylene group (-CH 2 -CH 2 -CH 2 -) is particularly preferred. From a chain length of 3 C atoms, divalent alkylene groups can also be branched. Examples of branched, divalent C 3 -C 20 alkylene groups are (-CH 2 -CH(CH 3 )-) and (-CH 2 -CH(CH 3 )-CH 2 -).

[0031] In a further particularly preferred embodiment, the structural units of the formula (Si-amino) represent repeating units in the amino-functionalized silicone polymer (a1), so that the silicone polymer comprises several structural units of the formula (Si-amino).

[0032] Particularly suitable amino-functionalized silicone polymers (a1) with at least one secondary amino group are listed below.

[0033] Colorations with the very best wash fastnesses could be obtained when, in the process according to the invention, at least one agent was applied to the keratinic material which contains at least one amino-functionalized silicone polymer (a1) comprising structural units of the formula (Si-I) and the formula (Si-II)

[0034] In a further explicitly very particularly preferred embodiment, an agent according to the invention is characterized in that it contains at least one amino-functionalized silicone polymer (a1) which comprises structural units of the formula (Si-I) and the formula (Si-II)

[0035] An example of a corresponding amino-functionalized silicone polymer with the structural units (Si-I) and (Si-II) is the commercial product DC 2-8566 or Dowsil 2-8566 Amino Fluid, which is marketed by the Dow Chemical Company and is named "Siloxanes and Silicones, 3-[(2-Aminoethyl)amino]-2-methylpropyl Me, Di-Me-Siloxane" and has the CAS number 106842-44-8. Another amino-functionalized silicone polymer with the structural units (Si-I) and (Si-II) is the commercial product DOWSIL™ AP-8568 Amino Fluid, which is also marketed by the Dow Chemical Company.

[0036] In a further preferred embodiment, an agent according to the invention is characterized in that it contains at least one amino-functional silicone polymer (a1) of the formula (Si-III), where m and n are numbers chosen so that the sum (n + m) is in the range from 1 to 1000, n is a number in the range from 0 to 999 and m is a number in the range from 1 to 1000, R1, R2 and R3, which are the same or different, are a hydroxy group or a C1-4 alkoxy group, where at least one of the groups R1 to R3 is a hydroxy group;

[0038] The silicones of formulas (Si-III) and (Si-IV) differ in the grouping at the Si atom carrying the nitrogen-containing group: In formula (Si-III), R2 represents a hydroxyl group or a C1-4 alkoxy group, while the residue in formula (Si-IV) is a methyl group. The individual Si groups, which are designated by the indices m and n or p and q, do not have to be present as blocks; rather, the individual units can also be statistically distributed, i.e., in formulas (Si-III) and (Si-IV), not every R1-Si(CH3)2 group is necessarily bonded to an -[O-Si(CH3)2]- group.

[0048] These amino-functionalized silicone polymers are called amodimethicones according to the INCI declaration.

[0049] Regardless of which amino-functional silicones are used, agents according to the invention are preferred that contain an amino-functional silicone polymer whose amine number is above 0.25 meq / g, preferably above 0.3 meq / g, and in particular above 0.4 meq / g. The amine number represents the milliequivalents of amine per gram of the amino-functional silicone. It can be determined by titration and can also be expressed in mg KOH / g.

[0050] Furthermore, agents containing a special 4-morpholinomethyl-substituted silicone polymer (a1) are also suitable. This amino-functionalized silicone polymer comprises structural units of the formulas (SI-VIII) and (Si-IX). Corresponding 4-morpholinomethyl-substituted silicone polymers are described below.

[0051] A particularly preferred amino-functionalized silicone polymer is known as amodimethicone / morpholinomethyl silsesquioxane copolymer and is commercially available in the form of the raw material Belsil ADM 8301 E from Wacker.

[0052] For example, a silicone containing structural units of the formulas (Si-VIII), (Si-IX) and (Si-X) can be used as a 4-morpholinomethyl-substituted silicone. in which R1 stands for -CH 3 , -OH, -OCH 3 , -O-CH 2 CH 3 , -O-CH 2 CH 2 CH 3 , or -O-CH(CH 3 ) 2; R2 stands for -CH 3 , -OH, or -OCH 3.

B stands for a group -OH, -O-Si(CH 3 ) 3 ,-O-Si(CH 3 ) 2 OH,-O-Si(CH 3 ) 2 OCH 3, D stands for a group -H, -Si(CH 3 ) 3 ,-Si(CH 3 ) 2 OH, -Si(CH 3 ) 2 OCH 3, a, b and c independently of one another stand for integers between 0 and 1000, with the proviso that a + b + c > 0 m and n independently of one another stand for integers between 1 and 1000 with the proviso that at least one of the conditions B = -OH or D = -H is met, the units a, b, c, m and n are distributed statistically or in blocks in the molecule.

[0054] Structural formula (Si-XI) is intended to clarify that the siloxane groups n and m do not necessarily have to be directly bonded to an end grouping B or D. Rather, in preferred formulas (Si-VI), a > 0 or b > 0, and in particularly preferred formulas (Si-VI), a > 0 and c > 0, i.e., the terminal grouping B or D is preferably bonded to a dimethylsiloxy grouping. In formula (Si-VI), the siloxane units a, b, c, m, and n are also preferably distributed randomly.

[0055] The silicones used according to the invention and represented by formula (Si-VI) can be trimethylsilyl-terminated (D or B = -Si(CH 3 ) 3 ), but they can also be dimethylsilylhydroxy-terminated on two sides or dimethylsilylhydroxy- and dimethylsilylmethoxy-terminated on one side. Silicones particularly preferably used in the context of the present invention are selected from silicones in which B = -O-Si(CH 3 ) 2 OH and D = -Si(CH 3 ) 3 B = -O-Si(CH 3 ) 2 OH and D = -Si(CH 3 ) 2 OH B = -O-Si(CH 3 ) 2 OH and D = -Si(CH 3 ) 2 OCH 3 B = -O-Si(CH 3 ) 3 and D = -Si(CH 3 ) 2 OH B = -O-Si(CH 3 ) 2 OCH 3 and D = -Si(CH 3 ) 2 OH These silicones lead to exorbitant improvements in the properties of hair treated with the inventive agents, and to significantly improved protection during oxidative treatment.

[0056] It has proven particularly advantageous if the agent according to the invention contains the amino-functionalized silicone polymer(s) (a1) in specific amount ranges. Particularly good results were obtained when the agent contains—based on the total weight of the agent—a total amount of 0.1 to 8.0 wt.%, preferably 0.2 to 5.0 wt.%, more preferably 0.3 to 3.0 wt.%, and most preferably 0.4 to 2.5 wt.%.

[0057] In a further particularly preferred embodiment, an agent according to the invention is characterized in that it contains - based on the total weight of the agent - one or more amino-functionalized silicone polymers (a1) in a total amount of 0.1 to 8.0% by weight, preferably 0.2 to 5.0% by weight, more preferably 0.3 to 3.0% by weight and most preferably 0.4 to 2.5% by weight. color-giving compounds (a2)

[0058] As a second essential component, the agent according to the invention contains at least one color-providing compound (a2).

[0060] In a further preferred embodiment, an agent according to the invention is characterized in that it contains at least one color-providing compound (a2) from the group of pigments, direct dyes, photochromic dyes and thermochromic dyes.

[0061] Pigments in the sense of the present invention are understood to be color-imparting compounds which have a solubility in water at 25°C of less than 0.5 g / L, preferably less than 0.1 g / L, even more preferably less than 0.05 g / L. The water solubility can be determined, for example, using the method described below: 0.5 g of the pigment is weighed into a beaker. A stirring bar is added. Then, one liter of distilled water is added. This mixture is heated to 25°C for one hour while stirring on a magnetic stirrer. If undissolved components of the pigment are still visible in the mixture after this period, the solubility of the pigment is below 0.5 g / L. If the pigment-water mixture cannot be visually assessed due to the high intensity of the pigment, which may be present in finely dispersed form, the mixture is filtered.If a portion of undissolved pigment remains on the filter paper, the solubility of the pigment is below 0.5 g / L.

