Description

Washing composition of keratin materials based on water-soluble organic silicon compounds Field of the invention The present invention relates, in general, to aqueous washing compositions of keratin materials, and in particular of hair and / or hair the skin, which consists of organic silicon compounds soluble in water, as well as the washing procedures in which these compositions are used. It is known that the introduction of cosmetically active organic compounds such as cationic polymers and silicones in cosmetic detergent compositions such as shampoos, gives these compositions detangling properties, provide flexibility and lightness, to washed hair. However, the "combing" properties, characterized by an effect of maintaining the body and disciplining the hair, are not enough and do not resist washing the hair with a classic shampoo. It is also known to use polymer compounds rendered partially soluble in water. Thus, certain polymeric compounds can be used in water without the addition of any co-solvent. In this case, the limitation lies in the fact that these polymeric compounds are partially, completely, eliminated by rinsing the hair. Consequently, the effect due to REF.130450 polymeric compounds is very limited after rinsing. In the end, this limits the effect of the rinse treatments (shampoo, post-shampoo) but also reduces the interest of such compositions used in non-rinsing mode (lacquers, foams, folding lotions, etc.) as far as possible. which the user loses the effect acquired by the treatment when washing the hair. Efforts have therefore been made to find compounds for the formulation of cosmetic compositions which are usable in water and which have a remanence of their effect when the hair is rinsed. Thus, U.S. Patent No. 4,344,763 (GILLETTE) discloses cosmetic compositions that consist of an organosiloxane monomer, such as an aminoalkylalkoxysilane and an organic titanate in solution in an alcohol. Patent EP-159, 28 describes a hair permanent and fortification composition containing an alkyl trialkoxy silane, and FR-2 029, 696 describes a method of manufacturing Ti hair fixing product containing an organic resin consisting of the total or partially neutralized acid groups by means of silicon compounds or ganics that enclose amino radicals. The compositions and products described in these documents do not correspond to washing compositions and in particular for washing the hair, such as shampoos. There is thus a need for a detergent cosmetic composition, in particular for the washing of the hair, which is essentially aqueous and which makes it possible to obtain body, maintenance and texture effects of the hair which is very marked and remaining to the cycles of hair. washing completely maintaining effects of treatment of the hair. The subject of the present invention is therefore aqueous cosmetic detergent compositions for the washing of keratin materials, in particular shampoos, which give the hair a long-lasting combing effect and a pleasant touch and in particular pronounced body, maintenance and texture effects. and remnants to wash cycles. The applicant has noted, surprisingly, that it was possible to formulate washing compositions of keratin materials, particularly shampoos, having the desired properties, using in these compositions organic compounds of silicon, soluble in water, consisting of 1 to 3 silicon atoms, at least one basic chemical group and at least two hydrolysable or hydroxyl groups per molecule.
