Description

Bis (triethoxysilylpropyl) amine in combination with a thickener

The present invention relates to cosmetic compositions for treating a keratinous material, the composition comprising an organic silicon compound and at least one thickener, and to 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.

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.

The object on which the present invention is based is to provide a cosmetic product which enables the hair to have a good care effect, improves the structural protection against chemical stress and at the same time its physical properties

Texture represents a manageable product. This object is achieved by a cosmetic agent for treating a keratinous material, comprising a) at least one organic silicon compound and

b) at least one thickener.

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.

The cosmetic agent for treating a keratinous material contains at least one organic silicon compound as the first constituent essential to the invention. 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 group 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.
