Description

The present invention relates to cosmetic agents for the treatment of a keratinous material, wherein the agent comprises two organic silicon compounds and an anionic, nonionic or amphoteric surfactant, and the use of the cosmetic agent. External stress on hair from chemical substances of numerous different sources presents challenges for the development of cosmetic care 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. 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 in 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 referred to as "oxidative damage." Free radicals can also damage hair, which may manifest as a reduction in shine and manageability, and/or fading of hair color. Particles are a complex mixture containing metals, minerals, organic toxins, and/or biological materials. They, too, can promote the formation of free radicals. 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. 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. From the FR 3060326 A1 A cosmetic hair treatment product is known which contains two organic silicon compounds, two different anionic surfactants, a non-ionic surfactant and an amphoteric surfactant. From the FR 3 044 904 A1 A cosmetic hair treatment product is known which contains two organic silicon compounds, two different anionic surfactants, a non-ionic surfactant and an amphoteric surfactant. 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. The objective of the present invention is to provide a product with an improved care and/or protective effect. This task is solved by a cosmetic agent for the treatment of a keratinous material, comprising a) at least one organic silicon compound and b) an anionic, nonionic and/or amphoteric surfactant, wherein the agent for treating a keratinous material contains - based on the total weight of the agent for treating a keratinous material: 0.5 to 3 wt% of at least one first organic silicon compound 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 3.2 to 7 wt% of at least one second organic silicon compound selected from the group consisting of methyltrimethoxysilane, methyltriethoxysilane, ethyltrimethoxysilane, ethyltriethoxysilane, propyltrimethoxysilane, propyltriethoxysilane, hexyltrimethoxysilane, hexyltriethoxysilane, octyltrimethoxysilane, octyltriethoxysilane, dodecyltrimethoxysilane, dodecyltriethoxysilane, octadecyltrimethoxysilane and octadecyltriethoxysilane. 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. 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. The cosmetic agent for treating a keratinous material contains at least two organic silicon compounds as the first essential component of the invention. 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. According to IUPAC rules, the term silane refers to a group of
