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 cosmetic product containing at least one water-soluble copolymer which is obtained by radical copolymerization of acrylamide and/or methacrylamide and other water-soluble α,ß-ethylenically unsaturated compounds which are copolymerizable therewith, optionally in the presence of a water-soluble polymeric graft base.
摘要:
The invention relates to cosmetic preparations, particularly for hair cosmetic applications, containing copolymers based on N-vinyl lactams and N-vinyl heterocyclic compounds.
摘要:
The invention relates to cosmetic and pharmaceutical substances containing at least one polyelectrolyte complex that comprises a copolymer with catiogenic groups based on vinylimidazole and a polymer which contains acid groups. The invention further relates to the use of said polyelectrolyte complexes.
