Abstract
Cosmetic compositions comprising, in a cosmetically acceptable medium:(1) at least one film-forming polymer (A), wherein a film obtained by drying a mixture of said polymer (A) with ethanol or water, at room temperature and at a relative humidity of 50%, has a mechanical profile defined by at least:(i) a degree of elongation at break (&egr;r) of greater than or equal to 300%;(ii) a recovery at 300 seconds (R300) of greater than or equal to 45%; and(iii) if the recovery at 300 seconds (R300) is from 45% to 60%, then the elongation at break is less than or equal to 1300%; and(2) at least one crosslinked thickening polymer (B) comprising at least one (meth)acrylic acid monomeric, wherein said at least one polymer (B) is present in the composition in an amount ranging from at least 0.6% by weight, relative to the total weight of the composition.
