Water-soluble polymers and their use in cosmetic and pharmaceutical compositions

A water-soluble polymer preparable by free-radical copolymerization of

• A) one or more macromonomers containing an end-group capable of polymerization, a hydrophilic moiety based on polyalkylene oxides, and a hydrophobic moiety which comprises hydrogen or a saturated or unsaturated, linear or branched, aliphatic, cycloaliphatic or aromatic (C1-C30)-hydrocarbon radical, wherein the macromonomers are in a proportion of 0.1 to 50 mol %, and
• B) one or more olefinically unsaturated comonomers wherein the comonomers are styrenesulfonic acid, acrylamidopropylmethylenesulfonic acid (AMPS), vinylsulfonic acid, vinylphosphonic acid, allylsulfonic acid, methallylsulfonic acid and salts thereof;
• esters of (meth)acrylic acid with aliphatic, aromatic or cycloaliphatic alcohols having a carbon number from 1 to 22;
• esters of (meth)acrylic acid with alkyl ethoxylates, open-chain and cyclic N-vinylamides (N-vinyllactams) having a ring size of from 4 to 9 atoms;
• N,N-dimethylacrylamide, N,N-diethylacrylamide, alkoxylated acrylamides and methacrylamides;
• 2-vinylpyridine;
• 4-vinylpyridine;
• vinyl acetate;
• glycidyl methacrylate, acrylonitrile;
• vinyl chloride;
• vinylidene chloride;
• tetrafluoroethylene and/or diallyldimethylammonium chloride (DADMAC).