[0062] Suitable color pigments can be of inorganic and / or organic origin.

[0063] In a preferred embodiment, an agent according to the invention is characterized in that it contains at least one color-providing compound (a2) from the group of inorganic and / or organic pigments.

[0064] Preferred color pigments are selected from synthetic or natural inorganic pigments. Inorganic color pigments of natural origin can be made from chalk, ochre, umber, green earth, burnt sienna, or graphite, for example.

Particularly preferred pearlescent pigments are based on natural or synthetic mica and coated with one or more of the aforementioned metal oxides. The color of the respective pigments can be varied by varying the layer thickness of the metal oxide(s).

[0074] In a further embodiment, the agent according to the invention may also contain one or more coloring compounds (a2) from the group of organic pigments

[0075] The organic pigments according to the invention are correspondingly insoluble, organic dyes or lakes which can be selected, for example, from the group of nitroso, nitro, azo, xanthene, anthraquinone, isoindolinone, isoindoline, quinacridone, perinone, perylene, diketopyrrolopyorrole, indigo, thioindido, dioxazine and / or triarylmethane compounds.

[0076] Particularly suitable organic pigments are, for example, carmine, quinacridone, phthalocyanine, sorghum, blue pigments with the color index numbers CI 42090, CI 69800, CI 69825, CI 73000, CI 74100, CI 74160, yellow pigments with the color index numbers CI 11680, CI 11710, CI 15985, CI 19140, CI 20040, CI 21100, CI 21108, CI 47000, CI 47005, green pigments with the color index numbers CI 61565, CI 61570, CI 74260, orange pigments with the color index numbers CI 11725, CI 15510, CI 45370, CI 71105, red pigments with the Color Index Numbers CI 12085, CI 12120, CI 12370, CI 12420, CI 12490, CI 14700, CI 15525, CI 15580, CI 15620, CI 15630, CI 15800, CI 15850, CI 15865, CI 15880, CI 17200, CI 26100, CI 45380, CI 45410, CI 58000, CI 73360, CI 73915 and / or CI 75470.

[0077] In a further particularly preferred embodiment, a composition according to the invention is characterized in that it contains at least one color-providing compound (a2) from the group of organic pigments, which is preferably selected from the group of carmine, quinacridone, phthalocyanine, sorghum, blue pigments with the color index numbers CI 42090, CI 69800, CI 69825, CI 73000, CI 74100, CI 74160, yellow pigments with the color index numbers CI 11680, CI 11710, CI 15985, CI 19140, CI 20040, CI 21100, CI 21108, CI 47000, CI 47005, green pigments with the color index numbers CI 61565, CI 61570, CI 74260, orange pigments with the color index numbers CI 11725, CI 15510, CI 45370, CI 71105, red pigments with the color index numbers CI 12085, CI 12120, CI 12370, CI 12420, CI 12490, CI 14700, CI 15525, CI 15580, CI 15620, CI 15630, CI 15800, CI 15850, CI 15865, CI 15880, CI 17200, CI 26100, CI 45380, CI 45410, CI 58000, CI 73360, CI 73915 and / or CI 75470.

[0078] The organic pigment can also be a colored lake. For the purposes of the invention, the term colored lake refers to particles comprising a layer of absorbed dyes, the particle-dye unit being insoluble under the aforementioned conditions. The particles can be, for example, inorganic substrates, which can be aluminum, silica, calcium borosilicate, calcium aluminum borosilicate, or even aluminum.

[0079] Alizarin lake, for example, can be used as a colored varnish.

[0080] Due to their excellent light and temperature stability, the use of the aforementioned pigments in the composition is particularly preferred. Furthermore, it is preferred if the pigments used have a specific particle size. It is therefore advantageous according to the invention if the at least one pigment has an average particle size D 50 of 1.0 to 50 µm, preferably of 5.0 to 45 µm, preferably of 10 to 40 µm, in particular of 14 to 30 µm. The average particle size D 50 can be determined, for example, using dynamic light scattering (DLS).

[0081] The coloring compounds (a2), in particular the coloring compounds from the group of pigments, represent the second essential component of the composition according to the invention and are preferably used in the composition in specific amounts. Particularly good results were obtained when the composition contained one or more pigments (a2) in a total amount of 0.01 to 10.0 wt. %, preferably 0.1 to 5.0 wt. %, more preferably 0.2 to 2.5 wt. %, and most preferably 0.25 to 1.5 wt. %, based on the total weight of the composition.

[0082] In a further very particularly preferred embodiment, an agent according to the invention is characterized in that the agent - based on the total weight of the agent - contains one or more pigments (a2) in a total amount of 0.01 to 10.0 wt.%, preferably 0.1 to 5.0 wt.%, more preferably 0.2 to 2.5 wt.% and very particularly preferably 0.25 to 1.5 wt.%.

[0083] The compositions according to the invention can also contain one or more direct dyes as color-providing compounds (a2). Direct dyes are dyes that are absorbed directly onto the hair and do not require an oxidative process to develop the color. Direct dyes are typically nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinones, triarylmethane dyes, or indophenols.

[0084] The direct dyes according to the present invention have a solubility in water (760 mmHg) at 25°C of more than 0.5 g / L and are therefore not considered pigments. Preferably, the direct dyes according to the present invention have a solubility in water (760 mmHg) at 25°C of more than 1.0 g / L.

[0085] Direct dyes can be divided into anionic, cationic and non-ionic direct dyes.

[0086] In a further embodiment, a process according to the invention is characterized in that the agent contains at least one color-providing compound (a2) from the group of anionic, non-ionic and cationic direct dyes.

[0087] Suitable cationic direct dyes are, for example, Basic Blue 7, Basic Blue 26, HC Blue 16, Basic Violet 2 and Basic Violet 14, Basic Yellow 57, Basic Red 76, Basic Blue 16, Basic Blue 347 (Cationic Blue 347 / Dystar), HC Blue No. 16, Basic Blue 99, Basic Brown 16, Basic Brown 17, Basic Yellow 57, Basic Yellow 87, Basic Orange 31, Basic Red 51 Basic Red 76.

[0088] Non-ionic substantive dyes that can be used include non-ionic nitro and quinone dyes and neutral azo dyes. Suitable non-ionic substantive dyes are those known under the international designations "Substantive Dyes" and "Substantive Dyes" respectively.Handelsnamen HC Yellow 2, HC Yellow 4, HC Yellow 5, HC Yellow 6, HC Yellow 12, HC Orange 1, Disperse Orange 3, HC Red 1, HC Red 3, HC Red 10, HC Red 11, HC Red 13, HC Red BN, HC Blue 2, HC Blue 11, HC Blue 12, Disperse Blue 3, HC Violet 1, Disperse Violet 1, Disperse Violet 4, Disperse Black 9 bekannten Verbindungen, sowie 1,4-Diamino-2-nitrobenzol, 2-Amino-4-nitrophenol, 1,4-Bis-(2-hydroxyethyl)-amino-2-nitrobenzol, 3-Nitro-4-(2-hydroxyethyl)-aminophenol, 2-(2-Hydroxyethyl)amino-4,6-dinitrophenol, 4-[(2-Hydroxyethyl)amino]-3-nitro-1-methylbenzol, 1-Amino-4-(2-hydroxyethyl)-amino-5-chlor-2-nitrobenzol, 4-Amino-3-nitrophenol, 1-(2'-Ureidoethyl)amino-4-nitrobenzol, 2-[(4-Amino-2-nitrophenyl)amino]-benzoesäure, 6-Nitro-1,2,3,4-tetrahydrochinoxalin, 2-Hydroxy-1,4-naphthochinon, Pikraminsäure und deren Salze, 2-Amino-6-chloro-4-nitrophenol, 4-Ethylamino-3-nitrobenzoesäure und 2-Chlor-6-ethylamino-4-nitrophenol.

