Abstract:
A process of conditioning hair comprising applying to the hair a cosmetic hair composition comprising a polymer obtained by(i) free-radically initiated copolymerization of monomer mixtures comprising (a) from 1 to 99.99% by weight of a cationic monomer or quaternizable monomer, (b) from 0 to 98.99% by weight of a water-soluble monomer, (c) from 0 to 50% by weight of a further free-radically copolymerizable monomer, and (d) from 0.01 to 10% by weight of a bifunctional or polyfunctional, free-radically copolymerizable monomer, and (ii) subsequent quaternization of the polymer if the monomer (a) is a non-quaternized monomer, wherein the monomer (a) is an N-vinylimidazole derivative of the formula (I) where R1 to R3 are hydrogen, C1-C4-alkyl or phenyl, wherein said N-vinylimidazole derivative of the formula (I) may optionally be in a quaternized form,wherein the monomer (b) is N-vinyl-pyrrolidone, wherein said polymer acts on the hair as conditioning agent and wherein the cosmetic hair composition further comprises from 2 to 50% by weight of surfactants.
