Water-soluble polymers having a water-soluble backbone and side units having in water a lower critical solution temperature, LCST, the polymers being obtainable by free-radical precipitation polymerization of water-soluble monomers and of macromonomers comprising a unit with an LCST whose heat-induced demixing temperature in aqueous solution is from 5 to 40° C. for a concentration by mass in water of 1% of the said unit. Also described is a process for preparing these polymers by free-radical precipitation polymerization, and aqueous compositions containing these polymers and the use of these polymers and compositions, especially in cosmetics, for the cleansing and/or making up and/or care and/or antisun protection of keratin materials. |
