Abstract
The invention relates to emulsions and foaming compositions containing a polymer comprising water-soluble units and units with an LCST, especially for cosmetic uses. According to the invention, a polymer whose units with an LCST have in water a demixing temperature of from 5 to 40° C. at a concentration of 1% by mass are used in these compositions, to lower the surface tension or interface tension of water and to promote the production of foam or emulsion.
Claims43
Use of a polymer comprising water-soluble units and units with an LCST, the units with an LCST having in water a demixing temperature of from 5 to 40° C. at a concentration of 1% by mass in water, to lower the surface tension or the interface tension of water.
Use of a polymer comprising water-soluble units and units with an LCST, the units with an LCST having in water a demixing temperature of from 5 to 40° C. at a concentration of 1% by mass in water, to manufacture a foam.
Use of a polymer comprising water-soluble units and units with an LCST, the units with an LCST having in water a demixing temperature of from 5 to 40° C. at a concentration of 1% by mass in water, to manufacture a foam, also comprising a foaming surfactant at a concentration of less than or equal to 5% by mass.
Use of a polymer comprising water-soluble units and units with an LCST, the units with an LCST having in water a demixing temperature of from 5 to 40° C. at a concentration of 1% by mass in water, to manufacture an emulsion free of additional emulsifying surfactant or containing an additional emulsifying surfactant at a concentration of less than or equal to 1% by mass.
Foaming composition comprising an aqueous phase containing a polymer comprising water-soluble units and units with an LCST, the units with an LCST having in water a demixing temperature of from 5 to 40° C. at a concentration of 1% by mass in water.
Oil-in-water emulsion comprising an aqueous phase and an oily phase dispersed in the aqueous phase, in which the aqueous phase comprises a polymer comprising water-soluble units and units with an LCST, the units with an LCST having in water a demixing temperature of from 5 to 40° C. at a concentration of 1% by mass in water.
Water-in-oil-in-water emulsion comprising a water-in-oil emulsion dispersed in an outer aqueous phase, in which the outer aqueous phase comprises a polymer comprising water-soluble units and units with an LCST, the units with an LCST having in water a demixing temperature of from 5 to 40° C. at a concentration of 1% by mass in water.
Cosmetic process for cleansing and/or removing make-up from the skin, the scalp and/or the hair, characterized in that the composition of the invention is applied to the skin, to the scalp and/or to the hair, in the presence of water, and the foam formed and the soiling residues are removed by rinsing with water.
