Cosmetic composition comprising a modified alpha-alkoxysilane

摘要

The invention relates to a cosmetic composition, in particular a composition for making up and/or caring for keratin materials, preferably a nail makeup, comprising the compound of chemical formula (I) below: (I) in which: a and b independently represent an integer between 0 and 20; R1, R2, R11 and R12 independently represent an ethoxy group, a group (C1-C20)alkyl optionally substituted with an amino group; R3, R4, R5, R6, R7, R8, R9 and R10 independently represent a hydrogen atom or a group (C1-C10)alkyl; X1 and X2 independently represent a carboxyl, carbamate, amide, carbonate, ureido or sulfonate group, an oxygen atom or a NH group; Y represents a hydrocarbon-based group comprising from 2 to 800 carbon atoms, the said hydrocarbon-based group being a linear or branched divalent group, bearing one or more aromatic or non-aromatic rings. The invention also relates to a cosmetic process, characterized in that it comprises at least one step which consists in applying a cosmetic composition as above defined to keratin materials.;
