Patent ID: 8790625

Claim:
A composition comprising, in a cosmetically or pharmaceutically acceptable medium, at least one polycondensate obtained by reaction of 10 to 30 wt. %, relative to the total weight of the polycondensate, of at least one polyol which is a linear, branched or cyclic hydrocarbon, saturated or unsaturated, having 3 to 18 carbon atoms and 3 to 6 hydroxyl groups (OH), optionally having one or more ether groups; of 30 to 80 wt. %, relative to the total weight of the polycondensate, of at least one saturated, linear, branched and/or cyclic, non-aromatic monocarboxylic acid of formula RCOOH, in which R is a saturated, linear, branched and/or cyclic hydrocarbon radical, having 5 to 31 carbon atoms; of 0.1 to 10 wt. %, relative to the total weight of the polycondensate, of at least one aromatic monocarboxylic acid of formula R′COOH, in which R′ is an aromatic hydrocarbon radical, containing 6 to 10 carbon atoms; said radical R′ can optionally be substituted with 1 to 3 saturated or unsaturated, linear, branched and/or cyclic alkyl radicals, which have 1 to 32 carbon atoms; and of 5 to 40 wt. %, relative to the total weight of the polycondensate, of at least one polycarboxylic acid, saturated or unsaturated, aromatic, linear, branched and/or cyclic, having at least 2 carboxyl groups COOH and/or a cyclic anhydride of said polycarboxylic acid, wherein the ratio of the number of moles of aromatic monocarboxylic acid to the number of moles of non-aromatic monocarboxylic acid is between 0.08 and 0.70.