[0089] Anionic substantive dyes are also known as acid dyes. Acid dyes are understood to be substantive dyes that contain at least one carboxylic acid group (-COOH) and / or one sulfonic acid group (-SO 3 H). Depending on the pH, the protonated forms (-COOH, -SO 3 H) of the carboxylic acid or sulfonic acid groups are in equilibrium with their deprotonated forms (-COO -< , -SO 3 -< before). As the pH decreases, the proportion of protonated forms increases. If substantive dyes are used in the form of their salts, the carboxylic acid groups or sulfonic acid groups are in deprotonated form and are neutralized with corresponding stoichiometric equivalents of cations to maintain electroneutrality. Acid dyes according to the invention can also be used in the form of their sodium salts and / or their potassium salts.

[0090] The acid dyes according to the present invention have a solubility in water (760 mmHg) at 25°C of more than 0.5 g / L and are therefore not considered pigments. Preferably, the acid dyes according to the present invention have a solubility in water (760 mmHg) at 25°C of more than 1.0 g / L.

[0091] The alkaline earth metal salts (such as calcium and magnesium salts) and aluminum salts of acid dyes often have lower solubility than the corresponding alkali metal salts. If the solubility of these salts is below 0.5 g / L (25 °C, 760 mmHg), they do not fall under the definition of a direct dye.

[0092] A key feature of acid dyes is their ability to form anionic charges, with the carboxylic acid or sulfonic acid groups responsible for this being typically linked to various chromophoric systems. Suitable chromophoric systems can be found, for example, in the structures of nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinone dyes, triarylmethane dyes, xanthene dyes, rhodamine dyes, oxazine dyes, and / or indophenol dyes.

[0093] In a further embodiment, a method for dyeing keratinic material is characterized in that the agent contains at least one anionic direct dye selected from the group of nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinone dyes, triarylmethane dyes, xanthene dyes, rhodamine dyes, oxazine dyes and / or indophenol dyes, wherein the dyes from the aforementioned group each have at least one carboxylic acid group (-COOH), a sodium carboxylate group (-COONa), a potassium carboxylate group (-COOK), a sulfonic acid group (-SO 3 H), a sodium sulfonate group (-SO 3 Na) and / or a potassium sulfonate group (-SO 3 K).

[0094] Suitable acid dyes can be, for example, one or more compounds selected from the following group: Acid Yellow 1 (D&C Yellow 7, Citronin A, Ext.

[0095] The water solubility of anionic direct dyes can be determined, for example, as follows: 0.1 g of the anionic direct dye is placed in a beaker. A stir bar is attached. Then, 100 ml of water is added. This mixture is heated to 25 °C on a magnetic stirrer while stirring. It is stirred for 60 minutes. The aqueous mixture is then visually assessed. If undissolved residues remain, the amount of water is increased—for example, in 10 ml increments. Water is added until the used amount of dye has completely dissolved. If the dye-water mixture cannot be assessed visually due to the high intensity of the dye, the mixture is filtered. If a portion of undissolved dye remains on the filter paper, the solubility test is repeated using a larger amount of water.If 0.1 g of the anionic direct dye dissolves in 100 ml of water at 25 °C, the solubility of the dye is 1.0 g / L.

[0096] Acid Yellow 1 is called 8-hydroxy-5,7-dinitro-2-naphthalenesulfonic acid disodium salt and has a solubility in water of at least 40 g / L (25°C).

[0097] Acid Yellow 3 is a mixture of the sodium salts of mono- and sulfonic acids of 2-(2-quinolyl)-1H-indene-1,3(2H)-dione and has a water solubility of 20 g / L (25 °C).

[0098] Acid Yellow 9 is the disodium salt of 8-hydroxy-5,7-dinitro-2-naphthalenesulfonic acid, its water solubility is above 40 g / L (25 °C).

[0099] Acid Yellow 23 is the trisodium salt of 4,5-dihydro-5-oxo-1-(4-sulfophenyl)-4-((4-sulfophenyl)azo)-1H-pyrazole-3-carboxylic acid and is readily soluble in water at 25 °C.

[0100] Acid Orange 7 is the sodium salt of 4-[(2-hydroxy-1-naphthyl)azo]benzenesulfonate. Its water solubility is greater than 7 g / L (25 °C).

[0101] Acid Red 18 is the trisodium salt of 7-hydroxy-8-[(E)-(4-sulfonato-1-naphthyl)-diazenyl]-1,3-naphthalenedisulfonate and has a very high water solubility of more than 20 wt%. Acid Red 33 is the dibasic salt of 5-amino-4-hydroxy-3-(phenylazo)-naphthalene-2,7-disulfonate; its water solubility is 2.5 g / L (25 °C).

[0104] In einer weiteren Ausführungsform ist ein erfindungsgemäßes Mittel daher dadurch gekennzeichnet, dass es mindestens einen direktziehenden Farbstoff (a2) enthält, der ausgewählt ist aus der Gruppe aus Acid Yellow 1, Acid Yellow 3, Acid Yellow 9, Acid Yellow 17, Acid Yellow 23, Acid Yellow 36, Acid Yellow 121, Acid Orange 6, Acid Orange 7, Acid Orange 10, Acid Orange 11, Acid Orange 15, Acid Orange 20, Acid Orange 24, Acid Red 14, Acid Red, Acid Red 27, Acid Red 33, Acid Red 35, Acid Red 51, Acid Red 52, Acid Red 73, Acid Red 87, Acid Red 92, Acid Red 95, Acid Red 184, Acid Red 195, Acid Violet 43, Acid Violet 49, Acid Violet 50, Acid Blue 1, Acid Blue 3, Acid Blue 7, Acid Blue 104, Acid Blue 9, Acid Blue 62, Acid Blue 74, Acid Blue 80, Acid Green 3, Acid Green 5, Acid Green 9, Acid Green 22, Acid Green 25, Acid Green 50, Acid Black 1, Acid Black 52, Food Yellow 8, Food Blue 5, D&C Yellow 8, D&C Green 5, D&C Orange 10, D&C Orange 11, D&C Red 21, D&C Red 27, D&C Red 33,D&C Violet 2 and / or D&C Brown 1.,

[0105] The direct dye(s) can be used in the product in various amounts depending on the desired color intensity. Good results have been achieved when the product contains—based on the total weight of the product—one or more direct dyes (a2) in a total amount of 0.01 to 10.0 wt.%, preferably 0.1 to 8.0 wt.%, more preferably 0.2 to 6.0 wt.%, and most preferably 0.5 to 4.5 wt.%.

[0106] Furthermore, the agent may also contain at least one photochromic or thermochromic dye as coloring compound (a2).

[0107] Photochromic dyes are dyes that react to UV light (sunlight or black light) with a reversible color change. The UV light alters the chemical structure of the dyes and thus their absorption behavior (photochromism).

[0108] Thermochromic dyes are dyes that react to temperature changes with a reversible color change. The temperature change alters the chemical structure of the dyes and thus their absorption behavior (thermochromism).

[0109] The agent may contain - based on the total weight of the agent - one or more photochromic dyes (a2) in a total amount of 0.01 to 10.0 wt.%, preferably 0.1 to 8.0 wt.%, more preferably 0.2 to 6.0 wt.% and most preferably 0.5 to 4.5 wt.% Addition products of C 1 -C 6 alkylene oxide(s) to the esters of C 12 -C 30 fatty acids and aromatic C 1 -C 12 alcohols (a3)

[0110] As a third essential ingredient (a3), the agents according to the invention contain at least one addition product of C 1 -C 6 alkylene oxide(s) with the esters of C 12 -C 30 fatty acids and aromatic C 1 -C 12 alcohols.

[0111] The addition products of C 1 -C 6 alkylene oxide(s) to the esters of C 12 -C 30 fatty acids and aromatic C 1 -C 12 alcohols (a3) ​​are hereinafter also referred to as alkoxylated fatty acid esters (a3).

[0112] C 1 -C 6 alkylene oxides are the epoxides of C 1 -C 6 alkanes. Particularly suitable C 1 -C 6 alkylene oxides include ethylene oxide (1,2-epoxyethane), propylene oxide (1,2-epoxypropane), and butylene oxides (1,2-epoxybutane and 2,3-epoxybutane).

