INCREASING THE STABILITY OF AGENTS FOR THE TREATMENT OF KERATIN MATERIAL

Description

[0001] The present application is in the field of cosmetics and relates to a method for treating keratinous material, in particular human hair, which comprises the application of three compositions (A), (B) and (C). Composition (A) is a low-water preparation containing at least two organic C1-C6 alkoxysilanes, and composition (B) contains, in addition to water, at least one aromatic or aliphatic aldehyde with 2 to 20 carbon atoms. Composition (C) contains at least one coloring compound from the group of pigments and / or direct dyes.

[0002] A second object of the present invention is a multi-component packaging unit (kit-of-parts) for coloring keratinous material, which is separately packaged in three packaging units comprising the three compositions (A), (B) and (C) described above.

[0003] Altering the shape and color of keratin fibers, especially hair, is an important area of ​​modern cosmetics. Depending on the desired color, professionals are familiar with various dyeing systems for changing hair color. For permanent, intense colorations with good colorfastness and gray coverage, oxidation dyes are typically used. These dyes usually contain oxidation dye precursors, so-called developer components and coupler components, which react with oxidizing agents such as hydrogen peroxide to form the actual dyes. Oxidation dyes are characterized by very long-lasting color results.

[0004] When using direct dyes, pre-formed pigments diffuse from the dye into the hair fiber. Compared to oxidative hair coloring, dyes produced with direct dyes are less durable and wash out more quickly. Dyes made with direct dyes typically remain on the hair for between 5 and 20 washes.

[0005] The use of color pigments is well-known for temporary color changes to hair and / or skin. Color pigments are generally understood to be insoluble, coloring substances. These are present in the coloring formulation in the form of small particles and are simply deposited on the hair fibers and / or skin surface. Therefore, they can usually be removed completely after a few washes with surfactant-containing cleansers. Various products of this type are available on the market under the name "hair mascara."

[0006] EP 2168633 B1 and US 2010 / 0083446 A1 address the challenge of creating long-lasting hair colors using pigments. The documents demonstrate that by using a combination of pigment, an organic silicon compound, a hydrophobic polymer, and a solvent, it is possible to create hair colors that are particularly resistant to shampooing.

[0007] The organic silicon compounds used in EP 2168633 B1 are reactive compounds from the class of alkoxy silanes. These alkoxy silanes hydrolyze rapidly in the presence of water, forming hydrolysis products and / or condensation products, depending on the respective amounts of alkoxy silane and water used. The influence of the amount of water used in this reaction on the properties of the hydrolysis or condensation product is described, for example, in WO 2013068979 A2.

[0008] When these alkoxy silanes, or their hydrolysis and condensation products, are applied to keratinous material, a film or coating forms on the keratin, completely enveloping it and thus significantly influencing its properties. Possible applications include the permanent styling or reshaping of keratin fibers. In these processes, the keratin fibers are mechanically shaped and then fixed in this form by the formation of the aforementioned coating. Another particularly suitable application is the coloring of keratin; in this application, the coating or film is created in the presence of a coloring compound, such as a pigment. The pigment-colored film remains on the keratin material or fibers, resulting in surprisingly wash-resistant colors.

[0009] The major advantage of the alkoxy silane-based staining principle lies in the fact that the high reactivity of this class of compounds enables very rapid coating. Extremely good staining results can thus be achieved after very short application times of just a few minutes. However, in addition to these advantages, the high reactivity of alkoxy silanes also entails some disadvantages.

[0010] Due to their high reactivity, organic alkoxy silanes cannot be formulated with large quantities of water, as an excess of water initiates immediate hydrolysis followed by polymerization. The polymerization that occurs when alkoxy silanes are stored in aqueous media manifests as thickening or gelation of the aqueous preparation. This makes the preparations so highly viscous, gel-like, or gelatinous that they can no longer be applied evenly to the keratin material. Furthermore, storing alkoxy silanes in the presence of high water volumes results in a loss of reactivity, making the formation of a durable coating on the keratin material impossible.

[0011] For these reasons, it is necessary to store organic alkoxy silanes in an anhydrous or low-water environment and to package the corresponding preparations in a separate container. Due to their high reactivity, alkoxy silanes can react not only with water but also with other cosmetic ingredients. To avoid any undesirable reactions, preparations containing alkoxy silanes preferably contain no other ingredients or only selected ingredients that have proven to be chemically inert to alkoxy silanes. Accordingly, the concentration of alkoxy silanes in the preparation is preferably chosen to be relatively high. Low-water preparations containing relatively high concentrations of alkoxy silanes can also be referred to as "silane blends."

[0012] For application to the keratin material, the user must now convert this relatively highly concentrated silane blend into a ready-to-use mixture. In this ready-to-use mixture, the concentration of organic alkoxy silanes is reduced, and the application mixture also contains a higher proportion of water (or an alternative ingredient), which triggers the polymerization leading to the coating.

[0013] It has proven to be an extremely big challenge to optimally adapt the polymerization rate, i.e. the rate at which the coating forms on the keratin material, to the application conditions.

[0014] When applied to human hair, an excessively rapid polymerization rate means that the polymerization is complete before all sections of hair can be treated. Therefore, excessively rapid polymerization makes full-head treatment impossible. During the dyeing process, excessively rapid polymerization results in an extremely uneven color, so that the sections of hair treated last are only poorly colored.

[0015] On the other hand, if polymerization is too slow, all areas of the hair can be treated without time pressure, but this increases the application time or the dwell time of the formulations on the keratin material. Therefore, if polymerization is too slow, the major advantage of this coloring technology—the formation of colorfast shades within a very short application time—is lost.

[0016] The objective of the present application was to find a method for treating keratinous material by which the polymerization rate of the organic alkoxysilanes could be adapted to the application conditions, in particular to the conditions prevailing when applied to the human head. In other words, a method was sought by which the organic alkoxysilanes remain reactive long enough to allow whole-head treatment without unduly prolonging the application period.

[0017] Surprisingly, it has been found that this task can be fully accomplished by treating the keratin material in a process involving the application of three compositions (A), (B), and (C). The first composition (A) is the previously described low-water silane blend. The second composition (B) contains water and also includes at least one aromatic or aliphatic aldehyde with 2 to 20 carbon atoms. During application, both compositions (A) and (B) come into contact with each other, either by pre-mixing (A) and (B) or by successively applying (A) and (B) to the keratin material. The third composition (C) contains at least one coloring compound from the group of pigments and / or direct dyes.

[0018] A first object of the present invention is a method for treating keratinous material, in particular human hair, in which the following are applied to the keratinous material. a first composition (A) which, based on the total weight of the composition (A), contains (A1) less than 10% by weight water and (A21) at least one organic C1-C6 alkoxysilane selected from the group consisting of (3-aminopropyl)triethoxysilane, (3-aminopropyl)trimethoxysilane, (2-aminoethyl)triethoxysilane, (2-aminoethyl)trimethoxysilane, (3-dimethylaminopropyl)triethoxysilane, (3-dimethylaminopropyl)trimethoxysilane, (2-dimethylaminoethyl)triethoxysilane, (2-dimethylaminoethyl)trimethoxysilane and / or their condensation products, and (A22) at least one organic C1-C6 alkoxysilane selected from the group consisting of methyltrimethoxysilane, methyltriethoxysilane, ethyltrimethoxysilane, ethyltriethoxysilane, hexyltrimethoxysilane, Hexyltriethoxysilane, octyltrimethoxysilane, octyltriethoxysilane, dodecyltrimethoxysilane, dodecyltriethoxysilane and / or their condensation products, and a second composition (B),which contains (B1) water and (B2) one or more aromatic or aliphatic aldehydes with 2 to 20 carbon atoms, and a third composition (C) which contains (C1) at least one coloring compound from the group of pigments and / or direct dyes.

[0019] It has been shown that the aldehydes (B2) contained in the aqueous composition (B) reduce the polymerization rate of the organic C1-C6 alkoxy silanes (A21) and (A22) upon contact with composition (A). Surprisingly, the reactivity of the organic C1-C6 alkoxy silanes (A21) and (A22) could thus be optimally adapted to the application conditions prevailing in a whole-head hair coloring process. Even more complex or time-consuming coloring techniques, such as the coloring of strands specifically arranged on the head, could be realized using the process according to the invention. When the two compositions (A) and (B) were used in a coloring process on keratin material, especially on human hair, colorations with particularly high uniformity, rub fastness, and wash fastness could be produced in this way. Treatment of keratinous material

[0020] Keratinous material includes hair, skin, and nails (such as fingernails and / or toenails). Wool, fur, and feathers also fall under the definition of keratinous material.

[0021] The term "keratinous material" preferably refers to human hair, human skin, and human nails, especially fingernails and toenails. Human hair is particularly preferred as a keratinous material.

[0022] The term "agents for treating keratinous material" includes, for example, agents for dyeing keratinous material, agents for transforming or shaping keratinous material, particularly keratinous fibers, or agents for conditioning or maintaining keratinous material. Agents produced according to the inventive process are particularly well-suited for dyeing keratinous material, especially keratinous fibers, which are preferably human hair.

[0023] The term "coloring agent" is used within the scope of this invention to describe the coloring of keratin material, particularly hair, by the use of coloring compounds such as pigments, mica, direct dyes, thermochromic and photochromic dyes. The use of pigments is particularly preferred. In this coloring process, the aforementioned coloring compounds are deposited in a particularly homogeneous and smooth film on the surface of the keratin material or diffuse into the keratin fiber. The film forms in situ through oligomerization or polymerization of the organic alkoxy silanes, and through the interaction of the coloring compound and organic silicon compounds and optionally other components, such as a film-forming polymer. Water content (A1) in composition (A)

[0024] The method according to the invention is characterized by the application of a first composition (A) to the keratinous material.

[0025] To ensure sufficiently high storage stability, composition (A) is characterized by being low in water, preferably essentially anhydrous. Therefore, composition (A) contains less than 10 wt% water, based on the total weight of composition (A).

[0026] At a water content of just under 10 wt%, compositions (A) are stable for extended periods of time. However, to further improve storage stability and to ensure sufficiently high reactivity of the organic C1-C6 alkoxy silanes (A21) and (A22), it has proven particularly advantageous to further reduce the water content in composition (A). For this reason, first composition (A) preferably contains 0.01 to 9.5 wt%, more preferably 0.01 to 8.0 wt%, even more preferably 0.01 to 6.0 wt%, and most preferably 0.01 to 4.0 wt% water (A1) based on the total weight of composition (A).

[0027] In a particularly preferred embodiment, a method according to the invention is characterized in that the first composition (A) - based on the total weight of the composition (A) - contains 0.01 to 9.5 wt.%, preferably 0.01 to 8.0 wt.%, more preferably 0.01 to 6.0 and most preferably 0.01 to 4.0 wt.% water (A1). Organic C1-C6 alkoxy silanes (A21) and (A22) and / or their condensation products in composition (A)

[0028] The composition (A) is characterized in that it contains one or more organic C 1 -C 6 -alkoxy silanes (A21) and / or their condensation products and one or more organic C 1 -C 6 -alkoxy silanes (A22) and / or their condensation products.

[0029] Organic C1-C6 alkoxy silanes are organic, non-polymeric silicon compounds.

[0030] Organic silicon compounds, also alternatively referred to as organosilicon compounds, are compounds that either have a direct silicon-carbon bond (Si-C) or in which the carbon is linked to the silicon atom via an oxygen, nitrogen, or sulfur atom. The organic silicon compounds according to the invention are preferably compounds containing one to three silicon atoms. Particularly preferably, the organic silicon compounds contain one or two silicon atoms.

[0031] According to IUPAC rules, the term silane refers to a group of chemical compounds based on a silicon backbone and hydrogen. In organic silanes, the hydrogen atoms are wholly or partially replaced by organic groups such as (substituted) alkyl groups and / or alkoxy groups.

[0032] A characteristic feature of the C1-C6 alkoxy silanes according to the invention is that at least one C1-C6 alkoxy group is directly bonded to a silicon atom. The C1-C6 alkoxy silanes according to the invention thus comprise at least one structural unit R'R"R‴Si-O-(C1-C6 alkyl), where the R', R" and R‴ groups represent the three remaining bonding valences of the silicon atom.

[0033] The C1-C6 alkoxy group(s) bonded to the silicon atom are highly reactive and hydrolyze rapidly in the presence of water. The reaction rate depends, among other things, on the number of hydrolyzable groups per molecule. If the hydrolyzable C1-C6 alkoxy group is an ethoxy group, the organic silicon compound preferentially contains a structural unit R'R"R‴Si-O-CH2-CH3. The substituents R', R", and R‴ represent the three remaining free valences of the silicon atom.

[0034] Even the addition of small amounts of water leads first to hydrolysis and then to a condensation reaction between the organic alkoxysilanes. For this reason, both the organic alkoxysilanes (A21) and (A22) as well as their condensation products can be present in the composition.

[0035] A condensation product is understood to be a product that is formed by the reaction of at least two organic C 1 -C 6 -alkoxy silanes with the elimination of water and / or with the elimination of a C 1 -C 6 -alkanol.

[0036] The condensation products can be, for example, dimers, but also trimers or oligomers, with the condensation products being in equilibrium with the monomers.

[0037] Depending on the amount of water used or consumed in the hydrolysis, the equilibrium shifts from monomeric C 1 -C 6 -alkoxysilane to condensation product.

