| 摘要 |
The invention relates to a cosmetic process for caring for or making up keratin materials, comprising either the topical application to the keratin materials of an anhydrous (extemporaneous) mixture of a cosmetic composition comprising a maleic anhydride acrylic polymer and of an aminoalkoxysilane compound (I), or the sequential application to the keratin materials of an anhydrous cosmetic composition comprising a maleic anhydride acrylic polymer and of an aminoalkoxysilane compound (I), wherein said maleic anhydride acrylic polymer is obtained by polymerization of: (a) 50% to 90% by weight, of the total weight of monomers, of isobornyl (meth)acrylate, (b) 1% to 50% by weight of maleic anhydride and (c) 0 to 49% by weight of additional (meth)acrylate monomer, said aminoalkoxysilane being of formula (I): R‑NH‑R1Si(OR2)z(R3)x (I) in which: R1 is a C1‑C20 hydrocarbon-based divalent group, R = H or a C1‑C4 alkyl group, R2 and R3 are an alkyl group comprising from 1 to 6 carbon atoms, z denotes an integer ranging from 1 to 3, and x denotes an integer ranging from 0 to 2, with z+x=3. Uses: skin-tensioning agent, makeup, hair fixing. |