[0113] The ethoxylated fatty acid esters (a3) ​​are based on C 12 -C 30 fatty acids. These C 12 -C 30 fatty acids according to the invention are linear or branched, saturated or monounsaturated or polyunsaturated fatty acids, which may also carry one or more hydroxyl groups. The C 12 -C 24 fatty acids according to the invention are characterized in that they comprise 12 to 30 carbon atoms, preferably 12 to 24 carbon atoms. Furthermore, the C 12 -C 24 fatty acids carry at least one carboxylic acid moiety.

[0114] To form the ethoxylated fatty acid esters (a3) ​​according to the invention, one or more fatty acids can be used, for example, which are selected from the group consisting of dodecanoic acid (lauric acid), tetradecanoic acid (myristic acid), hexadecanoic acid (palmitic acid), tetracosanoic acid (lignoceric acid), octadecanoic acid (stearic acid), eicosanoic acid (arachidic acid), docosanoic acid (behenic acid), petroselinic acid [(Z)-6-octadecenoic acid], palmitoleic acid [(9Z)-hexadec-9-enoic acid], oleic acid [(9Z)-octadec-9-enoic acid], elaidic acid [(9E)-octadec-9-enoic acid], erucic acid [(13Z)-docos-13-enoic acid], linoleic acid [(9Z, 12Z)-octadeca-9,12-dienoic acid, linolenic acid [(9Z,12Z,15Z)-octadeca-9,12,15-trienoic acid, elaostearic acid [(9Z,11E,13E)-octadeca-9,11,3-trienoic acid], arachidonic acid [(5Z,8Z,11Z,14Z)-icosa-5,8,11,14-tetraenoic acid], nervonic acid [(15Z)-tetracos-15-enoic acid] and / or ricinoleic acid ((9Z,12R)-12-hydroxy-9-octadecenoic acid).

[0115] The ethoxylated fatty acid esters (a3) ​​are addition products of C 1 -C 6 alkylene oxide(s) with the esters of the previously described C 12 -C 24 fatty acids and aromatic C 1 -C 12 alcohols. A characteristic of the aromatic C 1 -C 12 alcohols is that they comprise 1 to 12 carbon atoms and at least one aromatic ring system. The aromatic C 1 -C 12 alcohols each have at least one hydroxy group, which can either be located directly on the aromatic ring (as in the case of phenol) or can be linked to the aromatic ring via an aliphatic unit (as in the case of benzyl alcohol or 2-phenoxyethanol). The structures of the aromatic C 1 -C 12 alcohols can also comprise further heteroatoms such as oxygen or nitrogen.

[0116] The corresponding aromatic C 1 -C 12 alcohols can be mono- or polyhydric alcohols, ie the alcohols can have one or more hydroxy groups.

[0117] Monohydric aromatic C 1 -C 12 alcohols are particularly preferred. This class of compounds contains exactly one hydroxy group. Suitable examples include phenol, benzyl alcohol, 2-phenylethyl alcohol, and 2-phenoxyethanol.

[0118] Particularly preferred is therefore an agent for coloring keratinic material, in particular human hair, containing (a1) at least one amino-functionalized silicone polymer, and (a2) at least one color-providing compound, (a3) ​​at least one addition product of C 1 -C 6 alkylene oxide(s) with the esters of C 12 -C 30 fatty acids and monohydric aromatic C 1 -C 12 alcohols, and (a4) at least one addition product of C1 -C6 alkylene oxide(s) with aliphatic C1-C24 alkanols of the formula (AA-I).

[0119] Particularly good wash fastness and rub fastness properties could be obtained when at least one addition product (a3) ​​of C 1 -C 6 alkylene oxide(s) with an ester obtained by esterification of a C 12 -C 30 fatty acid with an aromatic C 1 -C 12 alcohol from the group consisting of benzyl alcohol, phenol, 2-phenylethyl alcohol and 2-phenoxyethanol was used in the agent according to the invention.

[0120] In a further preferred embodiment, an agent according to the invention is characterized in that it contains (a3) ​​at least one addition product of C 1 -C 6 alkylene oxide(s) with an ester which is obtained by esterification of a C 12 -C 24 fatty acid with an aromatic C 1 -C 12 alcohol from the group consisting of benzyl alcohol, phenol, 2-phenylethyl alcohol and 2-phenoxyethanol, very particularly preferably benzyl alcohol.

[0121] In a particularly preferred embodiment, an agent according to the invention is characterized in that it contains (a3) ​​at least one addition product of C 1 -C 6 alkylene oxide(s) with an ester obtained by esterification of a C 12 -C 24 fatty acid with benzyl alcohol.

[0122] In a further preferred embodiment, an agent according to the invention is characterized in that it contains (a3) ​​at least one addition product of ethylene oxide and / or propylene oxide with an ester which is obtained by esterification of a C 12 -C 24 fatty acid with an aromatic C 1 -C 12 alcohol from the group consisting of benzyl alcohol, phenol, 2-phenylethyl alcohol and 2-phenoxyethanol.

[0123] In a further particularly preferred embodiment, an agent according to the invention is characterized in that it contains (a3) ​​at least one addition product of ethylene oxide and / or propylene oxide with an ester which is obtained by esterification of a C 12 -C 24 fatty acid with benzyl alcohol.

[0124] As already described above, particularly suitable C 1 -C 6 alkylene oxides include, for example, ethylene oxide (1,2-epoxyethane), propylene oxide (1,2-epoxypropane), and butylene oxides (1,2-epoxybutane and 2,3-epoxybutane). Ethylene oxide (1,2-epoxyethane) and propylene oxide (1,2-epoxypropane) are explicitly particularly preferred. Propylene oxide (1,2-epoxypropane) is most preferred.

[0125] A corresponding addition product of ethylene oxide to the esters of C 12 -C 30 fatty acids and aromatic C 1 -C 12 alcohols (a3) ​​is formed when the C 12 -C 30 fatty acid itself or the ester already formed from it is reacted with ethylene oxide (alternatively 1,2-epoxyethane, CAS number 75-21-8).

[0126] Analogously, a corresponding addition product of propylene oxide to the esters of C 12 -C 30 fatty acids and aromatic C 1 -C 12 alcohols (a3) ​​is formed when the C 12 -C 30 fatty acid itself or the ester already formed from it is reacted with propylene oxide (alternative name 1,2-epoxypropane, CAS numbers 75-56-9 (racemate), 15448-47-2 ((R)-enantiomer, 16088-62-3 (S)-enantiomer).

[0127] If the C 12 -C 30 fatty acid itself is reacted with ethylene oxide, an adduct can initially form starting from the carboxylic acid grouping of the C 12 -C 30 fatty acid and the ethylene oxide, so that a *-C(O)-O-CH 2 -CH 2 -O-* grouping is formed. This grouping is also an ester. If one mole of ethylene oxide is reacted per mole of fatty acid, on average a simple adduct with one *-CH 2 -CH 2 -O-* unit is formed. Depending on the molar excess in which ethylene oxide is used, however, multiple adducts can also form, with several *-CH 2 -CH 2 -O-* units being present per mole of C 12 -C 30 fatty acid. To form the ester (a3), this adduct is then further reacted with at least one aromatic C 1 -C 12 alcohol. The positions marked with an asterisk represent the bond to the remaining part of the fatty acid and the bond to the remaining part of the alcohol.

[0128] If the C 12 -C 30 fatty acid is reacted analogously with propylene oxide, an adduct can initially form starting from the carboxylic acid grouping of the C 12 -C 30 fatty acid and the propylene oxide, so that a grouping *-C(O)-O-CH(CH 3 )-CH 2 -O-* or a grouping *-C(O)-O-CH 2 -CH(CH 3 )-O-*. The reaction mixture usually contains a mixture of the two aforementioned groupings. Both groupings are also esters. If one mole of propylene oxide is reacted per mole of fatty acid, on average a simple adduct with a mixture of the units *-CH(CH 3 )-CH 2 -O-* and *-CH 2 -CH(CH 3 )-O-* is formed. However, depending on the molar excess of propylene oxide used, multiple adducts can also form, with several units of *-CH(CH 3 )-CH 2 -O-* and / or *-CH 2 -CH(CH 3 )-O-* being present per mole of C 12 -C 30 fatty acid.To form the ester (a3), this adduct is then further reacted with at least one aromatic C 1 -C 12 alcohol. The positions marked with an asterisk represent the bond to the remaining fatty acid and the bond to the remaining alcohol.

