Description

[Technical Field]

[0001] The subject of the present application is an agent for coloring keratinous materials, in particular human hair, which contains at least one amino-functionalized silicone polymer (a1), at least one coloring compound (a2) and at least one ester oil (a3).

[0002] A second subject of the present application is a method for dyeing keratinous materials, in particular human hair, in which an agent according to the first subject of the invention is applied to the keratinous materials, allowed to act and then rinsed off again with water. [Background technology]

[0003] Changing the shape and color of keratinous materials, especially human hair, is a key area of ​​modern cosmetics. To change hair color, experts know a variety of coloring systems depending on the coloring requirements. Oxidative dyes are usually used for permanent and solid dyeing, have good fastness properties, and provide good gray coverage. Such colorants usually contain oxidative dye precursors, so-called developer and coupler components, which together form the actual dye under the influence of an oxidizing agent such as hydrogen peroxide. Oxidative dyes are characterized by very long-lasting color results.

[0004] When using direct dyes, the pre-formed dye diffuses from the colorant into the hair fiber. Compared to oxidative dyes, the color obtained with direct dyes is shorter-lasting and washes out quickly. The color of direct dyes typically remains on the hair for 5 to 20 washes.

[0005] It is known that the use of color pigments can cause short-term color changes in hair and / or skin. Color pigments are understood to be insoluble coloring substances. They exist in the form of small particles in the dye formulation in an undissolved state and are merely deposited on the outer surface of hair fibers and / or skin surfaces. Therefore, they can usually be removed without residue by rinsing several times with a detergent containing a surfactant. Various products of this type are available on the market under the name of hair mascara.

[0006] Until now, the use of oxidative dyes has been the only option when users want particularly long-lasting coloring. However, despite numerous optimization attempts, the unpleasant ammonia and amine odors of oxidative hair dyes cannot be completely avoided. In addition, the damage to hair that still accompanies the use of oxidative dyes has a negative effect on the user's hair. Therefore, the ongoing challenge is the research into alternative, high-performance dyeing processes. In particular, the color strength and wash fastness of dyes based on the use of pigments still need to be improved. Summary of the Invention [Problem to be solved by the invention]

[0007] The object of the present invention is to provide a dyeing system that has color strength as comparable as possible to oxidative dyeing.However, the oxidative dye precursors that are usually used for this purpose should not be used.There is a need for a technology that allows previously known coloring compounds (especially pigments) to be fixed to hair in a very durable way.When using the agent in the dyeing process, it should achieve a particularly strong dyeing result with good fastness.In addition, the agent should also have improved gray hair coverage. [Means for solving the problem]

[0008] Surprisingly, it has been found that this problem can be solved excellently when keratinous materials, in particular hair, are colored with an agent containing at least one amino-functionalized silicone polymer (a1), at least one coloring compound (a2) and at least one ester oil (a3).

[0009] A first subject of the invention is an agent for coloring keratinous materials, in particular human hair, comprising: (a1) at least one amino-functionalized silicone polymer, and (a2) at least one coloring compound, and (a3) at least one ester oil; [Effects of the Invention]

[0010] In the course of the research carried out in this invention, it was surprisingly found that the use of ester oils (a3) ​​in agents containing aminosilicones (a1) and coloring compounds (a2) leads to improved color strength when the agents are applied to keratinous materials, in particular human hair, in dyeing processes. These positive effects are observed when the coloring compounds (a2) are pigments. DETAILED DESCRIPTION OF THE INVENTION

[0011] [Keratinous substances] Keratinous materials include hair, skin, nails (e.g., fingernails and / or toenails). Wool, fur, and feathers also fall within the definition of keratinous materials.

[0012] Preferably, keratinous material is understood to mean human hair, human skin and human nails, in particular fingernails and toenails. Keratinous material is understood to be human hair.

[0013] [Coloring Agent] In the context of the present invention, the term "coloring agent" is used to refer to the coloring of keratinous materials, hair coloring, which is caused by means of coloring compounds, in particular pigments, in which the pigments are deposited as coloring compounds on the surface of the keratinous materials in a particularly homogeneous, uniform and smooth film.