[0038] Organic silicon compounds (A21) are particularly well suited to solving the problem set out in the invention. (3-Aminopropyl)triethoxysilane (3-Aminopropyl)trimethoxysilane (2-Aminoethyl)triethoxysilane (2-Aminoethyl)trimethoxysilane (3-Dimethylaminopropyl)triethoxysilane (3-Dimethylaminopropyl)trimethoxysilane (2-Dimethylaminoethyl)triethoxysilane. (2-Dimethylaminoethyl)trimethoxysilane and / or

[0039] The process according to the invention is characterized in that the first composition (A) contains at least one organic C1-C6 alkoxysilane (A21) selected from the group consisting of (3-Aminopropyl)triethoxysilane (3-Aminopropyl)trimethoxysilane (2-Aminoethyl)triethoxysilane (2-Aminoethyl)trimethoxysilane (3-Dimethylaminopropyl)triethoxysilane (3-Dimethylaminopropyl)trimethoxysilane (2-Dimethylaminoethyl)triethoxysilane, (2-Dimethylaminoethyl)trimethoxysilane and / or their condensation products.

[0040] The aforementioned organic silicon compounds (A21) are commercially available. (3-Aminopropyl)trimethoxysilane, for example, can be purchased from Sigma-Aldrich. (3-Aminopropyl)triethoxysilane is also commercially available from Sigma-Aldrich.

[0041] In further dyeing experiments, it also proved to be particularly advantageous if at least one organic C1-C6 alkoxy-silane (A22) was used in the process according to the invention.

[0042] Organic silicon compounds (A22) are particularly well suited to solving the problem set out in the invention. Methyltrimethoxysilane Methyltriethoxysilane Ethyltrimethoxysilane Ethyltriethoxysilane n-Hexyltrimethoxysilane (also known as hexyltrimethoxysilane) n-Hexyltriethoxysilane (also known as hexyltriethoxysilane) n-Octyltrimethoxysilane (also known as octyltrimethoxysilane) n-Octyltriethoxysilane (also known as octyltriethoxysilane) n-Dodecyltrimethoxysilane (also referred to as dodecyltrimethoxysilane) and / or n-Dodecyltriethoxysilane (also known as dodecyltriethoxysilane).

[0043] The process according to the invention is characterized in that the first composition (A) contains at least one organic C1-C6 alkoxysilane (A22) selected from the group consisting of Methyltrimethoxysilane Methyltriethoxysilane Ethyltrimethoxysilane Ethyltriethoxysilane Hexyltrimethoxysilane Hexyltriethoxysilane Octyltrimethoxysilane Octyltriethoxysilane Dodecyltrimethoxysilane, dodecyltriethoxysilane, and / or their condensation products.

[0044] The corresponding hydrolysis or condensation products include, for example, the following compounds: Hydrolysis of C1-C6 alkoxysilane of formula (SI) with water (reaction scheme using 3-aminopropyltriethoxysilane as an example):

[0045] Depending on the amount of water used, the hydrolysis reaction can also occur multiple times per C1-C6-alkoxy-silane used: or

[0046] Hydrolysis of C1-C6 alkoxysilane of formula (S-IV) with water (reaction scheme using methyltrimethoxysilane as an example):

[0047] Depending on the amount of water used, the hydrolysis reaction can also occur multiple times per C1-C6-alkoxy-silane used: or

[0048] Possible condensation reactions include (shown using the mixture of (3-aminopropyl)triethoxysilane and methyltrimethoxysilane): and / or and / or and / or and / or and / or and / or

[0049] In the above exemplary reaction schemes, the condensation to a dimer is shown in each case, but further condensations to oligomers with several silane atoms are also possible and preferred.

[0050] Both partially hydrolyzed and fully hydrolyzed C1-C6 alkoxysilanes of formula (SI) can participate in these condensation reactions, undergoing condensation with unreacted, partially or fully hydrolyzed C1-C6 alkoxysilanes of formula (SI). In this case, the C1-C6 alkoxysilanes of formula (SI) react with themselves.

[0051] Furthermore, both partially hydrolyzed and fully hydrolyzed C1-C6 alkoxysilanes of formula (SI) can participate in the condensation reactions, undergoing condensation with unreacted, partially or fully hydrolyzed C1-C6 alkoxysilanes of formula (S-IV). In this case, the C1-C6 alkoxysilanes of formula (SI) react with the C1-C6 alkoxysilanes of formula (S-IV).

[0052] Furthermore, both partially hydrolyzed and fully hydrolyzed C1-C6 alkoxysilanes of formula (S-IV) can participate in the condensation reactions, undergoing condensation with unreacted, partially or fully hydrolyzed C1-C6 alkoxysilanes of formula (S-IV). In this case, the C1-C6 alkoxysilanes of formula (S-IV) react with themselves.

[0053] The composition (A) according to the invention can contain one or more organic C1-C6 alkoxysilanes (A2) in varying proportions. The person skilled in the art determines these proportions depending on the desired thickness of the silane coating on the keratin material and the amount of keratin material to be treated.

[0054] Particularly stable preparations with very good staining results in application could be obtained when the composition (A) - based on its total weight - contains one or more organic C 1 -C 6 -alkoxysilanes (A2) and / or the condensation products thereof in a total amount of 30.0 to 85.0 wt.%, preferably 35.0 to 80.0 wt.%, more preferably 40.0 to 75.0 wt.%, even more preferably 45.0 to 70.0 wt.% and most preferably 50.0 to 65.0 wt.%.

[0055] In a further embodiment, a particularly preferred method is characterized in that the first composition (A) - based on the total weight of the composition (A) - contains one or more organic C 1 -C 6 -alkoxysilanes (A2) and / or the condensation products thereof in a total amount of 30.0 to 85.0 wt.%, preferably 35.0 to 80.0 wt.%, more preferably 40.0 to 75.0 wt.%, even more preferably 45.0 to 70.0 wt.% and most preferably 50.0 to 65.0 wt.%. Other cosmetic ingredients in the composition (A)

[0056] In principle, the composition (A) may also contain one or more additional cosmetic ingredients.

[0057] The cosmetic ingredients that may be optionally included in composition (A) can be any suitable components to impart further beneficial properties to the product. For example, composition (A) may contain a solvent, a thickening or film-forming polymer, a surfactant from the group of nonionic, cationic, anionic or zwitterionic / amphoteric surfactants, coloring compounds from the group of pigments, direct dyes, oxidation dye precursors, fatty components from the group of C8-C30 fatty alcohols, hydrocarbon compounds, fatty acid esters, acids and bases belonging to the group of pH regulators, perfumes, preservatives, plant extracts and protein hydrolysates.

[0058] The selection of these additional substances will be made by a person skilled in the art according to the desired properties of the product. Regarding further optional components and the quantities of these components used, explicit reference is made to the relevant handbooks known to those skilled in the art.

[0059] As previously described, the organic C1-C6 alkoxysilanes (A21) and (A22) can react not only with water but also with other cosmetic ingredients. To avoid these undesirable reactions, preparations (A) containing alkoxysilanes preferably contain no other ingredients or only selected ingredients that have proven to be chemically inert to the C1-C6 alkoxysilanes. In this context, it has proven particularly advantageous to include in composition (A) a cosmetic ingredient from the group consisting of hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane, and / or decamethylcyclopentasiloxane.

[0060] In a further particularly preferred embodiment, a method according to the invention is characterized in that the first composition (A) additionally contains at least one cosmetic ingredient from the group consisting of hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane.

[0061] Hexamethyldisiloxane has the CAS number 107-46-0 and can be purchased commercially, for example, from Sigma-Aldrich.

[0062] Octamethyltrisiloxane has the CAS number 107-51-7 and is also commercially available from Sigma-Aldrich.

[0063] Decamethyltetrasiloxane has the CAS number 141-62-8 and is also commercially available from Sigma-Aldrich. Hexamethylcyclotrisiloxane has CAS number 541-05-9. Octamethylcyclotetrasiloxane has CAS number 556-67-2. Decamethylcyclopentasiloxane has CAS number 541-02-6.

[0064] The use of hexamethyldisiloxane in composition (A) has proven to be particularly preferred. Particularly preferred is the presence of hexamethyldisiloxane – based on the total weight of composition (A) – in amounts of 10.0 to 50.0 wt.%, preferably 15.0 to 45.0 wt.%, further preferably 20.0 to 40.0 wt.%, even more preferably 25.0 to 35.0 wt.%, and most preferably 31.0 to 34.0 wt.% in composition (A).

[0065] In a further particularly preferred embodiment, a method according to the invention is characterized in that the first composition (A) - based on the total weight of the composition (A) - contains 10.0 to 50.0 wt.%, preferably 15.0 to 45.0 wt.%, more preferably 20.0 to 40.0 wt.%, even more preferably 25.0 to 35.0 wt.% and most preferably 31.0 to 34.0 wt.% hexamethyldisiloxane. Water content (B1) in composition (B)

[0066] A characteristic feature of the method according to the invention is the application of a second composition (B) to the keratinous material, in particular to human hair.

[0067] When applied to the keratinous material, compositions (A) and (B) come into contact, and this contact is particularly preferably achieved by prior mixing of the two compositions (A) and (B). Mixing (A) and (B) produces the ready-to-use keratin treatment agent; that is, the storage-stable or storable silane blend (A) is converted into its reactive form upon contact with (B). Mixing compositions (A) and (B) initiates a polymerization reaction starting from the alkoxy-silane monomers or alkoxy-silane oligomers, which ultimately leads to the formation of the film or coating on the keratin material.

[0068] The more water comes into contact with the organic C1-C6 alkoxy silane(s), the more pronounced the polymerization reaction becomes. For example, if composition (B) contains a very high amount of water, the monomeric or oligomeric silane condensates previously present in the water-poor composition (A) now polymerize very rapidly to form polymers of higher or high molecular weight. The high-molecular-weight silane polymers then form the film on the keratinous material. For this reason, water (B1) is an essential ingredient of composition (B).

[0069] The amount of water in composition (B) can influence the polymerization rate of the organic C1-C6 alkoxysilanes (A21) and (A22) at the time of application. However, to ensure a uniform color result when coloring hair all over the head, the polymerization rate, i.e., the speed at which the coating forms, should not be too high. For this reason, it has proven particularly advantageous to keep the amount of water in composition (B) relatively low.

[0070] Particularly uniform coloring over the entire head could be obtained when the composition (B) - based on the total weight of the composition (B) - contains 5.0 to 90.0 wt.%, preferably 15.0 to 85.0 wt.%, more preferably 25.0 to 80.0 wt.%, not further preferably 35.0 to 75.0 wt.% and most preferably 45.0 to 70.0 wt.% water (B1).

[0071] In a further particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) - based on the total weight of the composition (B) - contains 5.0 to 90.0 wt.%, preferably 15.0 to 85.0 wt.%, more preferably 25.0 to 80.0 wt.%, not further preferably 35.0 to 75.0 wt.% and most preferably 45.0 to 70.0 wt.% water (B1). Aldehydes (B2) in composition (B)

[0072] The composition (B) is further characterized by its content of at least one aromatic or aliphatic aldehyde with 2 to 20 carbon atoms (B2).

[0073] Aldehydes are defined as organic compounds that possess at least one aldehyde group (-CHO) as a functional group. Aldehydes according to the invention (B2) can also possess two or more aldehyde groups. In addition to this at least one aldehyde group, the organic compound can also bear further functional groups, such as at least one hydroxyl group, at least one C1-C6 alkyl group, at least one C1-C6 alkoxy group, at least one halogen atom 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 carboxyl group (-COOH) or a salt thereof, or at least one nitro group.

[0074] Aldehydes according to the invention are composed of 2 to 20 carbon atoms and can be aromatic or aliphatic.

[0075] An aromatic aldehyde comprises at least one aromatic ring, which may be 5-membered or, more preferably, 6-membered. Aromatic 5-membered rings are preferably heterocyclic. Aromatic 6-membered rings may be heterocyclic or carbocyclic.

[0076] Accordingly, aromatic, carbocyclic aldehydes generally comprise at least 7 carbon atoms (aromatic, carbocyclic 6-membered ring plus at least one aldehyde group) and at most 20 carbon atoms. The aromatic carbocyclic ring of the aldehydes according to the invention can, for example, comprise a benzene ring or a naphthalene ring.

[0077] Aliphatic aldehydes are compounds that do not contain an aromatic ring system. Aliphatic compounds can be based on alkyl groups or alkyl chains, which may be interrupted by heteroatoms, and the entire chain may be unbranched or branched. Aliphatic compounds can also be cyclic compounds that do not form an aromatic ring system. A cycloalkane ring, such as a cyclohexane or cyclopentane ring, can be an example of a carbocyclic, non-aromatic ring.

[0078] Surprisingly, it has been found that the use of at least one aromatic or aliphatic aldehyde with 2 to 20 carbon atoms (B2) optimizes the reaction rate of the organic C 1 -C 6 -alkoxy-silanes in such a way that a particularly uniform coloring on the entire head is made possible.

[0079] 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) with 7 to 20 carbon atoms.

[0080] In a further particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) contains at least one aromatic, carbocyclic aldehyde (B2) with 7 to 20 carbon atoms.

