Description

Technical Field

[0001] The present application relates to the field of cosmetics and to a method for treating keratinous materials, in particular human hair, which comprises the use of two compositions (A) and (B). Composition (A) is a low-moisture preparation comprising at least one C1-C6 organic alkoxysilane, and composition (B) comprises, in addition to water, at least one aromatic or aliphatic aldehyde having from 2 to 20 carbon atoms.

[0002] A second object of the present invention is a multi-component packaging unit (kit-of-parts) for dyeing keratinous materials, comprising the above two compositions (A) and (B) separately packaged in two packaging units.

Background Art

[0003] Changing the shape and color of keratin fibers, especially hair, is an important area of today's cosmetics. To change hair color, experts know various dyeing systems depending on the coloring requirements. Oxidation dyes are usually used for permanent and strong dyeing with good fastness and good gray hair coverage. Such dyes usually contain precursors of oxidation dyes, so-called developing components and coloring components, which form the actual dye with each other under the influence of an oxidizing agent such as hydrogen peroxide. Oxidation dyes are characterized by a very long-lasting dye finish.

[0004] When using direct dyes, the ready-made dye diffuses from the colorant into the hair fibers. Compared to oxidative hair dyes, the dyeings obtained with direct dyes have a shorter color retention period and are washed out more quickly. Dyeing with direct dyes usually remains on the hair over 5 to 20 shampoos.

[0005] The use of coloring pigments is known for short-term changing of the color of hair and / or skin. Coloring pigments are understood as insoluble coloring substances. These coloring pigments are present in the dye preparation in the form of small particles in an undissolved state and merely deposit from the outside onto the hair fibers and / or the skin surface. Therefore, they can usually be removed again without residue by washing several times with a surfactant-containing detergent. Various products of this type are available on the market under the name of hair mascara.

[0006] European Patent No. 2168633 addresses the problem of producing a long-lasting hair dye using pigments. This document teaches that when a combination of a pigment, an organosilicon compound, a hydrophobic polymer, and a solvent is used on hair, it is possible to provide a coloring that is particularly resistant to shampooing.

[0007] The organosilicon compounds used in European Patent No. 2168633 are reactive compounds of the alkoxysilane type. These alkoxysilanes hydrolyze rapidly in the presence of water and form hydrolysis products and / or condensation products depending on the amounts of alkoxysilane and water used in each case. The influence exerted by the amount of water used in this reaction on the properties of the hydrolysis products or condensation products is described, for example, in International Publication No. 2013 / 068979.

[0008] When these alkoxysilanes or their hydrolysis or condensation products are applied to a keratinous material, a film or coating is formed on the keratinous material, completely encapsulating the keratinous material and thereby strongly influencing the properties of the keratinous material. Areas of application include permanent styling or permanent shape modification of keratin fibers. In this method, the keratin fibers are mechanically shaped into the desired shape and then fixed in this shape by forming the above coating. Another particularly preferred application of the present invention is the coloring of keratinous materials, where the coating or film is formed in the presence of a coloring compound, such as a pigment. The film colored with the pigment remains on the keratinous material or keratin fibers, resulting in a surprisingly wash-resistant coloring.

[0009] A major advantage of the alkoxysilane-based dyeing principle is that the high reactivity of this class of compounds enables very rapid coating. This means that extremely good coloring results can be achieved with a significantly short application time of just a few minutes. However, in addition to these advantages, the high reactivity of alkoxysilanes also has some drawbacks.

[0010] Due to its high reactivity, an organic alkoxysilane cannot be prepared together with a large amount of water. The reason is that excess water immediately initiates hydrolysis and subsequent polymerization. The polymerization that occurs during the storage of alkoxysilanes in an aqueous medium appears as thickening or gelling of the aqueous preparation. As a result, the preparation becomes very highly viscous and gels or becomes gel-like, and can no longer be applied evenly to the keratinous material. Furthermore, the storage of alkoxysilanes in the presence of an excess amount of water is accompanied by the loss of its reactivity, and as a result, the formation of a resistant coating on the keratinous material is no longer possible.

[0011] For these reasons, it is necessary to store the organic alkoxysilane in an anhydrous or low-moisture environment and prepare the corresponding preparation in a separate container. Since alkoxysilane is highly reactive, it can react not only with water but also with other cosmetic components. Therefore, in order to avoid all unwanted reactions, the preparation containing alkoxysilane preferably contains no other components or only selected components that have been found to be chemically inert to alkoxysilane. Therefore, it is preferably selected such that the concentration of alkoxysilane in the preparation is high. A low-moisture preparation containing alkoxysilane at a relatively high concentration is sometimes called a "silane blend".

[0012] When applying to a keratinous material, the current user must convert this high-concentration silane blend into a ready-to-use mixture. In this ready-to-use mixture, on the one hand, the concentration of the organic alkoxysilane decreases, and on the other hand, the coating mixture contains a higher proportion of water (or alternative components) that induces the polymerization that results in the coating.

[0013] It has been found that optimally adapting the polymerization rate, i.e., the rate at which the coating is formed on the keratinous material, to the application conditions is an extremely challenging task.

[0014] For example, when applying to human hair, if the polymerization rate is too fast, the polymerization will be completed before all hair parts are treated. Therefore, if the polymerization is too fast, it becomes impossible to treat the entire head. In the coloring process, too-fast polymerization results in an extremely non-uniform color, so that the last-treated hair parts are only inadequately colored.

[0015] On the other hand, if the polymerization is too slow, the entire range of the hair can be treated without time constraints, but this lengthens the application time or the time of exposing the preparation to the keratinous material. Therefore, if the polymerization is too slow, the great advantage of this dyeing technique of forming a wash-fast color with the shortest application time is not effective.

Summary of the Invention

Problems to be Solved by the Invention

[0017] The object of the present application was to find a method for treating keratinous substances that can adapt the rate of polymerization of organic alkoxysilanes to the use conditions, particularly to the general conditions when applying to the human head. In other words, there has been a need for a method that can maintain the reactivity of the organic alkoxysilane long enough to enable treatment of the entire head without unduly prolonging the application time.

Means for Solving the Problems

[0018] Surprisingly, it has been found that this problem can be completely solved by a method of treating a keratinous substance by applying two compositions (A) and (B) to the keratinous substance. The first composition (A) is the aforementioned low-moisture silane blend. The second composition (B) is water-containing and contains at least one aromatic or aliphatic aldehyde having 2 to 20 carbon atoms. During application, the compositions (A) and (B) come into contact with each other, and this contact can be effected by pre-mixing (A) and (B), or by successive application of (A) and (B) to the keratinous substance.

[0019] A first object of the present invention is a method for treating keratinous substances, particularly human hair, the method comprising: · A first composition (A), based on the total weight of said composition (A), (A1) less than 10% by weight of water, and (A2) one or more organic C1-C6 alkoxysilanes and / or their condensation products A composition comprising: A second composition (B), (B1) water, and (B2) One or more aromatic or aliphatic aldehydes having 2 to 20 carbon atoms A composition comprising is applied to the keratinous material.

[0020] It has been shown that the aldehyde (B2) contained in the water-containing composition (B) reduces the polymerization rate of the organic C1-C6 alkoxysilane (A2) when in contact with the composition (A). Surprisingly, the reactivity of the organic C1-C6 alkoxysilane (A2) could be optimally adapted to the application conditions prevailing in the total head coloring method. Even more complex and time-consuming dyeing techniques, such as the dyeing of specially arranged highlights on the head, could be realized by using the method according to the invention. When the two compositions (A) and (B) were used in the dyeing method for the keratinous material of human hair, dyeings with particularly high uniformity, fastness and washfastness were possible with this method. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] <Treatment of keratinous materials> Keratinous materials include hair, skin, nails (such as fingernails and / or toenails), etc. Additionally, wool, fur, and feathers are also included within the definition of keratinous materials.

[0022] Preferably, keratinous materials are understood to be human hair, human skin and human nails, in particular fingernails and toenails. Keratinous materials are understood to be human hair.

[0023] An agent for treating keratin substances is understood to mean, for example, an agent for coloring keratin substances, an agent for reforming or shaping keratin substances, especially keratin fibers, or an agent for conditioning or caring for keratin substances. The agent prepared by the method according to the invention is particularly suitable for coloring keratin substances, especially preferably keratin fibers which are human hair.

[0024] The term "coloring agent" is used in the context of the present invention to refer to the coloring of the keratin substance of the hair which results from the use of coloring compounds such as pigments, mica, direct dyes, thermochromic and photochromic dyes and / or oxidation dyes. The use of pigments is particularly preferred. In this dyeing process, the coloring compound deposits on the surface of the keratin substance in a particularly homogeneous and smooth film or diffuses into the keratin fibers. The film is formed in situ by the oligomerization or polymerization of an organic alkoxysilane or by the interaction of the coloring-imparting compound with other components such as organic silicon compounds and optionally film-forming polymers.

[0025] <(Moisture content (A1) in composition (A))> The method according to the invention is characterized in that a first composition (A) is applied to the keratin substance.

[0026] In order to ensure a sufficiently high storage stability, composition (A) is characterized by low moisture, preferably being substantially free of water. Accordingly, composition (A) contains less than 10% by weight of water based on the total weight of composition (A).

[0027] With a water content of less than 10% by weight, composition (A) is stable during long-term storage. However, in order to further improve storage stability and ensure a sufficiently high reactivity of the organic C1-C6 alkoxysilane (A2), it has been found that it is particularly preferable to further reduce the water content in composition (A). For this reason, the first composition (A) preferably contains 0.01 to 9.5% by weight, more preferably 0.01 to 8.0% by weight, still more preferably 0.01 to 6.0% by weight, and particularly preferably 0.01 to 4.0% by weight of water (A1) based on the total weight of composition (A).

[0028] In a particularly preferred embodiment, the method according to the invention is characterized in that the first composition (A) contains 0.01 to 9.5% by weight, preferably 0.01 to 8.0% by weight, more preferably 0.01 to 6.0% by weight, and particularly preferably 0.01 to 4.0% by weight of water (A1) relative to the total weight of composition (A).

[0029] <Organic C1-C6 alkoxysilane (A2) and / or its condensation product in composition (A)> Composition (A) is characterized by containing one or more organic C1-C6 alkoxysilanes (A2) and / or its condensation product.

[0030] The organic C1-C6 alkoxysilane is an organic non-polymeric silicon compound and is preferably selected from the group of silanes containing 1, 2 or 3 silicon atoms.

[0031] The organic silicon compound is also called an organosilicon compound and is a compound having a direct silicon-carbon bond (Si-C) or in which carbon is bonded to a silicon atom via an oxygen, nitrogen or sulfur atom. The organic silicon compound of the present invention is preferably a compound containing 1 to 3 silicon atoms. The organic silicon compound is preferably a compound containing 1 or 2 silicon atoms.

[0032] According to the IUPAC rules, the term silane means a chemical compound based on a silicon skeleton and hydrogen. In organosilanes, the hydrogen atoms are completely or partially replaced by organic groups such as (substituted) alkyl groups and / or alkoxy groups.

[0033] The C1-C6 alkoxysilanes according to the invention are characterized in that at least one C1-C6 alkoxy group is directly bonded to the silicon atom. Thus, the C1-C6 alkoxysilanes according to the invention contain at least one structural unit R'R''R'''Si-O-(C1-C6 alkyl), where the radicals R', R'' and R''' represent the three remaining valence bonds of the silicon atom.

[0034] One or more C1-C6 alkoxy groups bonded to the silicon atom are highly reactive and are hydrolyzed rapidly in the presence of water, and the reaction rate depends, inter alia, on the number of hydrolyzable groups per molecule. When the hydrolyzable C1-C6 alkoxy group is an ethoxy group, the organosilicon compound preferably contains the structural unit R'R''R'''Si-O-CH2-CH3. The residues R', R'' and R''' also represent here the three remaining free valences of the silicon atom.

[0035] Even the addition of a small amount of water causes hydrolysis first, followed by a condensation reaction between the organic alkoxysilanes. For this reason, both the organic alkoxysilane (A2) and its condensation product can be present in the composition.

[0036] The condensation product is understood to be a product formed by the reaction of at least two organic C1-C6 alkoxysilanes with elimination of water and / or elimination of C1-C6 alkanol.

[0037] For example, the condensation product may be not only a dimer but also a trimer or an oligomer, and the condensation product is always in equilibrium with the monomer.

[0038] Depending on the amount of water used or consumed in hydrolysis, the equilibrium shifts from monomeric C1-C6 alkoxysilanes to the condensation product.