[0014] Amino-functionalized silicone polymer (a1) As a first component (a1) essential to the present invention, the agent contains at least one amino-functionalized silicone polymer, which may alternatively be called aminosilicone or amodimethicone.

[0015] Silicone polymers are macromolecules having 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, and comprising repeating organic units.

[0016] The maximum molecular weight of a silicone polymer depends on the degree of polymerization (number of monomers being polymerized) and batch size, and is determined in part by the polymerization method. For purposes of this invention, it is understood that a silicone polymer having a maximum molecular weight of 10 7 g / mol or less, preferably 10 6 g / mol or less, particularly preferably 10 5 It is preferred that it is less than or equal to g / mol.

[0017] Silicone polymers contain many Si-O repeating units, and the Si atoms may carry organic residues, such as alkyl or substituted alkyl groups. Silicone polymers are therefore alternatively referred to as polydimethylsiloxanes.

[0018] The silicone polymer is based on more than 10 Si-O repeat units, preferably more than 50 Si-O repeat units, more preferably more than 100 Si-O repeat units, and most preferably more than 500 Si-O repeat units, corresponding to a high molecular weight.

[0019] Amino-functionalized silicone polymer is understood to mean the functionalized silicone that has at least one structural unit with amino group.Preferably, amino-functionalized silicone polymer has a plurality of structural units, each of which has at least one amino group.Amino group is understood to mean primary amino group, secondary amino group and tertiary amino group.All of these amino groups can be protonated under acidic environment and exist in their cationic form.

[0020] In principle, when the amino-functionalized silicone polymer (a1) has at least one primary, at least one secondary and / or at least one tertiary amino group, the amino-functionalized silicone polymer (a1) can be used to obtain advantageous effects.However, the dyeing with the highest washing fastness is found when the amino-functionalized silicone polymer (a1) that contains at least one secondary amino group is used in the agent.

[0026] Divalent C 1- C 20 The alkylene group may alternatively be a divalent or divalent C 1- C 20 They may be referred to as alkylene groups, which means that each ALK1 or AK2 group can form two bonds.

[0027] In the case of ALK1, one bond arises from the silicon atom to the ALK1 group, and the second bond is between ALK1 and the secondary amino group.

[0028] 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.

[0029] Linear divalent C 1- C 20Examples of alkylene groups include methylene (-CH-), ethylene (-CH-CH-), propylene (-CH-CH-CH-), and butylene (-CH-CH-CH-CH-). The propylene group (-CH-CH-CH-) is particularly preferred. From a chain length of 3 C atoms, the divalent alkylene group may also be branched. Branched divalent divalent C 3- C 20 Examples of alkylene groups are (-CH2-CH(CH3)-) and (-CH2-CH(CH3)-CH2-).

The mixture is heated to 25°C for 1 hour while stirring with a magnetic stirrer. If undissolved components of the pigment are still visible in the mixture after this period, the solubility of the pigment is less than 0.5 g / L. If the pigment-water mixture cannot be visually evaluated due to the high intensity of the finely dispersed pigment, the mixture is filtered. If undissolved pigment remains on the filter paper, the solubility of the pigment is less than 0.5 g / L.

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

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

[0064] Preferred color pigments are selected from synthetic or natural inorganic pigments.

[0066] According to the present invention, colored pearlescent pigments are also particularly preferred. They are usually mica and / or mica-based and can be coated with one or more metal oxides. Mica belongs to the layered silicates. The most important representatives of these silicates are muscovite, phlogopite, sodalite, biotite, lepidolite, and margarite. To prepare pearlescent pigments in combination with metal oxides, mica, muscovite, or phlogopite are coated with metal oxides.

[0067] As an alternative to natural mica, synthetic mica coated with one or more metal oxides can also be used as pearlescent pigments.

The particles may be, for example, inorganic substrates. They may be aluminum, silica, calcium borosilicate, calcium aluminum borosilicate, or even aluminum.