[0129] Furthermore, it is conceivable in principle that the C 12 -C 30 fatty acid could be reacted with a mixture of ethylene oxide and propylene oxide. In this case, mixtures of the previously described adducts are formed. Reactions of higher alkylene oxides, such as butylene oxide, with the C 12 -C 30 fatty acids are also possible in this way.

[0130] The addition products produced in this way lead, for example, to the alkoxylated fatty acid esters of the general formula (AFE-I) where R1 represents a saturated or unsaturated C 11 -C 29 alkyl group, R2, R3 independently represent a hydrogen atom, a C 1 -C 6 alkyl group, a hydroxy group or a C 1 -C 6 alkoxy group, n represents the number 0 or 1, m represents an integer from 0 to 6, o represents an integer from 1 to 60, and Q represents a structural unit -O-CH 2 -CH 2 -, -O-CH(CH 3 )-CH 2 - or -O-CH 2 -CH(CH 3 )-, where the proviso is that if m is 0, then n is also 0.

[0131] Dyes that were particularly distinguished with regard to good washfastness and rubfastness were obtained using dyeing agents containing at least one ethoxylated fatty acid ester (a3) ​​of the formula (AFE-I). For this reason, the use of one or more ethoxylated fatty acid esters (a3) ​​of the formula (AFE-I) in the dyeing agents according to the invention is particularly preferred.

[0132] In a further particularly preferred embodiment, an agent according to the invention is characterized in that it contains (a3) ​​at least one alkoxylated fatty acid ester of the general formula (AFE-I) where R1 represents a saturated or unsaturated C 11 -C 29 alkyl group, R2, R3 independently represent a hydrogen atom, a C 1 -C 6 alkyl group, a hydroxy group or a C 1 -C 6 alkoxy group, n represents the number 0 or 1, m Q represents an integer from 0 to 6, o represents an integer from 1 to 60, and represents a structural unit -O-CH 2 -CH 2 -, -O-CH(CH 3 )-CH 2 - or -O-CH 2 -CH(CH 3 )-, where the proviso is that if m is 0, then n is also 0.

[0133] The radical R1 represents a saturated or unsaturated C11-C29 alkyl group. An unsaturated C11-C23 alkyl group may contain one or more double bonds and is alternatively referred to as an unsaturated C11-C23 alkenyl group. The saturated or unsaturated C11-C29 alkyl group may be linear or branched.

[0134] Preferably, R1 represents a linear, saturated or unsaturated C11-C23 alkyl group.

[0135] The radicals R2 and R3 each represent a hydrogen atom, a C1-C6 alkyl group, a hydroxy group, or a C1-C6 alkoxy group. Most preferably, the radicals R2 and R3 both represent a hydrogen atom.

[0136] The index number n stands for the number 0 or 1. Preferably, n stands for the number 0.

[0137] The index number m stands for an integer from 0 to 6. Preferably, m stands for the number 1.

[0138] The index number o stands for an integer from 1 to 60. Preferably, o stands for an integer from 1 to 30, more preferably from 1 to 20, even more preferably from 1 to 10 and most preferably from 1 to 5.

[0139] The radical Q represents a structural unit -O-CH 2 -CH 2 -, -O-CH(CH 3 )-CH 2 - or -O-CH 2 -CH(CH 3 )-. Q particularly preferably represents a structural unit -O-CH(CH 3 )-CH 2 - or -O-CH 2 -CH(CH 3 )-.

[0140] If o stands for a number greater than 1, the compounds of formula (AFE-I) (or also formula (AFE-II)) contain several structural units Q; in this case, each structural unit Q can be chosen independently of the other structural units Q.

[0141] Accordingly, a preferred agent according to the invention is characterized in that it contains (a3) ​​at least one alkoxylated fatty acid ester of the general formula (AFE-I) where R1 represents a saturated or unsaturated C 11 -C 29 alkyl group, R2, R3 independently represent a hydrogen atom, a C 1 -C 6 alkyl group, a hydroxy group or a C 1 -C 6 alkoxy group, n represents the number 0 or 1, m represents an integer from 0 to 6, o represents an integer from 1 to 60, and Q represents a structural unit -O-CH 2 -CH 2 -, -O-CH(CH 3 )-CH 2 - or -O-CH 2 -CH(CH 3 )-, with the proviso that if m is 0, then n is also 0, and if o is greater than 1, each structural unit Q can be chosen independently of the other structural units Q.

[0142] In summary, particularly good results were obtained with the agents according to the invention which contained (a3) ​​at least one alkoxylated fatty acid ester of the general formula (AFE-I), where R1 represents a saturated or unsaturated C 11 -C 29 alkyl group, R2, R3 both represent a hydrogen atom, n represents the number 0, m represents the number 1, o represents an integer from 1 to 30, preferably from 1 to 20, more preferably from 1 to 10 and most preferably from 1 to 5, and Q represents a structural unit -O-CH(CH 3 )-CH 2 - or -O-CH 2 -CH(CH 3 )-.

[0143] In a further particularly preferred embodiment, an agent according to the invention is characterized in that it contains (a3) ​​at least one alkoxylated fatty acid ester of the general formula (AFE-I) where R1 represents a saturated or unsaturated C 11 -C 29 alkyl group, R2, R3 both represent a hydrogen atom, n represents the number 0, m represents the number 1, o represents an integer from 1 to 30, preferably from 1 to 20, more preferably from 1 to 10 and most preferably from 1 to 5, and Q represents a structural unit -O-CH(CH 3 )-CH 2 - or -O-CH 2 -CH(CH 3 )-.

[0144] The most preferred alkoxylated fatty acid esters of this embodiment also fall under the general formula (AFE-II) where R1 represents a saturated or unsaturated C 11 -C 29 alkyl group, or represents an integer from 1 to 30, preferably from 1 to 20, more preferably from 1 to 10 and most preferably from 1 to 5, and Q represents a structural unit -O-CH(CH 3 )-CH 2 - or -O-CH 2 -CH(CH 3 )-.

[0145] In a further particularly preferred embodiment, an agent according to the invention is characterized in that it contains (a3) ​​at least one alkoxylated fatty acid ester of the general formula (AFE-II) where R1 represents a saturated or unsaturated C 11 -C 29 alkyl group, or represents an integer from 1 to 30, preferably from 1 to 20, more preferably from 1 to 10 and most preferably from 1 to 5, and Q represents a structural unit -O-CH(CH 3 )-CH 2 - or -O-CH 2 -CH(CH 3 )-.

[0146] Again, in the case of o greater than 1, each structural unit Q can be chosen independently of the other structural units Q.

[0147] Here, the structural units Q are aligned in the alkoxylated fatty acid esters of the general formula (AFE-II) such that the oxygen atom in the grouping -O-CH(CH 3 )-CH 2 -or -O-CH 2 -CH(CH 3 )- is adjacent to the benzyl group, and the respective unit - CH2- or -CH(CH3)- is adjacent to the ester group -OC(O)-R1.

[0148] A particularly suitable compound of this type is PPG-3 Benzyl Ether Myristate, which is also alternatively known as α-(1-oxotetradecyl)-ω-(phenylmethoxy) poly[oxy(methyl-1,2-ethanediyl)] and has the CAS number 642443-86-5. PPG-3 Benzyl Ether Myristate can be purchased, for example, from Croda under the trade name Crodamol STS.

[0149] In a further particularly preferred embodiment, an agent according to the invention is characterized in that it contains (a3) ​​PPG-3 Benzyl Ether Myristate.

