| titleOfInvention | Water-soluble or water-swellable polymers on the basis of salts of acryloyldimethyltaurine acid or the derivatives thereof, the production thereof and the use thereof as thickener, stabilizer and consistency agents |
| abstract | Polymers are described comprising a) one or more of the recurring structural units of the formula (1) where R1 is hydrogen, methyl or ethyl and A is C1-C8-alkylene, and Q+ is H+, NH4+, Li+, Na+, K+, 1/2 Ca++, 1/2 Mg++, 1/2 Zn++ or 1/3 Al+++, and the neutralization degree of the structural units of formula (1) is 50 to 100 mol-%, and b) one or more of the recurring structural units of the formula (2) where R1 and A are R1 and A from formula (1) and X+ is [HNR5R6R7]+, where R5, R6 and R7 can independently from each other be hydrogen, a linear or branched alkyl group with 1 to 22 carbon atoms, a linear or branched, simple or polyunsaturated alkenylene group with 2 to 22 carbon atoms, a C6-C22-alkylamidopropyl group, a linear monohydroxyalkyl group with 2 to 10 carbon atoms or a linear or branched dihyroxyalkyl group with 3 to 10 carbon atoms, and wherein at least one of the groups R5, R6 and R7 is not hydrogen, with the proviso that the molar ratio of the structural units of formula (1), where Q+ is NH4+, Li+, Na+, K+, Ca++, Mg++, Zn++ or Al+++, to the structural units of formula (2) is 97:3 to 55:45 and the formation concentration (CMC) < 15 g/l and c) of 0 to 8, preferably 0.01 to 5 wt.-% of cross-linking structural units, obtained from monomers with at least two olefinic double bonds. The polymers are suitable, for example, in an advantageous way as thickeners in cosmetic, dermatologic and pharmaceutical compositions. |