[0079] For example, alizarin color varnish can be used.

[0080] Due to their excellent lightfastness and heat resistance, the use of the above pigments in the agent of the present invention is particularly preferred.It is also preferred that the pigments used have a specific particle size.Therefore, according to the present invention, at least one pigment has an average particle size D of 1.0 to 50 μm, preferably 5.0 to 45 μm, preferably 10 to 40 μm, 14 to 30 μm. 50 It is advantageous to have an average particle size D 50 can be determined, for example, using dynamic light scattering (DLS).

[0081] The coloring compound (a2), a colorant compound from the group of pigments, represents the second essential component of the agent according to the invention and is preferably used in the agent in a specific range of amounts.

[0082] Particularly satisfactory results have been obtained when the agent according to the invention contains one or more pigments (a2) in a total amount of 0.01 to 10.0% by weight, preferably 0.1 to 5.0% by weight, more preferably 0.2 to 2.5% by weight, and very preferably 0.25 to 1.5% by weight, based on the total weight of the agent.

[0083] In another very particularly preferred embodiment, the agent according to the invention is characterized in that it contains one or more pigments (a2) in a total amount of 0.01 to 10.0% by weight, preferably 0.1 to 5.0% by weight, more preferably 0.2 to 2.5% by weight, and very particularly preferably 0.25 to 1.5% by weight, based on the total weight of the agent.

[0084] As the coloring compound (a2), the agent according to the present invention may also contain one or more direct dyes. Direct dyes are dyes that are absorbed directly into hair and do not require an oxidation process to form color. Direct dyes are usually nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinones, triarylmethane dyes, or indophenols.

[0085] Direct dyes within the meaning of the present invention have a solubility in water (760 mmHg) of more than 0.5 g / L at 25° C. and therefore should not be considered as pigments.

[0086] Preferably, direct dyes within the meaning of the present invention have a solubility in water (760 mmHg) of more than 1.0 g / L at 25°C.

[0087] Direct dyes can be divided into anionic, cationic, and nonionic direct dyes.

[0088] In a further embodiment, the agent according to the invention is characterized in that it comprises at least one coloring compound (a2) from the group consisting of anionic, nonionic and cationic direct dyes.

[0089] 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 (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 and Basic Red 76.

[0090] As nonionic direct dyes, nonionic nitro and quinone dyes as well as neutral azo dyes can be used. Suitable nonionic direct dyes are those described 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, as well as known compounds such as 1,4-diamino-2-nitrobenzene, 2-amino-4-nitrophenol, 1,4-bis-(2-hydroxyethyl)-amino-2-nitrobenzene, and 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, picramic acid and its salts, 2-amino-6-chloro-4-nitrophenol, 4-ethylamino-3-nitrobenzoic acid, and 2-chloro-6-ethylamino-4-nitrophenol.

[0091] Anionic direct dyes are also called acid dyes. Acid dyes are direct dyes that have at least one carboxylic acid group (-COOH) and / or one sulfonic acid group (-SO3H). Depending on the pH value, the protonated forms of the carboxylic acid or sulfonic acid groups (-COOH, -SO3H) can be converted to their deprotonated forms (-COO - , -SO3 -The proportion of the protonated form increases with decreasing pH. When direct dyes are used in the form of their salts, the carboxylic acid or sulfonic acid group is present in the deprotonated form and is neutralized with a corresponding stoichiometric equivalent of a cation to maintain electrical neutrality. The acid dyes of the present invention can also be used in the form of their sodium salts and / or their potassium salts.

[0092] Acid dyes within the meaning of the present invention have a solubility in water (760 mmHg) of more than 0.5 g / L at 25° C. and therefore should not be considered pigments. Preferably, acid dyes within the meaning of the present invention have a solubility in water (760 mmHg) of more than 1.0 g / L at 25° C.

[0093] Alkaline earth salts (such as calcium and magnesium salts) or aluminum salts of acid dyes often have lower solubilities than the corresponding alkali salts. If the solubility of these salts is less than 0.5 g / L (25°C, 760 mmHg), they do not fall within the definition of direct dyes.