[0150] Another type of addition product of ethylene oxide to the esters of C 12 -C 30 fatty acids and aromatic C 1 -C 12 alcohols (a3) ​​occurs when an ester is reacted with a C 1 -C 6 alkylene oxide, this ester being obtained by esterification of a C 12 -C 30 fatty acid having at least one hydroxy group with an aromatic C 1 -C 12 alcohol. For example, ricinoleic acid ((9Z,12R)-12-hydroxy-9-octadecenoic acid) can first be esterified with benzyl alcohol, phenol, 2-phenylethyl alcohol, or 2-phenoxyethanol. Upon formation of these adducts, the C 1 -C 6 alkylene oxide(s) then add to the hydroxy group of the ricinoleic acid.

[0151] If one mole of C 1 -C 6 alkylene oxide is reacted per mole of fatty acid, then - if, for example, ethylene oxide is used as the alkylene oxide, one unit of *-CH 2 -CH 2 -O-* can add to the hydroxyl group of the castor oil acid. Depending on the molar excess in which the ethylene oxide is used, however, multiple adducts can also form, with several units of *-CH 2 -CH 2 -O-* being added to each hydroxyl group of the fatty acid, and / or with several units of *-CH 2 -CH 2 -O-* being added to each free hydroxyl group of the glycerol. These addition products of C 1 -C 6 alkylene oxide(s) with the esters of C 12 -C 30 fatty acids and aromatic C 1 -C 12 alcohols are also according to the invention.

[0152] The alkoxylated fatty acid esters (a3) ​​are particularly preferably used in certain amount ranges in the agent according to the invention.

[0153] Particularly good results were obtained when the agent - based on the total weight of the agent - contained one or more alkoxylated fatty acid esters (a3) ​​in a total amount of 0.1 to 20.0 wt.%, preferably 0.5 to 15.0 wt.%, more preferably from 1.0 to 10.0 wt.%, even more preferably from 1.0 to 6.0 wt.% and most preferably from 1.0 to 1.8 wt.%.

[0154] Within the scope of a further preferred embodiment, an agent according to the invention is characterized in that it contains - based on the total weight of the agent - one or more alkoxylated fatty acid esters (a3) ​​in a total amount of 0.1 to 20.0 wt.%, preferably 0.5 to 15.0 wt.%, more preferably from 1.0 to 10.0 wt.%, even more preferably from 1.0 to 6.0 wt.% and very particularly preferably from 1.0 to 1.8 wt.%.

[0155] In the work leading to this invention, it has been found that the presence of one or more of the previously described alkoxylated fatty acid esters (a3) ​​optimally disperses the coloring compounds (a2), particularly when these are pigments, in the composition according to the invention. It is assumed that the pigments, which are thus particularly finely dispersed in the composition, can be applied to the keratin material particularly evenly and in the form of a fine, resistant film, which results in particularly good rubfastness of the resulting colorations. Furthermore, it is assumed that this particularly fine dispersion of the pigments in the composition is also responsible for the good washfastness that can be achieved with the compositions according to the invention.

[0156] Thus, very good results were obtained when the alkoxylated fatty acid ester(s) (a3) ​​were included as the essential dispersing aid(s) or additive(s) in the composition according to the invention. Further studies have shown that this effect can be further enhanced by adding another C 1 -C 6 alkylene oxide addition product (a4) to the compositions. Addition products of C 1 -C 6 alkylene oxide(s) with aliphatic C 1 -C 24 alkanols (a4)

[0157] The substance group (a4), which is particularly effective as a further dispersing additive, is the addition products of C 1 -C 6 alkylene oxides with C1-C24 alkanols.

[0158] In the following, the addition products of C 1 -C 6 alkylene oxide(s) to aliphatic C 1 -C 24 alkanols (a4) are also referred to as alkoxylated alkanols.

[0159] The addition products of C 1 -C 6 alkylene oxide(s) to aliphatic C 1 -C 24 alkanols (a4) are the compounds of the general formula (AA-I) wherein R4 represents a saturated or unsaturated C 1 -C 12 alkyl group and P represents a structural unit -O-CH 2 -CH 2 -, -O-CH(CH 3 )-CH 2 - or -O-CH 2 -CH(CH 3 )-, and s represents an integer from 1 to 60.

[0160] The radical R4 represents a saturated or unsaturated C1-C12 alkyl group. R4 radicals can be unsaturated if they contain at least 2 carbon atoms. An unsaturated alkyl group can contain one or more double bonds and is alternatively referred to as a C2-C12 alkenyl group. The saturated or unsaturated C1-C12 alkyl group can be linear or branched.

[0161] Particularly preferably, the radical R4 represents a saturated, unbranched C1-C12 alkyl group. Most preferably, the radical R4 represents a saturated, unbranched C1-C6 alkyl group.

[0162] In the compounds of formula (AA-I), P stands for a structural unit -O-CH 2 -CH 2 -, -O-CH(CH 3 )-CH 2 - or -O-CH 2 -CH(CH 3 )-. The number of structural units contained in the compounds of formula (AA-I) is given by the index number s. The structural units P are aligned such that the oxygen atom in each grouping -O-CH 2 -CH 2 -, -O-CH(CH 3 )-CH 2 - and -O-CH 2 -CH(CH 3 )- is adjacent to the alkyl radical R4, and the respective unit -CH2- or -CH(CH3)- is adjacent to the hydroxy group -OH.

[0163] If s is a number greater than 1, the compounds of formula (AA-I) contain multiple structural units P. In this case, each structural unit P can be chosen independently of the other structural units P.

[0164] The index number s stands for an integer from 1 to 60, preferably for an integer from 1 to 40, more preferably for an integer from 10 to 30 and most preferably for an integer from 10 to 20.

[0165] Therefore, a composition according to the invention is further characterized in that it contains (a4) at least one addition product of C 1 -C 6 alkylene oxide(s) onto aliphatic C1-C24 alkanols of the formula (AA-I), wherein R4 represents a saturated or unsaturated C 1 -C 12 alkyl group, particularly preferably a C 1 -C 6 alkyl group, and P represents a structural unit -O-CH 2 -CH 2 -, -O-CH(CH 3 )-CH 2 - or -O-CH 2 -CH(CH 3 )-, and s represents an integer from 1 to 60, preferably an integer from 1 to 40, more preferably an integer from 10 to 30 and most preferably an integer from 10 to 20.

[0166] A particularly suitable addition product of C 1 -C 6 alkylene oxide(s) with aliphatic C 1 -C 24 alkanols of formula (AA-I) is propylene glycol monobutyl ether, also known as PPG-14 butyl ether and bearing the CAS number 9003-13-8. PPG-14 butyl ether can be purchased commercially from Dow under the trade name Ucon Fluid AP.

[0167] In a further particularly preferred embodiment, an agent according to the invention is therefore further characterized in that it contains (a4) PPG-14 butyl ether.

[0168] The alkoxylated alkanols (a4) are particularly preferably used in certain amount ranges in the agent according to the invention.

[0169] Particularly good results were obtained when the agent - based on the total weight of the agent - contained one or more alkoxylated alkanols (a4) in a total amount of 0.1 to 20.0 wt.%, preferably 0.2 to 15.0 wt.%, more preferably 0.3 to 10.0 wt.%, even more preferably 0.4 to 5.0 wt.% and most preferably 0.5 to 3.0 wt.%.

[0170] Within the scope of a further preferred embodiment, an agent according to the invention is characterized in that it contains - based on the total weight of the agent - one or more addition products of C 1 -C 6 alkylene oxide(s) with aliphatic C 1 -C 24 alkanols (a4) in a total amount of 0.1 to 20.0 wt.%, preferably 0.2 to 15.0 wt.%, more preferably from 0.3 to 10.0 wt.%, even more preferably from 0.4 to 5.0 wt.%, even more preferably from 0.5 to 3.0 wt.% and very particularly preferably from 0.5 to 1.5 wt.%. pH value of the agents

[0171] The pH of the agent according to the invention is preferably adjusted to a slightly acidic to alkaline pH. The agent particularly preferably has an alkaline pH in the range from 3.8 to 11.5, preferably from 4.0 to 10.0, and more preferably from 5.0 to 9.0, and most preferably from 6.0 to 8.0.

