The present invention also relates to a method for dyeing keratin materials using the aforementioned agent on keratin materials.

Description

[0001] The subject of this application is a reagent for staining keratin materials, particularly human hair, comprising at least one amino-functionalized siloxane polymer (a1), at least one coloring compound (a2), and at least one addition product of C1-C6 oxidized olefins with esters of fatty acids and aromatic alcohols.

[0002] The second subject of this application is a method for staining keratin materials, particularly human hair, wherein the reagent of the first subject of this invention is applied to the keratin material to make it function, and then washed off with water.

[0003] Modifying the shape and color of keratin materials, especially human hair, is an important area of ​​modern cosmetics. To alter hair color, those skilled in the art understand various hair dyeing systems based on the requirements of hair coloring. Oxidative dyes are commonly used for permanent, strong dyeing, exhibiting good fastness properties and excellent gray coverage. These colorants contain an oxidative dye precursor, a so-called developer component, and a colorant component, which interact to form the actual dye under the influence of an oxidizing agent such as hydrogen peroxide. Oxidative dyes are characterized by their extremely long-lasting coloring effect.

[0004] When using direct dyes, the dye diffuses directly from the colorant into the hair fibers. Compared to oxidative dyeing, hair dyes obtained with direct dyes have a shorter shelf life and are washable more quickly. Direct dyes typically remain on the hair for 5 to 20 washes.

[0005] It is known that the use of colored pigments can cause short-term color changes in hair and / or skin. Colored pigments are generally considered insoluble dyeing substances. They exist as small particles, undissolved in the dye formulation, and are deposited only externally on the hair fibers and / or skin surface. Therefore, they can usually be removed again without residue after several washes with detergents containing surfactants. Various products of this type are marketed under the name "hair mascara."

[0006] If a user desires exceptionally long-lasting color, using oxidative dyes is their only option. However, despite numerous optimization attempts, the unpleasant ammonia or amine odor cannot be completely eliminated in oxidative hair dyeing. Hair damage still associated with the use of oxidative dyes also negatively impacts the user's hair. Therefore, finding alternative high-performance coloring processes remains an ongoing challenge. For this reason, pigment-based colorants are very popular. However, the color strength and fastness properties of pigment-based colorants, in particular, still require significant improvement.

[0007] The objective of this invention is to provide a colorant capable of fixing pigments to hair in an extremely durable manner. When used in the dyeing process, a particularly strong dyeing effect should be obtained. Furthermore, dyeing with good wash resistance, good leveling ability, and a particularly uniform color result should be achieved. In addition, the abrasion resistance of these pigment colorants should also be particularly low, meaning that the colorant should have particularly good rubbing fastness even in mechanical contact with clothing or other textiles. Moreover, keratin materials, especially hair, should not feel heavy, dull, or greasy after application of the pigment colorant, and should have the most pleasant feel possible.

[0008] Surprisingly, it has now been found that if a siloxane polymer containing at least one amino-functionalized compound (a1), at least one colorant compound (a2), and C1-C6 oxidized olefins are used with C 12 -C 30 Fatty acids and C1-C 12 The above problems can be well solved by using reagents of at least one addition product (a3) ​​of an aromatic alcohol ester to stain keratin materials, especially hair.

[0009] The first subject of this invention is a reagent for staining keratin materials, particularly human hair, comprising: (a1) at least one amino-functionalized siloxane polymer, and (a2) at least one color-imparting compound, and (a3) C1-C6 oxides and C 12 -C 30 Fatty acids and C1-C 12 At least one addition product of an ester of an aromatic alcohol.

[0010] In the course of work leading to this invention, it has been surprisingly shown that the use of alkoxylated fatty acid esters (a3) ​​in reagents containing aminosiloxanes (a1) and coloring compounds (a2) results in improved color intensity and wash fastness when the reagent is applied to keratin materials, particularly in the dyeing process of human hair. These positive effects are particularly observed when the coloring compound (a2) is a pigment.

[0011] Keratin materials Keratin materials include hair, skin, and nails (such as fingernails and / or toenails). Wool, fur, and feathers also fall within the definition of keratin materials.