[0039] In a particularly preferred embodiment, the process according to the invention is characterized in that the composition (A) comprises at least one organic C1-C6 alkoxysilane (A2) selected from silanes having 1, 2 or 3 silicon atoms, and the organosilicon compound further comprises at least one basic chemical functional group.

[0040] This basic group can be, for example, an amino group, an alkylamino group or a dialkylamino group, and is preferably bonded to the silicon atom via a linker. Preferably, the basic group is an amino group, a C1-C6 alkylamino group or a di(C1-C6)alkylamino group.

[0041] A particularly preferred process according to the invention is characterized in that the composition (A) comprises at least one organic C1-C6 alkoxysilane (A2) selected from the group of silanes having 1, 2 or 3 silicon atoms, and the C1-C6 alkoxysilane further comprises at least one basic chemical functional group.

[0042] In the process according to the invention, particularly satisfactory results were obtained when using C1-C6 alkoxysilanes of formula (S-I) and / or (S-II). As mentioned above, hydrolysis / condensation starts with only a small amount of moisture, so the condensation products of C1-C6 alkoxysilanes of formula (S-I) and / or (S-II) are also included in this aspect.

[0043] In another very particularly preferred embodiment, the process according to the invention is such that the first composition (A) is of formula (S-I) and / or (S-II): Formula (S-I):

[0087] In another preferred embodiment, in the method according to the present invention, composition (A) is · 3-(Trimethoxysilyl)-N-[3-(trimethoxysilyl)propyl]-1-propanamine, · 3-(Triethoxysilyl)-N-[3-(triethoxysilyl)propyl]-1-propanamine, · N-Methyl-3-(trimethoxysilyl)-N-[3-(trimethoxysilyl)propyl]-1-propanamine, · N-Methyl-3-(triethoxysilyl)-N-[3-(triethoxysilyl)propyl]-1-propanamine, · 2-[Bis[3-(trimethoxysilyl)propyl]amino]-ethanol, · 2-[Bis[3-(triethoxysilyl)propyl]amino]ethanol, · 3-(Trimethoxysilyl)-N,N-bis[3-(trimethoxysilyl)propyl]-1-propanamine, · 3-(Triethoxysilyl)-N,N-bis[3-(triethoxysilyl)propyl]-1-propanamine, · N1,N1-Bis[3-(trimethoxysilyl)propyl]-1,2-ethanediamine, · N1,N1-Bis[3-(triethoxysilyl)propyl]-1,2-ethanediamine, · N,N-Bis[3-(trimethoxysilyl)propyl]-2-propen-1-amine and / or · N,N-Bis[3-(triethoxysilyl)propyl]-2-propen-1-amine characterized by comprising one or more organic C1-C6 alkoxysilanes represented by formula (S-II) selected from the group consisting of and / or their condensation products.

[0088] In a further dyeing test, it has also been found to be particularly advantageous when at least one organic C1-C6 alkoxysilane (A2) represented by formula (S-IV):

Chemical formula

[0089] The compound of formula (S-IV) is an organosilicon compound selected from silanes having 1, 2 or 3 silicon atoms, and the organosilicon compound contains one or more hydrolyzable groups per molecule.

Chemical formula

[0091] In a further aspect, a particularly preferred method according to the present invention is that the first composition (A) has the formula (S-IV):

Chemical formula

[0092] In the organic C1-C6 alkoxysilane of formula (S-IV), the R9 group represents a C1-C 12 alkyl group. This C1-C 12The alkyl group is saturated and may be linear or branched. Preferably, R9 represents a linear C1-C8 alkyl group. Preferably, R9 represents a methyl group, an ethyl group, an n-propyl group, an n-butyl group, an n-pentyl group, an n-hexyl group, an n-octyl group, or an n-dodecyl group. Particularly preferably, R9 represents a methyl group, an ethyl group or an n-octyl group.

[0093] In the organosilicon compound of formula (S-IV), the group R 10 represents a C1-C6 alkyl group. Particularly preferably, R 10 represents a methyl group or an ethyl group.

[0094] In the organosilicon compound of formula (S-IV), the group R 11 represents a C1-C6 alkyl group. Particularly preferably, R 11 represents a methyl group or an ethyl group.

[0095] Furthermore, k represents an integer from 1 to 3, and m represents an integer of 3 - k. When k represents the number 3, m is equal to 0. When k represents the number 2, m is equal to 1. When k represents the number 1, m is equal to 2.

[0096] When the composition (A) contains at least one organic C1-C6 alkoxysilane (A2) of formula (S-IV) in which k of the residue represents the number 3, the best washing-fast dyeing was obtained. In this case, the remaining m represents the number 0.

[0098] In a further preferred embodiment, in the method according to the invention, the first composition (A) is · Methyltrimethoxysilane · Methyltriethoxysilane · Ethyltrimethoxysilane · Ethyltriethoxysilane · Hexyltrimethoxysilane · Hexyltriethoxysilane · Octyltrimethoxysilane · Octyltriethoxysilane · Dodecyltrimethoxysilane · Dodecyltriethoxysilane characterized by comprising at least one C1-C6 organic alkoxysilane (A2) of formula (S-IV) selected from the group consisting of and / or their condensation products.

[0099] The corresponding hydrolysis products or condensation products are, for example, the following compounds. Hydrolysis of a C1-C6 alkoxysilane of formula (S-I) with water (reaction scheme using 3-aminopropyltriethoxysilane as an example):

[0100] The condensation reaction is, for example, as follows (shown by a mixture of ((3-aminopropyl)triethoxysilane and methyltrimethoxysilane)). [Chem.] and / or [Chem.] and / or [Chem.] and / or [Chem.] and / or [Chem.] and / or [Chem.] and / or [Chem.]

[0101] In the above exemplary reaction schemes, in each case, condensation to a dimer is shown, but further condensation to oligomers having several silane atoms is also possible and preferred.

[0102] In these condensation reactions, both partially hydrolyzed and fully hydrolyzed C1-C6-alkoxysilanes of the formula (S-I) can be involved, and the unreacted C1-C6-alkoxysilane of the formula (S-I) can also condense with either the partially hydrolyzed or the fully hydrolyzed one. In this case, the C1-C6-alkoxysilane of the formula (S-I) reacts with itself.

[0103] Furthermore, both partially hydrolyzed and fully hydrolyzed C1-C6-alkoxysilanes of the formula (S-I) can be involved in the condensation reaction, and they can condense with the unreacted, or partially or fully hydrolyzed C1-C6-alkoxysilane of the formula (S-IV). In this case, the C1-C6-alkoxysilane of the formula (S-I) reacts with the C1-C6-alkoxysilane of the formula (S-IV).

[0104] Furthermore, both partially hydrolyzed and fully hydrolyzed C1-C6-alkoxysilanes of the formula (S-IV) can be involved in the condensation reaction, and they can condense with the unreacted, or partially or fully hydrolyzed C1-C6-alkoxysilane of the formula (S-IV). In this case, the C1-C6-alkoxysilane of the formula (S-IV) reacts with itself.

[0105] The composition (A) according to the invention can contain one or more organic C1-C6-alkoxysilanes (A2) in various proportions. A person skilled in the art will determine this depending on the desired thickness of the silane coating on the keratinous material and the amount of the keratinous material to be treated.

[0106] When the composition (A) contains one or more organic C1-C6-alkoxysilanes (A2) and / or their condensation products in a total amount of 30.0 to 85.0% by weight, preferably 35.0 to 80.0% by weight, more preferably 40.0 to 75.0% by weight, even more preferably 45.0 to 70.0% by weight, and most preferably 50.0 to 65.0% by weight, based on its total weight, particularly good dyeing results during use and particularly storage-stable preparations could be obtained.

[0107] In a further aspect, a highly particularly preferred method is that the first composition (A) contains one or more organic C1-C6 alkoxysilanes (A2) and / or their condensation products in a total amount of 30.0 to 85.0% by weight, preferably 35.0 to 80.0% by weight, more preferably 40.0 to 75.0% by weight, even more preferably 45.0 to 70.0% by weight, most preferably 50.0 to 65.0% by weight, based on the total weight of the composition (A).

[0108] <Other cosmetic ingredients in composition (A)> In principle, composition (A) may also contain one or more other cosmetic ingredients.

[0109] The cosmetic ingredients that can optionally be used in composition (A) can be any suitable ingredients for imparting further beneficial properties to the product. For example, in composition (A), there can be a solvent, a thickening or film-forming polymer, a surfactant compound from the group of nonionic, cationic, anionic or zwitterionic / amphoteric surfactants, a pigment, a direct dye, a coloring compound from the group of oxidation dye precursors, C8-C 30 fatty alcohols, hydrocarbon compounds, fatty components from the group of fatty acid esters, acids and bases belonging to the group of pH adjusters, fragrances, preservatives, plant extracts and protein hydrolysates.

[0110] The selection of these other substances is made by those skilled in the art according to the desired properties of the agent. For other optional ingredients and their amounts used, explicit reference is made to the relevant manuals known to those skilled in the art.

[0111] However, as described above, the organic C1-C6 alkoxysilane (A2) can react not only with water but also with other cosmetic ingredients. Therefore, in order to avoid these undesirable reactions, the preparation (A) containing alkoxysilane preferably contains no other ingredients or only selected ingredients that are known to be chemically inert to C1-C6 alkoxysilane. In this regard, it has been found that in the composition (A), it is particularly preferred to use cosmetic ingredients selected from the group consisting of hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane and / or decamethylcyclopentasiloxane.

[0112] In another highly preferred embodiment, the method according to the invention is characterized in that the first composition (A) contains at least one cosmetic ingredient selected from the group consisting of hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane.

[0113] Hexamethyldisiloxane has the CAS number 107-46-0 and can be commercially purchased, for example, from Sigma-Aldrich.

Chem.

[0114] Octamethyltrisiloxane has the CAS number 107-51-7 and is also commercially available from Sigma-Aldrich.

Chem.

[0115] Decamethyltetrasiloxane has the CAS number 141-62-8 and is also commercially available from Sigma-Aldrich.

Chem.

[0116] Hexamethylcyclotrisiloxane has the CAS number 541-05-9.

[0117] Octamethylcyclotetrasiloxane has the CAS number 556-67-2.

[0118] Decamethylcyclopentasiloxane has the CAS number 541-02-6.

[0119] It has been found that the use of hexamethyldisiloxane in the composition (A) is particularly preferred. Particularly preferably, hexamethyldisiloxane is present in the composition (A) in an amount of 10.0 to 50.0% by weight, preferably 15.0 to 45.0% by weight, more preferably 20.0 to 40.0% by weight, even more preferably 25.0 to 35.0% by weight, and most preferably 31.0 to 34.0% by weight, based on the total weight of the composition (A).

[0120] In a further very particularly preferred embodiment, the device according to the invention is characterized in that the first composition (A) contains hexamethyldisiloxane in an amount of 10.0 to 50.0% by weight, preferably 15.0 to 45.0% by weight, more preferably 20.0 to 40.0% by weight, even more preferably 25.0 to 35.0% by weight, and very particularly preferably 31.0 to 34.0% by weight, based on the total weight of the composition (A).

[0121] <Moisture content (B1) of the composition (B)> The method according to the invention is characterized in that the second composition (B) is applied to a keratinous material, in particular human hair.

[0122] When applied to a keratinous material, compositions (A) and (B) come into contact, and it is particularly preferred that this contact is established by prior mixing of the two compositions (A) and (B). When (A) and (B) are mixed, a ready-to-use keratin treatment agent is obtained. That is, the stable or storable silane blend (A) is converted to its reactive form upon contact with (B). The mixing of compositions (A) and (B) initiates a polymerization reaction derived from alkoxy-silane monomers or alkoxy-silane oligomers, which ultimately results in the formation of a film or coating on the keratinous material.

[0123] The greater the amount of water in contact with the organic C1-C6 alkoxysilane, the greater the degree of the polymerization reaction. For example, when composition (B) contains a large amount of water, the silane condensates of monomers or oligomers already present in the low-moisture composition (A) now polymerize very rapidly to form higher molecular weight or high molecular weight polymers. The high molecular weight silane polymer then forms a film on the keratinous material. For this reason, water (B1) is an essential component of the invention of composition (B).

[0124] The amount of water in composition (B) can help determine the polymerization rate of the C1-C6 organic alkoxysilane (A2) during application. However, when coloring the entire head, in order to ensure a uniform color finish, the polymerization rate, that is, the rate at which the coating is formed, should not be too fast. For this reason, it has been found that it is particularly preferred to select the amount of water in composition (B) not to be too high.