[0094] An essential feature of acid dyes is their ability to form an anionic charge, whereby the carboxylic or sulfonic acid group involved is usually attached to a different chromophore system. Suitable chromophore 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.

[0095] In a further embodiment, the agent for dyeing keratinous materials is characterized in that it comprises at least one anionic direct dye selected from the group consisting of nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinone dyes, triarylmethane dyes, xanthene dyes, rhodamine dyes, oxazine dyes and / or indophenol dyes, wherein the dyes from the above group each have 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).

[0097] For example, the water solubility of an anionic direct dye can be determined as follows: 0.1 g of anionic direct dye is placed in a beaker. A stirring bar is added. 100 mL of water is then added. The mixture is heated to 25°C while stirring magnetically. This mixture is stirred for 60 minutes. The aqueous mixture is then visually evaluated. If there is still undissolved residue, the amount of water is increased, for example, in 10 mL increments. Water is added until the amount of dye used is completely dissolved. If the dye strength is too high to visually evaluate the dye-water mixture, the mixture is filtered. If undissolved dye remains on the filter paper, the solubility test is repeated 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.

[0098] 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.).

[0101] 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 highly soluble in water at 25°C.

[0102] Acid Orange 7 is the sodium salt of 4-[(2-hydroxy-1-naphthyl)azo]benzenesulfonate. Its water solubility is greater than 7 g / L at 25°C.

[0103] Acid Red 18 is the trinalium salt of 7-hydroxy-8-[(E)-(4-sulfonato-1-naphthyl)-diazenyl)]-1,3-naphthalenedisulfonate and has very high water solubility of more than 20% by weight.

[0104] Acid Red 33 is the dianthrlium salt of 5-amino-4-hydroxy-3-(phenylazo)-naphthalene-2,7-disulfonate, and its solubility in water is 2.5 g / L (25° C.).

[0105] Acid Red 92 is the disodium salt of 3,4,5,6-tetrachloro-2-(1,4,5,8-tetrabromo-6-hydroxy-3-oxoxanthen-9-yl)benzoic acid, and its solubility in water is shown to be greater than 10 g / L (25° C.).

Sugar tensides of the alkyl and alkenyl oligoglucoside type are prepared by the methods described above. They can be obtained by the relevant methods of preparative organic chemistry. Alkyl and alkenyl oligoglycosides can be derived from aldoses or ketoses having 5 or 6 carbon atoms, preferably glucose. Therefore, preferred alkyl and / or alkenyl oligoglycosides are alkyl and / or alkenyl oligoglucosides. The index number p in the general formula (Tnio-2) indicates the degree of oligomerization (DP), i.e., the distribution of monoglycosides and oligoglycosides, and is a number between 1 and 10. p must always be an integer within each molecule and can take values ​​from 1 to 6. However, the value p for a given alkyl oligoglycoside is an analytically determined arithmetic quantity, which is usually expressed as a fraction. Preferably, alkyl and / or alkenyl oligoglycosides with an average degree of oligomerization p of 1.1 to 3.0 are used.

Hydrogenated C with a DP of 1-3 12 / 14 Palm alcohol-based alkyl oligoglucosides are preferred. Sugar surfactants of fatty acid N-alkyl polyhydroxyalkylamide type, nonionic surfactants of formula (Tnio-3), [ka] In the formula, R 5 CO is an aliphatic acyl group containing 6 to 22 carbon atoms, and R 6 where [Z] is hydrogen, an alkyl group or a hydroxyalkyl group containing 1 to 4 carbon atoms, and [Z] is a linear or branched polyhydroxyalkyl group containing 3 to 12 carbon atoms and 3 to 10 hydroxyl groups. Fatty acid N-alkyl polyhydroxyalkylamides are known substances that are typically obtained by reductive amination of reducing sugars with ammonia, alkylamines or alkanolamines, followed by acylation with fatty acids, fatty acid alkyl esters or fatty acid chlorides. Fatty acid N-alkyl polyhydroxyalkylamides are preferably derived from reducing sugars having 5 or 6 carbon atoms, especially glucose. Thus, preferred fatty acid N-alkyl polyhydroxyalkylamides are those of the formula (Tnio-4): [ka] The fatty acid N-alkyl glucamides are represented by the formula: Preferably, the glucamide of formula (Tnio-4) is used as a fatty acid-N-alkyl polyhydroxyalkylamide, where R represents hydrogen or an alkyl group, and R 7 CO represents the acyl residue of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, arachidic acid, gadoleic acid, behenic acid, or erucic acid, or a technical mixture thereof.

