Bis(triethoxysilylpropyl)amine in combination with lanthanum chloride

Description

[0001] The present invention relates to a cosmetic agent for treating a keratinous material, wherein the cosmetic agent is a fluid and comprises at least one organic silicon compound, in particular bis(triethoxysilylpropyl)amine, and at least one polyvalent metal cation, and the use of the cosmetic agent.

[0002] The cosmetic treatment of skin and hair is an important part of personal hygiene. Today, human hair is treated in a variety of ways with hair cosmetic preparations. These include cleansing with shampoos, conditioning and regenerating with conditioners and treatments, as well as bleaching, coloring, and styling with dyes, tints, perming solutions, and other styling products. Products for changing or toning the color of the hair play a particularly important role. Apart from bleaching agents, which lighten hair oxidatively by breaking down the natural hair pigments, three main types of hair dyes are important in the field of hair coloring: For permanent, intense colorations with corresponding colorfastness properties, so-called oxidative dyes are used.Such dyes typically contain oxidation dye precursors, so-called developer components and coupler components.

[0003] If the dyes produced during the coloring process or applied directly to the hair have significantly different fastness properties (e.g., UV stability, perspiration fastness, wash fastness, etc.), a noticeable and therefore undesirable color shift can occur over time. Frequent washing or other hair care treatments can also cause color shifts. This phenomenon is more pronounced when the hairstyle includes hair or hair sections with varying degrees of damage. Long hair is a good example, where the ends, which have been exposed to all sorts of environmental influences for a long time, are usually much more damaged than the relatively new, regrown sections.

[0004] For temporary coloring, dyes or tints containing so-called direct dyes as the coloring component are typically used. These are dye molecules that adhere directly to the hair and do not require an oxidative process to develop the color. These dyes are generally much more sensitive to shampooing than oxidative dyes, so that an often undesirable shift in shade or even visible "fading" occurs much more quickly.

[0005] In another common hair coloring method, precursors of the natural hair pigment melanin are applied to the hair; these then form naturally occurring pigments through oxidative processes within the hair. For example, 5,6-dihydroxyindoline is used as a dye precursor in such processes. With repeated applications of products containing 5,6-dihydroxyindoline, it is possible to restore the natural hair color of people with gray hair. The coloring process can be carried out using atmospheric oxygen as the sole oxidizing agent, eliminating the need for any other oxidizing agents.

[0006] Several problems arise with all hair coloring. Firstly, unwanted staining of the skin can occur when rinsing out the hair dye. This effect can also lead to lighter strands being recolored by the dye during rinsing, or the dye from darker strands staining the lighter base hair. Generally, the rinsing of dyes has the disadvantage of altering the originally desired color. Hair dyes with red or blue tones, in particular, have a shorter retention time in the hair, so their rinsing can lead to undesirable colors. Color-protecting products are used to counteract this problem.

[0007] On the other hand, all chemical stresses complicate coloring processes. The external stress on hair from chemicals of numerous different sources poses challenges for the development of cosmetic coloring products. Air and water pollution have a detrimental effect on skin and hair. The most important air pollutants include polycyclic aromatic hydrocarbons, volatile organic compounds, nitrogen oxides (NOx), particulate matter, and cigarette smoke. The effects of various air pollutants can be intensified in the presence of other air pollutants and under the influence of UV radiation.

[0008] Cosmetic products are known in the prior art that comprise a silane compound in combination with various polyvalent metal cations such as Mg, Zn, Al, Bi, Si, Ti, Fe, Ca, etc.

[0009] US patent 2010 / 083446 A1 discloses a hair treatment product containing a silane, a hydrophobic film-forming polymer, pigments, and a volatile solvent. German patent DE 10 2004 013795 A1 describes products containing substituted aminopolyorganosiloxanes.

[0010] Therefore, there is a need for products that provide a special conditioning effect for hair to enable optimal coloring processes and ensure that the hair retains a long-lasting, desired color.

[0011] The objective of the present invention is to provide a product with improved care and / or protection. In particular, the objective of the present invention was to provide a cosmetic product that provides special care for stressed hair and reduces the effects of fading or color change.

