Claim:
A cosmetic preparation comprising a cationic polymer which is produced by the process comprising: polymerizing in a polymerization vessel from 3 to 30% by weight of at least one quaternary nitrogen-comprising free-radically polymerizable monomer (a1) and/or a direct preproduct (a2) thereof, from 0 to 15% by weight of one or more first additional free-radically polymerizable monomer (c) having a solubility in water above 60 g/l at 25° C. and from 0 to 15% by weight of one or more second additional free-radically polymerizable monomer (d) having a solubility in water of less than 60 g/l at 25° C., in the presence of from 70 to 97% by weight of at least one polyether-comprising compound (b), wherein the at least one quaternary nitrogen-comprising free-radically polymerizable monomer (a1) and/or a direct preproduct (a2) thereof is at least one selected from the group consisting of 3-methyl-1-vinylimidazolium chloride, 3-methyl-1-vinylimidazolium methylsulfate and N,N-dimethyl-N,N-diallylammonium chloride, the polyether-comprising compound (b) is a polymer, copolymer or block copolymer of at least one compound selected from the group consisting of ethylene oxide and propylene oxide, the water content in the reaction mixture during the polymerization is less than 10% by weight; if the polymerization vessel comprises the preproduct (a2), said preproduct (a2) is converted at least partially into a compound comprising quaternary nitrogen (a2′) subsequently to or during said polymerizing; the molar ratio of the sum of the at least one quaternary nitrogen-comprising free-radically polymerizable monomer (a1), the compound comprising quaternary nitrogen (a2′) and the one or more first additional free-radically polymerizable monomer (c) to the sum of the one or more second additional free-radically polymerizable monomer (d) is at least 2 to 1; and the percentages by weight of the at least one quaternary nitrogen-comprising free-radically polymerizable monomer (a1) and/or a direct preproduct (a2) thereof, the at least one polyether-comprising compound (b), the one or more first additional free-radically polymerizable monomer (c) and the one or more second additional free-radically polymerizable monomer (d) add up in each case to 100% by weight.
