Description

Bis (triethoxysilylpropyl) amine in combination with an alkane

The present invention relates to cosmetic compositions for treating a keratinous material, the composition comprising an organic silicon compound and a branched or linear C8-C30 alkane, and the use of the cosmetic composition.

The external exposure of the hair to chemicals from a variety of different sources poses challenges to the development of cosmetic care products. Air and

Water contamination has a detrimental effect on the skin and hair. The most important

Air pollutants include polycyclic aromatic hydrocarbons, volatile organic ones

Compounds, nitrogen oxides (NOx), particles and cigarette smoke. The effect of different

Luftsch ad substances can be intensified in the presence of other air pollutants and under the influence of UV radiation.

It is known that the toxicity of gaseous air pollutants, such as sulfur dioxide, ozone and nitrogen oxides, is particularly related to their free radical initiator activity, which contributes to

Creatures cause damage. Free radicals are metabolic products that also occur naturally in the body. In large quantities, free radicals can promote irritation and inflammation and accelerate the aging process. In this case one speaks of "oxidative damage". Free radicals can also cause hair damage, for example as

Reduction of the shine as well as the feel and / or fading of the hair color becomes visible.

Particles are a complex mixture that contain metals, minerals, organic toxins and / or biological materials. They too can promote the formation of free radicals.

Furthermore, changing consumer wishes with regard to a certain condition of the hair are often associated with a recurring chemical stress on the hair. For example, hair coloring stresses the hair, which may require special, intensive care.

The prior art describes organosilicon compounds from the group of the silanes which comprise at least one hydroxyl group and / or hydrolyzable group. Due to the

In the presence of the hydroxyl groups and / or hydrolyzable groups, the silanes are reactive substances which hydrolyze or oligomerize or polymerize in the presence of water. The oligomerization or polymerization of the silanes initiated by the presence of the water ultimately leads to the formation of a film when used on a keratinic material, which film can develop a protective effect.

There is a need for a product that has the adverse effects of chemical

Hair treatments can heal. In particular, there is a need for a post-treatment product that is capable of curing the damage to the hair surface. The object underlying the present invention is to provide a product with an improved care and / or protective effect. In particular, the object of the present invention was to provide a cosmetic agent which, as an aftertreatment product, heals damage to the hair surface.

This object is achieved by a cosmetic agent for the treatment of a keratinous material, comprising

a) at least one organic silicon compound containing one to three silicon atoms, and b) at least one branched or linear alkane, the alkane being a C8-C30 alkane, preferably a C10-C24 alkane, more preferably a C12-C18 alkane and even more preferably one C14-C16 is alkane.

A keratinous material means hair, skin, nails (such as fingernails and / or toenails). Wool, furs and feathers also fall under the definition of keratinous material.

A keratin material is preferably understood to mean human hair, human skin and human nails, in particular fingernails and toenails. Keratinous material is very particularly preferably understood to mean human hair, in particular scalp and / or whiskers.

As the first constituent essential to the invention, the cosmetic agent for treating a keratinous material contains at least one organic silicon compound which contains one to three silicon atoms. Preferred organic silicon compounds are selected from silanes with one, two or three silicon atoms, the organic silicon compound comprising one or more hydroxyl groups and / or hydrolyzable groups per molecule.

Organic silicon compounds, which are also referred to alternatively as organosilicon compounds, are compounds which either have a direct silicon-carbon bond (Si-C) or in which the carbon is attached to the silicon via an oxygen, nitrogen or sulfur atom. Atom is attached. The organic silicon compounds are compounds that contain one to three silicon atoms. The organic silicon compounds particularly preferably contain one or two

Silicon atoms.

According to the lUPAC rules, the term silane stands for a group of substances that are based on a silicon framework and hydrogen. In the case of organic silanes, the hydrogen atoms are completely or partially replaced by organic groups such as (substituted) alkyl groups and / or alkoxy groups. Some of the hydrogen atoms in the organic silanes can also be replaced by hydroxyl groups.

The agent for treating a keratinous material contains at least one organic

Silicon compound, which is preferably selected from silanes with one, two or three silicon atoms, wherein the organic silicon compound comprises one or more hydroxyl groups or hydrolyzable groups per molecule.

In a very particularly preferred embodiment, the agent for treating a keratinous material has at least one organic silicon compound selected from silanes with one, two or three silicon atoms, the organic silicon compound also having one or more basic groups and one or more hydroxyl groups or hydrolyzable groups per molecule.

The hydrolyzable group or groups is preferably a C 1 -C 6 -alkoxy group, in particular an ethoxy group or a methoxy group. It is preferred if the hydrolyzable group is attached directly to the silicon atom. If, for example, the hydrolyzable group is an ethoxy group, the organic silicon compound preferably contains a structural unit R'R "R"'Si-0-CH ₂ -CH3. The radicals R ', R "and R"' represent the three remaining free valences of the silicon atom.

Very particularly good results have been obtained if the agent for treating a keratinous material contains at least one organic silicon compound of the formula (I) and / or (II).

The compounds of formulas (I) and (II) are organic silicon compounds selected from silanes with one, two or three silicon atoms, the organic silicon compound comprising one or more hydroxyl groups and / or hydrolyzable groups per molecule.

The organosilicon compounds of the formula (II) have the silicon-containing groups (RsO) c (R6) dSi- and -Si (R6 ’) d '(OR5’) c \ at their two ends.

In the middle part of the molecule of the formula (II) are the groupings - (A) _e - and - [NR7- (A ')] _f - and - [0- (A ”)] _g - and - [NR8- (A '”)] _H - Each of the residues e, f, g and h can independently of one another stand for the number 0 or 1, with the proviso that at least one of the residues e, f, g and h is different from 0.

0.5 to 5% by weight of at least one first organic silicon compound which is selected from the group consisting of (3-aminopropyl) trimethoxysilane, (3-aminopropyl) triethoxysilane, (2-aminoethyl) trimethoxysilane, (2-aminoethyl) triethoxysilane , (3-Dimethylaminopropyl) trimethoxysilane, (3-Dimethylaminopropyl) triethoxysilane (2-Dimethylaminoethyl) trimethoxysilane and (2-Dimethylaminoethyl) triethoxysilane, and

Even the addition of small amounts of water leads to hydrolysis in organic silicon compounds with at least one hydrolyzable group. The hydrolysis products and / or organic

Silicon compounds with at least one hydroxyl group can react with one another in a condensation reaction. For this reason, both the organosilicon compounds with at least one hydrolyzable group and their hydrolysis and / or condensation products can be present in the agent. When using organosilicon compounds with at least one hydroxyl group, both the organic silicon compounds with at least one hydroxyl group and their condensation products may be present in the agent.

A condensation product is understood to mean a product that by reaction of at least two organic silicon compounds, each with at least one hydroxyl group or

hydrolyzable groups per molecule with elimination of water and / or with elimination of an alkanol. The condensation products can be, for example, dimers, but also trimers or oligomers, the condensation products being in equilibrium with the monomers. Depending on the amount of water used or consumed in the hydrolysis, the balance shifts from monomeric organic silicon compounds to the condensation product.

In the context of the present invention, data in% by weight - unless stated otherwise - are always based on the total weight of the cosmetic product.

As a second constituent essential to the invention, the cosmetic agent for treating a keratinous material contains a branched or linear alkane.

It has surprisingly been found that the combination of (3-aminopropyl) triethoxysilane with C8-C30 alkanes increases the cosmetic acceptance.