[0125] Particularly uniform coloring over the entire head could be obtained when composition (B) contains 5.0 to 90.0% by weight, preferably 15.0 to 85.0% by weight, more preferably 25.0 to 80.0% by weight, even more preferably 35.0 to 75.0% by weight, and very particularly preferably 45.0 to 70.0% by weight of water (B1) based on the total weight of composition (B).

[0126] In another particularly preferred embodiment, the method according to the invention is characterized in that the second composition (B) contains 5.0 to 90.0% by weight, preferably 15.0 to 85.0% by weight, more preferably 25.0 to 80.0% by weight, even more preferably 35.0 to 75.0% by weight, very particularly preferably 45.0 to 70.0% by weight of water (B1), based on the total weight of the composition (B).

[0127] <Aldehyde (B2) in composition (B)> Composition (B) is further characterized by the content of at least one aromatic or aliphatic aldehyde (B2) having 2 to 20 carbon atoms.

[0128] An aldehyde is an organic compound having at least one aldehyde group -CHO as a functional group. Also, the aldehyde (B2) according to the present invention may have two or more aldehyde groups. In addition to the at least one aldehyde group, the organic compound may have, for example, at least one hydroxy group, at least one C1-C6 alkyl group, at least one C1-C6 alkoxy group, at least one halogen atom selected from the group consisting of fluorine, chlorine and bromine, at least one amino group, at least one di-C1-C6 alkylamino group, at least one carboxy group -COOH or a salt thereof, or other functional groups such as at least one nitro group.

[0129] The aldehyde according to the present invention is composed of 2 to 20 carbon atoms and may be aromatic or aliphatic.

[0130] An aromatic aldehyde contains at least one aromatic ring, which can be 5-membered or most preferably 6-membered. The 5-membered aromatic is preferably heterocyclic. The 6-membered aromatic can be heterocyclic or carbocyclic.

[0131] Thus, aromatic carbocyclic aldehydes typically contain at least 7 carbon atoms (6 rings of the aromatic carbocycle and at least 1 aldehyde group) and up to 20 carbon atoms. As the aromatic carbocycle, the aldehydes of the present invention can include, for example, a benzene ring or a naphthalene ring.

[0132] Aliphatic aldehydes are compounds that do not contain an aromatic ring system. Aliphatic compounds can be based on an alkyl group or an alkyl chain, the chain can be interrupted by heteroatoms, and the entire chain can be unbranched or branched. Similarly, aliphatic compounds can also be cyclic compounds, but do not form an aromatic ring system. For example, a carbocyclic non-aromatic ring can be a cycloalkane ring such as a cyclohexane ring or a cyclopentane ring.

[0133] Surprisingly, it has been found that the use of at least one aromatic or aliphatic aldehyde (B2) having 2 to 20 carbon atoms optimizes the reaction rate of the organic C1-C6 alkoxysilane and enables particularly uniform coloring throughout the head.

[0134] In principle, this optimization of the reaction rate can be achieved with both aromatic and aliphatic aldehydes. However, the best effects were observed when the second composition (B) contained at least one aromatic carbocyclic aldehyde (B2) having 7 to 20 carbon atoms.

[0135] Furthermore, in a very particularly preferred embodiment, the method according to the invention is characterized in that the second composition (B) contains at least one aromatic carbocyclic aldehyde (B2) having 7 to 20 carbon atoms.

[0136] A carbocycle is a cyclic compound that contains only carbon atoms in the ring. Thus, the aromatic carbocyclic aldehyde (B2) of the present invention having 7 to 20 carbon atoms has an aromatic ring, and the ring system itself is composed of only carbon atoms.

[0137] The simplest aromatic carbocyclic aldehyde (B2) is benzaldehyde, but the aromatic ring may particularly preferably have other substituents.

[0138] The aromatic carbocyclic aldehyde (B2) particularly suitable for solving the problems of the present invention is a compound of general formula (A-I).

Chemical formula

[0139] Furthermore, in a very particularly preferred embodiment, the method according to the invention is characterized in that the second composition (B) comprises at least one aromatic carbocyclic aldehyde (B2) of general formula (A-I).

Chemical formula

[0140] In this context, the selection of the residues Ra1, Ra2, Ra3, and Z is such that the resulting aldehyde has 7 to 20 carbon atoms.

[0141] When using certain aldehydes (B2) of general formula (AI), they were particularly excellent in reducing the polymerization rate of organic C1-C6 alkoxysilanes (A2). Therefore, when using these particularly preferred aldehydes (B2), a dyeing characterized by particularly high color strength, uniformity, rubbing fastness, and washing fastness was obtained.

[0142] Very particularly preferred aldehydes of general formula (AI) can be selected from the group consisting of benzaldehyde and its derivatives, naphthaldehyde and its derivatives, cinnamaldehyde and its derivatives.

[0145] By selecting an appropriate amount of aldehyde (B2), a significant influence can be exerted on the film formation rate from C1-C6 alkoxysilane. Therefore, the use of one or more aldehydes (B2) in a specific amount range has proven to be particularly preferred.,

[0146] It is particularly preferred that the second composition (B) contains one or more aromatic or aliphatic aldehydes (B2) having 2 to 20 carbon atoms in a total amount of 0.1 to 50.0% by weight, preferably 0.5 to 10.0% by weight, more preferably 0.7 to 7.0% by weight, and most preferably 1.0 to 4.0% by weight based on the total weight of the composition (B).

[0147] Even more particularly preferably, in the method according to the invention, the second composition (B) contains, based on the total weight of the composition (B), one or more aromatic or aliphatic aldehydes (B2) having 2 to 20 carbon atoms in a total amount of 0.1 to 50.0% by weight, preferably 0.5 to 10.0% by weight, more preferably 0.7 to 7.0% by weight, very particularly preferably 1.0 to 4.0% by weight.

[0148] It is very preferred that the second composition (B) contains, in a total amount of 0.1 to 50.0% by weight, preferably 0.5 to 10.0% by weight, more preferably 0.7 to 7.0% by weight, most preferably 1.0 to 4.0% by weight, based on the total weight of the composition (B), one or more aldehydes (B2) represented by the general formula (A-I).

[0149] When the composition (B) contains vanillin (B2), the best results were obtained with respect to the color strength, wash fastness and rubbing fastness of the dyeing obtained by the method of the invention. Therefore, it is most preferred to use vanillin as the aldehyde (B2).

[0150] Even more particularly preferably, in the method according to the invention, the second composition (B) contains vanillin (B2) in an amount of 0.1 to 50.0% by weight, preferably 0.5 to 10.0% by weight, more preferably 0.7 to 7.0% by weight, very particularly preferably 1.0 to 4.0% by weight, based on the total weight of the composition (B). Vanillin, like the other aldehydes mentioned, can be commercially purchased from common chemical suppliers known to those skilled in the art, such as Sigma-Aldrich, Fluka or Merck. For example, vanillin having the CAS number 121-33-5 is commercially available from Sigma-Aldrich in various container sizes.

[0151] <The fatty component in the composition (B)> To adjust the viscosity or further improve the coating properties, the composition (B) may optionally contain at least one fatty component.

[0152] The fatty component is a hydrophobic substance that can form a micelle system in the presence of water to form an emulsion. Without being bound by this theory, it is believed that C1-C6 alkoxysilane is embedded in this hydrophobic environment or micelle system, either in its monomeric form or optionally in its fused oligomeric form, resulting in a change in the polarity of the environment. Since the fatty component is hydrophobic, the environment of C1-C6 alkoxysilane is also hydrophobized. The polymerization reaction of C1-C6 alkoxysilane that results in a film or coating is presumed to occur at a reduced rate in an environment with reduced polarity.

[0153] In the present invention, the "fatty component" is an organic compound having a solubility in water at room temperature (22 °C) and atmospheric pressure (760 mmHg) of less than 1% by weight, preferably less than 0.1% by weight. The definition of the fatty component clearly includes only uncharged (i.e., non-ionic) compounds. The fatty component has at least one saturated or unsaturated alkyl group having at least 12 C atoms. The molecular weight of the fatty component is at most 5000 g / mol, preferably at most 2500 g / mol, particularly preferably at most 1000 g / mol. The fatty component is neither a polyoxyalkylated compound nor a polyglycerylated compound.

[0154] Very preferably, the fatty component (B2) contained in the composition (B) is C 12 -C 30 fatty alcohol, C 12 -C 30 fatty acid triglyceride, C 12 -C 30 fatty acid monoglyceride, C 12 -C 30 selected from the group consisting of fatty acid diglyceride and / or hydrocarbon.

[0155] In this regard, very preferred fatty components are C 12 -C 30Fatty alcohol, C 12 -C 30 Fatty acid triglyceride, C 12 -C 30 Fatty acid monoglyceride, C 12 -C 30 It is understood that the components are from the group of fatty acid diglycerides and / or hydrocarbons. For the purposes of the present invention, only non-ionic substances are explicitly regarded as fatty components. Charged compounds such as fatty acids and their salts are not regarded as fatty components.

[0156] C 12 -C 30 The fatty alcohol can be a saturated, monounsaturated or polyunsaturated, straight-chain or branched fatty alcohol having 12 to 30 carbon atoms.

[0157] Preferred straight-chain saturated C 12 -C 30 Examples of fatty alcohols are dodecan-1-ol (dodecyl alcohol, lauryl alcohol), tetradecan-1-ol (tetradecyl alcohol, myristyl alcohol), hexadecan-1-ol (hexadecyl alcohol, cetyl alcohol, palmityl alcohol), octadecan-1-ol (octadecyl alcohol, stearyl alcohol), arachyl alcohol (eicosan-1-ol), henicosyl alcohol (heneicosan-1-ol), and / or behenyl alcohol (docosan-1-ol).

[0158] Preferred linear unsaturated fatty alcohols are (9Z)-octadec-9-en-1-ol (oleyl alcohol), (9E)-octadec-9-en-1-ol (elaidyl alcohol), (9Z,12Z)-octadeca-9,12-dien-1-ol (linoleyl alcohol), (9Z,12Z,15Z)-octadeca-9,12,15-trien-1-ol (linolenoyl alcohol), gadoleyl alcohol ((9Z)-eicos-9-en-1-ol), arachidonol ((5Z,8Z,11Z,14Z)-eicosa-5,8,11,14-tetraen-1-ol), erucyl alcohol ((13Z)-docos-13-en-1-ol), and / or brassidyl alcohol (brassidyl alcohol ((13E)-docosen-1-ol).

[0159] Preferred representative branched fatty alcohols are 2-octyldodecanol, 2-hexyldodecanol and / or 2-butyldodecanol.

[0160] By selecting a particularly suitable fatty component, the polarity of the composition (B) can be optimally adjusted, and the polymerization rate of the C1-C6 alkoxysilane can be made to particularly well match the selected coating conditions.

[0161] In this regard, in particular, the use of at least one C 12 -C 30 fatty alcohol (B2) in the composition (B) has been found to create an emulsion system that can particularly well embed the alkoxysilane (A2).

[0162] In one aspect, the second composition (B) is selected from the group consisting of dodecan-1-ol (dodecyl alcohol, lauryl alcohol), tetradecan-1-ol (tetradecyl alcohol, myristyl alcohol), hexadecan-1-ol (hexadecyl alcohol, cetyl alcohol, palmityl alcohol), octadecan-1-ol (octadecyl alcohol, stearyl alcohol), arachyl alcohol (eicosan-1-ol), heneicosyl alcohol (heneicosan-1-ol), behenyl alcohol (docosan-1-ol), (9Z)-octadec-9-en-1-ol (oleyl alcohol), (9E)-octadec-9-en-1-ol (elaidyl alcohol), (9Z,12Z)-octadeca-9,12-dien-1-ol (linoleyl alcohol), (9Z,12Z,15Z)-octadeca-9,12,15-trien-1-ol (linolenoyl alcohol), gadoleyl alcohol ((9Z)-eicos-9-en-1-ol), arachidonic alcohol ((5Z,8Z,11Z,14Z)-eicosa-5,8,11,14-tetraen-1-ol), erucyl alcohol ((13Z)-docos-13-en-1-ol), brassidyl alcohol ((13E)-docosen-1-ol), 2-octyldodecanol, 2-hexyldodecanol, and / or 2-butyldodecanol, one or more C 12 -C 30 Particularly good results were obtained when the fatty alcohol was included.

