Description

[0001] Surfactant-containing cosmetic product in combination with bis(triethoxysilylpropyl)amine for

[0002] Cleaning and care of human hair

[0003] The present invention relates to cosmetic agents for the treatment of a keratinous material, wherein the agent comprises an organic silicon compound and an anionic, nonionic or amphoteric surfactant, and the use of the cosmetic agent.

[0004] The external stress on hair caused by chemical substances from a variety of different sources presents challenges for the development of cosmetic care products. Air and

[0005] Water pollution has a detrimental effect on skin and hair. Among the most important

[0006] Air pollutants include polycyclic aromatic hydrocarbons and volatile organic compounds.

[0007] Compounds, nitrogen oxides (NOx), particles, and cigarette smoke. The effects of various

[0008] Air pollutants can be intensified in the presence of other air pollutants and under the influence of UV radiation.

[0009] It is known that the toxicity of gaseous air pollutants, such as sulfur dioxide, ozone, and nitrogen oxides, is particularly related to their initiator activity for free radicals, which occurs when...

[0010] Free radicals cause damage to living organisms. They 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 cause hair damage, which can manifest, for example, as...

[0011] A reduction in shine, texture, and / or fading of the hair color becomes visible.

[0012] Particles are a complex mixture containing metals, minerals, organic toxins, and / or biological materials. They, too, can promote the formation of free radicals.

[0013] Furthermore, changing consumer preferences regarding specific hair textures are often linked to recurring chemical treatments of the hair. For example, hair coloring puts stress on the hair, which may necessitate special, intensive care.

[0014] The prior art describes organosilicon compounds from the group of silanes, which comprise at least one hydroxyl group and / or a hydrolyzable group. Due to the

[0015] Due to the presence of hydroxyl groups and / or hydrolyzable groups, silanes are reactive substances that hydrolyze, oligomerize, or polymerize in the presence of water. The oligomerization or polymerization of silanes initiated by the presence of water ultimately leads to the formation of a film on a keratinous material, which can provide a protective effect.

[0016] There is a need for a product that can reduce or prevent the harmful effects of air and water pollution on a keratinous material, especially hair, or the damaging effects of hair treatments on a keratinous material, especially hair.

[0017] The objective of the present invention is to provide a product with an improved care and / or protective effect.

[0018] This task is solved by a cosmetic agent for the treatment of a keratinous material, comprising

[0019] a) at least one organic silicon compound and

[0020] b) an anionic, nonionic and / or amphoteric surfactant.

[0021] 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.

[0022] 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.

[0023] The cosmetic agent for treating a keratinous material contains, as its first essential component, at least one organic silicon compound. Preferred organic

[0024] Silicon compounds are selected from silanes containing one, two or three silicon atoms, wherein the organic silicon compound includes one or more hydroxyl groups and / or hydrolyzable groups per molecule.

[0025] 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

[0026] Silicon atoms.

[0027] 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. In organic silanes, some of the hydrogen atoms may also be replaced by hydroxyl groups.

[0028] The agent for treating keratinous material contains at least one organic ingredient.

[0029] Silicon compound preferably 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.

[0030] In a particularly preferred embodiment, 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 further comprises one or more basic groups and one or more hydroxyl groups or hydrolyzable groups per molecule.

[0200] Even the addition of small amounts of water leads to hydrolysis of organic silicon compounds with at least one hydrolyzable group. The hydrolysis products and / or organic

[0201] Silicon compounds with at least one hydroxyl group can react with each other in a condensation reaction. Therefore, 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 organic silicon compounds with at least one hydroxyl group and their condensation products may be present in the product.

[0202] A condensation product is understood to be a product formed by the reaction of at least two organic silicon compounds, each with at least one hydroxyl group or

[0203] Hydrolyzable groups are formed per molecule through the elimination of water and / or an alkanol. The condensation products can be, for example, dimers, but also trimers or oligomers, with the condensation products existing in equilibrium with the monomers. Depending on the amount of water used or consumed in the hydrolysis, the equilibrium shifts from monomeric organic silicon compounds to the condensation product.
