The invention concerns a physiologically acceptable composition, in particular cosmetic, containing at least a liquid fatty phase comprising at least a volatile substance, the liquid fatty phase being structured by at least a polymer with average molecular mass by weight not more that 100,000, including: a) a polymeric skeleton, having hydrocarbon repeat units provided with at least a heteroatom, and b) pendant and/or terminal fatty chains optionally functionalised, having 1 to 120 carbon atoms and bound to said units, the liquid fatty phase and the polymer forming a physiologically acceptable medium. Said composition is in particular in the form of a lipstick, whereof the application results in a bright deposit, with long lasting resistance and no significant transfer.
L'invention se rapporte ~ une composition physiologiquement acceptable, notamment cosm~tique, contenant au moins une phase grasse liquide comprenant au moins un solvant volatil, la phase grasse lquide ~tant structur~e par au moins un polymre de masse mol~culaire moyenne en poids inf~rieur ou ~gal ~ 100 000, comportant a) un squelette polym~rique, ayant des motifs de r~p~tition hydrocarbon~s pourvus d'au moins un h~t~roatome, et b) des cha¹nes grasses pendantes et/ou terminales ~ventuellement fonctionnalis~es, ayant de 6 ~ 120 atomes de carbone et ~tant li~es ~ ces motifs, la phase grasse liquide et le polymre formant un milieu physiologiquement acceptable. Cette composition se pr~sente notamment sous forme d'un stick de rouge ~ lvres, dont l'application conduit ~ un d~pÙt brillant, de bonne tenue dans le temps et sans transfert, remarquable.
