Abstract:
A cosmetic or pharmaceutical composition which comprises at least one crosslinked, water-soluble or water-dispersible polyurethane ofA) at least one water-soluble or water-dispersible polyurethane prepolymer containing terminal isocyanate groups ofa) at least one compound having a molecular weight in the range from 56 to 300 which contains two active hydrogen atoms per molecule,b) at least one polymer containing two active hydrogen atoms per molecule,c) at least one compound which contains two active hydrogen atoms and at least one ionogenic or ionic group per molecule,d) at least one diisocyanate,B) at least one polymer containing groups which are reactive toward isocyanate groups, chosen from hydroxyl, and primary and secondary amino and/or carboxyl groups, where the polymer B) comprises, in copolymerized form,e) at least one .alpha.,.beta.-ethylenically unsaturated monomer which additionally contains at least one group which is reactive toward isocyanate groups per molecule,f) optionally at least one .alpha.,.beta.-ethylenically unsaturated monomer which is chosen from esters of .alpha.,.beta.-ethylenically unsaturated mono- and/or dicarboxylic acids with C.sub.1 - to C.sub.22 -alkanols, amides of .alpha.,.beta.-ethylenically unsaturated mono- and/or dicarboxylic acids with mono- and di-C.sub.1 - to C.sub.22 -alkylamines, esters of vinyl alcohol and allyl alcohol with C.sub.1 to C.sub.40 -monocarboxylic acids, vinyl ethers, aromatic vinyl compounds, vinyl halides, vinylidene halides, C.sub.2 - to C.sub.8 -monoolefins, nonaromatic hydrocarbons having at least 2 conjugated double bonds and mixtures thereof,g) optionally at least one .alpha.,.beta.-ethylenically unsaturated monomer which is chosen form N-vinylamides, N-vinyllactams, primary amides of .alpha.,.beta.-ethylenically unsaturated monocarboxylic acids, vinyl- and allyl-substituted heteroaromatic compounds and mixtures thereof,h) optionally at least one further monomer containing a free-radically polymerizable, .alpha.,.beta.-ethylenically unsaturated double bond and at least one ionogenic or ionic group per molecule,or a salt thereof.