[0163] In a very particularly preferred aspect, the method according to the invention is characterized in that the second composition (B) comprises one or more C 12 -C 30 fatty alcohol (B2) selected from the group consisting of the following. dodecan-1-ol (dodecyl alcohol, lauryl alcohol), tetradecan-1-ol (tetradecyl alcohol, myristyl alcohol), hexadecan-1-ol (hexadecyl alcohol, cetyl alcohol, palmityl alcohol), Octadecan-1-ol (octadecyl alcohol, stearyl alcohol), arachidyl alcohol (eicosan-1-ol), heneicosyl alcohol (heneicosan-1-ol), behenyl alcohol (docosan-1-ol), (9Z)-octadec-9-en-1-ol (oleyl alcohol), (9E)-octadec-9-en-1-ol (elaidyl alcohol), (9Z,12Z)-octadeca-9,12-dien-1-ol (linoleyl alcohol), (9Z,12Z,15Z)-octadeca-9,12,15-trien-1-ol (linolenoyl alcohol), gadoleyl alcohol ((9Z)-Eicos-9-en-1-ol), arachidonic acid alcohol ((5Z,8Z,11Z,14Z)-eicosa-5,8,11,14-tetraen-1-ol), erucyl alcohol ((13Z)-docos-13-en-1-ol), brassidyl alcohol ((13E)-docosen-1-ol), 2-octyldodecanol, 2-hexyldodecanol and / or 2-butyldodecanol.

[0164] The C 12 -C 30 By selecting an appropriate amount of the fatty alcohol (B2), the rate of film formation derived from the C1-C6 alkoxysilane is particularly strongly co-determined. For this reason, it has been proven that it is particularly preferred to use one or more C 12 -C 30 fatty alcohols (B2) in particular amounts within a specific range.

[0165] The second composition (B) is present in a total amount of 2.0 to 50.0% by weight, preferably 4.0 to 40.0% by weight, more preferably 6.0 to 30.0% by weight, even more preferably 8.0 to 20.0% by weight, and most preferably 10.0 to 15.0% by weight, based on the total weight of the composition (B), of one or more C 12 -C 30 When it contains a fatty alcohol (B2), it is particularly preferred.

[0177] Furthermore, a suitable amount of C 12 -C 30 fatty acid monoglyceride, C 12 -C 30 fatty acid diglyceride and / or C 12 -C 30 The choice of fatty acid triglyceride can also have a particularly strong influence on the rate of film formation derived from C1-C6 alkoxysilane. For this reason, in composition (B), one or more C 12 -C 30 fatty acid monoglyceride, C 12 -C 30 fatty acid diglyceride and / or C 12 -C 30 It has proven particularly preferable to use fatty acid triglyceride (B2) in an amount within a specific range, in particular.

[0178] Regarding the solution of the problems according to the invention, when the second composition (B) contains fatty acid monoglyceride, fatty acid diglyceride and / or fatty acid triglyceride (B2) in a total amount of 0.1 to 20.0% by weight, preferably 0.3 to 15.0% by weight, more preferably 0.5 to 10.0% by weight, and most preferably 0.8 to 5.0% by weight based on the total weight of composition (B), it has been found to be most particularly preferable. 12 -C 30 fatty acid monoglyceride, C 12 -C 30 fatty acid diglyceride and / or C 12 -C 30 fatty acid triglyceride (B2), it has been found to be most particularly preferable.

[0179] In a highly preferred embodiment, in the method according to the invention, the second composition (B) is present in a total amount of 0.1 to 20.0% by weight, preferably 0.3 to 15.0% by weight, more preferably 0.5 to 10.0% by weight, very particularly preferably 0.8 to 5.0% by weight, based on the total weight of the composition (B), of one or more C 12 -C 30 fatty acid monoglycerides, C 12 -C 30 fatty acid diglycerides and / or C 12 -C 30 fatty acid triglycerides (B2).

[0180] C 12 -C 30 fatty acid mono-, C 12 -C 30 fatty acid di- and / or C 12 -C 30 The fatty acid triglycerides can be used as the sole fat component (B2) in the composition (B). However, at least one C 12 -C 30 fatty acid monoglyceride, C 12 -C 30 fatty acid diglyceride and / or C 12 -C 30 fatty acid triglyceride is particularly preferably incorporated into the composition (B) in combination with at least one C 12 -C 30 fatty alcohol.

[0181] Furthermore, as a highly particularly preferred fat component (B2), the composition (B) can contain at least one hydrocarbon.

[0182] Hydrocarbons are compounds consisting only of carbon and hydrogen atoms having 8 to 80 carbon atoms. In this regard, for example, aliphatic hydrocarbons such as mineral oil, liquid paraffin oil (e.g., white mineral oil (paraffinium liquidum) or light liquid paraffin (paraffinum perliquidum)), isoparaffin oil, semi-solid paraffin oil, paraffin wax, hard paraffin (paraffin wax), petrolatum and polydecene are particularly preferred.

[0183] It has been found that liquid paraffin oil (e.g., white mineral oil (paraffinium liquidum) or light liquid paraffin (paraffinum perliquidum)) is particularly suitable in this context. White mineral oil, also known as white oil, is a particularly preferred hydrocarbon. White mineral oil is a mixture of refined saturated aliphatic hydrocarbons and consists of hydrocarbon chains having a C-chain distribution of 25 to 35 carbon atoms.

[0184] Very particularly satisfactory results were obtained when the composition (B) contained at least one hydrocarbon (B2) selected from the group of mineral oils including liquid kerosene oil, isoparaffin oil, semi-solid kerosene oil, kerosene wax, hard kerosene (paraffin wax), petrolatum and polydecene.

[0185] In a very preferred embodiment, the method according to the invention is characterized in that the second composition (B) comprises at least one fatty component (B2) from the group of hydrocarbons.

[0186] Furthermore, the rate of film formation from C1-C6 alkoxysilanes can be particularly strongly influenced also by the selection of a suitable amount of hydrocarbon. For this reason, it has been found that in the composition (B) it is particularly preferred to use one or more hydrocarbons, especially in a specific range of amounts.

[0187] Regarding the solution of the problems according to the present invention, when the second composition (B) contains one or more hydrocarbons (B2) in a total amount of 0.5 to 20.0% by weight, preferably 1.0 to 15.0% by weight, more preferably 1.5 to 10.0% by weight, and most preferably 2.0 to 8.0% by weight based on the total weight of the composition (B), it has been found to be extremely particularly preferable.

[0188] In a very particularly preferred embodiment, the method according to the present invention is characterized in that the second composition (B) contains one or more hydrocarbons (B2) in a total amount of 0.5 to 20.0% by weight, preferably 1.0 to 15.0% by weight, more preferably 1.5 to 10.0% by weight, and very particularly preferably 2.0 to 8.0% by weight based on the total weight of the composition (B).

[0189] The hydrocarbon can be used as the sole fatty component (B2) in the composition (B). However, it is particularly preferred to incorporate at least one hydrocarbon in combination with at least one other component into the composition (B).

[0190] The composition (B) is C 12 -C 30 Particularly preferably, it contains at least one fatty component (B2) from the group of fatty alcohols and at least one further fatty component from the group of hydrocarbons.

[0191] <Surfactant in the composition (B)> Since it contains water (B1) and a fatty component (B2), the composition (B) may be in the form of an emulsion. It has been proven particularly preferable to further use at least one surfactant in the composition (B) in order to further optimize the formation of the emulsion.

[0192] Therefore, it is very preferable when the composition (B) further contains at least one surfactant.

[0193] In another particularly preferred embodiment, the method according to the present invention is characterized in that the second composition (B) contains at least one surfactant.

[0194] The term surfactant (T) refers to surface-active substances that can form an adsorbed layer at the surface and interface or aggregate in the bulk phase to form micellar colloids or lyotropic mesophases. It is distinguished into anionic surfactants consisting of hydrophobic residues and negatively charged hydrophilic head groups, zwitterionic surfactants having both negative charges and compensating positive charges, cationic surfactants having positively charged hydrophilic groups in addition to hydrophobic residues, and nonionic surfactants having no charge but a strong dipole moment and strongly hydrating in an aqueous solution.

[0195] In a very particularly preferred embodiment, the method according to the invention is characterized in that the second composition (B) comprises at least one nonionic surfactant.

[0196] Nonionic surfactants contain, for example, polyol groups, polyalkylene glycol ether groups or combinations of polyols and polyglycol ether groups as hydrophilic groups. Such links include the following. · Adducts of 2 - 50 moles of ethylene oxide and / or 0 - 5 moles of propylene oxide to linear and branched fatty alcohols, fatty alcohol polyglycol ethers or fatty alcohol polypropylene glycol ethers or mixed fatty alcohol polyethers having 6 - 30 C atoms · Adducts of 2 - 50 moles of ethylene oxide and / or 0 - 5 moles of propylene oxide to linear and branched fatty acids, fatty acid polyglycol ethers or fatty acid polypropylene glycol ethers or mixed fatty acid polyethers having 6 - 30 carbon atoms · Adducts of 2 - 50 moles of ethylene oxide and / or 0 - 5 moles of propylene oxide to linear and branched alkylphenols, alkylphenol polyglycol ethers or alkyl polypropylene glycol ethers or mixed alkylphenol polyethers having 8 - 15 C atoms in the alkyl group ·End groups of 2 to 50 moles of ethylene oxide and / or 0 to 5 moles of propylene oxide added to linear and branched fatty alcohols containing 8 to 30 carbon atoms, fatty acids containing 8 to 30 carbon atoms, and alkylphenols containing 8 to 15 carbon atoms in the alkyl group, such as grades available under the trademarks Dehydol LS and Dehydol LT (Cognis). ·C12-C30 fatty acid mono- and diesters of adducts of 1 to 30 moles of ethylene oxide to glycerol ·Adducts of 5 to 60 moles of ethylene oxide to castor oil and hydrogenated castor oil ·Polyol fatty acid esters such as the commercially available products Hydagen HSP (Cognis) or Sovermol grades (Cognis). ·Alkoxylated triglycerides ·Alkoxylated fatty acid alkyl esters of formula (Tnio-1):

Chemical formula

Chemical formula

[0197] · Sugar surfactants of the fatty acid N-alkyl polyhydroxyalkylamide type, nonionic surfactants of formula (Tnio-3): [Chemical formula] [In the formula, R 5 CO is an aliphatic acyl group containing 6 to 22 carbon atoms, R 6 is hydrogen, an alkyl or 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 usually known substances obtained by reductively aminating a reducing sugar with ammonia, an alkylamine or an alkanolamine, followed by acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride. Fatty acid N-alkyl polyhydroxyalkylamides are preferably derived from reducing sugars having 5 or 6 carbon atoms, especially glucose. Accordingly, a preferred fatty acid N-alkyl polyhydroxyalkylamide is a fatty acid N-alkyl glucamide represented by formula (Tnio-4). [Chemical formula] Preferably, the glucamide of formula (Tnio-4) is used as a fatty acid-N-alkyl polyhydroxyalkylamide, wherein R8 represents a hydrogen or alkyl group, R 7 CO represents an acyl radical of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmitoleic 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 an industrial mixture thereof. Particularly preferred are fatty acid N-alkylglucosamides of formula (Tnio-4) obtained by reductively aminating glucose with methylamine followed by acylation with lauric acid or C12 / 14 coconut fatty acids or corresponding derivatives. Furthermore, polyhydroxyalkylamides can also be derived from maltose and palatinose.

[0198] The sugar surfactant can preferably be present in the composition used according to the invention in an amount of 0.1 to 20% by weight, based on the total composition. An amount of 0.5 to 15% by weight is preferred, and an amount of 0.5 to 7.5% by weight is particularly preferred.

[0199] Other typical examples of nonionic surfactants are fatty acid amide polyglycol ethers, fatty amine polyglycol ethers, mixed ethers or mixed formals, protein hydrolysates (especially plant products based on wheat) and polysorbates.

[0200] Alkylene oxide adducts of saturated straight-chain fatty alcohols and fatty acids each having 2 to 30 moles of ethylene oxide per mole of fatty alcohol or fatty acid and sugar surfactants are known to be preferred nonionic surfactants. Also, when they contain fatty acid esters of ethoxylated glycerol as nonionic surfactants, preparations with excellent properties are obtained.