[0172] In a further particularly preferred embodiment, an agent according to the invention is characterized in that it contains water and has a pH value of 3.8 to 11.5, preferably of 4.0 to 10.0, more preferably of 5.0 to 9.0 and most preferably of 6.0 to 8.0.

[0173] To adjust the desired pH, the agent according to the invention may contain at least one acidifying agent and / or alkalizing agent. The pH values ​​within the meaning of the present invention are pH values ​​measured at a temperature of 22°C.

[0174] As alkalizing agents, the agents can contain, for example, ammonia, alkanolamines and / or basic amino acids.

[0175] The alkanolamines usable in the agent according to the invention are preferably selected from primary amines having a C 2 -C 6 alkyl parent structure carrying at least one hydroxyl group. Preferred alkanolamines are selected from the group consisting of 2-aminoethan-1-ol (monoethanolamine), 3-aminopropan-1-ol, 4-aminobutan-1-ol, 5-aminopentan-1-ol, 1-aminopropan-2-ol, 1-aminobutan-2-ol, 1-aminopentan-2-ol, 1-aminopentan-3-ol, 1-aminopentan-4-ol, 3-amino-2-methylpropan-1-ol, 1-amino-2-methylpropan-2-ol, 3-aminopropan-1,2-diol, and 2-amino-2-methylpropan-1,3-diol.

[0176] Particularly preferred alkanolamines according to the invention are selected from 2-aminoethane-1-ol and / or 2-amino-2-methylpropane-1-ol. A particularly preferred embodiment is therefore characterized in that the agent according to the invention contains an alkanolamine selected from 2-aminoethane-1-ol and / or 2-amino-2-methylpropane-1-ol as an alkalizing agent.

[0177] An amino acid within the meaning of the invention is an organic compound that contains at least one protonatable amino group and at least one -COOH or -SO 3 H group in its structure. Preferred amino acids are aminocarboxylic acids, in particular α-(alpha)-aminocarboxylic acids and ω-aminocarboxylic acids, with α-aminocarboxylic acids being particularly preferred.

[0178] According to the invention, basic amino acids are understood to be amino acids which have an isoelectric point pl of greater than 7.0.

[0179] Basic α-aminocarboxylic acids contain at least one asymmetric carbon atom. Within the scope of the present invention, both possible enantiomers can be used equally as specific compounds or as mixtures thereof, particularly as racemates. However, it is particularly advantageous to use the naturally occurring isomer form, usually in the L-configuration.

[0180] The basic amino acids are preferably selected from the group consisting of arginine, lysine, ornithine, and histidine, particularly preferably arginine and lysine. In another particularly preferred embodiment, an agent according to the invention is characterized in that the alkalizing agent is a basic amino acid from the group consisting of arginine, lysine, ornithine, and / or histidine.

[0181] In addition, the agent may contain other alkalizing agents, particularly inorganic alkalizing agents.

[0211] The agent described above is a ready-to-use agent that can be applied to the keratinous material. This ready-to-use agent preferably has a high water content. It has been found that agents that contain – based on the total weight of the agent – ​​50.0 to 98.0 wt.%, preferably 60.0 to 90.0 wt.%, and particularly preferably 70.0 to 90.0 wt.% water are particularly suitable.

[0212] In a further explicitly very particularly preferred embodiment, an agent according to the invention is characterized in that it contains - based on the total weight of the agent - 50.0 to 98.0 wt.%, preferably 60.0 to 90.0 wt.% and particularly preferably 70.0 to 90.0 wt.% water. Process for coloring keratin material

[0213] The agents described above can be used excellently in processes for coloring keratin material, especially human hair.

[0214] A second object of the present invention is therefore a process for dyeing keratin material, in particular human hair, comprising the following steps: (1) applying a colorant to the keratinic material, wherein the colorant is an agent as disclosed in detail in the description of the first subject matter of the invention, (2) allowing the colorant to act on the keratinic material, and (3) rinsing the colorant out.

[0215] In step (1) of the method according to the invention, the agent of the first subject matter of the invention is applied to the keratinic material, which is most preferably human hair.

[0216] In step (2) of the method according to the invention, the agent is then allowed to act on the keratin material after its application. Various exposure times, for example, from 30 seconds to 60 minutes, are conceivable.

[0217] A major advantage of the coloring system according to the invention, however, is that an intense color result can be achieved even in very short periods of time after short exposure times. For this reason, it is advantageous if the application mixture remains on the keratin material for only a comparatively short period of time, from 30 seconds to 15 minutes, preferably from 30 seconds to 10 minutes, and particularly preferably from 1 to 5 minutes, after application.

[0218] In a further preferred embodiment, a method according to the invention is characterized by (2) the coloring agent acting on the keratinic material for a period of time from 30 seconds to 15 minutes, preferably from 30 seconds to 10 minutes, and particularly preferably from 1 to 5 minutes.

[0219] After the application mixture has acted on the keratin material, it is finally rinsed out in step (3) of the process.

[0220] In one embodiment, the application mixture can be washed out with water alone, i.e., without the aid of a post-treatment agent or shampoo. The application of a post-treatment agent or conditioner after step (3) is also conceivable in principle. A process for coloring keratin material, in which the ready-to-use agent is first prepared.

[0221] As already described above, the agent of the first subject matter of the invention is a ready-to-use agent that is either made available to the user directly in its ready-to-use form or that is prepared by mixing different agents shortly before use.

[0222] In order to ensure a particularly fine distribution of the pigments, it has proven particularly preferable to prepare the ready-to-use agent shortly before use by mixing two or three different agents.

[0223] In a particularly preferred embodiment, the ready-to-use agent is prepared by mixing at least two different agents, the first of these two agents comprising a mixture of alkoxylated fatty acid ester (a3) ​​and coloring compound(s), in particular pigment(s) (a2). Thus, the mixture of alkoxylated fatty acid ester (a3) ​​and pigment(s) (a2) can, for example, represent a pre-dispersion provided in the form of a concentrate. The second agent contains at least one amino-functionalized silicone polymer (a1) and can, for example, represent an aqueous, cosmetic carrier formulation.It is also in accordance with the invention if the first agent, which comprises the mixture of alkoxylated fatty acid ester (a3) ​​and pigment(s) (a2), is a water-based cosmetic carrier formulation, and the second agent, which contains the amino-functionalized silicone polymer (a1), is in the form of a concentrate. To prepare the ready-to-use agent, the two aforementioned agents are then shaken or stirred together.

[0224] Furthermore, it is according to the invention that ready-to-use colorants are produced by mixing three previously separately prepared agents, wherein the first agent is a mixture or pre-dispersion of alkoxylated fatty acid ester (a3) ​​and pigment(s) (a2), the second mixture comprises an amino-functionalized silicone polymer (a1) and can be present, for example, in the form of a concentrate, and the third agent is an aqueous cosmetic carrier formulation which preferably contains at least one alkoxylated alkanol (a4).

[0225] A further subject of the present application is therefore a method for dyeing keratin material, in particular human hair, comprising the following steps: (1) Providing an agent (I), wherein the agent (I) contains: (a2) at least one pigment and (a3) ​​at least one addition product of C 1 -C 6 alkylene oxide(s) onto the esters of C 12 -C 30 fatty acids and aromatic C 1 -C 12 alcohols, (2) Providing an agent (II), wherein the agent (II) contains: (a1) at least one amino-functionalized silicone polymer, and (3) Preparing an application mixture by mixing the agent (I) with the agent (II), (4) Applying the application mixture prepared in step (3) to the keratinic material, (5) Allowing the application mixture applied in step (4) to act on the keratinic material, and (6) Rinsing the application mixture with water, wherein the ingredients (a1), (a2) and (a3) ​​have already been disclosed in detail in the description of the first subject matter of the invention.

[0226] The optionally additionally applicable alkoxylated alkanols (a4) can, in the context of this embodiment, be contained, for example, in the agent (I) and / or in the agent (II).