[0012] Preferably, keratin material is understood to refer to human hair, human skin, and human nails, especially fingernails and toenails. Keratin material is understood to refer specifically to human hair.

[0013] Colorant In the context of this invention, the term "colorant" is used for the dyeing of keratin materials, particularly hair, which is caused by the use of coloring compounds, especially pigments. In this dyeing process, the pigment, as a coloring compound, is deposited as a particularly homogeneous, uniform, and smooth film on the surface of the keratin material.

[0014] The reagent according to the invention comprises essential components (a1), (a2) and (a3), preferably in a cosmetic carrier.

[0015] Amino-functionalized siloxane polymers (a1) As an essential first component (a1) of the present invention, the reagent contains at least one amino-functionalized siloxane polymer. The amino-functionalized siloxane polymer may alternatively be referred to as aminosiloxane or amino-terminated polydimethylsiloxane.

[0016] Siloxane polymers are typically macromolecules with a molecular weight of at least 500 g / mol, preferably at least 1000 g / mol, more preferably at least 2500 g / mol, and particularly preferably at least 5000 g / mol, containing repeating organic units.

[0017] The maximum molecular weight of a siloxane polymer depends on the degree of polymerization (the number of monomers) and the batch size, and is also partly determined by the polymerization method. For the purposes of this invention, it is preferred that the maximum molecular weight of the siloxane polymer is not greater than 10. 7 g / mol, preferably not greater than 10 g / mol 6 g / mol, preferably not greater than 10 g / mol. 5 g / mol.

[0018] Siloxane polymers contain many repeating Si-O units, and the Si atoms may carry organic groups, such as alkyl or substituted alkyl groups. Optionally, siloxane polymers are therefore also called polydimethylsiloxanes.

[0019] Corresponding to the high molecular weight of the siloxane polymer, these are based on more than 10 Si-O repeating units, preferably more than 50 Si-O repeating units, more preferably more than 100 Si-O repeating units, and most preferably more than 500 Si-O repeating units.

[0020] Amino-functionalized siloxane polymers are understood as functionalized siloxanes carrying at least one structural unit with an amino group. Preferably, amino-functionalized siloxane polymers carry multiple structural units, each having at least one amino group. The amino group is understood to refer to primary, secondary, and tertiary amino groups. All of these amino groups can be protonated in an acidic environment and then exist in their cationic form.

[0021] In principle, good results can be obtained if the amino-functionalized siloxane polymer (a1) contains at least one primary amino group, at least one secondary amino group, and / or at least one tertiary amino group. However, when an amino-functionalized siloxane polymer (a1) containing at least one secondary amino group is used in the reagent, staining with the best wash fastness is observed.

For example, the silicon atom adjacent to the asterisk can be bonded to another oxygen atom, and the oxygen atom adjacent to the asterisk can be bonded to another silicon atom or even to a C1-C6 alkyl group.

[0027] Divalent C1-C 20 Alkylenes can also be referred to as divalent or divalent C1-C. 20 Alkylene, which means that each ALK1 or AK2 group can form two bonds.

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

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

[0030] Straight-chain bivalent C1-C 20 Examples of alkylene groups include methylene (-CH2-), ethylene (-CH2-CH2-), propylene (-CH2-CH2-CH2-), and butylene (-CH2-CH2-CH2-CH2-). Propylene (-CH2-CH2-CH2-) is particularly preferred. Divalent alkylene groups can also be branched, starting with a chain length of 3 carbon atoms.

If, after this time, undissolved components of the pigment are still visible in the mixture, the solubility of the pigment is less than 0.5 g / L. If the pigment-water mixture cannot be visually assessed due to the high intensity of the potentially finely dispersed pigment, the mixture is filtered. If a certain proportion of undissolved pigment remains on the filter paper, the solubility of the pigment is less than 0.5 g / L.

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

Particularly preferred pearlescent pigments are based on natural or synthetic mica and coated with one or more of the aforementioned metal oxides.

The particles can be, for example, an inorganic matrix, which may be aluminum, silica, calcium borosilicate, calcium aluminum borosilicate, or even aluminum.

[0077] For example, alizarin colored varnish can be used.