[0201] These linkages are specified by the following parameters. The alkyl group R contains 6 to 22 carbon atoms and may be either straight-chain or branched. Primary straight-chain aliphatic groups and aliphatic groups branched at the 2-position by a methyl group are preferred. Such alkyl groups are, for example, 1-octyl, 1-decyl, 1-lauryl, 1-myristyl, 1-cetyl and 1-stearyl. Particularly preferred are 1-octyl, 1-decyl, 1-lauryl, 1-myristyl. When so-called "oxo-alcohols" are used as starting materials, compounds having an odd number of carbon atoms in the alkyl chain account for the majority.

[0202] Compounds having an alkyl group used as a surfactant may each be a homogeneous substance. However, in the production of these substances, it is usually preferred to start from natural plant or animal raw materials so that a mixture of substances having different alkyl chain lengths can be obtained depending on each raw material.

[0203] In the case of surfactants that are addition products of ethylene oxide and / or propylene oxide to fatty alcohols, or derivatives of these addition products, either products having a "normal" homolog distribution or products having a narrow homolog distribution can be used. The "normal" homolog distribution means a mixture of homologs obtained by the reaction of a fatty alcohol and an alkylene oxide using an alkali metal, an alkali metal hydroxide or an alkali metal alcoholate as a catalyst. On the other hand, when using, for example, hydrotalcite, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides or alcoholates as a catalyst, a narrowed homolog distribution can be obtained. The use of products with a narrow homolog distribution may be preferred.

[0204] When a second composition (B) containing at least one ethoxylated fatty alcohol having an ethoxylation degree of 80 to 120 is used in the method according to the present invention, particularly satisfactory results are obtained.

[0205] In another highly preferred embodiment, the method according to the present invention is such that the second composition (B) has the formula (T-I): [Chemical formula] [wherein, Ra is a saturated or unsaturated, straight-chain or branched C8-C 24 alkyl group, preferably a saturated straight-chain C 16 -bis C 18 alkyl group, and n is an integer from 80 to 120, preferably an integer from 90 to 110, and particularly preferably the number 100]. characterized by containing at least one nonionic surfactant represented by

[0206] A suitable nonionic surfactant of this type is the trade name Brij S100 or Brij S100 PA SG. This is a stearyl alcohol ethoxylated with 100 EO, commercially available from Croda and having the CAS number 9005-00-9.

[0207] Furthermore, in the method according to the present invention, when a second composition (B) containing at least one ethoxylated fatty alcohol having an ethoxylation degree of 10 to 40 is used, very particularly satisfactory results are obtained.

[0208] In another very particularly preferred embodiment, the method according to the present invention is such that the second composition (B) has the formula (T-II): [Chemical formula] [wherein, Rb is a saturated or unsaturated, unbranched or branched C8-C 24 alkyl group, preferably a saturated unbranched C 16 -C 18 alkyl group, and m is an integer from 10 to 40, preferably an integer from 20 to 35, and particularly preferably the number 30]. characterized by containing at least one nonionic surfactant represented by

[0209] A particularly suitable nonionic surfactant of this type is cetearyl-30. Cetearyl-30 is a mixture of cetyl alcohol and stearyl alcohol, each ethoxylated with 30 units of ethylene oxide. The mixture of cetyl alcohol and stearyl alcohol is called cetearyl alcohol. Cetearyl-30 has the CAS number 68439-49-6 and can be purchased, for example, from BASF under the trade name Eumulgin B3.

[0210] It has been found to be particularly preferred when composition (B) contains both at least one nonionic surfactant of formula (T-I) and at least one nonionic surfactant of formula (T-II).

[0211] <Polymer in composition (B)> In a further embodiment, composition (B) used in the method of the present invention can also be configured in the form of a gel containing water. Thus, as a further optional component, composition (B) can contain at least one polymer, particularly preferably a thickening polymer.

[0212] Suitable polymers herein can include, for example, the following. · Vinyl pyrrolidone / vinyl ester copolymers, such as those sold under the trademark of Luviskol® (BASF). Luviskol® VA64 and Luviskol® VA73, which are vinyl pyrrolidone / vinyl acetate copolymers respectively, are also preferred nonionic polymers. · Cellulose ethers such as hydroxypropyl cellulose, hydroxyethyl cellulose, methylhydroxypropyl cellulose, for example, those sold under the trademarks of Culminal® and Benecel® (AQUALON) and Natrosol® grades (Hercules). · Starch and its derivatives, particularly starch ethers, such as Structure® XL (National Starch), multifunctional salt-tolerant starch. · Shellac · Polyvinylpyrrolidone, such as those sold under the name of Luviskol® (BASF).

[0213] The polymer is preferably present in composition (B) in an amount of 0.05 to 10% by weight, based on the total amount of the composition. An amount of 0.1 to 5% by weight is particularly preferred.

[0214] In another very particularly preferred embodiment, the method of the present invention is characterized in that the second composition (B) comprises at least one thickening polymer, preferably at least one cellulose ether selected from the group consisting of hydroxyethyl cellulose, hydroxypropyl cellulose and methylhydroxypropyl cellulose.

[0215] <Solvent for composition (B)> Further studies leading to the present invention have shown that the use of at least one protic solvent in composition (B) also reduces the reaction rate of C1-C6 alkoxysilanes when contacted with composition (A). For this reason, at least one solvent can be further added to composition (B).

[0216] The protic solvent has at least one hydroxy group. Without being bound by this theory, the solvent can also react with the C1-C6 alkoxysilane via its hydroxyl group, but the reaction between the solvent and the C1-C6 alkoxysilane is thought to proceed more slowly than the similar reaction between water and the C1-C6 alkoxysilane. In summary, the hydrolysis and / or condensation reaction of the C1-C6 alkoxysilane is thus reduced.

[0217] For example, suitable solvents that can be used include 1,2-propylene glycol, 1,3-propylene glycol, ethylene glycol, 1,2-butylene glycol, dipropylene glycol, ethanol, isopropanol, diethylene glycol monoethyl ether, glycerol, phenoxyethanol and / or benzyl alcohol.

[0218] In another highly particularly preferred embodiment, the method according to the invention is characterized in that the second composition (B) comprises at least one solvent selected from the group consisting of 1,2-propylene glycol, 1,3-propylene glycol, ethylene glycol, 1,2-butylene glycol, dipropylene glycol, ethanol, isopropanol, diethylene glycol monoethyl ether, glycerol, phenoxyethanol and / or benzyl alcohol.

[0219] Particularly preferred is a composition (B) containing 1,2-propylene glycol as the solvent.

[0220] 1,2-Propylene glycol is also called 1,2-propanediol and has the CAS numbers 57-55-6 [(RS)-1,2-dihydroxypropane], 4254-14-2 [(R)-1,2-dihydroxypropane] and 4254-15-3 [(S)-1,2-dihydroxypropane]. Ethylene glycol is also known as 1,2-ethanediol and has the CAS number 107-21-1. Glycerol is also known as 1,2,3-propanetriol and has the CAS number 56-81-5. Phenoxyethanol has the Cas number 122-99-6.

[0221] All of the above solvents are commercially available from various chemical manufacturers such as Aldrich or Fluka.

[0222] By using the above solvents in suitable application amounts, the rate of film formation derived from C1-C6 alkoxysilanes is determined particularly strongly together. For this reason, it has been found that it is particularly preferred to use one or more solvents, especially in a specific amount range.

[0223] Particularly preferred is the case where the second composition (B) contains one or more solvents in a total amount of 1.0 to 35.0% by weight, preferably 4.0 to 25.0% by weight, more preferably 8.0 to 20.0% by weight, and most preferably 10.0 to 15.0% by weight, based on the total weight of the composition (B).

[0224] When the second composition (B) contains at least one solvent selected from the group consisting of 1,2-propylene glycol, 1,3-propylene glycol, ethylene glycol, 1,2-butylene glycol, dipropylene glycol, ethanol, isopropanol, diethylene glycol monoethyl ether, glycerol, phenoxyethanol and / or benzyl alcohol in a total amount of 1.0 to 35.0% by weight, preferably 4.0 to 25.0% by weight, more preferably 8.0 to 20.0% by weight, and most preferably 10.0 to 15.0% by weight based on the total weight of the composition (B), it is particularly preferred.

[0225] <Other cosmetic ingredients in composition (B)> In addition to the very particularly preferred ingredients already described above, composition (B) may further contain one or more additional cosmetic ingredients.

[0226] The cosmetic ingredients that can optionally be used in composition (B) can be any suitable ingredients for imparting further beneficial properties to the product. For example, composition (A) can contain a solvent, a thickening or film-forming polymer, a surfactant compound from the group of nonionic, cationic, anionic or zwitterionic / amphoteric surfactants, a pigment, a direct dye, a coloring compound from the group of oxidation dye precursors, C8-C 30 It may include fatty alcohols, hydrocarbon compounds, fatty components from the group of fatty acid esters, acids and bases belonging to the group of pH adjusters, fragrances, preservatives, plant extracts and protein hydrolysates.

[0227] When the method according to the invention is a method for coloring keratinous substances, composition (B) can very preferably contain at least one coloring compound selected from the group consisting of pigments and / or direct dyes.

[0228] The selection of these other substances is made by those skilled in the art according to the desired properties of the agent. For any other optional ingredients and the amounts of use thereof, express reference is made to the relevant manuals known to those skilled in the art.

[0229] <pH value of the composition in the method of the present invention> In further experiments, it has been found that the pH value of composition (A) and / or (B) can affect the hydrolysis or condensation reaction occurring during use, as described above. In particular, an alkaline pH value has been found to stop the condensation at the oligomer stage. The more acidic the reaction mixture, the more strongly the condensation seems to proceed, and the higher the molecular weight of the silane condensate formed during the condensation. Therefore, composition (A) and / or (B) preferably has a pH of 5.0 to 12.0, preferably 6.0 to 11.5, more preferably 8.5 to 11.0, and most preferably 9.0 to 11.0.

[0230] The water content of composition (A) is at most 10.0% by weight and is preferably set even lower. In some embodiments, the water content of composition (B) can also be selected to be low. In particular, in the case of a composition with a very low water content, it may prove difficult to measure the pH value using the usual methods known from the prior art (measurement of the pH value using a glass electrode via a combined electrode or pH indicator paper). Therefore, the pH value according to the present invention is obtained after mixing or diluting with distilled water in a 1:1 weight ratio.

[0231] Accordingly, the corresponding pH is measured, for example, after mixing 50 g of the composition of the present invention with 50 g of distilled water.

[0232] In another very particularly preferred embodiment, the method according to the present invention is characterized in that composition (A) and / or (B) has a pH of 5.0 to 12.0, preferably 6.0 to 11.5, more preferably 8.5 to 11.0, and most preferably 9.0 to 11.0 after being diluted with distilled water in a 1:1 weight ratio.

[0233] If it is necessary to add an alkalizing agent and / or an acidifying agent to the reaction mixture to adjust this alkaline pH, this may be the case. The pH value in the present invention is the pH value measured at a temperature of 22°C.

[0234] For example, ammonia, alkanolamines and / or basic amino acids can be used as the alkalizing agent.

[0235] The alkanolamine can be selected from primary amines having a C2-C6 alkyl backbone with at least one hydroxyl group. Preferred alkanolamines are selected from the group formed by 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, 2-amino-2-methylpropan-1,3-diol.

[0236] In the present invention, the amino acid is an organic compound containing at least one protonatable amino group and at least one -COOH or one -SO3H group in its structure. Preferred amino acids are aminocarboxylic acids, especially α-(alpha)-aminocarboxylic acids and ω-aminocarboxylic acids, with ω-aminocarboxylic acids being particularly preferred.

[0237] According to the present invention, the basic amino acid is an amino acid having an isoelectric point pI greater than 7.0.

[0238] The basic α-aminocarboxylic acid contains at least one asymmetric carbon atom. In the context of the present invention, both possible enantiomers can be equally used as a specific compound or a mixture thereof, especially as a racemate. However, it is particularly advantageous to use the preferred isomeric form in the natural state, usually the L-form.

[0239] The basic amino acid is selected from the group formed by arginine, lysine, ornithine and histidine, particularly preferably arginine and lysine. Thus, in another particularly preferred embodiment, the agent according to the invention is characterized in that the alkalizing agent is a basic amino acid from the group of arginine, lysine, ornithine and / or histidine.

[0240] Furthermore, inorganic alkalizing agents can also be used. The inorganic alkalizing agents that can be used according to the invention are preferably selected from the group consisting of sodium hydroxide, potassium hydroxide, calcium hydroxide, barium hydroxide, sodium phosphate, potassium phosphate, sodium silicate, sodium metasilicate, potassium silicate, sodium carbonate and potassium carbonate.

