Title: COMPOSITION COMPRISING A SILANE AND A POLYSACCHARIDE BEARING HYDROPHOBIC GROUPS
Abstract:
The present invention relates to a cosmetic composition comprising at least one polysaccharide bearing hydrophobic groups and at least one silane corresponding to formula (I) below and/or oligomers thereof: R1Si(OR2)z(R3)x(OH)y (I) in which: R1 is a linear or branched, saturated or unsaturated C1 -C22 hydrocarbon-based chain, C3-C40 cycloalkyl or C6-C30 aromatic; optionally substituted with a hydroxyl group, a thiol group, an aryl group (more particularly benzyl), which is substituted or unsubstituted; R1 possibly being interrupted with a heteroatom (O, S or NH) or a carbonyl group (CO); R2 and R3, which may be identical or different, represent a linear or branched alkyl group comprising from 1 to 6 carbon atoms; y denotes an integer ranging from 0 to 3; and z denotes an integer ranging from 0 to 3; and x denotes an integer ranging from 0 to 2; with z+x+y=3, the silanes of formula (I) and/or oligomers thereof being present in an active material content ranging from 2% to 20% by weight relative to the total weight of the composition.
