Patent ID: 7357921

Claim:
A method for conditioning the surface of the hair comprising: obtaining a composition comprising at least one monomer capable of polymerizing by anionic polymerization in the presence of a nucleophilic agent in a cosmetically acceptable medium; and applying the composition to the surface of the hair in the presence of a nucleophilic agent capable of initiating the anionic polymerization; wherein the at least one monomer is a monomer of formula: wherein: R 1 and R 2 denote, independently of each other: a hydrogen atom; a saturated or unsaturated, linear or branched hydrocarbon-based radical comprising from 4 to 20 carbon atoms; polysiloxane residue; a polyoxyalkylene group; or OR, COOR, COR, SH, SR and OH; wherein any R denotes a C1-C10 alkyl or C1-C10 mono- or polyfluoroalkyl radical; and R′ 3 is a non-electron-withdrawing or electron-withdrawing group, further defined as: a hydrogen atom a saturated or unsaturated, linear, branched or cyclic hydrocarbon-based radical containing from 4 to 20 carbon atoms; a polysiloxane residue: a polyoxyalkylene group; or a linear or branched alkenyl radical, linear or branched alkynyl radical, or mono- or polyfluoroalkyl group containing 2 to 10 carbon atoms; and wherein the at least one monomer forms part or all of a total monomer concentration of between 0.1% and 10% by weight.
