  • Fluid aqueous antisun composition based on a superabsorbent polymer and a crosslinked copolymer of methacrylic acid and of a C1-C4 alkyl acrylate
    Patent number: 9925132
    Abstract: The present invention relates to a fluid composition, characterized in that it comprises, in a cosmetically acceptable aqueous support: (a) at least one fatty phase; (b) a photoprotective system capable of screening out UV radiation; (c) at least one superabsorbent polymer; (d) at least one crosslinked copolymer of methacrylic acid and of a C1-C4 alkyl acrylate. Another subject of the present invention lies in the use of the combination of a superabsorbent polymer and of a crosslinked copolymer of methacrylic acid and of an alkyl acrylate in a fluid composition comprising, in a cosmetically acceptable aqueous support, at least one photoprotective system capable of screening out UV radiation, as a freshness agent and/or as a stabilizer for the composition.