[0078] Due to their excellent lightfastness and temperature resistance, the above-mentioned pigments are particularly preferred for use in reagents. It is also preferred that the pigments used have a certain particle size. Therefore, according to the invention, it is advantageous that at least one pigment has an average particle size D. 50 The particle size is 1.0-50 µm, preferably 5.0-45 µm, more preferably 10-40 µm, and particularly 14-30 µm.

Based on the total weight of the reagent, particularly good results are obtained when the reagent contains one or more pigments (a2) in a total amount of 0.01-10.0 wt.%, preferably 0.1-5.0 wt.%, more preferably 0.2-2.5 wt.%, and very preferably 0.25-1.5 wt.%.

[0080] In another very particularly preferred embodiment, the reagent according to the invention is characterized in that, based on the total weight of the reagent, the reagent contains one or more pigments in a total amount of 0.01-10.0 wt.%, preferably 0.1-5.0 wt.%, more preferably 0.2-2.5 wt.%, and very particularly preferably 0.25-1.5 wt.%, based on the total weight of the reagent (a2).

[0081] As a coloring compound (a2), the reagent according to the invention may also contain one or more direct dyes. Direct dyes are dyes that are directly attracted to hair and do not require an oxidation process to form color. Direct dyes are typically nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinones, triarylmethane dyes, or indophenols.

[0082] Direct dyes within the scope of this invention have a solubility greater than 0.5 g / L in water (760 mmHg) at 25°C and are therefore not considered pigments. Preferably, direct dyes within the scope of this invention have a solubility greater than 1.0 g / L in water (760 mmHg) at 25°C.

[0083] Direct dyes can be classified into anionic direct dyes, cationic direct dyes, and nonionic direct dyes.

[0084] In a further preferred embodiment, the method according to the invention is characterized in that the reagent comprises at least one colorant compound (a2) selected from anionic, nonionic and cationic direct dyes.

[0085] Suitable cationic direct dyes include 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 (Cat Blue 347 / Dystar), HC Blue 16, Basic Blue 99, Basic Brown 16, Basic Brown 17, Basic Yellow 57, Basic Yellow 87, Basic Orange 31, Basic Red 51, and Basic Red 76.

[0086] As nonionic direct dyes, nonionic nitro and quinone dyes, as well as neutral azo dyes, can be used. Suitable nonionic direct dyes are those listed under the following international names or trade names: 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, and 1,4-diamino-2-nitrobenzene, 2-amino-4-nitrophenol, 1,4-bis-(2-hydroxyethyl)-amino-2-nitrobenzene, 3-nitro-4-(2-hydroxyethyl)-aminophenol. 2-(2-hydroxyethyl)amino-4,6-dinitrophenol, 4-[(2-hydroxyethyl)amino)-3-nitro-1-methylbenzene, 1-amino-4-(2-hydroxyethyl)amino-5-chloro-2-nitrobenzene, 4-amino-3-nitrophenol, 1-(2'-ureidoethyl)amino-4-nitrobenzene, 2-[(4-amino-2-nitrophenyl)amino]benzoic acid, 6-nitro-1,2,3,4-tetrahydroquinoxaline, 2-hydroxy-1,4-naphthoquinone, picric acid and its salts, 2-amino-6-chloro-4-nitrophenol, 4-ethylamino-3-nitrobenzoic acid and 2-chloro-6-ethylamino-4-nitrophenol.

[0087] Anionic direct dyes are also known as acid dyes. Acid dyes are direct dyes having at least one carboxylic acid group (-COOH) and / or one sulfonic acid group (-SO3H). Depending on the pH value, the protonated form of the carboxylic acid or sulfonic acid group (-COOH, -SO3H) and their deprotonated form (present -COO) will react with each other. - -SO3 - Balance. The proportion of the protonated form increases as pH decreases. If the direct dye is used in its salt form, the carboxylic acid or sulfonic acid groups are present in a deprotonated form and neutralized by the corresponding stoichiometric cations to maintain electroneutrality. The acid dyes of the present invention can also be used in their sodium and / or potassium salt forms.

