Abstract
A transparent and optionally colored solid cosmetic composition comprising, in a physiologically acceptable medium, at least one odorous substance in an amount effective for scenting a cosmetic substrate and a liquid fatty phase comprising at least one polymer, chosen from: (1) polymers with a weight-average molecular mass ranging from 1,000 to 30,000, comprising a) a polymer backbone having hydrocarbonaceous repeat units provided with at least one heteroatom and b) at least one fatty chain chosen from pendant and end fatty chains, where the at least one fatty chain is optionally functionalised; comprises from 12 to 120 carbon atoms; and is bonded to at least one of the repeat units; and (2) polyamides with a weight-average molecular mass ranging from 1,000 to 30,000, comprising a) a polymer backbone comprising amide repeat units and b) optionally at least one fatty chain chosen from pendant and end fatty chains, where the at least one fatty chain is optionally functionalised; comprises from 12 to 120 carbon atoms; and is bonded to at least one of the amide units.