[0012] This problem is solved by a cosmetic agent for treating a keratinous material, wherein the cosmetic agent is a fluid and a) at least one organic silicon compound, wherein the at least one organic silicon compound comprises a compound of formula (I) and at least one organic silicon compound of formula (IV), wherein in the organic silicon compound of formula (I) R1 R2 NL-Si(OR3) a (R4) b (I), R1, R2 both represent a hydrogen atom, L represents a linear, divalent C1-C6 alkylene group, preferably a propylene group (-CH2-CH2-CH2-) or an ethylene group (-CH2-CH2-), R3, R4 independently represent a methyl group or an ethyl group, a represents the number 3 and b represents the number 0, and wherein in the organic silicon compound of formula (IV) R9 Si(OR10) k (R11) m (IV), R9 represents a C1-C 12 -alkyl group, R 10 stands for a hydrogen atom or a C 1 -C 6 -alkyl group, R 11 stands for a C 1 -C 6 -alkyl group, k stands for an integer from 1 to 3,and m represents the integer 3 - k, and b) comprises at least one polyvalent metal cation, comprising lanthanum in the form of lanthanum chloride, in a molar concentration of 0.001 mol / L to 2 mol / L, preferably 0.005 mol / L to 1.5 mol / L, more preferably 0.01 to 1 mol / L, most preferably 0.02 to 0.5 mol / L.

[0013] Keratinous materials include hair, skin, and nails (such as fingernails and / or toenails). Wool, fur, and feathers also fall under the definition of keratinous materials.

[0014] The term "keratinous material" preferably refers to human hair, human skin, and human nails, especially fingernails and toenails. Most preferably, the term "keratinous material" refers to human hair, especially head and / or beard hair.

[0015] As the first essential component of the invention, the cosmetic agent for treating a keratinous material contains at least one organic silicon compound selected from silanes having one, two or three silicon atoms, wherein the organic silicon compound comprises one or more hydroxyl groups and / or hydrolyzable groups per molecule.

[0016] Organic silicon compounds, also known 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. These organic silicon compounds contain one to three silicon atoms. Particularly preferably, the organic silicon compounds contain one or two silicon atoms.

[0017] According to IUPAC rules, the term silane refers to a group of chemical compounds based on a silicon skeleton 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. In organic silanes, some of the hydrogen atoms may also be replaced by hydroxyl groups.

[0018] The agent for treating a keratinous material contains at least one organic silicon compound selected from silanes having one, two or three silicon atoms, wherein the organic silicon compound comprises one or more hydroxyl groups or hydrolyzable groups per molecule.

[0019] The agent for treating a keratinous material comprises at least one organic silicon compound selected from silanes having one, two or three silicon atoms, wherein the organic silicon compound also includes one or more basic groups and one or more hydroxyl groups or hydrolyzable groups per molecule.

[0020] This basic group is an amino group that is linked to a silicon atom via a linker.

[0023] In the organic silicon compounds of formula (I) R 1 R 2 NL-Si(OR 3 ) a (R 4 ) b (I ), the substituents R 1 and R 2 both represent a hydrogen atom.

[0024] In the middle part of the organic silicon compound is the structural unit or linker -L- which stands for a linear or branched, divalent C 1 -C 20 -alkylene group.

[0025] -L- represents a linear divalent C1-C6 alkylene group.

Most preferably, L represents a propylene group (-CH2-CH2-CH2-).

[0026] The organic silicon compounds of formula (I) R 1 R 2 NL-Si(OR 3 ) a (R 4 ) b (I) each have at one end the silicon-containing group -Si(OR 3 ) a (R 4 ) b .

[0027] In the terminal structural unit -Si(OR 3 ) a (R 4 ) b, R 3 and R 4 independently represent a methyl group or an ethyl group.

[0028] Here, a represents an integer of 3 and b equals 0.

[0029] The best protection against the negative effects of water and / or air pollution (“anti-pollution” effect) and the best care of stressed hair could be obtained when the agent for treating a keratinous material contains at least one organic silicon compound of formula (I) in which the residues R 3 , R 4 independently stand for a methyl group or for an ethyl group.

[0030] Particularly suitable organic silicon compounds of formula (I) are (3-Aminopropyl)triethoxysilane (3-Aminopropyl)trimethoxysilane (2-Aminoethyl)triethoxysilane (2-Aminoethyl)trimethoxysilane (3-Dimethylaminopropyl)triethoxysilane (3-Dimethylaminopropyl)trimethoxysilane (2-Dimethylaminoethyl)triethoxysilane and / or (2-Dimethylaminoethyl)trimethoxysilane.

[0032] (3-Aminopropyl)trimethoxysilane can be purchased from Sigma-Aldrich, for example. (3-Aminopropyl)triethoxysilane is also commercially available from Sigma-Aldrich.

