COSMETIC COMPOSITION COMPRISING AN UREA OR AMIDE BASED 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: m represents an integer equal to 0 or 1; n represents an integer between 2 and 8; R1 represents a group (C1-C20)alkyl or an aryl group, or alternatively, when m is equal to 0, R1 may also represent a carbonyl; R2 and R3 represent an ethoxy group or a group (C1-C20)alkyl, optionally substituted with an amino group; Y represents a polyurea or a polyurethane or alternatively a hydrocarbon-based group comprising from 2 to 100 carbon atoms. The invention also relates to a cosmetic process, in particular a makeup or hair shaping process, preferably a process for making up keratin materials, in particular the nails and/or the hair, characterized in that it comprises at least one step which consists in applying a cosmetic composition as above defined to keratin materials.;

1. A cosmetic composition, comprising a compound of formula (I): where: m represents an integer of 0 or 1; n represents an integer of from 2 to 8; R1 represents a (C1-C20)alkyl group, an aryl group, or optionally a carbonyl group when m is 0; R2 and R3 represent an ethoxy group or a (C1-C20)alkyl group, optionally substituted with an amino group; and Y represents a polyurea, a polyurethane, or a hydrocarbon-based group comprising from 2 to 100 carbon atoms, wherein the hydrocarbon-based group is optionally a linear or branched monovalent or multivalent, optionally unsaturated group, and optionally bears one or more aromatic or non-aromatic cyclic groups, the carbon atoms are optionally substituted with one or more groups selected from the group consisting of an ethoxy group and an amino group, one or more of the carbon atoms are optionally independently replaced with
a nitrogen atom,a carbonyl group,a —SiO— group, ora polydimethylsiloxane group:where z is a number of from 1 to 20 and
the hydrocarbon-based group optionally forms with R1 one or more rings.
