Patent ID: 8691193

Claim:
A composition comprising, in a cosmetically or pharmaceutically acceptable medium, at least one polycondensate obtained by reacting: from 18% to 25% by weight, relative to a total weight of the polycondensate, of at least one polyol that is a saturated linear or branched hydrocarbon-based compound comprising 3 to 18 carbon atoms and 3 to 6 hydroxyl groups; from 10% to 35% by weight, relative to the total weight of the polycondensate, of at least one non-aromatic monocarboxylic acid given by the formula RCOOH, in which R is a saturated linear or branched hydrocarbon-based radical comprising 5 to 31 carbon atoms; from 25% to 50% by weight, relative to the total weight of the polycondensate, of at least one aromatic monocarboxylic acid selected from the group consisting of benzoic acid, o-toluic acid, m-toluic acid, p-toluic acid, 1-naphthoic acid, 2-naphthoic acid, 4-tert-butylbenzoic acid, 1-methyl-2-naphthoic acid, and 2-isopropyl-1-naphthoic acid; and from 12% to 20% by weight, relative to the total weight of the polycondensate, of at least one polycarboxylic acid anhydride of a polycarboxylic acid selected from the group consisting of decanedioic acid, dodecanedioic acid, cyclopropanedicarboxylic acid, cyclohexanedicarboxylic acid, cyclobutanedicarboxylic acid, naphthalene-1,4-dicarboxylic acid, naphthalene-2,3-dicarboxylic acid, naphthalene-2,6-dicarboxylic acid, suberic acid, oxalic acid, malonic acid, succinic acid, phthalic acid, terephthalic acid, isophthalic acid, pimelic acid, sebacic acid, azelaic acid, glutaric acid, adipic acid, fumaric acid, maleic acid, cyclohexanetricarboxylic acid, trimellitic acid, 1,2,3-benzenetricarboxylic acid, 1,3,5-benzenetricarboxylic acid, butanetetracarboxylic acid, pyromellitic acid, phthalic anhydride, trimellitic anhydride, maleic anhydride, and succinic anhydride.