[0088] Acid dyes within the scope of this invention have a solubility greater than 0.5 g / L in water (760 mmHg) at 25°C and are therefore not considered pigments. Preferably, acid dyes within the scope of this invention have a solubility greater than 1.0 g / L in water (760 mmHg) at 25°C.

[0089] Alkaline earth metal salts (such as calcium and magnesium salts) or aluminum salts of acid dyes typically have lower solubility than their corresponding alkali metal salts. If the solubility of these salts is below 0.5 g / L (25°C, 760 mmHg), they do not fall within the definition of direct dyes.

[0090] A fundamental characteristic of acid dyes is their ability to form anionic charges, and the carboxylic acid or sulfonic acid group responsible for this is typically linked to different chromophore systems. For example, suitable chromophore systems can be found in the structures of nitrophenylenediamine, nitroaminophenol, azo dyes, anthraquinone dyes, triarylmethane dyes, xanthannaphthalene dyes, rhodamine dyes, oxazine dyes, and / or indophenol dyes.

[0091] In another embodiment, the method for staining keratin materials is characterized in that the reagent comprises at least one anionic direct dye selected from nitrophenylenediamine, nitroaminophenol, azo dyes, anthraquinone dyes, triarylmethane dyes, xanthannaphthalene dyes, rhodamine dyes, oxazine dyes, and / or indophenol dyes, wherein each dye from the above group has at least one carboxylic acid group (-COOH), sodium carboxylate group (-COONa), potassium carboxylate group (-COOK), sulfonic acid group (-SO3H), sodium sulfonate group (-SO3Na), and / or potassium sulfonate group (-SO3K).

[0093] For example, the water solubility of anionic direct dyes can be determined as follows: Add 0.1 g of anionic direct dye to a beaker. Add a stir bar. Then add 100 ml of water. While stirring, heat the mixture to 25°C on a magnetic stirrer. Stir for 60 minutes. Then visually evaluate the aqueous mixture. If undissolved residues remain, increase the amount of water—for example, in 10 ml increments. Add water until the dye is completely dissolved. If the dye-water mixture cannot be visually evaluated due to the high strength of the dye, filter the mixture. If some undissolved dye remains on filter paper, repeat the solubility test with a larger amount of water. If 0.1 g of anionic direct dye dissolves in 100 ml of water at 25°C, the solubility of the dye is 1.0 g / L.

[0097] 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.

[0098] Acid Orange 7 is the sodium salt of 4-[(2-hydroxy-1-naphthyl)azo]benzenesulfonic acid. Its water solubility is greater than 7 g / L (25℃).

Aromatic C1-C 12 The structure of alcohols can also include other heteroatoms, such as oxygen or nitrogen.

[0115] The corresponding aromatic C1-C 12 Alcohols can be monohydric or polyhydric, meaning they can have one or more hydroxyl groups.

[0116] One Yuan Fangzu C1-C 12 Alcohols are particularly preferred. These compounds contain exactly one hydroxyl group. Suitable examples include phenol, benzyl alcohol, 2-phenylethanol, and 2-phenoxyethanol.

[0117] Therefore, reagents for staining keratin materials, especially human hair, are particularly preferred and contain...

[0123] As previously mentioned, particularly suitable C1-C6 olefin oxides include ethylene oxide (1,2-ethylene oxide), propylene oxide (1,2-propylene oxide), and butane oxide (1,2-butane and 2,3-butane). Ethylene oxide (1,2-ethylene oxide) and propylene oxide (1,2-propylene oxide) are obviously very particularly preferred. Propylene oxide (1,2-propylene oxide) is the most preferred.

[0126] If C 12 -C 30 Fatty acids themselves react with ethylene oxide, starting from C... 12 -C 30 The carboxylic acid group of the fatty acid and ethylene oxide initially form an adduct, forming a group. -C(O)-O-CH2-CH2-O- This group is also an ester. If one mole of fatty acid reacts with one mole of ethylene oxide, on average, one unit is formed. -CH2-CH2-O- A simple adduct. However, depending on the molar excess of ethylene oxide used, multiple adducts can also be formed, with each mole of C... 12 -C 30 Fatty acids exist in several units -CH2-CH2-O- To form the ester (a3), the adduct is then further reacted with at least one aromatic C1-C... 12 Alcohol reaction. The positions marked with an asterisk indicate the bonds with the remaining fatty acid and the remaining alcohol.

