Patent ID: 7144582

Claim:
A structured cosmetic composition comprising: (i) at least one continuous liquid fatty phase, wherein said at least one continuous liquid fatty phase is structured with a sufficient amount of at least one polymer of formula (I) and mixtures thereof: in which: n is an integer which represents the number of amide units such that the number of ester groups present in said at least one structuring polymer ranges from 10% to 50% of the total number of all said ester groups and all said amide groups comprised in said at least one structuring polymer; R 1 , which are identical or different, are each chosen from alkyl groups comprising at least 4 carbon atoms and alkenyl groups comprising at least 4 carbon atoms; R 2 , which are identical or different, are each chosen from C 4 to C 42 hydrocarbon-based groups with the proviso that at least 50% of R 2 are chosen from C 30 to C 42 hydrocarbon-based groups; R 3 , which are identical or different, are each chosen from organic groups comprising atoms chosen from carbon atoms, hydrogen atoms, oxygen atoms and nitrogen atoms with the proviso that R 3 comprises at least 2 carbon atoms; and R 4 , which are identical or different, are each chosen from hydrogen atoms, C 1 to C 10 alkyl groups and a direct bond to group chosen from R 3 and another R 4 such that when said at least one group is chosen from another R 4 , the nitrogen atom to which both R 3 and R 4 are bonded forms part of a heterocyclic structure defined in part by R 4 —N—R 3 , with the proviso that at least 50% of all R 4 are chosen from hydrogen atoms; (ii) at least one amphiphilic compound chosen from amphiphilic compounds which are liquid at room temperature and have an HLB value of less than 12; and (iii) at least one dyestuff, wherein said structured composition is in the form of a non-migrating, wax-free solid, and wherein said at least one continuous liquid fatty phase, said at least one polymer, said at least one amphiphilic compound, and said at least one dyestuff form a physiologically acceptable medium.