[0241] Particularly preferred alkalizing agents are ammonia, 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, 2-amino-2-methylpropan-1,3-diol, arginine, lysine, ornithine, histidine, sodium hydroxide, potassium hydroxide, calcium hydroxide, barium hydroxide, sodium phosphate, potassium phosphate, sodium silicate, sodium metasilicate, potassium silicate, sodium carbonate and potassium carbonate.

[0242] In addition to the above-mentioned alkalizing agents, those skilled in the art are also well acquainted with common acidifying agents for fine-tuning the pH value. According to the invention, preferred acidifying agents are edible acids such as citric acid, acetic acid, malic acid or tartaric acid and diluted mineral acids.

[0243] <Coating of compositions (A) and (B)> The method according to the invention comprises applying both compositions (A) and (B) to the keratinous material. It is essential for this method that compositions (A) and (B) come into contact with each other on the keratinous material. As mentioned above, this contact can be achieved either by premixing (A) and (B) or by applying (A) and (B) successively to the keratinous material. Thus, the contact of the components of (A) and (B) can be carried out in the preparation before application or during application on the keratinous material itself.

[0244] Research leading to the present invention has shown that composition (B) containing water (B1) and an aldehyde (B2) can have an optimal effect on the low-moisture silane blend (i.e., composition (A)), especially when compositions (A) and (B) are mixed before use.

[0245] This mixing can be carried out, for example, by stirring or shaking. It is particularly advantageous to prepare the two compositions (A) and (B) separately in two containers and then transfer the entire amount of composition (A) from its container to the container containing the second composition (B) before use.

[0246] In a very particularly preferred embodiment, the method according to the invention is characterized in that the composition prepared immediately before application by mixing the first composition (A) with the second composition (B) is applied to the keratinous material.

[0247] The two compositions (A) and (B) can be mixed in different ratios.

[0248] Particularly preferably, composition (A) is used in the form of a relatively high-concentration low-moisture silane blend and is quasi-diluted by mixing with composition (B). For this reason, it is particularly preferred to mix composition (A) with an excess of composition (B) on a weight basis. For example, 1 part by weight of (A) can be mixed with 20 parts by weight of (B), or 1 part by weight of (A) can be mixed with 10 parts by weight of (B), or 1 part by weight of (A) can be mixed with 5 parts by weight of (B).

[0249] In a very particularly preferred embodiment, the method according to the invention is characterized in that a composition prepared immediately before application by mixing a first composition (A) and a second composition (B) in a quantitative ratio (A) / (B) of 1:5 to 1:20 is applied to the keratinous material.

[0250] In principle, it is also possible to use the composition (A) in excess relative to the composition (B) on a weight basis. For example, 20 parts by weight of (A) may be mixed with 1 part by weight of (B), 10 parts by weight of (A) may be mixed with 1 part by weight of (B), or 5 parts by weight of (A) may be mixed with 1 part by weight of (B).

[0251] Furthermore, it is also conceivable to apply the compositions (A) and (B) continuously to the keratinous material so that the contact of (A) and (B) occurs only on the keratinous material. In this embodiment, preferably, the keratin matrix is not washed between the application of the compositions (A) and (B), that is, the keratin matrix is not treated with water or water and a surfactant.

[0252] In one embodiment, only both the compositions (A) and (B) can be applied to the keratinous material. When the method according to the invention is used to dye the keratinous material, it may also be very preferred that not only the two compositions (A) and (B) but also at least one further third composition (C) is applied to the keratinous material.

[0253] In a method for coloring a keratinous material, the third composition (C) can be, for example, a composition comprising at least one coloring compound selected from the group consisting of pigments and / or direct dyes.

[0254] In a further embodiment, very particularly preferred is the method according to the invention, wherein the following is applied to the keratinous material. · A further composition (C) comprising the following At least one coloring compound selected from the group consisting of pigments and / or direct dyes.

[0255] Various embodiments using three compositions (A), (B) and (C) are according to the present invention.

[0256] In one embodiment, it is particularly preferred to prepare a mixture of the three compositions (A), (B) and (C) before application and then apply this mixture to the keratinous material.

Subsequently, the third composition (C) containing the coloring compound can be added to the keratinous material.

[0259] In a particularly preferred embodiment, the method according to the invention is characterized in that the composition obtained immediately before application by mixing the first composition (A) with the second composition (B) is applied to the keratinous material, and subsequently the composition (C) is applied to the keratinous material.

[0260] In other words, a very particularly preferred method according to the invention is characterized in that in a first step, the composition prepared immediately before application by mixing the first composition (A) and the second composition (B) is applied to the keratinous material, and in a second step, a further composition (C) is applied to the keratinous material.

[0261] In addition to the compositions (A) and (B) - or (A), (B) and (C) - in the method according to the invention, a fourth composition (D) may be applied to the keratinous material. The application of the composition (D) is particularly preferred in the dyeing method in order to reseal the previously obtained dyeing. For this sealing, the composition (D) can contain, for example, at least one film-forming polymer.

[0262] In other words, the following method of the invention applied to the keratinous material is particularly preferred. · A further composition (D) comprising At least one film-forming polymer.

[0263] <Coloring compound> When the compositions (A) and (B) - or, optionally additionally (C) and / or (D) - are used in the dyeing method, one or more coloring compounds may be used.

[0264] In particular, the preparation (B) and / or, optionally used preparation (C) and / or (D) may further contain at least one coloring compound.

The solubility in water can be measured, for example, by the following method. Weigh 0.5 g of the pigment into a beaker. Add a stir bar. Then add 1 liter of distilled water. Heat this mixture to 25 °C for 1 hour while stirring with a magnetic stirrer. After this time, if undissolved components of the pigment are visible in the mixture, the solubility of the pigment is less than 0.5 g / L. If the pigment and water mixture cannot be visually evaluated because of the high strength of the pigment that can be finely dispersed, filter the mixture. If a part of the undissolved pigment remains on the filter paper, the solubility of the pigment is less than 0.5 g / L.

[0267] Suitable coloring pigments can be of inorganic and / or organic origin.

[0268] In a preferred embodiment, the composition according to the invention is characterized by containing at least one coloring compound selected from the group consisting of inorganic and / or organic pigments.

[0269] Preferred coloring pigments are selected from synthetic or natural inorganic pigments.

[0279] In a further aspect, the composition or preparation according to the invention can also comprise one or more coloring compounds selected from the group consisting of organic pigments.

[0280] The organic pigments according to the invention are, for example, the corresponding insoluble organic dyes or color lakes which can be selected from the group of nitroso, nitro - azo, xanthene, anthraquinone, isoindolinone, quinacridone, perinone, perylene, diketo - pyrrolopyrrole, indigo, thioindigo, dioxazine and / or triarylmethane compounds.

[0281] Examples of particularly preferred organic pigments are carmine, quinacridone, phthalocyanine, sorghum, blue pigments having Color Index numbers CI42090, CI69800, CI69825, CI73000, CI74100, CI74160, yellow pigments having Color Index numbers CI11680, CI11710, CI15985, CI19140, CI20040, CI21100, CI21108, CI47000, CI47005, green pigments having Color Index numbers CI61565, CI61570, CI74260, orange pigments having Color Index numbers CI11725, CI15510, CI45370, CI71105, and red pigments having Color Index numbers CI12085, CI12120, CI12370, CI12420, CI12490, CI14700, CI15525, CI15580, CI15620, CI15630, CI15800, CI15850, CI15865, CI15880, CI17200, CI26100, CI45380, CI45410, CI58000, CI73360, CI73915 and / or CI75470.

[0282] In another particularly preferred embodiment, the method according to the invention is characterized in that the composition (B) and / or the composition (C) comprises at least one coloring compound selected from the group of organic pigments consisting of carmine, quinacridone, phthalocyanine, sorghum, blue pigments having Color Index numbers CI42090, CI69800, CI69825, CI73000, CI74100, CI74160, yellow pigments having Color Index numbers CI11680, CI11710, CI15985, CI19140, CI20040, CI21100, CI21108, CI47000, CI47005, green pigments having Color Index numbers CI61565, CI61570, CI74260, orange pigments having Color Index numbers CI11725, CI15510, CI45370, CI71105, and red pigments having Color Index numbers CI12085, CI12120, CI12370, CI12420, CI12490, CI14700, CI15525, CI15580, CI15620, CI15630, CI15800, CI15850, CI15865, CI15880, CI17200, CI26100, CI45380, CI45410, CI58000, CI73360, CI73915 and / or CI75470.

[0283] The organic pigment may be a color paint. In the context of the present invention, the term color lacquer means particles containing a layer of absorbed dye, the particles and the dye units being insoluble under the above conditions. The particles can be, for example, inorganic substances, such as calcium borosilicate, calcium aluminum borosilicate, or even aluminum.

[0284] For example, alizarin color varnish can be used.

[0285] Since it has excellent resistance to light and temperature, the use of the above pigments is particularly preferred in the means according to the present invention. Furthermore, it is also preferred if the pigments used have a certain particle size. This particle size, on the one hand, results in a uniform distribution of the pigments in the formed polymer film, and on the other hand, avoids the frizzy hair or rough skin feeling after the application of cosmetics. Therefore, according to the present invention, at least one pigment has an average particle diameter D 50 in the range of 1.0 to 50 μm, preferably 5.0 to 45 μm, preferably 10 to 40 μm, 14 to 30 μm. 50 The average particle diameter D

[0286] For coloring keratinous substances, pigments of specific shapes can also be used. For example, pigments based on layered and / or lens-shaped substrate platelets can be used. Furthermore, colorants based on substrate platelets containing vacuum metallized pigments can also be used.

[0287] This type of substrate platelet has an average thickness of at most 50 nm, preferably less than 30 nm, particularly preferably at most 25 nm, for example at most 20 nm. The average thickness of the substrate platelet is at least 1 nm, preferably at least 2.5 nm, particularly preferably at least 5 nm, for example at least 10 nm. The preferred range of the thickness of the substrate wafer is 2.5 to 50 nm, 5 to 50 nm, 10 to 50 nm, 2.5 to 30 nm, 5 to 30 nm, 10 to 30 nm; 2.5 to 25 nm, 5 to 25 nm, 10 to 25 nm, 2.5 to 20 nm, 5 to 20 nm and 10 to 20 nm. Preferably, each substrate plate has a thickness as uniform as possible.

[0288] Due to the thin thickness of the substrate platelet, the pigment exhibits particularly high hiding power.

[0289] The substrate plate has a monolithic structure. By "monolithic" in this specification is meant that, while structural changes can occur in the substrate platelets, it is composed of a single closed unit without fractures, delamination, or inclusions. The substrate platelets are preferably uniformly structured, i.e., there is no concentration gradient within the platelets. In particular, the substrate platelets do not have a layered structure and do not have particles or particle distributions therein.

[0290] The size of the substrate platelets can be adjusted according to each application purpose, particularly the desired effect on the keratinous substance. Typically, the substrate platelets have an average maximum diameter of about 2 - 200 μm, particularly about 5 - 100 μm.

[0291] In a preferred embodiment, the aspect ratio, expressed as the ratio of the average size to the average thickness, exceeds at least 80, preferably at least 200, more preferably at least 500, and even more preferably 750. The average size of the uncoated substrate platelets is the d50 value of the uncoated substrate platelets. Unless otherwise specified, the d50 value was determined using a Sympatec Helos device equipped with a Qicell wet dispersion. To prepare the sample, the sample to be analyzed was pre-dispersed in isopropanol for 3 minutes.

[0292] The substrate platelets can be composed of any material that can be formed in a platelet shape.

[0293] They may be of natural origin or synthetically produced. Materials that can constitute the substrate platelets include metals and metal alloys, metal oxides, preferably aluminum oxide, inorganic compounds and minerals such as mica and (semi) precious stones, and plastics. Preferably, the substrate platelets are composed of a metal (alloy).

[0294] Any metal suitable for metallic luster pigments can be used. Such metals include iron, steel, and all air- and water-resistant (semi) metals such as platinum, zinc, chromium, molybdenum, silicon, and their alloys such as aluminum bronze and brass. Preferred metals are aluminum, copper, silver, and gold. Preferred substrate platelets include aluminum platelets and brass platelets, with aluminum substrate platelets being particularly preferred.

[0295] The layered substrate platelet is characterized by edges of an irregular structure and is also called "cornflake" from its appearance.

[0296] Due to their irregular structure, pigments based on layered substrate platelets produce a high proportion of scattered light. Furthermore, pigments based on layered substrate platelets do not completely cover the existing color of keratinous substances and can achieve, for example, an effect similar to natural graying.