[0127] If C 12 -C 30 Fatty acids react similarly to propylene oxide, and can first be derived from C... 12 -C 30 The carboxylic acid group of the fatty acid and propylene oxide begin to form an adduct, thereby forming a group. -C(O)-O-CH(CH3)-CH2-O- or groups -C(O)-O-CH2-CH(CH3)-O- Typically, a mixture of the two groups mentioned above is obtained in the reaction mixture. Both groups are also esters. If one mole of fatty acid reacts with one mole of propylene oxide, the average number of esters formed is [number missing]. -CH(CH3)-CH2-O- and -CH2-CH(CH3)-O- A simple adduct of a mixture of propylene oxide and hydroxyl groups. However, depending on the molar excess of propylene oxide used, multiple adducts can also be formed, wherein each mole of C... 12 -C 30 Fatty acids exist in several units -CH(CH3)-CH2-O- and / or -CH2-CH(CH3)-O- To form the ester (a3), the adduct is then further reacted with at least one aromatic C1-C... 12 Alcohol reaction. The positions marked with an asterisk indicate the bonds with the remaining fatty acid and the remaining alcohol.

[0128] In addition, C can be considered in principle. 12 -C 30 Fatty acids react with a mixture of ethylene oxide and propylene oxide. In this case, a mixture of the above-mentioned adducts is formed. In this way, higher oxidized alkenes, such as butane oxide, react with C... 12 -C 30 Reactions of fatty acids are also possible.

[0129] Addition products prepared in this manner result in, for example, alkoxylated fatty acid esters of the general formula (AFE-I).

[0139] When o is a number greater than 1, the compound of formula (AFE-I) (or formula (AFE-II)) contains multiple structural units Q, in which case each structural unit Q can be selected independently of the other structural units Q.

[0140] Therefore, the preferred reagent according to the invention is characterized in that it comprises: (a3) ​​at least one alkoxylated fatty acid ester of general formula (AFE-I). (AFE-I) in R1 represents saturated or unsaturated C. 11 -C 29 alkyl R2 and R3 independently represent a hydrogen atom, a C1-C6 alkyl group, a hydroxyl group, or a C1-C6 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 the structural unit -O-CH2-CH2-, -O-CH(CH3)-CH2-, or -O-CH2-CH(CH3)-.

[0146] In alkoxylated fatty acid esters of general formula (AFE-II), the structural unit Q is arranged such that the oxygen atom in the group -O-CH(CH3)-CH2- and / or -O-CH2-CH(CH3)- is adjacent to the benzyl group, and the corresponding unit -CH2- or -CH(CH3)- is adjacent to the ester group -OC(O)-R1.

[0147] One particularly suitable compound of this type is PPG-3 benzyl ether myristate, also known as α-(1-oxytetradecyl)-ω-(phenylmethoxy)poly[oxy(methyl-1,2-ethylenediyl)] with CAS number 642443-86-5.

[0148] PPG-3 benzyl ether myristate can be purchased from Croda, for example, under the trade name Crodamol STS.

[0149] In another very particularly preferred embodiment, the reagent according to the invention is characterized in that it contains (a3)PPG-3 benzyl ether myristate.

[0150] When esters contain C1-C6 oxidized alkenes, there is an interaction between ethylene oxide and C... 12 -C 30 Fatty acids and aromatic C1-C 12 Another type of adduct of alcohol esters (a3), said ester being formed by C1-C2. 12 Aromatic alcohol esterification of C with at least one hydroxyl group 12 -C 30 It is obtained from fatty acids. For example, ricinoleic acid ((9Z,12R)-12-hydroxy-9-octadecenoic acid) can be first esterified with benzyl alcohol, phenol, 2-phenylethanol, or 2-phenoxyethanol. When these adducts are formed, one or more C1-C6 oxidized alkenes are then attached to the hydroxyl groups of ricinoleic acid.

