ACTIVE INGREDIENT COMPOSITION FOR CHANGING THE SHAPE OF THE HAIR COLLECTIVE

Description

[0001] The disclosure relates to cosmetic agents for the treatment of a keratinous material, wherein the agent comprises an organic silicon compound and at least one copolymer which is composed at least of the monomer units N-tert-octylacrylamide, acrylic acid and tert-butylaminoethyl methacrylate, as well as the use of the cosmetic agent.

[0002] External stress on hair from chemical substances of numerous different sources presents challenges for the development of cosmetic products. Air and water pollution have a detrimental effect on skin and hair. Among the most important air pollutants are 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 or heat.

[0003] It is known that the toxicity of gaseous air pollutants, such as sulfur dioxide, ozone, and nitrogen oxides, is primarily linked to their activity as initiators of free radicals, which cause damage to living organisms. Free radicals are metabolic byproducts that also occur naturally in the body. In large quantities, free radicals can promote irritation and inflammation and accelerate the aging process. This is known as "oxidative damage." Free radicals can also damage hair, which can manifest as a reduction in shine and manageability, and / or fading of hair color. Exposure to heat naturally exacerbates the damage caused by pollutants.

[0004] Customer wishes extend beyond simply the appearance of the hair itself. The requirements for cosmetic hair products are more diverse. Cosmetic products that provide permanent or temporary styling also play a crucial role in the cosmetics industry. These products should enable temporary styling with good hold. Developing cosmetic products that offer both good hold and protection against damage from pollutants presents a significant challenge.

[0005] The prior art describes organosilicon compounds from the silane group, which comprise at least one hydroxyl group and / or a hydrolyzable group. Due to the presence of these hydroxyl and / or hydrolyzable groups, silanes are reactive substances that hydrolyze, oligomerize, or polymerize in the presence of water. When applied to a keratinous material, the oligomerization or polymerization of silanes initiated by the presence of water ultimately leads to the formation of a film that can provide a protective effect.

[0006] The object underlying the present invention is to provide a cosmetic product that enables good shaping of the hair and improves structural protection against heat exposure.

[0007] This problem is solved by a cosmetic agent for treating a keratinous material according to claim 1.

[0008] 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.

[0026] Here, 'a' represents an integer from 1 to 3, and 'b' represents the integer 3 - 'a'. If 'a' represents the number 3, then 'b' equals 0. If 'a' represents the number 2, then 'b' equals 1. If 'a' represents the number 1, then 'b' equals 2.

[0027] 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.

[0028] Organic silicon compounds of formula (I) revealed in detail are (3-Aminopropyl)triethoxysilane (3-Aminopropyl)trimethoxysilane 1-(3-Aminopropyl)silanetriol (2-Aminoethyl)triethoxysilane (2-Aminoethyl)trimethoxysilane 1-(2-Aminoethyl)silanetriol (3-Dimethylaminopropyl)triethoxysilane (3-Dimethylaminopropyl)trimethoxysilane 1-(3-Dimethylaminopropyl)silanetriol (2-Dimethylaminoethyl)triethoxysilane.

[0031] In a further embodiment, the agent for treating a keratinous material may additionally contain an 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).

[0032] 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' .

[0033] 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 a -(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‴)]-.

[0040] 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).

[0041] 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.

[0042] 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.

Particularly preferably, the residues A, A', A", A‴, and A"" 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 A"" are particularly favored to represent a propylene group (-CH 2 -CH 2 -CH 2 -).

[0045] If the remainder f represents the number 1, then the organic silicon compound of formula (II) contains a structural grouping -[NR 7 -(A')]-.

[0046] If the remainder h represents the number 1, then the organic silicon compound of formula (II) contains a structural grouping -[NR 8 -(A‴)]-.

[0047] 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) - (A"")-Si(R 6 ") d "(OR 5 ") c " (III).

[0048] 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).

[0049] If the remainder f represents the number 1 and the remainder h represents the number 0, the organic silicon compound contains the group [NR 7 -(A')], but not the group -[NR 8 -(A‴)]. If the remainder 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.

[0050] In a further disclosure, 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).

[0072] The organic silicon compounds described above are reactive compounds.

[0073] 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.

[0074] In a preferred embodiment, a composition is characterized in that it contains at least one organic silicon compound of formula (I) and at least one organic silicon compound of formula (IV).

[0077] 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.

[0078] 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.

[0079] Within the scope of the present invention, values ​​given in wt.% - unless otherwise specified - always refer to the total weight of the cosmetic product.

[0080] As a second essential component of the invention, the cosmetic agent for treating a keratinous material contains a firming copolymer derived from the monomer units N-tert-octylacrylamide, acrylic acid, and tert-butylaminoethyl methacrylate. During the work leading to this invention, it was found that, to achieve a particularly good conditioning effect, it is especially advantageous to combine the organic silicon compounds, in particular (3-aminopropyl)triethoxysilane, with the firming copolymer derived from the monomer units N-tert-octylacrylamide, acrylic acid, and tert-butylaminoethyl methacrylate.

[0081] The combination of the organic silicon compound, in particular (3-aminopropyl)triethoxysilane, with the strengthening copolymer derived from the monomer units N-tert-octylacrylamide, acrylic acid, and tert-butylaminoethyl methacrylate forms a layer on the hair. These strengthening copolymers are also called film-forming copolymers or film formers. This ensures that oxidative hair dyes are significantly protected from washing out. Furthermore, the hair surface of oxidatively damaged hair is made hydrophobic again, which reduces frizz. In addition, the hair's combability is improved.

[0082] Firming copolymers, which according to the present invention are to be included in the cosmetic product, are commercially available.