[0297] The lens-shaped (= lens-type) substrate platelet has regular round edges and is also called "silver dollar" from its appearance. Due to their regular structure, the proportion of reflected light is dominant in pigments based on lens-shaped substrate platelets.

[0298] Vacuum metallized pigments (VMP) can be obtained, for example, by releasing a metal, metal alloy or metal oxide from a suitably coated film. They are characterized by a particularly thin thickness of the substrate platelet in the range of 5 - 50 nm and a particularly smooth surface with increased reflectivity. Substrate platelets containing vacuum metallized pigments are also called VMP substrate platelets in the context of the present invention. Aluminum VMP substrate platelets can be obtained, for example, by releasing aluminum from a metallized film.

[0299] Metal or metal alloy substrates can be passivated, for example, by anodization (oxide layer) or chromate treatment.

[0300] Uncoated layered, lens-shaped, and / or VPM substrate plates, especially those made of metal or metal alloy, highly reflect incident light and create light and dark flops, but have no color impression.

[0301] The color impression can be created, for example, by optical interference effects. Such pigments can be based on at least single-coated substrate platelets. These show interference effects by superposing various refracted and reflected light rays.

[0302] Therefore, preferred pigments are those based on coated layered substrate platelets. The substrate wafer preferably has at least one coating B of a high refractive index metal oxide with a coating thickness of at least 50 nm. Preferably, there is another coating A between coating B and the surface of the substrate wafer. Optionally, there is a further coating C on a layer B different from the lower layer B.

[0303] All materials suitable for coatings A, B, and C are film-like substances that can be permanently applied to the substrate platelets and, in the case of coatings A and B, have the required optical properties. The coated portion of the surface of the substrate platelet is sufficient to obtain a pigment with a gloss effect. For example, only the upper and / or lower surfaces of the substrate platelet can be coated, and the side surfaces can be omitted. Preferably, the entire surface of any passivated substrate platelet, including the side surfaces, is covered with coating B. Thus, the substrate platelet is completely covered with coating B. This improves the optical properties of the pigment and increases its mechanical and chemical resistance. The above also applies to layer A and, if present, preferably to layer C.

[0304] Multiple coatings A, B, and / or C can be present in each case, but the coated substrate wafer preferably has only one coating A, B, and, if present, only C in each case.

[0305] Coating B is composed of at least one high refractive index metal oxide. The high refractive index material has a refractive index of at least 1.9, preferably at least 2.0, more preferably at least 2.4. Preferably, Coating B contains at least 95% by weight, more preferably at least 99% by weight of the high refractive index metal oxide.

[0306] Coating B has a thickness of at least 50 nm. Preferably, the thickness of Coating B is 400 nm or less, more preferably 300 nm or less.

[0307] Suitable high refractive index metal oxides for Coating B are preferably metal oxides that selectively absorb light (i.e., are colored), such as iron(III) oxide (α- and γ-Fe2O3, red), cobalt(II) oxide (blue), chromium(III) oxide (green), titanium(III) oxide (blue, usually present as a mixture with titanium oxynitride and titanium nitride), and vanadium(V) oxide (orange), and mixtures thereof. Colorless high refractive index oxides such as titanium oxide and / or zirconium oxide are also suitable.

[0308] Coating B may preferably contain 0.001 to 5% by weight, particularly preferably 0.01 to 1% by weight of a selective absorption dye based on the total amount of Coating B. Suitable dyes are organic and inorganic dyes that can be stably incorporated into the metal oxide coating.

[0309] Coating A preferably has at least one low refractive index metal oxide and / or metal oxide hydrate. Preferably, Coating A contains at least 95% by weight, more preferably at least 99% by weight of the low refractive index metal oxide (hydrate). The low refractive index material has a refractive index of 1.8 or less, preferably 1.6 or less.

[0310] Low refractive index metal oxides suitable for Coating A include, for example, silicon oxide, silicon oxide hydrate, aluminum oxide, aluminum oxide hydrate, boron oxide, germanium oxide, manganese oxide, magnesium oxide, and mixtures thereof with preferably silicon dioxide. Coating A preferably has a thickness of 1 to 100 nm, particularly preferably 5 to 50 nm, and particularly preferably 5 to 20 nm.

[0311] Preferably, the distance between the surface of the substrate platelet and the inner surface of Coating B is at most 100 nm, particularly preferably at most 50 nm, and particularly preferably at most 20 nm. By setting the thickness of Coating A, i.e., the distance between the surface of the substrate platelet and Coating B, within the above specific range, a pigment with high hiding power can be ensured.

[0312] When the pigment based on the layered substrate platelet has only one layer A, the pigment preferably has a layered substrate platelet of aluminum and a layer A of silica. When the pigment based on the layered substrate platelet has layers A and B, the pigment preferably has a layered substrate platelet of aluminum, a layer A of silica, and a layer B of iron oxide.

[0313] According to a preferred embodiment, the pigment has a further Coating C of a metal oxide (hydrate) different from the underlying Coating B. Suitable metal oxides include silicon (di)oxide, silicon oxide hydrate, aluminum oxide, aluminum oxide hydrate, zinc oxide, tin oxide, titanium dioxide, zirconium oxide, iron(III) oxide, and chromium(III) oxide. Silicon dioxide is preferred.

[0314] Coating C preferably has a thickness of 10 to 500 nm, more preferably 50 to 300 nm. By providing, for example, a Coating C based on TiO2, better interference can be achieved while maintaining high hiding power.

[0315] Layers A and C function as corrosion protection and as chemical and physical stabilizers. Particularly preferred layers A and C are silica or alumina applied by a sol-gel process. This process involves dispersing an uncoated or already layer A- and / or layer B-coated layered substrate platelet in a solution of a metal alkoxide such as tetraethyl orthosilicate or aluminum triisopropoxide (usually a solution in an organic solvent or a mixture of an organic solvent and water containing 50% by weight or more of an organic solvent such as a C1-C4 alcohol), adding a weak base or weak acid to hydrolyze the metal alkoxide (50% organic solvent such as a C1-C4 alcohol), and adding a weak base or acid to hydrolyze the metal alkoxide, thereby forming a metal oxide film on the surface of the (coated) substrate platelet.

[0316] Layer B can be produced, for example, by hydrolysis of one or more organometallic compounds and / or by precipitation of one or more dissolved metal salts, and by any subsequent post-treatment (e.g., by annealing, conversion of the formed hydroxide-containing layer to an oxide layer).

[0317] Coatings A, B, and / or C can each be composed of a mixture of two or more metal oxides (hydrates), but each coating is preferably composed of one metal oxide (hydrate) each.

[0318] Pigments based on coated layered or lens-shaped substrate platelets, or pigments based on coated VMP substrate platelets preferably have a thickness of 70 to 500 nm, particularly preferably 100 to 400 nm, particularly preferably 150 to 320 nm, for example 180 to 290 nm. Due to the thin thickness of the substrate platelets, the pigments exhibit particularly high hiding power. The thin thickness of the coated substrate platelets is achieved by keeping the thickness of the uncoated substrate platelets small, but can also be achieved by adjusting the thicknesses of coating A and, if present, C to the smallest possible values. The thickness of coating B determines the color impression of the pigment.

[0319] In the keratinous material, the adhesion and abrasion resistance of the pigment based on the coated substrate platelet can be significantly improved by further modifying the outermost layer, layer A, B or C with an organic compound such as a silane, phosphate ester, titanate, borate or carboxylic acid according to the structure. In this case, the organic compound is bonded to the outermost surface, preferably the surface of the metal oxide-containing layer A, B or C. The outermost layer refers to the layer that is spatially farthest from the layered substrate platelet. The organic compound is preferably a functional silane compound that can be bonded to the metal oxide-containing layer A, B or C. These may be either monofunctional or bifunctional compounds. Examples of bifunctional organic compounds include methacryloxypropenyltrimethoxysilane, 3-methacryloxypropyltrimethoxysilane, 3-acryloxypropyltrimethoxysilane, 2-acryloxyethyltrimethoxysilane, 3-methacryloxy-propyltriethoxysilane, 3-acryloxypropyltrimethoxysilane, 2-methacryloxyethyl-triethoxysilane, 2-acryloxyethyltriethoxysilane, 3-methacryloxypropyltris(methoxyethoxy)silane, 3-methacryloxypropyltris(butoxyethoxy)silane, 3-methacryloxy-propyltris(propoxy)silane, 3-methacryloxypropyltris(butoxy)silane, 3-acryloxy-propyltris(methoxyethoxy)silane, 3-acryloxypropyltris(butoxyethoxy)silane, 3-acryloxy-propyltris(butoxy)silane, vinyltrimethoxysilane, vinyltriethoxysilane, vinylethyldichlorosilane, vinylmethyldiacetoxysilane, vinylmethyldichlorosilane, vinylmethyldiethoxysilane, vinyltriacetoxysilane, vinyltrichlorosilane, phenylvinyldiethoxysilane, or phenylallyldichlorosilane. Further, modification with a monofunctional silane, alkylsilane or arylsilane may be performed. This has only one functional group and can form a covalent bond with the surface pigment based on the coated layered substrate platelet (i.e., the outermost metal oxide-containing layer), or the metal surface if it is not completely covered.The hydrocarbon residues of the silane are directed away from the pigment. Depending on the type and nature of the hydrocarbon residues of the silane, various degrees of hydrophobicity of the pigment are achieved. Examples of such silanes include hexadecyltrimethoxysilane, propyltrimethoxysilane, etc. Particularly preferred are pigments based on silica-coated aluminum substrate platelets surface-modified with monofunctional silanes. Octyltrimethoxysilane, octyltriethoxysilane, hexadecyltrimethoxysilane and hexadecyltriethoxysilane are particularly preferred. The changed surface properties / hydrophobization enables improvements with respect to adhesion, abrasion resistance and placement in coatings.

[0320] Suitable pigments based on layered substrate platelets include, for example, pigments of the VISIONAIRE series from Eckart.

[0321] Pigments based on lens-shaped substrate platelets can be obtained, for example, under the name Alegrace® Gorgeous from Schlenk Metallic Pigments GmbH.

[0322] Pigments based on substrate platelets containing vacuum metallized pigments can be obtained, for example, under the name Alegleaces® Merverous or Aleglase® Aurous from Schlenk Metlic Pigments GmbH.

[0323] One or more pigments can each be used in an amount of 0.001 to 20% by weight, 0.05 to 5% by weight, based on the total weight of the composition or preparation according to the invention.

[0324] As coloring compounds, the composition according to the invention can also contain one or more direct dyes. Direct acting dyes are dyes that are applied directly onto the hair and do not require an oxidative process to form color. Direct dyes are usually nitrophenylenediamine, nitroaminophenol, azo dyes, anthraquinone, triarylmethane dyes or indophenol.

[0325] Within the scope of the present invention, a direct dye has a solubility in water (760 mmHg) at 25 °C greater than 0.5 g / L and is thus not regarded as a pigment. Preferably, a direct dye in the meaning of the present invention has a solubility in water (760 mmHg) at 25 °C greater than 1.0 g / L. More preferably, a direct dye in the meaning of the present invention has a solubility in water (760 mmHg) at 25 °C greater than 1.5 g / L.

[0326] Direct dyes can be classified into anionic, cationic and non-ionic direct dyes.

[0327] In a further preferred embodiment, the agent according to the present invention is characterized in that it contains at least one anionic, cationic and / or non-ionic direct dye as a coloring compound.

[0328] In a further preferred embodiment, the method according to the present invention is characterized in that composition (B) and / or composition (C) contains at least one coloring compound selected from the group consisting of anionic, non-ionic, and / or cationic direct dyes.

[0329] Suitable cationic direct dyes include Basic Blue 7, Basic Blue 26, 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 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.

[0330] As nonionic direct dyes, nonionic nitro and quinone dyes and neutral azo dyes can be used. Suitable nonionic direct dyes are the following international designations 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, known compounds listed therein, 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, picramic acid and its salts, 2-amino-6-chloro-4-nitrophenol, 4-ethylamino-3-nitrobenzoic acid and 2-chloro-6-ethylamino-4-nitrophenol.

[0331] Anionic direct dyes are also called 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, the protonated forms (-COOH, -SO3H) of the carboxylic acid group or sulfonic acid group are their deprotonated forms (-COO - , -SO3 -It exists in equilibrium with (the form in which it exists). As the pH decreases, the proportion of the protonated form increases. When a direct dye is used in the form of its salt, the carboxylic acid group or sulfonic acid group exists in the deprotonated form and is neutralized with the corresponding stoichiometrically equivalent cation to maintain electrical neutrality. The acid dyes in the present invention can also be used in the form of their sodium salts and / or their potassium salts.