[0151] If each mole of fatty acid reacts with 1 mole of C1-C6 olefin oxide, then, if, for example, ethylene oxide is used as the olefin oxide, one unit... -CH2-CH2-O- It can add to the hydroxyl group of ricinoleic acid. However, depending on the molar excess of ethylene oxide used, multiple adducts can also be formed, combining several units. -CH2-CH2-O- Addition to each hydroxyl group of the fatty acid, and / or addition of several units -CH2-CH2-O- It also adds to each free hydroxyl group of glycerol.

[0155] In the work leading to this invention, it has been found that the presence of one or more previously described alkoxylated fatty acid esters (a3) ​​optimizes the dispersion of the coloring compound (a2) in the reagents according to the invention, particularly when these are pigments. It is believed that pigments dispersed so finely in the reagents in this manner can be applied very uniformly and as a fine, resistant film onto keratin materials, meaning that the rubbing fastness of the dye obtained in this way is particularly good. Furthermore, this particularly fine dispersion of the pigments in the reagents is also considered a reason for the good wash fastness achievable using the reagents of this invention.

[0156] Therefore, very good results were obtained when alkoxylated fatty acid esters (a3) ​​were included in the reagents of the present invention as the main dispersant or additive. Further work has shown that this effect can be further enhanced if a further C1-C6 oxidized olefinic adduct (a4) is added to the reagent.

[0215] Reagent moisture content The above-described reagent is a ready-to-use reagent applicable to keratin materials. This ready-to-use reagent preferably has a high water content. It has been found that reagents containing 50.0 to 98.0 wt.%, preferably 60.0 to 90.0 wt.%, and particularly preferably 70.0 to 90.0 wt.%, of water based on the total weight of the reagent are particularly suitable.

[0216] In another clearly very particularly preferred embodiment, the reagent according to the invention is characterized in that, based on the total weight of the reagent, it contains 50.0 to 98.0 wt.%, preferably 60.0 to 90.0 wt.%, and particularly preferably 70.0 to 90.0 wt.% water.

[0217] Staining methods for keratin materials The above reagents can be used well in dyeing keratin materials, especially in dyeing methods for human hair.

[0218] Therefore, a second object of the present invention is a method for staining keratin materials, particularly human hair, comprising the following steps: (1) Applying a staining reagent to the keratin material, wherein the staining reagent is a reagent disclosed in detail in the description of the first subject matter of the present invention. (2) Expose the staining reagent to the keratin material, and (3) Rinse off the staining reagent.

[0219] In step (1) of the method according to the invention, the reagent of the first invention is applied to a keratin material, which is most preferably human hair.

[0220] In step (2) of the method according to the invention, the reagent is then allowed to act on the keratin material after its application. In this case, different exposure times, such as 30 seconds to 60 minutes, are conceivable.

[0221] However, the main advantage of the staining system according to the invention is that strong color results can be obtained in a very short time, even after a short exposure time. Therefore, it is advantageous if the applied mixture remains on the keratin material for a relatively short time after application, from 30 seconds to 15 minutes, preferably from 30 seconds to 10 minutes, and particularly preferably 1 to 5 minutes.

[0222] In another preferred embodiment, the method according to the invention is characterized by: (2) exposing the staining reagent to the keratin material for 30 seconds to 15 minutes, preferably 30 seconds to 10 minutes, and most preferably 1 to 5 minutes.

[0223] After the mixture is applied to the keratin material, it is finally rinsed off in step (3) of the method.

[0224] In one embodiment described herein, the mixture can be washed off with water alone, without the aid of a post-treatment agent or shampoo. The use of a post-treatment agent or conditioner after step (3) is also conceivable in principle.

[0225] The method for staining keratin materials first involves preparing ready-to-use reagents.

[0226] As previously stated, the reagents of the first subject invention are ready-to-use reagents, which are either provided directly to the user in their ready-to-use form or prepared by mixing various reagents before application.

[0227] To ensure a particularly fine distribution of the pigment, it has been shown that it is especially preferable to prepare ready-to-use reagents by mixing two or three different reagents shortly before application.