[0033] In a further embodiment, the agent for treating a keratinous material can also include at least one organic silicon compound of formula (II) (R 5 O) c (R 6 ) d Si-(A) e -[NR 7 -(A')] f -[O-(A")] g -[NR 8 -(A‴)] h -Si(R 6 ') d' (OR 5 ') c' (II).

[0034] The organosilicon compounds of formula (II) each bear at their two ends the silicon-containing groups (R 5 O) c (R 6 ) d Si- and -Si(R 6 ') d' (OR 5 ') c' .

[0035] The central part of the molecule of formula (II) contains the groups -(A) e - and -[NR 7 -(A')] f - and -[O-(A")] g - and -[NR 8 -(A‴)] h -. Each of the substituents e, f, g, and h can independently represent the number 0 or 1, provided that at least one of the substituents e, f, g, and h is non-0. In other words, an organic silicon compound of formula (II) contains at least one substituent from the group consisting of -(A)- and -[NR 7 -(A')]- and -[O-(A")]- and -[NR 8 -(A‴)]-

[0036] In the two terminal structural units (R 5 O) c (R 6 ) d Si- and -Si(R 6 ') d' (OR 5 ') c', the residues R5, R5', R5" independently represent either a hydrogen atom or a C 1 -C 6 alkyl group. The residues R6, R6' and R6" independently represent a C 1 -C 6 alkyl group.

[0037] Here, c represents an integer from 1 to 3, and d represents the integer 3 - c. If c represents the number 3, then d equals 0. If c represents the number 2, then d equals 1. If c represents the number 1, then d equals 2.

[0038] Similarly, c' represents an integer from 1 to 3, and d' represents the integer 3 - c'. If c' represents the number 3, then d' equals 0. If c' represents the number 2, then d' equals 1. If c' represents the number 1, then d' equals 2.

[0039] A very high anti-pollution effect of the agent for treating a keratinous material was obtained when the residues c and c' both represent the number 3. In this case, d and d` both represent the number 0.

[0040] In a further preferred embodiment, the agent for treating a keratinous material further comprises at least one organic silicon compound of formula (II) (R 5 O) c (R 6 ) d Si-(A) e -[NR 7 -(A')] f -[O-(A")] g -[NR 8 -(A‴)] h -Si(R 6 ') d' (OR 5 ,< ) c' (II), wherein R5 and R5' independently represent a methyl group or an ethyl group, c and c' both represent the number 3, and d and d' both represent the number 0.

[0041] If c and c' both represent the number 3 and d and d' both represent the number 0, the organic silicon compounds correspond to the formula (IIa) (R 5 O) 3 Si-(A) e -[NR 7 -(A') f [O-(A")] g -[NR 8 -(A‴)] h -Si(OR 5 ') 3 (IIa).

[0042] The residues e, f, g, and h can independently represent the number 0 or 1, with at least one residue from e, f, g, and h being non-zero. The abbreviations e, f, g, and h thus define which of the groupings -(A) e - and -[NR 7 -(A')] f - and -[O-(A")] g - and -[NR 8 -(A‴)] h - are located in the middle section of the organic silicon compound of formula (II).

[0043] In this context, the presence of certain groupings has proven particularly advantageous with regard to increasing the "anti-pollution" effect. Especially good results were obtained when at least two of the residues e, f, g, and h represent the number 1. It is particularly advantageous when e and f both represent the number 1. Furthermore, it is particularly advantageous when g and h both represent the number 0.

[0044] If e and f both represent the number 1 and g and h both represent the number 0, the organic silicon compounds correspond to the formula (Ilb) (R 5 O) c (R 6 ) d Si-(A)-[NR 7 -(A')]-Si(R 6 ') d' (OR 5 ') c' (IIb).

[0045] The residues A, A', A", A‴, and Aʺʺ independently represent a linear or branched, divalent C1-C20 alkylene group. Preferably, the residues A, A', A", A‴, and Aʺʺ independently represent a linear, divalent C1-C20 alkylene group. More preferably, the residues A, A', A", A‴, and Aʺʺ independently represent a linear, divalent C1-C6 alkylene group. Particularly preferably, the residues A, A', A", A‴, and Aʺʺ independently represent a methylene group (-CH2-), an ethylene group (-CH2-CH2-), a propylene group (-CH2-CH2-CH2-), or a butylene group (-CH2-CH2-CH2-CH2-). The residues A, A', A", A‴ and Aʺʺ are particularly favored to represent a propylene group (-CH 2 -CH 2 -CH 2 -).