[0168] Other typical examples of nonionic surfactants are fatty acid amide polyglycol ethers, fatty amine polyglycol ethers, mixed ethers or mixed formals, protein hydrolysates (especially wheat-based vegetable products) and polysorbates.

[0169] Alkylene oxide addition products to saturated linear fatty alcohols and fatty acids, each containing 2 to 30 moles of ethylene oxide per mole of fatty alcohol or fatty acid, as well as sugar surfactants, have proven to be preferred nonionic surfactants. Preparations with excellent properties are also obtained when fatty acid esters of ethoxylated glycerol are included as nonionic surfactants.

[0170] These bonds are distinguished by the following parameters: The alkyl group R contains 6 to 22 carbon atoms and can be either linear or branched. Primary linear and 2-methyl-branched aliphatic groups are preferred. Such alkyl groups are, for example, 1-octyl, 1-decyl, 1-lauryl, 1-myristyl, 1-cytyl, and 1-stearyl. 1-octyl, 1-decyl, 1-lauryl, and 1-myristyl are particularly preferred. When so-called "oxo alcohols" are used as starting materials, compounds with an odd number of carbon atoms in the alkyl chain predominate.

[0171] The alkyl group-containing compounds used as surfactants can be homogeneous substances, but in the production of these substances it is usually preferable to start from natural plant or animal raw materials so that a mixture of substances with different alkyl chain lengths is obtained depending on the respective raw materials.

[0172] For surfactants that are the addition products of ethylene and / or propylene oxide to fatty alcohols or derivatives of these addition products, both products with "normal" homolog distribution and products with narrow homolog distribution can be used. "Normal" homolog distribution refers to the mixture of homologs obtained by the reaction of fatty alcohols with alkylene oxides using alkali metals, alkali metal hydroxides, or alkali metal alcoholates as catalysts. On the other hand, for example, when using hydrotalcite, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides, or alcoholates as catalysts, narrowed homolog distributions can be obtained. In some cases, it is preferable to use products with narrow homolog distributions.

[0176] Nonionic surfactants, particularly nonionic surfactants of formula (TI), are preferably used in agent (b) in an appropriate amount range.

It is characterized by:

[0194] In addition to the above-mentioned nonionic surfactants, the agent can also contain one or more charged surfactants in principle. The term surfactant refers to a surface-active substance. A distinction is made between anionic surfactants, which consist of a hydrophobic group and a negatively charged hydrophilic head group; amphoteric surfactants, which have both a negative charge and a compensating positive charge; cationic surfactants, which have a hydrophobic group and a positively charged hydrophilic group; and nonionic surfactants, which have no charge but have a strong dipole moment and are strongly hydrated in aqueous solution.

[0195] Zwitterionic surfactants contain at least one quaternary ammonium group and at least one -COO group in the molecule. (-) -or-SO3 (-) These are surface-active compounds having a hydroxyl group. Particularly suitable zwitterionic surfactants are N-alkyl-N,N-dimethylammonium glycinates, such as cocoalkyl-dimethylammonium glycinate, N-acylaminopropyl-N,N-dimethylammonium glycinates, such as cocoacylaminopropyldimethylammonium glycinate, and so-called betaines, such as 2-alkyl-3-carboxymethyl-3-hydroxyethylimidazolines, each having 8 to 18 carbon atoms in the alkyl or acyl group, and cocoacylaminoethylhydroxyethylcarboxymethylglycinate.