[0228] Therefore, in a particularly preferred embodiment, a ready-to-use reagent is prepared by mixing at least two different reagents, the first of which comprises a mixture of an alkoxylated fatty acid ester (a3) ​​and a color-providing compound, particularly a pigment (a2). For example, the mixture of alkoxylated fatty acid ester (a3) ​​and pigment (a2) may represent a pre-dispersion provided in concentrate form. The second reagent comprises at least one amino-functionalized siloxane polymer (a1) and may be, for example, an aqueous cosmetic carrier formulation. This is also according to the invention if the first reagent, comprising the mixture of alkoxylated fatty acid ester (a3) ​​and pigment (a2), is an aqueous cosmetic carrier formulation, and the second reagent, comprising the amino-functionalized siloxane polymer (a1), is in concentrate form. The two reagents are then shaken or stirred together to prepare the ready-to-use reagent.

[0229] Furthermore, according to the present invention, a ready-to-use dyeing reagent is prepared by mixing three reagents previously prepared separately, wherein the first reagent is a mixture or pre-dispersion of alkoxylated fatty acid esters (a3) ​​and pigments (a2), the second mixture contains amino-functionalized siloxane polymers (a1) and may be in the form of, for example, a concentrate, and the third reagent is an aqueous cosmetic carrier formulation, which preferably contains at least one alkoxylated alkanol (a4).

[0230] Therefore, another subject of this application is a method for staining keratin materials, particularly human hair, comprising the following steps: (1) Provide reagent (I), wherein reagent (I) comprises: (a2) at least one pigment, and (a3) C1-C6 oxides and C 12 -C 30 Fatty acids and C1-C 12 (2) An addition product of an ester of an aromatic alcohol. (2) Provides reagent (II), wherein reagent (II) comprises: (a1) at least one amino-functionalized siloxane polymer, and (3) An application mixture is prepared by mixing reagent (I) with reagent (II). (4) Apply the application mixture prepared in step (3) onto the keratin material. (5) Expose the application mixture applied in step (4) to the keratin material; and (6) Rinse the application mixture with water. The components (a1), (a2) and (a3) ​​have been disclosed in detail in the description of the first subject matter of the present invention.

[0231] In the context of this embodiment, optionally additionally applicable alkoxylated alkanols (a4) may be present, for example, in reagent (I) and / or reagent (II).

[0232] Depending on the selected pH value, aminosiloxane (a3) ​​exhibits reduced storage stability in aqueous environments in certain cases. In these cases, it may be advantageous to use the amino-functionalized siloxane polymer (a3) ​​in a separate reagent, and only shortly before use, to mix components (a1) and (a2) along with the aminosiloxane (a3) ​​with the base formulation. In this case, at least three different reagents are mixed together to produce a ready-to-use colorant.

[0233] Therefore, a particularly preferred method for staining keratin materials, especially human hair, includes the following steps: (1) Provide reagent (I), wherein reagent (I) comprises: (a2) at least one pigment, and (a3) C1-C6 oxides and C 12 -C 30 Fatty acids and C1-C 12 (2) An addition product of an ester of an aromatic alcohol. (2) Provides reagent (II), wherein reagent (II) comprises: (a1) at least one amino-functionalized siloxane polymer, and (3) Provide reagent (III), wherein reagent (III) comprises: a4) C1-C6 oxides and aliphatic C1-C 24 At least one addition product of an alkanol (a4) (4) An application mixture is prepared by mixing reagent (I) with reagent (II) and optionally with reagent (III). (5) Apply the application mixture prepared in step (4) onto the keratin material. (6) Expose the application mixture applied in step (5) to the keratin material; and (7) Rinse off the applied mixture. The components (a1), (a2), (a3) ​​and (a4) have been disclosed in detail in the description of the first subject matter of the present invention.

[0234] In this embodiment, reagent (I) preferably represents a pre-dispersion of pigment (a2) in alkoxylated fatty acid ester (a3), which may be in the form of, for example, a concentrate. Reagent (II) is also preferably a concentrate containing an amino-functionalized siloxane polymer (a1).

[0235] Prior to application, the two reagents or concentrates (I) and (II) are mixed with the carrier formulation (III). In this embodiment, the cosmetic carrier formulation or reagent (III) comprises an alkoxylated alkanol (a4).

