US Patent No. 11,510,860 B2 (Stéphane Douezan, Alexandra Batista); L’Oréal, Paris, has patented a composition comprising:
• at least one or more polymers comprising monomer units of formulae (A) and (B) in which: R1, independently of one another, is chosen from alkyl or alkylene radicals, and at least 60% by weight of the R1 groups are behenyl radicals, the percentage by weight relating to the sum of all the R1 groups present in the polymer, and the weight ratio of the sum of all the hydroxyethyl acrylate units to the sum of all the acrylate units bearing the R1 group ranges from 1:30 to 1: 1 and the sum of the total of units A and B is at least 95% by weight of the total weight of the polymer, the polymer having a number-average molecular weight Mn ranging from 2000 to 9000 g/mol;
• one or more fatty acid esters of dextrin; and
• one or more UV-screening agents.
