    Abstract: The invention relates to the use of polymers in cosmetic preparations for hair. Said polymers can be obtained by (i) radically initiated copolymerisation of monomer mixtures consisting of (a) at least one cationic monomer or quaternisable monomer (b), optionally a water-soluble monomer, (c) optionally another radically copolymerisable monomer, (d) at least one monomer acting as a cross-linking agent and having at least two ethylenically unsaturated, non-conjugated double bonds, and (e) at least one regulator; and by (ii) subsequent quaternisation or protonation of the polymers, provided that a non-quaternised or only partially quaternised monomer is used as monomer (a).

    Abstract: The invention relates to acrylate polymers comprising a K-value ranging from 10 to 60, which can be obtained by the radical polymerization of: 30 to 99 wt. % of tert-butyl acrylate and/or tert-butyl methacrylate designated as monomer A; 1 to 28 wt. % of acrylic acid and/or methacrylic acid designated as monomer B, and; 0 to 60 wt. % of a radically copolymerizable monomer or of a radically copolymerizable monomer mixture designated as monomer C, whereby at least one of monomers C yields a homopolymer with a glass-transition temperature lower than 30 ~C, with the provision that the wt. %'s total 100. The radical polymerization is carried out in the presence of alkane thiols with a C chain length of C 14 to C 22. The invention also relates to acrylate polymers comprising a K-value ranging from 10 to 60, which can be obtained by the radical polymerization of: 30 to 99 wt. % of tert-butyl acrylate and/or tert- butyl methacrylate designated as monomer A; 1 to 28 wt. % of acrylic acid and/or methacrylic acid designated as monomer B, and; 0 to 60 wt. % of a radically copolymerizable monomer or of a radically copolymerizable monomer mixture designated as monomer C, whereby at least one of monomers C yields a homopolymer with a glass-transition temperature lower than 30 ~C, with the provision that the wt. %'s total 100. The radical polymerization is carried out in the presence of alkane thiols with a C chain length of C 10 to C 22 followed by a hydrogen peroxide treatment. The invention also relates to the use of these acrylate polymers as film formers as well as to their use in cosmetic preparations.

    Abstract: Use of polymerizate of ethylenic unsaturated anionic monomer, optionally in the form of an aqueous dispersion, obtained by radical polymerization of the monomer in aqueous medium, for modifying the rheology of aqueous, alcoholic or aqueous/alcoholic cosmetic or dermatological compositions. Use of polymerizate of ethylenic unsaturated anionic monomer, optionally in the form of an aqueous dispersion, obtained by radical polymerization of the monomer in aqueous medium and the polymerization is carried out in the presence of at least one polymer (A) and at least one polymer (B), where the polymer (A) is a graft polymerizate of vinylacetate and/or vinyl propionate on polyethylene glycol or polyalkylene glycol unilaterally or bilaterally attached at terminals with alkyl-, carboxyl- or amino groups or polypropylene glycol, polyalkylene glycol, unilaterally or bilaterally with alkyl, carboxyl or amino group terminally attached polyethylene glycol or polypropylene glycol or copolymerisate from alkyl polyalkylene glycol(meth)acrylate and (meth)acrylic acid; and the polymer (B) is at least partially hydrolyzed copolymerisate of vinyl alkyl ether and maleic acid anhydride that is present at least partially in its salt form, water-soluble starch such as cationically modified starch, anionically modified starch, degraded starch or maltodextrin, anionic copolymer such as homo- and copolymerisate of anionic monomer, copolymerisate from anionic and cationic and optionally neutral monomer, where a portion of monopolymerizate anionic monomer is greater than the cationic monomer and copolymerisate of at least one anionic monomer and at least one monomer of the ester of anionic monomer with monovalent alcohol, styrene, N-vinylpyrrolidone, N-vinylcaprolactam, N-vinylimidazole, N-vinyl formamide, (meth)acrylamide, vinylacetate and vinyl propionate, cationic copolymer of nonionic monoethylenic unsaturated monomer and cationic monoethylenic unsaturated monomer, where the portion of the cationic group is greater than the portion of the anionic group, for modifying the rheology of aqueous, alcoholic or aqueous/alcoholic cosmetic or dermatological compositions. Independent claims are included for a hair cosmetic agent, a skin cosmetic agent and a dermatological agent comprising at least one polymerizate of ethylenic unsaturated anionic monomer.