[0332] The acid dyes within the scope of the present invention have a solubility in water at 25 °C (760 mmHg) greater than 0.5 g / L and are thus not regarded as pigments. Preferably, the acid dyes within the scope of the present invention have a solubility in water at 25 °C (760 mmHg) greater than 1.0 g / L.

[0333] The alkaline earth salts (such as calcium salts and magnesium salts) or aluminum salts of acid dyes often have lower solubility than the corresponding alkali salts. If the solubility of these salts is less than 0.5 g / L (25 °C, 760 mmHg), these salts do not fall within the definition of direct dyes.

[0334] The essential characteristic of acid dyes is the ability to form an anionic charge, and the carboxylic acid group or sulfonic acid group involved is usually linked to different chromophore systems. Suitable chromophore systems can be found, for example, in the structures of nitrophenylenediamine, nitroaminophenol, azo dyes, anthraquinone dyes, triarylmethane dyes, xanthene dyes, rhodamine dyes, oxazine dyes and / or indophenol dyes.

[0336] For example, the solubility of an anionic direct dye in water can be measured as follows. Place 0.1 g of the anionic direct dye in a beaker. Add a stir bar. Then add 100 ml of water. Heat this mixture to 25 °C while stirring on a magnetic stirrer. Stir it for 60 minutes. Then, visually evaluate the aqueous mixture. If there is still an undissolved residue, increase the amount of water, for example, by 10 ml increments. Add water until the amount of dye used is completely dissolved. If the strength of the dye is so high that the dye-water mixture cannot be visually evaluated, filter the mixture. If some of the undissolved dye remains on the filter paper, repeat the solubility test using a larger amount of water. If 0.1 g of an anionic direct dye dissolves in 100 ml of water at 25 °C, the solubility of that dye is 1.0 g / L.

[0337] Acid Yellow 1 is called disodium 8-hydroxy-5,7-dinitro-2-naphthalenesulfonate and has a solubility in water of at least 40 g / L (25 °C).

[0338] Acid Yellow 3 is a mixture of the monoacid and disulfonic acid sodium salts of 2-(2-quinolyl)-1H-inden-1,3(2H)-dione and has a solubility in water of 20 g / L (25 °C).

[0339] Acid Yellow 9 is the disodium salt of 8-hydroxy-5,7-dinitro-2-naphthalenesulfonic acid and has a solubility in water exceeding 40 g / L (25 °C).

[0340] 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.

[0345] Acid Blue 9 is the disodium salt of 2-({4-[N-ethyl(3-sulfonatobenzyl)]amino}phenyl}4-[(N-ethyl(3-sulfonatobenzyl)imino]-2,5-cyclohexadien-1-ylidene}methyl)-benzenesulfonate and its solubility in water is greater than 20 wt% (25°C).

[0346] Thermochromic dyes can also be used. Thermochromism is the property of a substance to reversibly or irreversibly change its color in relation to temperature. This can be done by changing the intensity and / or the maximum value of the wavelength.

[0347] Finally, it is also possible to use photochromic dyes. Photochromism includes the property of reversibly or irreversibly changing its color depending on irradiation with light, especially ultraviolet light. This can be done by changing the maximum value of the intensity and / or wavelength.

[0348] <Film-forming polymer> The above preparations, preparations (B), (C) and (D), and very preferably preparation (D) may contain at least one film-forming polymer.

[0349] The polymer is a macromolecule with a molecular weight of at least 1000 g / mol, preferably at least 2500 g / mol, and particularly preferably at least 5000 g / mol, and consists of the same repeating organic units. The polymer of the present invention may be a synthetic polymer produced by the polymerization of one type of monomer, or may be a synthetic polymer produced by the polymerization of different types of monomers that are structurally different from each other. When the polymer is produced by polymerizing one type of monomer, it is called a homopolymer. When different types of monomers with different structures are used in the polymerization, the resulting polymer is called a copolymer.

[0350] The maximum molecular weight of the polymer depends on the degree of polymerization (the number of polymerized monomers) and the batch size, and is determined by the polymerization method. In the present invention, the maximum molecular weight of the film-forming hydrophobic polymer is 10 7 g / mol or less, preferably 10 6 g / mol or less, and particularly preferably 10 5 g / mol or less.

[0351] In the context of the present invention, a film-forming polymer is a polymer that can form a film on a substrate, such as a keratin substance or keratin fibers. The formation of the film can be demonstrated, for example, by observing the keratin substance treated with the polymer under a microscope.

[0352] The film-forming polymer may be hydrophilic or hydrophobic.

[0353] In a first aspect, it may be preferable to use at least one hydrophobic film-forming polymer in the preparations (B), (C) and / or (D), and particularly in the preparation (D).

[0354] A hydrophobic polymer is defined as a polymer having a solubility in water at 25 °C (760 mmHg) of less than 1% by weight.

[0355] The solubility of the film-forming hydrophobic polymer in water can be measured, for example, as follows. Place 1.0 g of the polymer in a beaker. Make up to 100 g with water. Add a stir bar and heat the mixture to 25 °C while stirring on a magnetic stirrer. Stir it for 60 minutes. Then visually evaluate the aqueous mixture. If the polymer-water mixture cannot be visually evaluated due to its high turbidity, filter the mixture. If a portion of the undissolved polymer remains on the filter paper, the solubility of the polymer is less than 1% by weight.

[0356] Examples of these polymers include acrylic polymers, polyurethanes, polyesters, polyamides, polyureas, cellulose polymers, nitrocellulose polymers, silicone polymers, acrylamide polymers and polyisoprene.

[0365] Homopolymers and copolymers of N-vinylpyrrolidone, vinylcaprolactam, vinyl-(C1-C6)alkyl-pyrrole, vinyl-oxazole, vinyl-thiazole, vinylpyrimidine, vinylimidazole can be mentioned as suitable polymers based on vinyl monomers.

[0366] Furthermore, copolymers of octylacrylamide / acrylate / butylaminoethyl methacrylate such as those marketed by NATIONAL STARCH under the trade names AMPHOMER® or LOVOCRYL® 47, or copolymers of acrylate / octylacrylamide sold by NATIONAL STARCH under the trade names DERMACRYL® LT and DERMACRYL® 79 are particularly suitable.

These block copolymers can be copolymers containing one or more other blocks in addition to styrene blocks such as styrene / ethylene, styrene / ethylene / butylene, styrene / butylene, styrene / isoprene, styrene / butadiene. Such polymers are commercially available under the trade name "Luvitol HSB" from BASF.

[0369] Furthermore, when the preparations (B), (C) and / or (D), especially the preparation (D), contain at least one film-forming polymer selected from the group consisting of homopolymers and copolymers of acrylic acid, homopolymers and copolymers of methacrylic acid, homopolymers and copolymers of acrylic acid esters, homopolymers and copolymers of methacrylic acid esters, homopolymers and copolymers of acrylamide, homopolymers and copolymers of methacrylamide, homopolymers and copolymers of vinyl pyrrolidone, homopolymers and copolymers of vinyl alcohol, homopolymers and copolymers of vinyl acetate, homopolymers and copolymers of ethylene, homopolymers and copolymers of propylene, homopolymers and copolymers of styrene, polyurethanes, polyesters and polyamides, it was possible to obtain a strong and washfast dyeing.

[0371] In a first aspect, it may be preferred to use at least one hydrophilic film-forming polymer in the preparation (B), (C) and / or (D), especially the preparation (D).

[0372] The hydrophilic polymer is a polymer having a solubility in water at 25 °C (760 mmHg) greater than 1% by weight, preferably greater than 2% by weight.

[0373] The solubility of the film-forming hydrophilic polymer in water can be measured, for example, as follows. Place 1.0 g of the polymer in a beaker. Make up to 100 g with water. Add a stirring fish and heat the mixture to 25 °C while stirring on a magnetic stirrer. Stir it for 60 minutes. Then visually evaluate the aqueous mixture. A completely dissolved polymer appears uniform to the naked eye. If the polymer-water mixture cannot be visually evaluated due to the high turbidity of the mixture, filter the mixture. If no undissolved polymer remains on the filter paper, the solubility of the polymer is greater than 1% by weight.

[0374] Nonionic, anionic and cationic polymers can be used as the film-forming hydrophilic polymer.

[0376] Furthermore, it is particularly preferred to use polyvinylpyrrolidone (PVP) and / or vinylpyrrolidone-containing copolymers as the film-forming hydrophilic polymer.

[0377] In another very particularly preferred embodiment, the agent according to the invention is characterized in that it contains at least one film-forming hydrophilic polymer selected from the group consisting of polyvinylpyrrolidone (PVP) and copolymers of polyvinylpyrrolidone.

[0378] It is more preferred if the agent according to the invention contains polyvinylpyrrolidone (PVP) as the film-forming hydrophilic polymer. Surprisingly, the washing fastness of the staining obtained with the agent containing PVP(b9 was also particularly good.

[0379] Particularly suitable polyvinylpyrrolidones are available, for example, under the product name Luviskol® K from BASF SE, especially Luviskol® K90 or Luviskol® K85 from BASF SE.

[0380] PVP K30 is sold by Ashland (ISP, POI Chemicals) and can also be used as another explicitly very suitable polyvinylpyrrolidone (PVP). PVP K30 is a polyvinylpyrrolidone that dissolves well in cold water and has a CAS number of 9003-39-8. The molecular weight of PVP K30 is approximately 40000 g / mol.

[0381] Other particularly suitable polyvinylpyrrolidones are substances known under the trade names LUVITEC K17, LUVITEC K30, LUVITEC K60, LUVITEC K80, LUVITEC K85, LUVITEC K90 and LUVITEC K115 and are available from BASF.

[0382] The use of film-forming hydrophilic polymers from the group of copolymers of polyvinylpyrrolidone also results in a particularly good and wash-fast finish of the color.

[0383] Polyvinylpyrrolidone-vinyl ester copolymers such as those sold under the trademark Luviskol® (BASF) are particularly suitable film-forming hydrophilic polymers. Both Luviscol® VA64 and Luviskol® VA73 are vinylpyrrolidone / vinyl acetate copolymers and are particularly preferred nonionic polymers.

For example, the VP / vinylcaprolactam / DMAPA acrylates copolymer is sold by Ashland under the trade name Aquaflex® SF-40. For example, the VP / DMAPA acrylates copolymer is sold by Ashland under the product name Styleze CC-10 and is a very preferred vinylpyrrolidone-containing copolymer.

[0389] Furthermore, when a nonionic film-forming hydrophilic polymer was used as the film-forming hydrophilic polymer, strongly dyed keratinous substances, especially hair, with particularly good washing fastness could be obtained.

[0390] In a first embodiment, it may be preferred if preparation (B), (C) and / or (D), preparation (D) comprises at least one nonionic film-forming hydrophilic polymer.

[0391] According to the present invention, a nonionic polymer is understood to be a polymer that does not have a structural unit containing a permanent cationic group or anionic group that must be compensated by a counterion while maintaining electronic neutrality under standard conditions in a protic solvent (such as water). Cationic groups include quaternized ammonium groups but not protonated amines. Anionic groups include carboxylic acid groups and sulfonic acid groups.

[0392] Preferably, as a nonionic film-forming hydrophilic polymer, a product containing at least one polymer selected from the group consisting of the following is provided. · Polyvinylpyrrolidone · Copolymers of N-vinylpyrrolidone and vinyl esters of carboxylic acids having 2 to 18 carbon atoms, copolymers of N-vinylpyrrolidone and vinyl acetate · Copolymers of N-vinylpyrrolidone, N-vinylimidazole, and methacrylamide · Copolymers of N-vinylpyrrolidone, N-vinylimidazole, and acrylamide · Copolymers of N-vinylpyrrolidone and N,N-di(C1-C4)-alkylamino-(C2-C4)-alkylacrylamide

[0393] When a copolymer of N-vinylpyrrolidone and vinyl acetate is used, it is also preferred when the molar ratio of the structural units contained in the monomer N-vinylpyrrolidone to the structural units of the polymer containing the monomer vinyl acetate is in the range of 20:80 to 80:20, particularly 30:70 to 60:40. Suitable copolymers of vinylpyrrolidone and vinyl acetate are available, for example, from BASF SE under the trademarks Luviskol® VA37, Luviskol® VA55, Luviskol® VA64, and Luviskol® VA73.
