Abstract:
A method of lowering the surface tension or the interface tension of water in cosmetic compositions comprising at least one cosmetic or dermatological adjuvant, the method comprising adding a polymer comprising water-soluble units and units with an LCST, wherein the LCST units an have in water a demixing temperature of from 5 to 40° C. for a concentration of 1% by mass is used, the polymer being present in a concentration such that the gel point of the aqueous phase is from 5 to 40° C., to ensure the stability of the dispersions at temperatures from 4° C. to 50° C.
