    摘要： The invention relates to the use of polymers in cosmetic preparations. These polymers are comprised of 30-65 % by weight of N-vinyl caprolactam, 35-65 % by weight of a monomer mixture consisting of N-vinyl imidazole and vinyl pyrrolidone, whereby the weight ratio of N-vinyl imidazole to vinyl pyrrolidone ranges from 0.085 to 0.30, and 0-15 % by weight of a nitrogen-containing quaternizable monomer (A), which is different from N-vinyl imidazole, whereby the sum of monomer (A) and N-vinyl imidazole is less than 18 % by weight.

    摘要： The invention relates to a method for reducing the quantity of residual monomers in aqueous dispersions of polymers by re-treatment with an initiator system which essentially comprises the following: a) 0.001 to 5 wt. % (in relation to the total quantity of monomers used to produce the polymer dispersion) of a1) an oxidising agent R?1OOH, R1¿ being hydrogen, a C¿1?- to C8-alkyl group or a C6- to C12-aryl group and/or a2) a compound which releases hydrogen peroxide in an aqueous medium and b) 0.005 to 5 wt. % (in relation to the total quantity of monomers used to produce the polymer dispersion) of b1) an α-hydroxycarbonyl compound of formula (I), wherein R?2 and R3¿, independently of each other, mean hydrogen and/or a C¿1?- to C12- alkyl group which can contain functional groups and/or be olefinically unsaturated and R?2 and R3¿ optionally form a ring structure with methylene groups and said ring structure can contain functional groups and/or be olefinically unsaturated and/or b2) a compound which releases α-hydroxycarbonyl compounds of this type in an aqueous medium and c) advantageously, catalytic quantities of a multivalent metal ion which can occur in several valence states.