[0081] Carbocycles are cyclic compounds that contain only carbon atoms in the ring. An aromatic, carbocyclic aldehyde (B2) according to the invention, with 7 to 20 carbon atoms, therefore possesses an aromatic ring, the ring system itself being composed exclusively of carbon atoms.

[0082] The simplest aromatic carbocyclic aldehyde (B2) is benzaldehyde, although the aromatic ring can particularly preferably bear further substituents.

[0083] Aromatic, carbocyclic aldehydes (B2) are particularly well suited to solving the problem set out in the invention and are compounds of the general formula (AI) where Ra1, Ra2, and Ra3 independently represent a hydrogen atom, a hydroxyl group, a C1-C6 alkoxy group, a C1-C6 alkyl group, a halogen atom, a C1-C6 dialkylamino group, a di(C2-C6 hydroxyalkyl)amino group, a di(C1-C6 alkoxy-C1-C6 alkyl)amino group, a C1-C6 hydroxyalkyloxy group, a sulfonyl group, a carboxyl group, a sulfonic acid group, a sulfonamido group, a sulfonamide group, a carbamoyl group, a C2-C6 acyl group, an acetyl group, or a nitro group. Alternatively, Ra1 and Ra2, together with the carbon atoms of the benzene ring to which they are bonded, can form a saturated or unsaturated, 5-membered or 6-membered heterocyclic or carbocyclic ring. form, and Z stands for a direct bond or a vinyl group.

[0084] In a further particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) contains at least one aromatic, carbocyclic aldehyde (B2) of the general formula (AI), where Ra1, Ra2, Ra3 independently represent a hydrogen atom, a hydroxy group, a C1-C6 alkoxy group, a C1-C6 alkyl group, a halogen atom, a C1-C6 dialkylamino group, a di(C2-C6 hydroxyalkyl)amino group, a di(C1-C6 alkoxy-C1-C6 alkyl)amino group, a C1-C6 hydroxyalkyloxy group, a sulfonyl group, a carboxyl group, a sulfonic acid group, a sulfonamido group, a sulfonamide group, a carbamoyl group, a C2-C6 acyl group, an acetyl group, or a nitro group. Alternatively, Ra1 and Ra2, together with the carbon atoms of the benzene ring to which they are bonded, can form a saturated or unsaturated, 5-membered or 6-membered heterocyclic or carbocyclic ring. form, and Z stands for a direct bond or a vinyl group.

[0085] In this context, the substituents Ra1, Ra2, Ra3 and Z are selected such that the resulting aldehyde has between 7 and 20 carbon atoms.

[0086] When specific aldehydes (B2) of the general formula (AI) were used, they were particularly effective at reducing the polymerization rate of the organic C1-C6 alkoxy silanes (A21) and (A22). Therefore, when using these particularly favored aldehydes (B2), dyes were obtained that were characterized by exceptionally high color intensity, uniformity, rub fastness, and wash fastness.

[0087] Particularly preferred aldehydes of the general formula (AI) can be selected from the group consisting of benzaldehyde and its derivatives, naphthaldehyde and its derivatives, cinnamaldehyde and its derivatives.

[0090] By selecting the appropriate amounts of aldehydes (B2) used, the rate of film formation originating from the C1-C6 alkoxy silanes can be significantly influenced. For this reason, it has proven particularly advantageous to use one or more aldehydes (B2) in very specific quantity ranges.

[0091] It is particularly preferred if the second composition (B) - based on the total weight of the composition (B) - contains one or more aromatic or aliphatic aldehydes having 2 to 20 carbon atoms (B2) in a total amount of 0.1 to 50.0 wt.%, preferably 0.5 to 10.0 wt.%, more preferably 0.7 to 7.0 wt.% and most preferably 1.0 to 4.0 wt.%.

[0092] In a further particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) - based on the total weight of the composition (B) - contains one or more aromatic or aliphatic aldehydes with 2 to 20 carbon atoms (B2) in a total amount of 0.1 to 50.0 wt.%, preferably 0.5 to 10.0 wt.%, more preferably 0.7 to 7.0 wt.% and most preferably 1.0 to 4.0 wt.%.

[0093] In particular, it is especially preferred if the second composition (B) - based on the total weight of the composition (B) - contains one or more aldehydes (B2) of the general formula (AI) in a total amount of 0.1 to 50.0 wt.%, preferably 0.5 to 10.0 wt.%, more preferably 0.7 to 7.0 wt.% and most preferably 1.0 to 4.0 wt.%.

[0094] The very best results with regard to color intensity, wash fastness, and rub fastness of the dyes achievable with the process according to the invention were obtained when the composition (B) contained vanillin (B2). The use of vanillin as an aldehyde (B2) is therefore most preferred.

[0095] In a further particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) contains 0.1 to 50.0 wt.%, preferably 0.5 to 10.0 wt.%, more preferably 0.7 to 7.0 wt.% and most preferably 1.0 to 4.0 wt.% vanillin (B2) based on the total weight of the composition (B).

[0096] Vanillin, like the other aldehydes mentioned, is commercially available from common chemical suppliers known to those skilled in the art, such as Sigma-Aldrich, Fluka, or Merck. For example, vanillin with CAS number 121-33-5 can be obtained commercially from Sigma-Aldrich in various container sizes. Fat components in the composition (B)

[0097] To adjust the viscosity or to further improve the application-related properties, the composition (B) may optionally also contain at least one additional fat component.

[0098] The fatty components are hydrophobic substances that can form emulsions in the presence of water, creating micelle systems. While not definitively committing to this theory, it is hypothesized that the C1-C6 alkoxysilanes—either in the form of their monomers or, if applicable, their condensed oligomers—become embedded in this hydrophobic environment or in the micelle systems, thus altering the polarity of their surroundings. Due to the hydrophobic nature of the fatty components, the environment of the C1-C6 alkoxysilanes also becomes hydrophobic. It is assumed that the polymerization reaction of the C1-C6 alkoxysilanes leading to the film or coating proceeds at a reduced rate in this environment of decreased polarity.

[0099] For the purposes of this invention, "fatty components" are defined as organic compounds with a solubility in water at room temperature (22 °C) and atmospheric pressure (760 mmHg) of less than 1 wt.%, preferably less than 0.1 wt.%. The definition of fatty components explicitly includes only uncharged (i.e., non-ionic) compounds. Fatty components possess at least one saturated or unsaturated alkyl group with at least 12 carbon atoms.

[0100] The molecular weight of the fat components is a maximum of 5000 g / mol, preferably a maximum of 2500 g / mol, and particularly preferably a maximum of 1000 g / mol. The fat components are neither polyoxyalkylated nor polyglycerylated compounds.

[0101] The fatty components (B2) contained in the composition (B) are particularly preferred, selected from the group of C 12 -C 30 fatty alcohols, C 12 -C 30 fatty acid triglycerides, C 12 -C 30 fatty acid monoglycerides, C 12 -C 30 fatty acid diglycerides and / or hydrocarbons.

[0102] Particularly preferred fat components in this context are those from the group consisting of C12-C30 fatty alcohols, C12-C30 fatty acid triglycerides, C12-C30 fatty acid monoglycerides, C12-C30 fatty acid diglycerides, and / or hydrocarbons. For the purposes of the present invention, only nonionic substances are explicitly considered fat components. Charged compounds such as fatty acids and their salts are not considered fat components.

[0103] C12-C30 fatty alcohols can be saturated, mono- or polyunsaturated, linear or branched fatty alcohols with 12 to 30 carbon atoms.

[0104] Examples of preferred linear saturated C12-C30 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), arachiyl alcohol (eicosan-1-ol), heneicosyl alcohol (heneicosan-1-ol) and / or behenyl alcohol (docosan-1-ol).

[0105] Preferred linear unsaturated fatty alcohols are (9Z)-Octadec-9-en-1-ol (oleyl alcohol), (9E)-Octadec-9-en-1-ol (elaidyl alcohol), (9 Z 12 Z )-Octadeca-9,12-dien-1-ol (linoleyl alcohol), (9 Z 12 Z 15 Z )-Octadeca-9,12,15-trien-1-ol (linolenoyl alcohol), gadoleyl alcohol ((9 Z )-Eicos-9-en-1-ol), arachidone alcohol ((5 Z8 Z ,11 Z 14 Z )-Eicosa-5,8,11,14-tetraen-1-ol), erucyl alcohol ((13 Z )-Docos-13-en-1-ol) and / or brassidyl alcohol ((13 E )-Docosen-1-ol).

[0106] The preferred representatives for branched fatty alcohols are 2-octyl-dodecanol, 2-hexyl-dodecanol and / or 2-butyl-dodecanol.

[0107] By selecting particularly suitable fat components, the polarity of the composition (B) can be optimally adjusted and the polymerization rate of the C 1 -C 6 -alkoxysilanes can be particularly well adapted to the respective application conditions chosen.

[0108] In this context, it has been shown that in particular the use of at least one C 12 -C 30 fatty alcohol (B2) in composition (B) creates an emulsion system in which the alkoxysilanes (A21) and (A22) can be embedded particularly well.

[0109] In one embodiment, particularly good results were obtained when the second composition (B) contained one or more C12-C30 fatty alcohols 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), arachidyl alcohol (eicosan-1-ol), heneicosyl alcohol (heneicosan-1-ol), behenyl alcohol (docosan-1-ol), (9 Z )-Octadec-9-en-1-ol (oleyl alcohol), (9 E )-Octadec-9-en-1-ol (elaidyl alcohol), (9 Z 12 Z )-Octadeca-9,12-dien-1-ol (linoleyl alcohol), (9 Z 12 Z 15 Z )-Octadeca-9,12,15-trien-1-ol (linolenoyl alcohol), gadoleyl alcohol ((9 Z )-Eicos-9-en-1-ol), arachidone alcohol ((5 Z 8 Z ,11 Z 14 Z )-Eicosa-5,8,11,14-tetraen-1-ol), erucyl alcohol ((13 Z)-Docos-13-en-1-ol), brassidyl alcohol ((13 E )-Docosen-1-ol) contains 2-octyl-dodecanol, 2-hexyl-dodecanol and / or 2-butyl-dodecanol.

[0110] In a particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) comprises one or more C 12 -C 30 fatty alcohols (B2) 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), (9 Z )-Octadec-9-en-1-ol (oleyl alcohol), (9 E )-Octadec-9-en-1-ol (elaidyl alcohol), (9 Z 12 Z )-Octadeca-9,12-dien-1-ol (linoleyl alcohol), (9 Z 12 Z 15 Z)-Octadeca-9,12,15-trien-1-ol (linolenoyl alcohol), gadoleyl alcohol ((9 Z )-Eicos-9-en-1-ol), arachidone alcohol ((5 Z 8 Z ,11 Z 14 Z )-Eicosa-5,8,11,14-tetraen-1-ol), erucyl alcohol ((13 Z )-Docos-13-en-1-ol), brassidyl alcohol ((13 E )-Docosen-1-ol), 2-octyl-dodecanol, 2-hexyl-dodecanol and / or 2-butyl-dodecanol.

[0111] By selecting the appropriate amounts of C12-C30 fatty alcohols (B2) used, the rate of film formation originating from the C1-C6 alkoxy silanes can be significantly influenced. For this reason, it has proven particularly advantageous to use one or more C12-C30 fatty alcohols (B2) in very specific quantity ranges.

[0112] It is particularly preferred if the second composition (B) - based on the total weight of the composition (B) - contains one or more C 12 -C 30 fatty alcohols (B2) in a total amount of 2.0 to 50.0 wt.%, preferably 4.0 to 40.0 wt.%, further preferably 6.0 to 30.0 wt.%, even more preferably 8.0 to 20.0 wt.% and most preferably 10.0 to 15.0 wt.%.

[0113] In a further particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) - based on the total weight of the composition (B) - contains one or more C 12 -C 30 fatty alcohols (B2) in a total amount of 2.0 to 50.0 wt.%, preferably 4.0 to 40.0 wt.%, more preferably 6.0 to 30.0 wt.%, even more preferably 8.0 to 20.0 wt.% and most preferably 10.0 to 15.0 wt.%.

[0114] Furthermore, as a particularly preferred fatty component (B2), the composition (B) can also contain at least one C12-C30 fatty acid triglyceride, one C12-C30 fatty acid monoglyceride, and / or one C12-C30 fatty acid diglyceride. For the purposes of the present invention, a C12-C30 fatty acid triglyceride is understood to be the triester of the trihydric alcohol glycerol with three equivalents of fatty acid. Both structurally identical and different fatty acids within a triglyceride molecule can participate in the esterification.

[0115] According to the invention, fatty acids are understood to be saturated or unsaturated, unbranched or branched, unsubstituted or substituted C12-C30 carboxylic acids. Unsaturated fatty acids can be monounsaturated or polyunsaturated. In an unsaturated fatty acid, its C12-C30 double bond(s) can have a cis or trans configuration.

