Abstract
A composition suitable for topical application, which contains:a liquid fatty phase,at least one coloring agent,at least 2% by weight, with respect to the total weight of the composition, of a polymer which is dispersible in the liquid fatty phase, anda polymer which is soluble in the liquid fatty phase.In preferred embodiments, the composition may be provided in the form of a cast product or of a gel containing at least one coloring material, in particular pulverulent coloring material, a dispersion of polymer particles which are stabilized at the surface in a liquid fatty phase and a fat-soluble polymer of the vinylpyrrolidone copolymer type. In addition, according to the amount of polymer, it is possible to obtain, on the lips or skin, a supple film having notable transfer-free properties while being extremely comfortable. The invention also relates to the use of this dispersion in such a composition.
