Abstract: 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 (extemporaneous) anhydrous mixture of a cosmetic composition comprising a maleic anhydride acrylic polymer and of an amino alkoxysilane compound (I); or the sequential application to the keratin materials of an anhydrous cosmetic composition comprising a maleic anhydride acrylic polymer and of an amino alkoxysilane compound (I), wherein said maleic anhydride acrylic polymer is obtained by polymerization of:(a) 50% to 90% by weight, relative to the total weight of monomers, of isobornyl (meth)acrylate (b) 1% to 50% by weight of maleic anhydride (c) 0% to 49% by weight of additional (meth)acrylate monomer; said amino alkoxysilane having the 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 represent 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.

Abstract: The invention relates to a copolymer resulting from the 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, (c) 0% to 49% by weight of additional (meth)acrylate monomer chosen from: (i) saturated or unsaturated and linear or branched C1-C20 alkyl (meth)acrylates, the alkyl being optionally interrupted by one or more nonadjacent heteroatoms chosen from O or S or by an NR group, R being a C1-C4 alkyl group, optionally substituted by a phenyl or furfuryl group; (ii) saturated C4-C8 cycloalkyl (meth)acrylates, the cycloalkyl being optionally interrupted by O or NH. The invention also relates to a composition comprising said copolymer in a physiologically acceptable medium.The invention also relates to a cosmetic method for caring for or making up the skin or the lips, comprising the topical application, to the skin or the lips, of a cosmetic composition comprising said copolymer.