[0046] If the remainder f represents the number 1, then the organic silicon compound of formula (II) contains a structural grouping -[NR 7 -(A')]-.

[0047] If the remainder h represents the number 1, then the organic silicon compound of formula (II) contains a structural grouping -[NR 8 -(A‴)]-.

[0048] Here, the residues R 7 and R 8 independently represent a hydrogen atom, a C 1 -C 6 alkyl group, a hydroxy-C 1 -C 6 alkyl group, a C 2 -C 6 alkyl group, an amino-C 1 -C 6 alkyl group or a group of the formula (III) - (Aʺʺ)-Si(R 6 ") d "(OR 5 ") c " (III).

[0049] The residues R 7 and R 8 are particularly preferred, independently of each other, to represent a hydrogen atom, a methyl group, a 2-hydroxyethyl group, a 2-alkenyl group, a 2-aminoethyl group or a grouping of formula (III).

[0050] If the residue f represents the number 1 and the residue h represents the number 0, the organic silicon compound contains the group [NR 7 -(A')], but not the group -[NR 8 -(A‴)]. If the residue R7 now represents a group of formula (III), then the agent for treating a keratinous material contains an organic silicon compound with 3 reactive silane groups.

[0051] In a further preferred embodiment, the agent for treating a keratinous material contains at least one organic silicon compound of formula (II) (R 5 O) c (R 6 ) d Si-(A) e -[NR 7 -(A')] f -[O-(A")] g -[NR 8 -(A‴)] h -Si(R 6 ') d (OR 5 ') c' (II), wherein e and f both represent the number 1, g and h both represent the number 0, A and A` independently represent a linear, divalent C 1 -C 6 alkylene group and R7 represents a hydrogen atom, a methyl group, a 2-hydroxyethyl group, a 2-alkenyl group, a 2-aminoethyl group or a grouping of formula (III).

[0059] The compounds of formula (IV) are organic silicon compounds selected from silanes having one, two or three silicon atoms, wherein the organic silicon compound comprises one or more hydroxyl groups and / or hydrolyzable groups per molecule.

[0060] The organic silicon compounds of formula (IV) can also be referred to as silanes of the type of alkylalkoxysilanes or alkylhydroxysilanes, R 9 Si(OR 10 ) k (R 11 ) m (IV), wherein R 9 represents a C 1 -C 12 alkyl group, R 10 represents a hydrogen atom or a C 1 -C 6 alkyl group, R 11 represents a C 1 -C 6 alkyl group, k represents an integer from 1 to 3, and m represents the integer 3 - k.

[0067] Highly advantageous effects were obtained when the agent for treating a keratinous material contained at least one organic silicon compound of formula (IV), in which the residue k represents the number 3. In this case, the residue m represents the number 0.

[0068] Organic silicon compounds of formula (IV) are particularly suitable for solving the problem.

[0069] The organic silicon compounds described above are reactive compounds.

[0070] In this context, it has proven to be particularly advantageous if the agent contains (3-Aminopropyl)triethoxysilane, i.e., an aminopropyltriethoxysilane (AMEO), as an organic silicon compound.

[0071] According to preferred embodiments of the present invention, the organic silicon compound of formula (I), in particular the (3-aminopropyl)triethoxysilane, is contained in the cosmetic product in an amount of 0.01 to 10 wt.%, preferably 0.02 to 8 wt.%, more preferably 0.05 to 6 wt.%, most preferably 0.1 to 4 wt.%, based on the total weight of the cosmetic product.

[0072] It has been found that particularly stable and uniform films could be obtained on the keratinous material even when the agent contains two structurally different organic silicon compounds, each containing one to three silicon atoms.

[0073] The agent is characterized by containing at least one organic silicon compound of formula (I) and at least one organic silicon compound of formula (IV).

[0074] In a particularly preferred embodiment, a composition is characterized in that it contains at least one organic silicon compound of formula (I) selected from the group consisting of (3-aminopropyl)triethoxysilane and (3-aminopropyl)trimethoxysilane, and additionally contains at least one organic silicon compound of formula (IV) selected from the group consisting of methyltrimethoxysilane, methyltriethoxysilane, ethyltrimethoxysilane, ethyltriethoxysilane, propyltrimethoxysilane, propyltriethoxysilane, hexyltrimethoxysilane and hexyltriethoxysilane.

