    摘要： A fluid cosmetic composition with unusual rheologic characteristics has a formulation comprising 0.1 to 50% by weight of at least one fluid branched polymer obtained by simultaneous reaction from components A. B and C, where A is a linear polymer with a molecular weight Mw between 5000 and 50000 Da, provided with reactive functional groups X in a chain at a concentration between 0.1 and 50 mmol/g of polymer. B is a linear polymer with a molecular weight Mw between 10000 and 100000 Da, having terminal reactive functional groups of type Y capable of reacting with the functional group X in an addition or condensation reaction, and C is a molecule or linear oligomer (or a mixture thereof) with a molecular weight between 50 and 1000 Da, having a reactive functional group Y per molecule, capable of reacting with the functional group X in an addition or condensation reaction. The molar ratio of the functional groups of B and A is between 0.01 and 0.5 and the molar ratio of the functional groups of C and A is between 0.5 and 1.2. The reactive group X of A is capable of reacting with the reactive sites Y of B and C.

    摘要： The present invention relates to a cosmetic composition, which is preferably solid, comprising, in a physiologically acceptable medium:—a crosslinked polyurethane elastomer gel comprising a single crosslinked polyurethane elastomer (copolymer) or a mixture of at least two crosslinked polyurethane elastomers (copolymers), wherein said copolymer or said mixture of copolymers is obtained from a prepolymer having at least two hydroxyl groups and from a (poly)isocyanate and at least one solvent, in particular from a carboxylic acid dimer or trimer, from at least one polyol and from a diisocyanate, and—one or more pasty fatty substances chosen from the group consisting of (i) esters of polyol(s) and of a fatty acid dimer diacid, or of an ester thereof, (ii) hydrogenated castor oil esters, (iii) glycerol oligomer esters, in particular digylcerol esters, (iv) and mixtures thereof.