[0116] Fatty acid triglycerides are characterized by their particular suitability, in which at least one of the ester groups starting from glycerol is formed with a fatty acid selected from dodecanoic acid (lauric acid), tetradecanoic acid (myristic acid), hexadecanoic acid (palmitic acid), tetracosanoic acid (lignoceric acid), octadecanoic acid (stearic acid), eicosanoic acid (arachidic acid), docosanoic acid (behenic acid), petroselinic acid [(Z)-6-octadecenoic acid], palmitoleic acid [(9Z)-hexadec-9-enoic acid], oleic acid [(9Z)-octadec-9-enoic acid], elaidic acid [(9E)-octadec-9-enoic acid], erucic acid [(13Z)-docos-13-enoic acid], linoleic acid [(9Z, 12Z)-octadeca-9,12-dienoic acid, linolenic acid [(9Z,12Z,15Z)-Octadeca-9,12,15-trienic acid, Elaeostearinic acid [(9Z,11E,13E)-Octadeca-9,11,3-trienic acid], Arachidonic acid [(5Z,8Z,11Z,14Z)-Icosa-5,8,11,14-tetraenic acid] and / or Nervonic acid [(15Z)-Tetracos-15-enoic acid].

[0117] The fatty acid triglycerides can also be of natural origin. The fatty acid triglycerides or mixtures thereof occurring in soybean oil, peanut oil, olive oil, sunflower oil, macadamia nut oil, moringa oil, apricot kernel oil, marula oil and / or optionally hydrogenated castor oil are particularly suitable for use in the product according to the invention.

[0118] A C12-C30 fatty acid monoglyceride is defined as the monoester of the trihydric alcohol glycerol with one equivalent of fatty acid. Either the central hydroxyl group of glycerol or the terminal hydroxyl group of glycerol can be esterified with the fatty acid.

[0119] C12-C30 fatty acid monoglycerides are characterized by their particular suitability, in which a hydroxyl group of the glycerol is esterified with a fatty acid, the fatty acids being selected from dodecanoic acid (lauric acid), tetradecanoic acid (myristic acid), hexadecanoic acid (palmitic acid), tetracosanoic acid (lignoceric acid), octadecanoic acid (stearic acid), eicosanoic acid (arachidic acid), docosanoic acid (behenic acid), petroselinic acid [(Z)-6-octadecenoic acid], palmitoleic acid [(9Z)-hexadec-9-enoic acid], oleic acid [(9Z)-octadec-9-enoic acid], elaidic acid [(9E)-octadec-9-enoic acid], erucic acid [(13Z)-docos-13-enoic acid], linoleic acid [(9Z, 12Z)-Octadeca-9,12-dienoic acid, linolenic acid [(9Z,12Z,15Z)-Octadeca-9,12,15-trienoic acid, elaeostearinic acid [(9Z,11E,13E)-Octadeca-9,11,3-trienoic acid], arachidonic acid [(5Z,8Z,11Z,14Z)-Icosa-5,8,11,14-tetraenoic acid] or nervonic acid [(15Z)-Tetracos-15-enoic acid].

[0120] A C12-C30 fatty acid diglyceride is defined as the diester of the trihydric alcohol glycerol with two equivalents of fatty acid. Either the central and one terminal hydroxyl group of the glycerol can be esterified with two equivalents of fatty acid, or both terminal hydroxyl groups of the glycerol can be esterified with one fatty acid each. The glycerol can be esterified with either two structurally identical or two different fatty acids.

[0121] Fatty acid diglycerides are characterized by their particular suitability, in which at least one of the ester groups starting from glycerol is formed with a fatty acid selected from dodecanoic acid (lauric acid), tetradecanoic acid (myristic acid), hexadecanoic acid (palmitic acid), tetracosanoic acid (lignoceric acid), octadecanoic acid (stearic acid), eicosanoic acid (arachidic acid), docosanoic acid (behenic acid), petroselinic acid [(Z)-6-octadecenoic acid], palmitoleic acid [(9Z)-hexadec-9-enoic acid], oleic acid [(9Z)-octadec-9-enoic acid], elaidic acid [(9E)-octadec-9-enoic acid], erucic acid [(13Z)-docos-13-enoic acid], linoleic acid [(9Z, 12Z)-octadeca-9,12-dienoic acid, linolenic acid [(9Z,12Z,15Z)-Octadeca-9,12,15-trienic acid, Elaeostearinic acid [(9Z,11E,13E)-Octadeca-9,11,3-trienic acid], Arachidonic acid [(5Z,8Z,11Z,14Z)-Icosa-5,8,11,14-tetraenic acid] and / or Nervonic acid [(15Z)-Tetracos-15-enoic acid].

[0122] Particularly good results were obtained when composition (B) contained at least one C12-C30 fatty acid monoglyceride selected from the monoesters of glycerol with one equivalent fatty acid from the group consisting of dodecanoic acid (lauric acid), tetradecanoic acid (myristic acid), hexadecanoic acid (palmitic acid), tetracosanoic acid (lignoceric acid), octadecanoic acid (stearic acid), eicosanoic acid (arachidic acid), docosanoic acid (behenic acid), petroselinic acid [(Z)-6-octadecenoic acid], palmitoleic acid [(9Z)-hexadec-9-enoic acid], oleic acid [(9Z)-octadec-9-enoic acid], elaidic acid [(9E)-octadec-9-enoic acid], erucic acid [(13Z)-docos-13-enoic acid], linoleic acid [(9Z, 12Z)-Octadeca-9,12-dienoic acid, linolenic acid [(9Z,12Z,15Z)-Octadeca-9,12,15-trienoic acid, elaeostearinic acid [(9Z,11E,13E)-Octadeca-9,11,3-trienoic acid], arachidonic acid [(5Z,8Z,11Z,14Z)-Icosa-5,8,11,14-tetraenoic acid] and / or nervonic acid [(15Z)-tetracos-15-enoic acid].

[0123] In a particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) contains at least one C 12 -C 30 fatty acid monoglyceride (B2) which is selected from the monoesters of glycerol with one equivalent fatty acid from the group consisting of dodecanoic acid, tetradecanoic acid, hexadecanoic acid, tetracosanoic acid, octadecanoic acid, eicosanoic acid and / or docosanoic acid.

[0124] The rate of film formation originating from the C1-C6 alkoxy silanes can also be significantly influenced by selecting appropriate amounts of C12-C30 fatty acid mono-, C12-C30 fatty acid di-, and / or C12-C30 fatty acid triglycerides. For this reason, it has proven particularly advantageous to incorporate one or more C12-C30 fatty acid mono-, C12-C30 fatty acid di-, and / or C12-C30 fatty acid triglycerides (B2) in very specific quantity ranges in composition (B).

[0125] With regard to solving the problem set out in the invention, it has proven to be particularly advantageous if the second composition (B) – based on the total weight of the composition (B) – contained one or more C 12-C 30 fatty acid mono-, C 12-C 30 fatty acid di- and / or C 12-C 30 fatty acid triglycerides (B2) in a total amount of 0.1 to 20.0 wt.%, preferably 0.3 to 15.0 wt.%, more preferably 0.5 to 10.0 wt.% and most preferably 0.8 to 5.0 wt.%.

[0126] In a particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) - based on the total weight of the composition (B) - contains one or more C 12 -C 30 fatty acid mono-, C 12 -C 30 fatty acid di- and / or C 12 -C 30 fatty acid triglycerides (B2) in a total amount of 0.1 to 20.0 wt.%, preferably 0.3 to 15.0 wt.%, more preferably 0.5 to 10.0 wt.% and most preferably 0.8 to 5.0 wt.%.

[0127] The C12-C30 fatty acid mono-, C12-C30 fatty acid di- and / or C12-C30 fatty acid triglycerides can be used as the sole fat components (B2) in the compositions (B). However, it is particularly preferred to incorporate at least one C12-C30 fatty acid mono-, C12-C30 fatty acid di- and / or C12-C30 fatty acid triglyceride in combination with at least one C12-C30 fatty alcohol into the composition (B).

[0128] Furthermore, as a particularly preferred fat component (B2), the composition (B) may also contain at least one hydrocarbon.

[0129] Hydrocarbons are compounds consisting exclusively of carbon and hydrogen atoms, with 8 to 80 carbon atoms. Particularly preferred in this context are aliphatic hydrocarbons such as mineral oils, liquid paraffin oils (e.g., paraffinum liquidum or paraffinum perliquidum), isoparaffin oils, semi-solid paraffin oils, paraffin waxes, hard paraffin (paraffinum solidum), petrolatum, and polydecenes.

[0130] Liquid paraffin oils (paraffinum liquidum and paraffinum perliquidum) have proven particularly suitable in this context. Paraffinum liquidum, also known as white oil, is especially preferred as the hydrocarbon. Paraffinum liquidum is a mixture of purified, saturated, aliphatic hydrocarbons, consisting largely of hydrocarbon chains with a carbon chain distribution of 25 to 35 carbon atoms.

[0131] Particularly good results were obtained when the composition (B) contained at least one hydrocarbon (B2) selected from the group of mineral oils, liquid paraffin oils, isoparaffin oils, semi-solid paraffin oils, paraffin waxes, hard paraffin (Paraffinum Solidum), petrolatum and polydecenes.

[0132] In a particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) contains at least one fatty component (B2) from the group of hydrocarbons.

[0133] The rate of film formation originating from the C1-C6 alkoxysilanes can also be significantly influenced by selecting appropriate amounts of hydrocarbons. For this reason, it has proven particularly advantageous to use one or more hydrocarbons in very specific quantity ranges in composition (B).

[0134] With regard to solving the problem according to the invention, it has proven to be particularly advantageous if the second composition (B) - based on the total weight of the composition (B) - contained one or more hydrocarbons (B2) in a total amount of 0.5 to 20.0 wt.%, preferably 1.0 to 15.0 wt.%, more preferably 1.5 to 10.0 wt.% and most preferably 2.0 to 8.0 wt.%.

[0135] In a particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) - based on the total weight of the composition (B) - contains one or more hydrocarbons (B2) in a total amount of 0.5 to 20.0 wt.%, preferably 1.0 to 15.0 wt.%, more preferably 1.5 to 10.0 wt.% and most preferably 2.0 to 8.0 wt.%.

[0136] The hydrocarbon(s) can be used as the sole fat component (B2) in the compositions (B). However, it is particularly preferred to incorporate at least one hydrocarbon in combination with at least one other component into the compositions (B).

[0137] The composition (B) most preferably contains at least one fatty component (B2) from the group of C 12 -C 30 fatty alcohols and at least one further fatty component from the group of hydrocarbons. Surfactants in composition (B)

[0138] Due to its water (B1) and, if present, fat (B2) content, composition (B) can exist in the form of an emulsion. To further optimize the formation of the emulsion, it has proven particularly advantageous to include at least one surfactant in composition (B).

[0139] The composition (B) is therefore particularly preferably to contain at least one additional surfactant.

[0140] In a further particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) contains at least one surfactant.

[0141] The term surfactants (T) refers to surface-active substances that form adsorption layers on surfaces and interfaces or can aggregate in bulk phases to form micelle colloids or lyotropic mesophases. A distinction is made between anionic surfactants, consisting of a hydrophobic residue and a negatively charged hydrophilic head group; amphoteric surfactants, which carry both a negative and a compensating positive charge; cationic surfactants, which have a hydrophobic residue and a positively charged hydrophilic group; and nonionic surfactants, which have no charges but strong dipole moments and are highly hydrated in aqueous solution.

[0142] In a particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) contains at least one non-ionic surfactant.

[0143] Non-ionic surfactants contain, for example, a polyol group, a polyalkylene glycol ether group, or a combination of polyol and polyglycol ether groups as their hydrophilic group. Examples of such compounds are... Addition products of 2 to 50 mol of ethylene oxide and / or 0 to 5 mol of propylene oxide to linear and branched fatty alcohols with 6 to 30 carbon atoms, the fatty alcohol polyglycol ethers or the fatty alcohol polypropylene glycol ethers or mixed fatty alcohol polyethers; addition products of 2 to 50 mol of ethylene oxide and / or 0 to 5 mol of propylene oxide to linear and branched fatty acids with 6 to 30 carbon atoms, the fatty acid polyglycol ethers or the fatty acid polypropylene glycol ethers or mixed fatty acid polyethers; addition products of 2 to 50 mol of ethylene oxide and / or 0 to 5 mol of propylene oxide to linear and branched alkylphenols with 8 to 15 carbon atoms in the alkyl group, the alkylphenol polyglycol ethers or the alkyl polypropylene glycol ethers, or mixed alkylphenol polyethers. End-group sealed addition products of 2 to 50 mol ethylene oxide and / or 0 to 5 mol propylene oxide to linear and branched fatty alcohols with 8 to 30 carbon atoms, with a methyl or C2-C6 alkyl group,fatty acids with 8 to 30 carbon atoms and alkylphenols with 8 to 15 carbon atoms in the alkyl group, such as the types available under the trade names Dehydol® LS, Dehydol® LT (Cognis), C12-C30 fatty acid mono- and diesters of adsorption products of 1 to 30 mol of ethylene oxide to glycerol, adsorption products of 5 to 60 mol of ethylene oxide to castor oil and hydrogenated castor oil, polyol fatty acid esters, such as the trade product Hydagen® HSP (Cognis) or Sovermol® types (Cognis), alkoxylated triglycerides, alkoxylated fatty acid alkyl esters of the formula (Tnio-1) R1 CO-(OCH2 CHR2) w OR3 (Tnio-1) in the R1 CO represents a linear or branched, saturated and / or unsaturated acyl group with 6 to 22 carbon atoms, R 2< represents hydrogen or methyl, R 3< represents linear or branched alkyl groups with 1 to 4 carbon atoms, and w represents numbers from 1 to 20. Examples include amine oxides and hydroxyl mixed ethers.as described, for example, in DE-OS 19738866, sorbitan fatty acid esters and adsorption products of ethylene oxide to sorbitan fatty acid esters such as polysorbates, sugar fatty acid esters and adsorption products of ethylene oxide to sugar fatty acid esters, adsorption products of ethylene oxide to fatty acid alkanolamides and fatty amines, sugar surfactants of the type of alkyl and alkenyl oligoglycosides according to formula (E4-II), R 4< O-[G] p (Tnio-2) where R 4< represents an alkyl or alkenyl residue with 4 to 22 carbon atoms, G represents a sugar residue with 5 or 6 carbon atoms, and p represents numbers from 1 to 10. They can be obtained according to the relevant methods of preparative organic chemistry. The alkyl and alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably from glucose,The preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglycosides. The index p in the general formula (Tnio-2) indicates the degree of oligomerization (DP), i.e., the distribution of mono- and oligoglycosides, and represents a number between 1 and 10. While p in a single molecule must always be an integer and can primarily take the values ​​p = 1 to 6, the value p for a specific alkyl oligoglycoside is an analytically determined calculated quantity, which usually represents a fraction. Preferably, alkyl and / or alkenyl oligoglycosides with a mean degree of oligomerization p of 1.1 to 3.0 are used. From an application-related point of view, those alkyl and / or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and, in particular, between 1.2 and 1.4 are preferred. The alkyl or alkenyl residue R 4< can differ from primary alcohols with 4 to 11,preferably derived from 8 to 10 carbon atoms. Typical examples are butanol, capron alcohol, caprylic alcohol, capric alcohol, and undecyl alcohol, as well as their technical mixtures, such as those obtained, for example, during the hydrogenation of technical fatty acid methyl esters or during the hydrogenation of aldehydes from Roelen's oxo synthesis. Alkyl oligoglucosides of chain length C8-C10 (DP = 1 to 3), which are obtained as foreshots during the distillative separation of technical C8-C18 coconut fatty alcohol and may be contaminated with less than 6 wt% C12 alcohol, as well as alkyl oligoglucosides based on technical C9 / 11 oxo alcohols (DP = 1 to 3), are preferred. The alkyl or alkenyl group R 15< can also be derived from primary alcohols with 12 to 22, preferably 12 to 14 carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, and oleyl alcohol.Elaidyl alcohol, petroselinyl alcohol, arachiyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol, and their technical mixtures, which can be obtained as described above. Preferably, alkyl oligoglucosides based on hydrogenated C12 / 14 coconut alcohol with a DP of 1 to 3 are used. Sugar surfactants of the fatty acid N-alkyl polyhydroxyalkylamide type, a nonionic surfactant of the formula (Tnio-3), R5<CO-NR6<-[Z] (Tnio-3) in which R5<CO represents an aliphatic acyl group with 6 to 22 carbon atoms, R6< represents hydrogen, an alkyl or hydroxyalkyl group with 1 to 4 carbon atoms, and [Z] represents a linear or branched polyhydroxyalkyl group with 3 to 12 carbon atoms and 3 to 10 hydroxyl groups. Fatty acid N-alkylpolyhydroxyalkylamides are well-known substances that are usually produced by reductive amination of a reducing sugar with ammonia,Fatty acid N-alkylpolyhydroxyalkylamides can be obtained by reacting an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester, or a fatty acid chloride. Preferably, the fatty acid N-alkylpolyhydroxyalkylamides are derived from reducing sugars with 5 or 6 carbon atoms, in particular from glucose. The preferred fatty acid N-alkylpolyhydroxyalkylamides are therefore fatty acid N-alkylglucamides, as represented by the formula (Tnio-4): R 7< CO-(NR 8< ) -CH 2 - [CH(OH)] 4 - CH 2 OH (Tnio-4). Preferably, the fatty acid N-alkylpolyhydroxyalkylamides used are glucamides of the formula (Tnio-4), in which R 8< represents hydrogen or an alkyl group and R 7< CO represents the acyl group of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, arachidic acid, gadoleic acid.Behenic acid or erucic acid, or their technical mixtures, are preferred. Particularly preferred are fatty acid N-alkylglucamides of the formula (Tnio-4), which are obtained by reductive amination of glucose with methylamine and subsequent acylation with lauric acid or C12 / 14 coconut fatty acid, or a corresponding derivative. Furthermore, the polyhydroxyalkylamides can also be derived from maltose and palatinose.

[0144] The sugar surfactants in the compositions used according to the invention may preferably be present in amounts of 0.1–20% by weight, based on the total composition. Amounts of 0.5–15% by weight are preferred, and amounts of 0.5–7.5% by weight are particularly preferred.

[0145] Other typical examples of non-ionic surfactants are fatty acid amide polyglycol ethers, fatty amine polyglycol ethers, mixed ethers or mixed formals, protein hydrolysates (especially plant-based products based on wheat) and polysorbates.

[0146] Preferred non-ionic surfactants include alkylene oxide adsorption products to saturated linear fatty alcohols and fatty acids, each containing 2 to 30 moles of ethylene oxide per mole of fatty alcohol or fatty acid, as well as sugar surfactants. Preparations with excellent properties are also obtained when they contain fatty acid esters of ethoxylated glycerol as non-ionic surfactants.

[0147] These compounds are characterized by the following parameters. The alkyl group R contains 6 to 22 carbon atoms and can be either linear or branched. Primary linear groups and 2-methyl-branched aliphatic groups are preferred. Examples of such alkyl groups are 1-octyl, 1-decyl, 1-lauryl, 1-myristyl, 1-cetyl, and 1-stearyl. 1-Octyl, 1-decyl, 1-lauryl, and 1-myristyl are particularly preferred. When using so-called "oxo alcohols" as starting materials, compounds with an odd number of carbon atoms in the alkyl chain predominate.

[0148] The compounds with alkyl groups used as surfactants can each be a single, homogeneous substance. However, it is generally preferred to start with native plant or animal raw materials for their production, resulting in mixtures of substances with varying alkyl chain lengths, depending on the specific raw material.

[0149] For surfactants that represent addition products of ethylene and / or propylene oxide to fatty alcohols or derivatives of these addition products, both products with a "normal" homolog distribution and those with a narrowed homolog distribution can be used. A "normal" homolog distribution refers to mixtures of homologs obtained from the reaction of fatty alcohol and alkylene oxide using alkali metals, alkali metal hydroxides, or alkali metal alkoxides as catalysts. Narrowed homolog distributions, on the other hand, are obtained when, for example, hydrotalcites, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides, or alkoxides are used as catalysts. The use of products with a narrowed homolog distribution may be preferable.

[0150] Particularly good results were obtained when a second composition (B) was used in the process according to the invention, which contained at least one ethoxylated fatty alcohol with a degree of ethoxylation of 80 to 120.

[0151] In a further particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) contains at least one non-ionic surfactant of formula (TI), wherein Ra represents a saturated or unsaturated, unbranched or branched C 8 -C 24 alkyl group, preferably a saturated, unbranched C 16 - to C 18 alkyl group, and n represents an integer from 80 to 120, preferably an integer from 90 to 110 and particularly preferably the number 100.

[0152] A particularly suitable non-ionic surfactant of this type bears the trade name Brij S 100 or Brij S 100 PA SG. This is stearyl alcohol ethoxylated with 100 EO, which is commercially available from the company Croda and has the CAS number 9005-00-9.

[0153] Particularly good results were obtained when a second composition (B) was used in the process according to the invention, which contained at least one ethoxylated fatty alcohol with a degree of ethoxylation of 10 to 40.

[0154] In a further particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) contains at least one non-ionic surfactant of formula (T-II), wherein Rb represents a saturated or unsaturated, unbranched or branched C 8 -C 24 alkyl group, preferably a saturated, unbranched C 16 - to C 18 alkyl group, and m represents an integer from 10 to 40, preferably an integer from 20 to 35 and particularly preferably the number 30.

[0155] One particularly suitable nonionic surfactant of this type is ceteareth-30. Ceteareth-30 is a mixture of cetyl alcohol and stearyl alcohol, each ethoxylated with 30 units of ethylene oxide. This mixture of cetyl alcohol and stearyl alcohol is referred to as cetearyl alcohol. Ceteareth-30 has the CAS number 68439-49-6 and is available, for example, from BASF under the trade name Eumulgin B3.

[0156] It has proven to be particularly advantageous if the composition (B) contains at least one non-ionic surfactant of formula (TI) as well as at least one non-ionic surfactant of formula (T-II). Polymers in composition (B)

[0157] In a further embodiment, the composition (B) used in the inventive method can also be formulated in the form of a water-containing gel.

[0158] As a further optional component, composition (B) may therefore also contain at least one polymer, particularly preferably a thickening polymer.

[0159] Suitable polymers in this context include, for example: Vinylpyrrolidone / vinyl ester copolymers, such as those marketed under the trademark Luviskol®< (BASF). Luviskol®< VA 64 and Luviskol®< VA 73, both vinylpyrrolidone / vinyl acetate copolymers, are also preferred nonionic polymers. Cellulose ethers, such as hydroxypropylcellulose, hydroxyethylcellulose, and methylhydroxypropylcellulose, such as those marketed under the trademarks Culminal®< and Benecel®< (AQUALON) and Natrosol®< types (Hercules). Starch and its derivatives, especially starch ethers, for example Structure®< XL (National Starch), a multifunctional, salt-tolerant starch; shellac polyvinylpyrrolidones, such as those marketed under the name Luviskol®< (BASF).

[0160] The polymers are preferably present in composition (B) in amounts of 0.05 to 10 wt.%, based on the total composition. Amounts of 0.1 to 5 wt.% are particularly preferred.

[0161] In a further particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) contains at least one thickening polymer, preferably at least one cellulose ether selected from the group consisting of hydroxyethylcellulose, hydroxypropylcellulose and methylhydroxypropylcellulose. Solvent in composition (B)

[0162] Further work leading to this invention has shown that the use of at least one protic solvent in composition (B) can also reduce the reaction rate of the C1-C6 alkoxysilanes upon contact with composition (A). For this reason, at least one additional solvent can be added to composition (B).

[0163] Protic solvents possess at least one hydroxyl group. While not definitively stating this theory, it is hypothesized that solvents can also react with C1-C6 alkoxysilanes via their hydroxyl group(s), but that the reaction between solvent and C1-C6 alkoxysilanes proceeds more slowly than the analogous reaction between water and C1-C6 alkoxysilanes. Overall, this reduces the hydrolysis and / or condensation reactions of the C1-C6 alkoxysilanes.

[0164] Suitable solvents include, for example, 1,2-propylene glycol, 1,3-propylene glycol, ethylene glycol, 1,2-butylene glycol, dipropylene glycol, ethanol, isopropanol, diethylene glycol monoethyl ether, glycerin, phenoxyethanol and / or benzyl alcohol.

[0165] In a further particularly preferred embodiment, a process according to the invention is characterized in that the second composition (B) contains at least one solvent 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, glycerin, phenoxyethanol and / or benzyl alcohol.

[0166] Compositions (B) containing 1,2-propylene glycol as a solvent are particularly preferred.

[0167] 1,2-Propylene glycol is also known as 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.

[0168] All of the solvents described above are commercially available from various chemical suppliers such as Aldrich or Fluka.

[0169] By using the aforementioned solvents in suitable quantities, the rate of film formation originating from the C1-C6 alkoxysilanes can be significantly influenced. For this reason, it has proven particularly advantageous to use one or more solvents in very specific quantity ranges.

[0170] It is particularly preferred if the second composition (B) - based on the total weight of the composition (B) - contains one or more solvents in a total amount of 1.0 to 35.0 wt.%, preferably 4.0 to 25.0 wt.%, more preferably 8.0 to 20.0 wt.%, and most preferably 10.0 to 15.0 wt.%.

[0171] It is particularly preferred if the second composition (B) - based on the total weight of the composition (B) - contains one or more solvents 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, glycerin, phenoxyethanol and / or benzyl alcohol in a total amount of 1.0 to 35.0 wt.%, preferably 4.0 to 25.0 wt.%, further preferably 8.0 to 20.0 wt.%, and most preferably 10.0 to 15.0 wt.%. Other cosmetic ingredients in the composition (B)

[0172] In addition to the very special preferred ingredients already described above, composition (B) may also contain one or more other cosmetic ingredients.

[0173] The cosmetic ingredients that may be optionally used in composition (B) can be any suitable components to impart further beneficial properties to the product. For example, composition (A) may contain a solvent, a thickening or film-forming polymer, a surfactant from the group of nonionic, cationic, anionic, or zwitterionic / amphoteric surfactants, coloring compounds from the group of pigments, direct dyes, oxidation dye precursors, fatty components from the group of C8-C30 fatty alcohols, hydrocarbon compounds, fatty acid esters, acids and bases belonging to the group of pH regulators, perfumes, preservatives, plant extracts, and protein hydrolysates.

[0174] If the process according to the invention is a process for coloring keratinous material, the composition (B) may very preferably contain at least one coloring compound from the group of pigments and / or direct dyes.

[0175] The selection of these additional substances will be made by a person skilled in the art according to the desired properties of the product. Regarding further optional components and the quantities of these components used, explicit reference is made to the relevant handbooks known to those skilled in the art. pH values ​​of the compositions in the process

[0176] Further experiments revealed that the pH values ​​of compositions (A) and / or (B) can influence the previously described hydrolysis and condensation reactions that occur during application. It was found that alkaline pH values, in particular, halt condensation at the oligomer stage. The more acidic the reaction mixture, the more vigorous the condensation appears to be, and the higher the molecular weight of the silane condensates formed during condensation. For this reason, it is preferred that compositions (A) and / or (B) have a pH value 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.

[0177] The water content of composition (A) is a maximum of 10.0 wt.% and is preferably set even lower. In some embodiments, the water content of composition (B) can also be chosen to be low. Particularly with compositions with very low water content, measuring the pH value using conventional methods known from the prior art (pH measurement using glass electrodes via single-rod measuring chains or via pH indicator paper) can prove difficult. For this reason, the pH values ​​according to the invention are those obtained after mixing or diluting the preparation in a 1:1 weight ratio with distilled water.

[0178] The corresponding pH value is measured accordingly, for example after 50 g of the composition according to the invention has been mixed with 50 g of distilled water.

[0179] In a further particularly preferred embodiment, a method according to the invention is characterized in that the composition (A) and / or (B) after dilution with distilled water in a weight ratio of 1:1 has a pH value 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.

[0180] To achieve this alkaline pH value, it may be necessary to add an alkalizing and / or acidifying agent to the reaction mixture. The pH values ​​referred to in the present invention are pH values ​​measured at a temperature of 22°C.

[0181] Examples of alkalizing agents include ammonia, alkanolamines and / or basic amino acids.

[0182] Alkanolamines can be selected from primary amines with a C2-C6 alkyl backbone bearing at least one hydroxyl group. Preferred alkanolamines are selected from the group consisting of 2-aminoethanol-1-ol (monoethanolamine), 3-aminopropan-1-ol, 4-aminobutan-1-ol, 5-aminopentan-1-ol, 1-aminopropan-2-ol, 1-aminobutan-2-ol, 1-aminopentan-2-ol, 1-aminopentan-3-ol, 1-aminopentan-4-ol, 3-amino-2-methylpropan-1-ol, 1-amino-2-methylpropan-2-ol, 3-aminopropan-1,2-diol, and 2-amino-2-methylpropan-1,3-diol.

[0183] For the purposes of this invention, an amino acid is defined as an organic compound whose structure contains at least one protonable amino group and at least one -COOH or -SO3H group. Preferred amino acids are aminocarboxylic acids, in particular α-(alpha)-aminocarboxylic acids and ω-aminocarboxylic acids, with α-aminocarboxylic acids being particularly preferred.

[0184] According to the invention, basic amino acids are understood to be those amino acids which have an isoelectric point pl of greater than 7.0.

[0185] Basic α-aminocarboxylic acids contain at least one asymmetric carbon atom. Within the scope of the present invention, both possible enantiomers can be used as specific compounds or mixtures thereof, particularly as racemates. However, it is especially advantageous to use the naturally occurring isomeric form, usually in the L-configuration.

[0186] The basic amino acids are preferably selected from the group consisting of arginine, lysine, ornithine, and histidine, particularly preferably from arginine and lysine. In a further particularly preferred embodiment, a composition according to the invention is therefore characterized in that the alkalizing agent is a basic amino acid from the group consisting of arginine, lysine, ornithine, and / or histidine.

[0187] Furthermore, inorganic alkalizing agents can also be used. 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.

[0188] Particularly preferred alkalizing agents are ammonia, 2-aminoethanol-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.

[0189] In addition to the alkalizing agents described above, those skilled in the art are familiar with common acidifying agents for fine-tuning the pH value. According to the invention, preferred acidifying agents are food acids, such as citric acid, acetic acid, malic acid, or tartaric acid, as well as diluted mineral acids. Application of compositions (A) and (B)

[0190] The process according to the invention comprises the application of compositions (A), (B), and (C) to the keratinous material. A key aspect of the process is that compositions (A) and (B) come into contact with each other on the keratinous material. As previously described, this contact can be achieved either by pre-mixing (A) and (B) or by successively applying (A) and (B) to the keratinous material. The contact between the components of (A) and (B) can thus be established in the formulation before application or occur during application on the keratinous material itself.

[0191] The work leading to this invention has shown that the composition (B) containing water (B1) and aldehydes (B2) can have an optimal influence on the low-water silane blend (i.e., on the composition (A)) particularly when the compositions (A) and (B) have been mixed together before application.

[0192] This mixing can be achieved, for example, by stirring or shaking. It is particularly advantageous to package the two compositions (A) and (B) separately in two containers, and then, before use, to transfer the entire quantity of composition (A) from its container into the container containing the second composition (B).

[0193] In a particularly preferred embodiment, a method according to the invention is characterized in that a composition is applied to the keratinous material which was produced immediately before application by mixing the first composition (A) and the second composition (B).

[0194] The two compositions (A) and (B) can be mixed together in different proportions.

[0195] Composition (A) is particularly preferably used in the form of a relatively highly concentrated, low-water silane blend, which is effectively diluted by mixing it with composition (B). For this reason, it is especially preferred to mix composition (A) with a weight excess of composition (B). 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).

[0196] In a particularly preferred embodiment, a method according to the invention is characterized in that a composition is applied to the keratinous material which was produced immediately before application by mixing the first composition (A) and the second composition (B) in a ratio (A) / (B) of 1:5 to 1:20.

[0197] In principle, it is also possible to use composition (A) in a weight excess relative to composition (B). For example, 20 parts by weight (A) can be mixed with 1 part by weight (B), or 10 parts by weight (A) can be mixed with 1 part by weight (B), or 5 parts by weight (A) can be mixed with 1 part by weight (B).

[0198] Furthermore, it is also conceivable to apply compositions (A) and (B) successively to the keratinous material, so that contact between (A) and (B) only occurs on the keratinous material. In this embodiment, preferably no washing of the keratinous material takes place between the application of compositions (A) and (B), i.e., no treatment of the keratinous material with water or water and surfactants.

[0199] The third composition (C) is a composition that contains at least one colouring compound from the group of pigments and / or direct dyes.

[0200] When using the three compositions (A), (B) and (C), various embodiments according to the invention are obtained.

[0201] In one embodiment, it is particularly preferred to prepare a mixture of the three compositions (A), (B) and (C) before application and then to apply this mixture to the keratin material.

[0202] In a particularly preferred embodiment, a method according to the invention is characterized in that a composition is applied to the keratinous material which was obtained immediately before application by mixing the first composition (A) with the second composition (B) and a third composition (C), wherein the third composition (C) contains at least one coloring compound from the group of pigments and / or direct dyes.

[0203] When coloring the keratin material, it can also be particularly advantageous to prepare a mixture immediately before application by mixing the first composition (A) and the second composition (B) and to apply this mixture of (A) and (B) to the keratin material. The third composition (C) containing the coloring compounds can then be applied to the keratin material subsequently.

[0204] In a particularly preferred embodiment, a method according to the invention is characterized in that a composition is applied to the keratinous material which was obtained immediately before application by mixing the first composition (A) with the second composition (B), and subsequently the composition (C) is applied to the keratinous material.

[0205] In other words, a particularly preferred method according to the invention is characterized in that, in a first step, a composition is applied to the keratinous material which was produced immediately before application by mixing the first composition (A) and the second composition (B), and in a second step, the further composition (C) is applied to the keratinous material.

[0206] In addition to compositions (A), (B), and (C), a further or fourth composition (D) can also be applied to the keratin material in the process according to the invention. The application of composition (D) is particularly preferably carried out in a dyeing process to further seal the previously obtained dyes. For this sealing purpose, composition (D) can, for example, contain at least one film-forming polymer.

[0207] In other words, a method according to the invention in which the following is applied to the keratinous material is particularly preferred. a further composition (D) which contains at least one film-forming polymer. Color-giving compounds

[0208] For the purposes of this invention, pigments are understood to be coloring compounds which have a solubility in water at 25 °C of less than 0.5 g / L, preferably less than 0.1 g / L, and even more preferably less than 0.05 g / L. The water solubility can be determined, for example, by the method described below: 0.5 g of the pigment is weighed into a beaker. A magnetic stir bar is added. Then one liter of distilled water is added. This mixture is heated to 25 °C for one hour while stirring on a magnetic stirrer. If undissolved components of the pigment are still visible in the mixture after this period, the solubility of the pigment is below 0.5 g / L. If the pigment-water mixture cannot be visually assessed due to the high intensity of the pigment, which may be finely dispersed, the mixture is filtered.If a proportion of undissolved pigments remains on the filter paper, the solubility of the pigment is below 0.5 g / L.

[0209] Suitable color pigments can be of inorganic and / or organic origin.

[0210] In a preferred embodiment, the agent according to the invention is characterized in that it contains at least one color-imparting compound from the group of inorganic and / or organic pigments.

[0211] Preferred color pigments are selected from synthetic or natural inorganic pigments. Inorganic color pigments of natural origin can be produced, for example, from chalk, ochre, umber, green earth, burnt sienna, or graphite. Furthermore, black pigments such as iron oxide black, colored pigments such as ultramarine or iron oxide red, as well as fluorescent or phosphorescent pigments can be used as inorganic color pigments.

[0212] Particularly suitable are colored metal oxides, hydroxides and oxide hydrates, mixed-phase pigments, sulfur-containing silicates, silicates, metal sulfides, complex metal cyanides, metal sulfates, chromates and / or molybdates. Especially preferred color pigments are black iron oxide (CI 77499), yellow iron oxide (CI 77492), red and brown iron oxide (CI 77491), manganese violet (CI 77742), ultramarine (sodium aluminum sulfosilicates, CI 77007, Pigment Blue 29), chromium oxide hydrate (CI 77289), iron blue (ferric ferrocyanide, CI 77510) and / or carmine (cochineal).

[0213] According to the invention, particularly preferred coloring compounds from the group of pigments are colored pearlescent pigments. These are typically based on mica and / or mica and can be coated with one or more metal oxides. Mica belongs to the layered silicates. The most important representatives of these silicates are muscovite, phlogopite, paragonite, biotite, lepidolite, and margarite. To produce the pearlescent pigments in combination with metal oxides, the mica, predominantly muscovite or phlogopite, is coated with a metal oxide.

[0214] In a particularly preferred embodiment, a method according to the invention is characterized in that the composition (C) contains at least one coloring compound from the group of inorganic pigments, which is selected from the group of colored metal oxides, metal hydroxides, metal oxide hydrates, silicates, metal sulfides, complex metal cyanides, metal sulfates, bronze pigments and / or colored pigments based on mica or micaceous oxide, which are coated with at least one metal oxide and / or one metal oxychloride.

[0215] As an alternative to natural mica, synthetic mica coated with one or more metal oxides can also be used as a pearlescent pigment. Particularly favored pearlescent pigments are based on natural or synthetic mica and coated with one or more of the aforementioned metal oxides. The color of the respective pigments can be varied by changing the thickness of the metal oxide layer(s).

[0216] In a further preferred embodiment, the composition (C) according to the invention is characterized in that it contains at least one coloring compound from the group of pigments selected from the group of colored metal oxides, metal hydroxides, metal oxide hydrates, silicates, metal sulfides, complex metal cyanides, metal sulfates, bronze pigments and / or from coloring compounds based on mica or micaceous oxide, which are coated with at least one metal oxide and / or one metal oxychloride.

[0217] In a further preferred embodiment, a composition (C) according to the invention is characterized in that it contains at least one coloring compound selected from mica- or micaceous-based pigments coated with one or more metal oxides from the group consisting of titanium dioxide (CI 77891), black iron oxide (CI 77499), yellow iron oxide (CI 77492), red and / or brown iron oxide (CI 77491, CI 77499), manganese violet (CI 77742), ultramarine (sodium aluminum sulfosilicates, CI 77007, Pigment Blue 29), chromium oxide hydrate (CI 77289), chromium oxide (CI 77288) and / or iron blue (ferric ferrocyanide, CI 77510).

[0222] In a further embodiment, the agent or preparation according to the invention can also contain one or more color-imparting compounds from the group of organic pigments.

[0223] The organic pigments according to the invention are correspondingly insoluble organic dyes or color lakes, which may be selected, for example, from the group of nitroso, nitro-azo, xanthene, anthraquinone, isoindolinone, isoindolin, quinacridone, perinone, perylene, diketopyrrolopyorrole, indigo, thioindido, dioxazine, and / or triarylmethane compounds.

[0224] Particularly suitable organic pigments include, for example, carmine, quinacridone, phthalocyanine, sorghum, blue pigments with the Color Index numbers CI 42090, CI 69800, CI 69825, CI 73000, CI 74100, CI 74160, yellow pigments with the Color Index numbers CI 11680, CI 11710, CI 15985, CI 19140, CI 20040, CI 21100, CI 21108, CI 47000, CI 47005, green pigments with the Color Index numbers CI 61565, CI 61570, CI 74260, orange pigments with the Color Index numbers CI 11725, CI 15510, CI 45370, CI 71105, and red pigments with the Color Index Numbers CI 12085, CI 12120, CI 12370, CI 12420, CI 12490, CI 14700, CI 15525, CI 15580, CI 15620, CI 15630, CI 15800, CI 15850, CI 15865, CI 15880, CI 17200, CI 26100, CI 45380, CI 45410, CI 58000, CI 73360, CI 73915 and / or CI 75470.

[0225] In a further particularly preferred embodiment, a method according to the invention is characterized in that the composition (C) contains at least one coloring compound from the group of organic pigments selected from the group consisting of carmine, quinacridone, phthalocyanine, sorghum, blue pigments with the color index numbers CI 42090, CI 69800, CI 69825, CI 73000, CI 74100, CI 74160, yellow pigments with the color index numbers CI 11680, CI 11710, CI 15985, CI 19140, CI 20040, CI 21100, CI 21108, CI 47000, CI 47005, green pigments with the color index numbers CI 61565, CI 61570, CI 74260, and orange pigments with the color index numbers CI 11725, CI 15510, CI 45370, CI 71105, red pigments with the color index numbers CI 12085, CI 12120, CI 12370, CI 12420, CI 12490, CI 14700, CI 15525, CI 15580, CI 15620, CI 15630, CI 15800, CI 15850, CI 15865, CI 15880, CI 17200, CI 26100, CI 45380, CI 45410, CI 58000, CI 73360, CI 73915 and / or CI 75470.

[0226] The organic pigment can also be a paint lake. For the purposes of this invention, the term "paint lake" refers to particles comprising a layer of absorbed dyes, wherein the particle-dye unit is insoluble under the aforementioned conditions. These particles can be, for example, inorganic substrates such as aluminum, silica, calcium borosilicate, calcium aluminum borosilicate, or even aluminum itself.

[0227] For example, alizarin lacquer can be used as a colored lacquer.

[0228] Due to their excellent light and temperature resistance, the use of the aforementioned pigments in the composition according to the invention is particularly preferred. Furthermore, it is preferred if the pigments used have a specific particle size. This particle size leads, on the one hand, to a uniform distribution of the pigments in the polymer film formed and, on the other hand, prevents a rough feeling on the hair or skin after application of the cosmetic composition. It is therefore advantageous according to the invention if the at least one pigment has an average particle size D50 of 1.0 to 50 µm, preferably of 5.0 to 45 µm, more preferably of 10 to 40 µm, and particularly of 14 to 30 µm. The average particle size D50 can be determined, for example, using dynamic light scattering (DLS).

[0229] Pigments with a specific shape may also have been used to color the keratin material. For example, a pigment based on a lamellar and / or lenticular substrate platelet may be used. Furthermore, coloration based on a substrate platelet containing a vacuum-metallized pigment is also possible.

[0230] The substrate platelets of this type have 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 platelets is at least 1 nm, preferably at least 2.5 nm, particularly preferably at least 5 nm, for example at least 10 nm. Preferred thickness ranges for the substrate platelets are 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 platelet has a thickness that is as uniform as possible.

[0231] Due to the thinness of the substrate platelets, the pigment has a particularly high opacity.

[0232] The substrate platelets are monolithic. In this context, monolithic means consisting of a single, closed unit without fractures, layering, or inclusions, although structural changes may occur within the substrate platelets. The substrate platelets are preferably homogeneous, meaning that no concentration gradient exists within them. In particular, the substrate platelets are not layered and do not contain any particles or other distributed particles.

[0233] The size of the substrate platelet can be tailored to the specific application, particularly the desired effect on the keratinous material. Typically, the substrate platelets have a mean maximum diameter of approximately 2 to 200 µm, especially approximately 5 to 100 µm.

[0234] In a preferred embodiment, the aspect ratio, expressed as the ratio of the mean size to the mean thickness, is at least 80, preferably at least 200, more preferably at least 500, and particularly preferably more than 750. The mean size of the uncoated substrate platelets is defined as the d50 value of the uncoated substrate platelets. Unless otherwise specified, the d50 value was determined using a Sympatec Helos instrument with Quixel wet dispersion. For sample preparation, the sample to be tested was pre-dispersed in isopropanol for 3 minutes.

[0235] The substrate plates can be made from any material that can be formed into platelet form.

[0236] They can be of natural origin or synthetically produced. Materials from which the substrate plates can be constructed include, for example, metals and metal alloys, metal oxides, preferably aluminum oxide, inorganic compounds and minerals such as mica and (semi-)precious stones, as well as plastics. Preferably, the substrate plates are composed of metal (alloys).

[0237] Any metal suitable for metallic luster pigments can be used. Such metals include iron and steel, as well as all air- and water-resistant (semi-)metals such as platinum, zinc, chromium, molybdenum, and silicon, and their alloys such as aluminum bronzes and brass. Preferred metals are aluminum, copper, silver, and gold. Preferred substrate platelets are aluminum and brass platelets, with aluminum substrate platelets being particularly preferred.

[0238] Lamellar substrate platelets are characterized by an irregularly structured edge and are also referred to as "cornflakes" due to their appearance.

[0239] Due to their irregular structure, pigments based on lamellar substrate platelets produce a high proportion of scattered light. Furthermore, these pigments do not completely mask the existing color of a keratinous material, and effects similar to natural graying can be achieved.

[0240] Lenticular (lens-shaped) substrate platelets have a generally regular, rounded edge and are also referred to as "silver dollars" due to their appearance. Because of their regular structure, pigments based on lenticular substrate platelets have a high proportion of reflected light.

[0241] Vacuum metallized pigments (vacuum metallized pigments,Vacuum metallized metal plates (VMPs) can be obtained, for example, by releasing metals, metal alloys, or metal oxides from appropriately coated foils. They are characterized by a particularly small thickness of the substrate platelets in the range of 5 to 50 nm and by a particularly smooth surface with increased reflectivity. Substrate platelets comprising a pigment metallized in a vacuum are also referred to as VMP substrate platelets within the scope of this application. Aluminum VMP substrate platelets can be obtained, for example, by releasing aluminum from metallized foils.

[0242] The substrate plates made of metal or metal alloy can be passivated, for example by anodizing (oxide layer) or chromating.

[0243] Uncoated lamellar, lenticular and / or VPM substrate plates, especially those made of metal or metal alloy, reflect the incident light to a high degree and produce a light-dark flop, but no color impression.

[0244] A color impression can be created, for example, due to optical interference effects. Such pigments can be based on substrate plates with at least a single coating. These exhibit interference effects through the superposition of differently refracted and reflected light rays.

[0245] Accordingly, preferred pigments are pigments based on a coated lamellar substrate plate. The substrate plate preferably has at least one coating B of a high-refractive-index metal oxide with a coating thickness of at least 50 nm. A further coating A is preferably located between coating B and the surface of the substrate plate. Optionally, a further coating C, different from the underlying layer B, is located on top of layer B.

[0246] Suitable materials for coatings A, B, and C include all substances that can be permanently and film-like applied to the substrate plates and, in the case of layers A and B, possess the required optical properties. Generally, coating only a portion of the substrate plate surface is sufficient to obtain a pigment with a glossy effect. For example, only the top and / or bottom surface of the substrate plates can be coated, leaving the side surface(s) uncoated. Preferably, the entire surface of the optionally passivated substrate plates, including the side surfaces, is covered by coating B. The substrate plates are thus completely encased by 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 preferably also to layer C, if present.

[0247] Although multiple coatings A, B and / or C may be present, the coated substrate plates preferably each have only one coating A, B and, if present, C.

[0248] The coating B is composed of at least one high-refractive-index metal oxide. High-refractive-index materials have a refractive index of at least 1.9, preferably at least 2.0, and particularly preferably at least 2.4. Preferably, the coating B comprises at least 95 wt.%, and particularly preferably at least 99 wt.%, of high-refractive-index metal oxide(s).

[0249] The coating B has a thickness of at least 50 nm. Preferably, the thickness of coating B is no more than 400 nm, particularly preferably no more than 300 nm.

[0250] Suitable high-refractive-index metal oxides for coating B are preferably selectively light-absorbing (i.e., colored) metal oxides, such as iron(III) oxide (α- and γ-Fe₂O₃, red), cobalt(II) oxide (blue), chromium(III) oxide (green), titanium(III) oxide (blue, usually found mixed with titanium oxynitrides and titanium nitrides), and vanadium(V) oxide (orange), as well as mixtures thereof. Colorless high-refractive-index oxides such as titanium dioxide and / or zirconium oxide are also suitable.

[0251] Coating B can contain a selectively absorbing dye, preferably 0.001 to 5 wt.%, particularly preferably 0.01 to 1 wt.%, in each case based on the total amount of coating B. Suitable dyes are organic and inorganic dyes that can be stably incorporated into a metal oxide coating.

[0252] The coating A preferably comprises at least one low-refractive-index metal oxide and / or metal oxide hydrate. Preferably, coating A comprises at least 95 wt.%, more preferably at least 99 wt.%, low-refractive-index metal oxide (hydrate). Low-refractive-index materials have a refractive index of at most 1.8, preferably at most 1.6.

[0253] Examples of low-refractive-index metal oxides suitable for coating A include silicon dioxide, hydrated silicon dioxide, aluminum oxide, hydrated aluminum oxide, boron oxide, germanium oxide, manganese oxide, magnesium oxide, and mixtures thereof, with silicon dioxide being preferred. The coating A preferably has a thickness of 1 to 100 nm, more preferably 5 to 50 nm, and particularly preferably 5 to 20 nm.

[0254] Preferably, the distance between the surface of the substrate platelets and the inner surface of coating B is at most 100 nm, particularly preferably at most 50 nm, and most preferably at most 20 nm. By ensuring that the thickness of coating A, and thus the distance between the surface of the substrate platelets and coating B, is within the range specified above, it can be ensured that the pigments exhibit high opacity.

[0255] If the pigment based on a lamellar substrate platelet has only one layer A, it is preferred that the pigment has a lamellar substrate platelet made of aluminum and layer A made of silicon dioxide. If the pigment based on a lamellar substrate platelet has a layer A and a layer B, it is preferred that the pigment has a lamellar substrate platelet made of aluminum, layer A made of silicon dioxide, and layer B made of iron oxide.

[0256] According to a preferred embodiment, the pigments have a further coating C of a metal oxide (hydrate) that differs from the underlying coating B. Suitable metal oxides are, for example, silicon dioxide, silicon dioxide 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.

[0257] The coating C preferably has a thickness of 10 to 500 nm, particularly preferably 50 to 300 nm. By providing the coating C, for example based on TiO₂, improved interference can be achieved while maintaining high opacity.

[0258] Layers A and C serve primarily as corrosion protection as well as for chemical and physical stabilization. Layers A and C preferably contain silicon dioxide or aluminum oxide, which are applied using the sol-gel process. This process comprises dispersing the uncoated lamellar substrate plates or the lamellar substrate plates already coated with layer A and / or layer B in a solution of a metal alkoxide such as tetraethyl orthosilicate or aluminum triisopropanolate (usually in a solution of organic solvent or a mixture of organic solvent and water with at least 50 wt% organic solvent such as a C1 to C4 alcohol), and adding a weak base or acid to hydrolyze the metal alkoxide, thereby forming a film of the metal oxide on the surface of the (coated) substrate plates.

[0259] Layer B can be produced, for example, by hydrolytic decomposition of one or more organic metal compounds and / or by precipitation of one or more dissolved metal salts, as well as a possible subsequent treatment (for example, converting a formed hydroxide-containing layer into the oxide layer by annealing).

[0260] Although each of the coatings A, B and / or C may be composed of a mixture of two or more metal oxides (hydrates), each of the coatings is preferably composed of one metal oxide (hydrate).

[0261] The pigments based on coated lamellar or lenticular substrate platelets, or the pigments based on coated VMP substrate platelets, preferably have a thickness of 70 to 500 nm, particularly preferably 100 to 400 nm, and especially preferably 150 to 320 nm, for example 180 to 290 nm. Due to the small thickness of the substrate platelets, the pigment exhibits particularly high opacity. The small thickness of the coated substrate platelets is achieved in particular by keeping the thickness of the uncoated substrate platelets small, but also by minimizing the thickness of coatings A and, if present, C. The thickness of coating B determines the color appearance of the pigment.

[0262] The adhesion and abrasion resistance of pigments based on coated substrate platelets in keratinous material can be significantly increased by modifying the outermost layer—layer A, B, or C, depending on the structure—with organic compounds such as silanes, phosphate esters, titanates, borates, or carboxylic acids. These organic compounds are bound to the surface of the outermost layer A, B, or C, which preferably contains metal oxides. The outermost layer is the layer furthest from the lamellar substrate platelet. The organic compounds are preferably functional silane compounds capable of binding to the metal oxide-containing layer A, B, or C. These can be either monofunctional or bifunctional compounds.Beispiele für bifunktionelle organische Verbindungen sind Methacryloxypropenyltrimethoxysilan, 3-Methacryloxypropyltrimethoxysilan, 3- Acryloxypropyltrimethoxysilan, 2-Acryloxyethyltrimethoxysilan, 3-Methacryloxy- propyltriethoxysilan, 3-Acryloxypropyltrimethoxysilan, 2-Methacryloxyethyl- triethoxysilan, 2-Acryloxyethyltriethoxysilan, 3-Methacryloxypropyltris(methox-yethoxy)silan, 3-Methacryloxypropyltris(butoxyethoxy)silan, 3-Methacryloxy-propyltris(propoxy)silan, 3-Methacryloxypropyltris(butoxy)silan, 3-Acryloxy-propyltris(methoxyethoxy)silan, 3-Acryloxypropyltris(butoxyethoxy)silan, 3-Acryl-oxypropyltris(butoxy)silan, Vinyltrimethoxysilan, Vinyltriethoxysilan, Vinylethyl- dichlorsilan, Vinylmethyldiacetoxysilan, Vinylmethyldichlorsilan, Vinylmethyldiethoxysilan, Vinyltriacetoxysilan, Vinyltrichlorsilan, Phenylvinyldiethoxysilan, oder Phenylallyldichlorsilan.Furthermore, modification with a monofunctional silane, in particular an alkylsilane or arylsilane, is possible. This silane has only one functional group, which can covalently bond to the surface of the pigment based on coated lamellar substrate platelets (i.e., to the outermost metal oxide-containing layer) or, in the case of incomplete coverage, to the metal surface. The hydrocarbon residue of the silane points away from the pigment. Depending on the type and properties of the hydrocarbon residue of the silane, a different degree of hydrophobization of the pigment is achieved. Examples of such silanes are hexadecyltrimethoxysilane, propyltrimethoxysilane, etc. Pigments based on silicon dioxide-coated aluminum substrate platelets surface-modified with a monofunctional silane are particularly preferred. Octyltrimethoxysilane, octyltriethoxysilane, hecadecyltrimethoxysilane, and hecadecyltriethoxysilane are especially preferred.The altered surface properties / hydrophobization can lead to improvements in adhesion, abrasion resistance and alignment during application.

[0263] Suitable pigments based on a lamellar substrate platelet include, for example, the VISIONAIRE series pigments from Eckart.

[0264] Pigments based on a lenticular substrate platelet are available, for example, under the name Alegrace ®< Gorgeous from the company Schlenk Metallic Pigments GmbH.

[0265] Pigments based on a substrate platelet comprising a vacuum metallized pigment are available, for example, under the name Alegrace ®< Marvelous or Alegrace ®< Aurous from Schlenk Metallic Pigments GmbH.

[0266] The pigment(s) can be used in an amount of 0.001 to 20 wt.%, in particular 0.05 to 5 wt.%, in each case based on the total weight of the agent or preparation according to the invention.

[0267] The compositions according to the invention can also contain one or more direct dyes as coloring compounds. Direct dyes are dyes that adhere directly to the hair and do not require an oxidative process to develop the color. Typical direct dyes are nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinones, triarylmethane dyes, or indophenols.

[0268] The direct-acting dyes according to the present invention have a solubility in water (760 mmHg) at 25 °C of more than 0.5 g / L and are therefore not to be considered pigments. Preferably, the direct-acting dyes according to the present invention have a solubility in water (760 mmHg) at 25 °C of more than 1.0 g / L. Particularly preferably, the direct-acting dyes according to the present invention have a solubility in water (760 mmHg) at 25 °C of more than 1.5 g / L.

[0269] Direct-drawing dyes can be divided into anionic, cationic, and nonionic direct-drawing dyes.

[0270] In a further preferred embodiment, a means according to the invention is characterized in that it contains at least one anionic, cationic and / or non-ionic direct dye as a coloring compound.

[0271] In a further preferred embodiment, a method according to the invention is characterized in that the composition (C) contains at least one coloring compound from the group of anionic, nonionic, and / or cationic direct dyes.

[0272] Suitable cationic direct dyes are, for example, 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 No. 16, Basic Blue 99, Basic Brown 16, Basic Brown 17, Basic Yellow 57, Basic Yellow 87, Basic Orange 31, Basic Red 51 Basic Red 76

[0273] Examples of nonionic direct-drawing dyes include nonionic nitro and quinone dyes and neutral azo dyes. Suitable nonionic direct-drawing dyes are those known by their international names.Handelsnamen HC Yellow 2, HC Yellow 4, HC Yellow 5, HC Yellow 6, HC Yellow 12, HC Orange 1, Disperse Orange 3, HC Red 1, HC Red 3, HC Red 10, HC Red 11, HC Red 13, HC Red BN, HC Blue 2, HC Blue 11, HC Blue 12, Disperse Blue 3, HC Violet 1, Disperse Violet 1, Disperse Violet 4, Disperse Black 9 bekannten Verbindungen, sowie 1,4-Diamino-2-nitrobenzol, 2-Amino-4-nitrophenol, 1,4-Bis-(2-hydroxyethyl)-amino-2-nitrobenzol, 3-Nitro-4-(2-hydroxyethyl)-aminophenol, 2-(2-Hydroxyethyl)amino-4,6-dinitrophenol, 4-[(2-Hydroxyethyl)amino]-3-nitro-1-methylbenzol, 1-Amino-4-(2-hydroxyethyl)-amino-5-chlor-2-nitrobenzol, 4-Amino-3-nitrophenol, 1-(2'-Ureidoethyl)amino-4-nitrobenzol, 2-[(4-Amino-2-nitrophenyl)amino]-benzoesäure, 6-Nitro-1,2,3,4-tetrahydrochinoxalin, 2-Hydroxy-1,4-naphthochinon, Pikraminsäure und deren Salze, 2-Amino-6-chloro-4-nitrophenol, 4-Ethylamino-3-nitrobenzoesäure und 2-Chlor-6-ethylamino-4-nitrophenol.

[0274] Anionic direct-drawing dyes are also known as acid dyes. Acid dyes are defined as direct-drawing dyes that possess 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 or sulfonic acid groups exist in equilibrium with their deprotonated forms (-COO⁻, -SO₃⁻). The proportion of protonated forms increases with decreasing pH. When direct-drawing dyes are used in the form of their salts, the carboxylic acid or sulfonic acid groups are present in deprotonated form and are neutralized with corresponding stoichiometric equivalents of cations to maintain electroneutrality. Acid dyes according to the invention can also be used in the form of their sodium salts and / or potassium salts.

[0275] The acid dyes according to the present invention have a solubility in water (760 mmHg) at 25 °C of more than 0.5 g / L and are therefore not to be considered pigments. Preferably, the acid dyes according to the present invention have a solubility in water (760 mmHg) at 25 °C of more than 1.0 g / L.

[0276] Alkaline earth salts (such as calcium and magnesium salts) and aluminum salts of acid dyes often have lower solubility than the corresponding alkali salts. If the solubility of these salts is below 0.5 g / L (25 °C, 760 mmHg), they do not fall under the definition of a direct-drawing dye.

[0277] A key characteristic of acid dyes is their ability to form anionic charges, with the carboxylic acid or sulfonic acid groups responsible for this typically being linked to various chromophoric systems. Suitable chromophoric systems can be found, for example, in the structures of nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinone dyes, triarylmethane dyes, xanthene dyes, rhodamine dyes, oxazine dyes, and / or indophenol dyes.

[0280] The water solubility of anionic direct-acting dyes can be determined, for example, using the following method. Place 0.1 g of the anionic direct-acting dye into a beaker. Add a magnetic stir bar. Then add 100 ml of water. Heat this mixture to 25 °C on a magnetic stirrer while stirring. Stir for 60 minutes. Afterward, visually inspect the aqueous mixture. If undissolved dye remains, increase the amount of water—for example, in 10 ml increments. Continue adding water until the dye is completely dissolved. If the dye-water mixture cannot be visually inspected due to the high intensity of the dye, filter the mixture. If some undissolved dye remains on the filter paper, repeat the solubility test with a larger amount of water.If 0.1 g of the anionic direct-drawing dye dissolves in 100 ml of water at 25 °C, the solubility of the dye is 1.0 g / L.

[0281] Acid Yellow 1 is called 8-Hydroxy-5,7-dinitro-2-naphthalenesulfonic acid disodium salt and has a solubility in water of at least 40 g / L (25°C).

[0282] Acid Yellow 3 is a mixture of the sodium salts of mono- and sisulfonic acids of 2-(2-quinolyl)-1H-indene-1,3(2H)-dione and has a water solubility of 20 g / L (25 °C).

[0283] Acid Yellow 9 is the disodium salt of 8-hydroxy-5,7-dinitro-2-naphthalenesulfonic acid; its water solubility is above 40 g / L (25 °C).

[0290] Thermochromic dyes can also be used. Thermochromism describes the property of a material to change its color, reversibly or irreversibly, depending on the temperature. This can occur through changes in intensity and / or wavelength maximum.

[0291] Finally, it is also possible to use photochromic dyes. Photochromism describes the property of a material to change its color, reversibly or irreversibly, depending on irradiation with light, especially UV light. This can occur through changes in intensity and / or wavelength maximum. Film-forming polymers

[0292] The preparations described above, in particular preparations (B), (C) and (D), and most preferably preparation (D), may contain at least one film-forming polymer.

[0293] Polymers are defined as macromolecules with a molecular weight of at least 1000 g / mol, preferably at least 2500 g / mol, and particularly preferably at least 5000 g / mol, which consist of identical, repeating organic units. The polymers of the present invention can be synthetically produced polymers obtained by polymerization of one type of monomer or by polymerization of different, structurally distinct types of monomers. If the polymer is produced by polymerization of one type of monomer, it is called a homopolymer. If structurally distinct types of monomers are used in the polymerization, the resulting polymer is called a copolymer.

[0294] The maximum molecular weight of the polymer depends on the degree of polymerization (number of polymerized monomers) and the batch size and is also determined by the polymerization method. For the purposes of the present invention, it is preferred that the maximum molecular weight of the film-forming, hydrophobic polymer is no more than 10⁷ g / mol, preferably no more than 10⁶ g / mol, and particularly preferably no more than 10⁵ g / mol.

[0295] For the purposes of the invention, a film-forming polymer is understood to be a polymer capable of forming a film on a substrate, for example, on a keratinous material or a keratinous fiber. The formation of a film can be demonstrated, for example, by examining the keratin material treated with the polymer under a microscope.

[0296] The film-forming polymers can be hydrophilic or hydrophobic.

[0297] In a first embodiment, it may be preferred to use at least one hydrophobic, film-forming polymer in preparation (B), (C) and / or (D), particularly in preparation (D).

[0298] A hydrophobic polymer is defined as a polymer that has a solubility in water at 25 °C (760 mmHg) of less than 1 wt.%.

[0299] The water solubility of the film-forming, hydrophobic polymer can be determined, for example, as follows: 1.0 g of the polymer is placed in a beaker. The volume is then increased to 100 g with water. A magnetic stir bar is added, and the mixture is heated to 25 °C on a magnetic stirrer while stirring. Stirring continues for 60 minutes. The aqueous mixture is then visually inspected. If the polymer-water mixture cannot be visually inspected due to high turbidity, the mixture is filtered. If a proportion of undissolved polymer remains on the filter paper, then the polymer's solubility is less than 1 wt%.

[0300] Examples include acrylic acid-type polymers, polyurethanes, polyesters, polyamides, polyureas, cellulose polymers, nitrocellulose polymers, silicone polymers, acrylamide-type polymers, and polyisoprenes.

[0312] In another embodiment, block copolymers comprising at least one block of styrene or styrene derivatives can be used as film-forming hydrophobic polymers. These block copolymers can be copolymers containing one or more additional blocks besides a styrene block, such as styrene / ethylene, styrene / ethylene / butylene, styrene / butylene, styrene / isoprene, or styrene / butadiene. BASF markets such polymers commercially under the trade name "Luvitol HSB".

[0315] In a first embodiment, it may be preferred to use at least one hydrophilic, film-forming polymer in preparation (B), (C) and / or (D), particularly in preparation (D).

[0316] A hydrophilic polymer is understood to be a polymer that has a solubility in water at 25 °C (760 mmHg) of more than 1 wt.%, preferably of more than 2 wt.%.

[0317] The water solubility of the film-forming, hydrophilic polymer can be determined, for example, by the following method. 1.0 g of the polymer is placed in a beaker. The volume is increased to 100 g with water. A magnetic stir bar is added, and the mixture is heated to 25 °C on a magnetic stirrer while stirring. Stirring continues for 60 minutes. The aqueous mixture is then visually inspected. A completely dissolved polymer appears macroscopically homogeneous. If the polymer-water mixture cannot be visually inspected due to high turbidity, the mixture is filtered. If no undissolved polymer remains on the filter paper, then the polymer's solubility is greater than 1 wt%.

[0318] Nonionic, anionic and cationic polymers can be used as film-forming, hydrophilic polymers.

[0319] Suitable film-forming, hydrophilic polymers can be selected, for example, from the group of polyvinylpyrrolidone (co)polymers, polyvinyl alcohol (co)polymers, vinyl acetate (co)polymers, carboxyvinyl (co)polymers, acrylic acid (co)polymers, methacrylic acid (co)polymers, natural gums, polysaccharides and / or acrylamide (co)polymers.

[0320] Furthermore, it is particularly preferred to use polyvinylpyrrolidone (PVP) and / or a vinylpyrrolidone-containing copolymer as the film-forming hydrophilic polymer.

[0321] In a further particularly preferred embodiment, a means 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 the copolymers of polyvinylpyrrolidone.

[0322] It is further preferred if the agent according to the invention contains polyvinylpyrrolidone (PVP) as a film-forming, hydrophilic polymer. Surprisingly, the wash fastness of the dyes obtained with PVP-containing agents (b9) was also very good.