[0236] The order of mixing is arbitrary. Therefore, reagents (I) and (II) can be mixed together first, and then that mixture can be mixed with reagent (III). Similarly, it is conceivable to mix reagents (II) and (III) first, and then that mixture can be mixed with reagent (I). Furthermore, all three reagents (I), (II), and (III) can be added together and then mixed by first shaking or stirring.

[0237] The carrier formulation contains water, preferably with a high water content. Other optional and applicable components of the first invention may also be included in the carrier formulation.

[0238] For a further preferred embodiment of the method according to the invention, refer to the content already stated regarding the reagents according to the invention.

[0240] First, a cream base is prepared using the specified ingredients. Then, the specified additives are added to the cream base.

[0241] In the formulation of Example 1, only a certain proportion of water was added as an additive to the cream base.

[0242] In the formulation of Example 2, water, PPG-3 benzyl ether myristate (a3), and pigment Unipure Red LC3079 (a2) were successively incorporated into the cream base as additives.

[0243] In the formulations of Examples 3 and 4, water and PPG-14 butyl ether (a4) were added as additives to the cream base.

[0244] In formulations 1, 3, and 4 of Examples, pigment Unipure Re LC 3079 (a2) and PPG-3 benzyl ether myristate (a3) ​​were then mixed to form a pre-dispersion. This pre-dispersion was then incorporated into the cream matrix.

[0245] In the final step, aminosiloxane DOWSIL AP-8568 Amino Fluid (a1) is added to all four example formulations 1 to 4.

[0246] 2. Application First, the colorimetry of the hair strand (Kerling Euroaturhaar white) was measured using a Datacolor Spectraflash 450 colorimeter.

[0247] The formulations of Examples 1 to 4 were applied as hair dyes as follows: After preparation, the corresponding reagent was applied to a hair strand (Kerling, Euronatural hair white, liquid ratio: 1 g reagent (E1) / g hair strand). The reagent was left to act for three minutes. Subsequently, the hair strand was thoroughly washed with water (1 minute), dried, and then colorimetric measurements were performed using a Datacolor Spectraflash 450 colorimeter.

[0248] The ΔE value used to assess color intensity is derived from L measured at each hair strand. a b Colorimetric values ​​are shown below: ΔE = [ (L i – L0) 2 + (a i – a0) 2 + (b i – b0)] 1 / 2 L0, a0, and b0 = measurements of the hair strand before dyeing. L i a i and b i =Measurement of hair strands after dyeing The larger the ΔE value, the higher the staining intensity (the better). Ten trained individuals assessed the feel of the dyed hair strands. For hair feel, scores were distributed from 1 to 6 (1: very poor hair feel (rough, brittle, dull), 6: very good hair feel (smooth, soft, neat)).

[0249] The dyed hair strands were also evaluated based on their rubbing fastness. To assess rubbing fastness, the hair strands underwent standardized mechanical abrasion and were then measured again using colorimetry. The ΔE value used to evaluate rubbing fastness was determined by L measured at each section of the hair strand. a b The colorimetric values ​​are as follows: ΔE = [ (L i – L0) 2 + (a i – a0) 2 + (b i – b0)] 1 / 2 L0, a0, and b0 = measurements of the hair strands after dyeing. L i a i and b i =Measurements of hair strands after dyeing and after mechanical stress The larger the ΔE value, the greater the color shift caused by wear, which means the worse the rubbing fastness.

[0250] After dyeing and drying, each hair strand was hand-washed three times. For each wash, the hair strand was wetted, and then a commercially available shampoo (Schwarzkopf, Schauma 7 herbs) was massaged into the strand for 25 seconds (0.25 g 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 hair strand was again measured using a colorimeter.

[0251] The ΔE value used to assess wash fastness is determined by measuring L. a b The colorimetric values ​​are as follows: ΔE = [ (L i – L0) 2 + (a i – a0) 2 + (b i – b0)] 1 / 2 L0, a0, and b0 = measurements of the dyed hair strands before and after washing. L i a i and b i = Measurements of dyed hair strands after 3 shampooing sessions The larger the ΔE value, the greater the color shift caused by washing, meaning the worse the wash fastness.

[0252] The results are as follows:
