Abstract

The disclosure is directed to a process of conditioning hair in which a cosmetic composition is applied to the hair, which composition contains a polymer formed by(i) the free-radically initiated copolymerization of monomer mixtures of(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-radical copolymerizable monomer, and(ii) subsequent quaternization of the polymer if the monomer (a) is a non-quaternized monomer.