[0076] Even the addition of small amounts of water leads to the hydrolysis of organosilicon compounds with at least one hydrolyzable group. The hydrolysis products and / or organosilicon compounds with at least one hydroxyl group can react with each other in a condensation reaction. For this reason, both the organosilicon compounds with at least one hydrolyzable group and their hydrolysis and / or condensation products may be present in the product. When using organosilicon compounds with at least one hydroxyl group, both the organosilicon compounds with at least one hydroxyl group and their condensation products may be present in the product.

[0077] A condensation product is defined as a product formed by the reaction of at least two organic silicon compounds, each with at least one hydroxyl group or hydrolyzable group per molecule, with the elimination of water and / or an alkanol. Condensation products can be, for example, dimers, trimers, or oligomers, in equilibrium with the monomers. Depending on the amount of water used or consumed in the hydrolysis, the equilibrium shifts from the monomeric organic silicon compounds to the condensation product.

[0078] Within the scope of the present invention, values ​​given in wt.% - unless otherwise specified - always refer to the total weight of the cosmetic product.

[0079] According to the present invention, the cosmetic agent is a fluid. In this context, a fluid is understood to be a non-gaseous, flowable mass. The fluid contains the multivalent metal cation, in particular a divalent metal cation, in a specific molar concentration.

[0080] As a second essential component of the invention, the cosmetic agent for treating a keratinous material contains a polyvalent metal cation comprising lanthanum in the form of lanthanum chloride. In the course of the work leading to this invention, it has been found that, in order to solve the problem underlying the invention, it is particularly advantageous if the organic silicon compounds, for example 3-(triethoxysilyl)-N-[3-(triethoxysilyl)propyl]-1-propanamine, i.e., a bis(triethoxysilylpropyl)amine, are combined with a divalent metal cation comprising lanthanum in the form of lanthanum chloride.

[0081] It has been found that the combination of bis(triethoxysilylpropyl)amine with a divalent metal cation, comprising lanthanum in the form of lanthanum chloride, protects hair from the fading of artificial hair dyes. Furthermore, particularly in oxidatively damaged hair, the hair surface becomes more hydrophobic, and the denaturation temperature, hair swelling, and tensile-elongation parameters are improved or favorably altered. By improving these parameters, the physical properties of damaged hair are restored to a level comparable to that of undamaged hair, thus indicating that the hair structure has been restabilized.

[0082] According to a preferred embodiment, the pH value of the cosmetic agent is 1 to 9, preferably 1.5 to 8, more preferably 2 to 7, even more preferably 2.5 to 6 and most preferably 3 to 5.

[0120] The combinations in the table above represent active ingredient combinations that are combined in cosmetic products with other components described above.

[0121] The active ingredient combination of the organic silicon compound and the multivalent metal cation can already be contained in the agent for treating keratinous materials. In this embodiment, the agent for treating keratinous materials is sold in a ready-to-use form. To ensure the most stable storage possible, the agent itself is preferably formulated with a low water content or is anhydrous.

[0122] Alternatively, the at least one organic silicon compound is added to a base comprising all ingredients of the agent for treating a keratinous material, with the exception of the at least one organic silicon compound, a maximum of 12 hours, preferably a maximum of 6 hours, more preferably a maximum of 3 hours, and even more preferably a maximum of 1 hour before application of the agent for treating a keratinous material.

[0123] Alternatively, the organic silicon compound and the further component b) are added to a cosmetic product only shortly before application, i.e. 1 minute to 12 hours, preferably 2 minutes to 6 hours, particularly preferably 1 minute to 3 hours, especially preferably 1 minute to 1 hour.

[0124] In another alternative, the organic silicon compounds are added to an aqueous solution which is applied to the hair, and in the second step an aqueous solution or a cosmetic product containing the further component b) is applied to the hair and the hair is thus treated afterwards.

[0125] For example, the user can first mix or shake an agent (α) containing the organic silicon compound(s) with an agent (β) comprising the remaining ingredients of the agent for treating keratinous materials. This mixture of (α) and (β) can then be applied to the keratinous materials, either directly after preparation or after a short reaction time of 1 to 20 minutes. The agent (β) may contain water, in particular water in an amount > 30% by weight, based on the total weight of the agent for treating keratinous materials.

[0126] Regarding other preferred embodiments of use, what has been said about cosmetic products applies mutatis mutandis.
