Patent ID: 7153517

Claim:
Cosmetic composition comprising at least one liquid fatty phase comprising at least one anhydrous solvent selected from the group consisting of hydrocarbon oils, siliconized oils and mixtures thereof, structured by at least one liquid crystal polymer, wherein the liquid crystal polymer is thermotropic and soluble in the anhydrous solvent and comprises: a main macromolecular chain, thermotropic mesogenic groups grafted onto the macromolecular chain, with a degree of grafting of at least 10%, said polymer having a vitreous transition temperature T g lower than 15° C. and a clarification temperature T cl higher than 45° C., and exhibiting a phase transition between an ordered mesomorphic phase (S2) with at least two dimensions and a poorly ordered mesomorphic phase (S1) with one dimension with a transition temperature T S2 / S1 higher than 25° C. and equal to or lower than 40° C.
