The polyurethanes described above can also be used in combination with other hair polymers in the compositions. Such polymers are, in particular:
nonionic, water-soluble or water-dispersible polymers or oligomers, such as polyvinylcaprolactam, e.g.. Luviskol Plus (BASF), or polyvinylpyrrolidone and copolymers thereof, in particular with vinyl esters, such as vinyl acetate, e.g. Luviskol VA 37 (BASF); polyamides, e.g. based on itaconic acid and aliphatic diamines;
amphoteric or zwitterionic polymers, such as the octylacrylamide/methyl methacrylate/tert-butylaminoethyl methacrylate/2-hydroxypropyl methacrylate copolymers obtainable under the names Amphomer® (Delft National), and zwitterionic polymers, as are disclosed, for example, in German patent applications DE 39 29 973, DE 21 50 557, DE 28 17 369 and DE 37 08 451. Acrylamidopropyltrimethylammonium chloride/acrylic acid or
methacrylic acid copolymers and alkali metal and ammonium salts thereof are preferred zwitterionic polymers. Further suitable zwitterionic polymers are methacroylethylbetaine/methacrylate copolymers, which are commercially available under the name Amersette® (AMERCHOL);
anionic polymers, such as vinyl acetate/crotonic acid copolymers, as are available commercially, for example under the names Resyn® (NATIONAL STARCH), Luviset® (BASF) and Gafset® (GAF), vinylpyrrolidone/vinyl acrylate copolymers, obtainable, for example, under the trade name Luviflex® (BASF). A preferred polymer is the vinylpyrrolidone/acrylate terpolymer obtainable under the name Luviflex® VBM-35 (BASF), acrylic acid/ethyl acrylate/N-tert-butylacrylamide terpolymers, which are sold, for example, under the name Ultrahold® strong (BASF), and Luvimer® (BASF, terpolymer of t-butyl acrylate, ethyl acrylate and methacrylic acid), or
cationic (quaternized) polymers, e.g. cationic polyacrylate copolymers based on N-vinyllactams and derivatives thereof (N-vinylpyrrolidone, N-vinylcaprolactam etc.), and customary cationic hair-conditioning polymers, e.g. Luviquat® (copolymer of vinylpyrrolidone and vinylimidazolium methochloride), Luviquat® Hold (copolymer of quaternized N-vinylimidazole, N-vinylpyrrolidone and N-vinylcaprolactam), Merquat® (polymer based on dimethyldiallylammonium chloride), Gafquat® (quaternary polymers which arise by reacting polyvinylpyrrolidone with quaternary ammonium compounds), polymer JR (hydroxyethylcellulose with cationic groups), polyquaternium products (CTFA names) etc.;
nonionic, siloxane-containing, water-soluble or -dispersible polymers, e.g. polyether siloxanes, such as Tegopren® (Goldschmidt) or Belsil® (Wacker).
nonionic, water-soluble or water-dispersible polymers or oligomers, such as polyvinylcaprolactam, e.g..