[0227] Depending on the selected pH value, the aminosilicone (a3) ​​has in some cases shown reduced storage stability in aqueous media. In these cases, it may be advantageous to also package the amino-functionalized silicone polymer (a3) ​​in a separate product and to mix both the ingredients (a1) and (a2) as well as the aminosilicone (a3) ​​with a base formulation shortly before use. In this case, at least three different products are mixed together to produce the ready-to-use colorant.

[0228] Particularly preferred is therefore a method for dyeing keratin material, in particular human hair, comprising the following steps: (1) Providing an agent (I), wherein the agent (I) contains: (a2) at least one pigment and (a3) ​​at least one addition product of C 1 -C 6 alkylene oxide(s) onto the esters of C 12 -C 30 fatty acids and aromatic C 1 -C 12 alcohols, (2) Providing an agent (II), wherein the agent (II) contains: (a1) at least one amino-functionalized silicone polymer, and (3) Providing an agent (III), wherein the agent (III) contains: (a4) at least one addition product of C 1 -C 6 alkylene oxide(s) onto aliphatic C 1 -C 24 alkanols, (4) Producing an application mixture by mixing the agent (I) with the agent (II) with the agent (III), (5) Applying the application mixture prepared in step (4) to the keratinic material, (6) Allowing the agents prepared in step (5) applied application mixture on the keratin material and (7) rinsing the application mixture, wherein the ingredients (a1), (a2), (a3) ​​and (a4) have already been disclosed in detail in the description of the first subject matter of the invention.

[0229] In this embodiment, agent (I) preferably represents a predispersion of the pigments (a2) in the alkoxylated fatty acid ester(s) (a3), which may be present, for example, in the form of a concentrate. Agent (II) is preferably also a concentrate containing the amino-functionalized silicone polymer(s) (a1).

[0230] Before application, the two agents or concentrates (I) and (II) are mixed with the carrier formulation (III). The cosmetic carrier formulation or agent (III) contains, in this embodiment, the alkoxylated alkanols (a4).

[0231] The order of mixing is arbitrary. For example, agents (I) and (II) can be mixed together first, followed by mixing this mixture with agent (III). It is also conceivable to first mix agents (II) and (III) and then mix this mixture with agent (I). All three agents (I), (II), and (III) can also be combined and then mixed by shaking or stirring.

[0232] The carrier formulation contains water and preferably has a high water content. The optionally usable additional ingredients of the first subject matter of the invention can also be contained in this carrier formulation.

[0233] Regarding the further preferred embodiments of the methods according to the invention, mutatis mutantis what has been said about the agent according to the invention. Examples 1. Formulations

[0234] The following formulations were prepared (all data in wt. %), unless otherwise stated, whereby Examples 1 and 2 are not according to the invention: Example 1 Example 2 Example 3 Example 4 Cream base Cetyl alcohol 3,57 3,57 3,57 3,57 Stearyl alcohol 1,98 1,98 1,98 1,98 Paraffinum Liquidum 2,08 2,08 2,08 2,08 Ceteareth-30 1,19 1,19 1,19 1,19 Ceteareth-100 0,59 0,59 0,59 0,59 Glyceryl stearate 0,59 0,59 0,59 0,59 Water, distilled 61,67 61,67 61,67 61,67 Potassium dihydrogen phosphate 0,35 0,35 0,35 0,35 Disodium hydrogen phosphate (dihydrate) 0,72 0,72 0,72 0,72 Phenoxyethanol 0,89 0,89 0,89 0,89 Predispersion Unipure Red LC 3079 0,50 --- 0,50 0,38 PPG-3 Benzyl Ether Myristate Crodamol STS-LQ-(MH) 4,95 --- 2,00 1,50 Additive Water, demineralized 19,92 21,87 21,87 22,74 PPG-3 Benzyl Ether Myristate Crodamol STS-LQ-(MH) --- 3,00 --- --- Unipure Red LC 3079 --- 0,50 --- --- PPG-14 Butyl ether UCON FLUID AP --- --- 1,00 1,00 activator DOWSIL AP-8568 Amino Fluid, amino silicone 1,00 1,00 1,00 0,75

[0235] A cream base was first prepared from the specified ingredients. The specified additives were then added to this cream base.

[0236] In the recipe of Example 1, only a portion of water was added to the cream base as an additive.

[0237] In the formulation of Example 2, water, PPG-3 Benzyl Ether Myristate (a3) ​​and the pigment Unipure Red LC 3079 (a2) were successively incorporated into the cream base as additives.

[0238] In the formulations of Examples 3 and 4, water and PPG-14 butyl ether (a4) were added to the cream base as additives.

[0239] For example formulations 1, 3, and 4, the pigment Unipure Red LC 3079 (a2) and PPG-3 Benzyl Ether Myristate (a3) ​​were mixed separately, resulting in a predispersion. This predispersion was then incorporated into the cream base.

[0240] In the final step, the aminosilicone DOWSIL AP-8568 Amino Fluid (a1) was added to all four example formulations 1 to 4. 2. Application

[0241] Strands of hair (Kerling Euronatural hair white) were first measured colorimetrically using a Datacolor colorimeter, type Spectraflash 450.

[0242] The formulations of Examples 1 to 4 were used as hair coloring agents as follows: After preparation, the respective agent was applied to hair strands (Kerling, Euronaturhaar white, liquor ratio: 1 g of agent (E1) per g of hair strand). The agent was left on for three minutes. Following this, the hair strands were thoroughly rinsed with water (1 minute), dried, and then colorimetrically measured again using a Datacolor Spectraflash 450 colorimeter.

[0243] The ΔE value used to assess the color intensity is derived from the L*a*b* color measurement values ​​measured on the respective strand section as follows: ΔE = L i − L 0 2 + a i − a 0 2 + b i − b 0 1 2 L 0 , a 0 and b 0 = measured values ​​of the strand before coloring L i , ai and bi = measured values ​​of the strand after coloring The larger this ΔE value is, the higher (= better) the intensity of the coloring is

[0244] The dyed hair strands were each evaluated for their feel by 10 trained individuals. Hair feel was rated on a scale of 1 to 6 (1: very poor hair feel (rough, brittle, dull), 6: very good hair feel (smooth, soft, well-groomed)).

[0245] The dyed hair strands were also evaluated for their rubbing fastness. To assess rubbing fastness, hair strands were subjected to standardized mechanical abrasion and then colorimetrically measured again. The ΔE value used to assess rubbing fastness is derived from the L*a*b* color values ​​measured on the respective strand section, as follows: ΔE = L i − L 0 2 + a i − a 0 2 + b i − b 0 1 2 L 0 , a 0 and b 0 = measured values ​​of the strand after dyeing L i , ai and bi = measured values ​​of the strand after dyeing and after mechanical stress The larger this ΔE value is, the higher the color shift caused by abrasion, ie the worse the rubbing fastness is.

[0246] After coloring and drying, each strand was subjected to three manual hair washes. For each wash, the strand was moistened, then a commercially available shampoo (Schwarzkopf, Schauma 7 Kräuter) was massaged into the strand for 25 seconds (0.25 g of shampoo per gram of hair). The strand was then rinsed with lukewarm tap water for 30 seconds and dried. After completing the three washes, each strand was colorimetrically measured again.

[0247] The ΔE value used to assess wash fastness is derived from the measured L*a*b* color values ​​as follows: ΔE = L i − L 0 2 + a i − a 0 2 + b i − b 0 1 2 L 0 , a 0 and b 0 = measured values ​​of the dyed strand after dyeing and before washing L i , ai and bi = measured values ​​of the dyed strand after 3 hair washes The larger this ΔE value is, the higher the color shift caused by washing, ie the worse the wash fastness is.

[0248] The following results were obtained: Example 1 Example 2 Example 3 Example 4 Color intensity, ΔE value (before staining - after staining) 67 69 69 67 Wash fastness, ΔE value (before washing - after 3 washes) 14 19 14 11 Rub fastness, ΔE value (before abrasion - after abrasion) 11 18 8 7 Hair feel / hair grip 2 3 2,2 2,2
