Abstract
This composition, containing in the conventional manner at least one wax, at least one thickening agent and at least one volatile organic solvent and optionally other conventional ingredients (fillers, pigments, vitamins, amino acids, etc.) is characterized in that it contains an aqueous solution of at least one water-soluble film forming polymer (keratin, chitin, chitosan or cellulose derivatives, acrylic polymers, polyvinyl pyrrolidones and vinylic copolymers, natural polymers, ethylene polymers and oxy-ethylenated silicones, etc.). The originality of this mascara consists in obtaining an increase in the water resistance of the product by introducing an aqueous solution of water-soluble substances into an anhydrous formula. The system does not contain an emulsifying agent, but nevertheless allows for a stable composition containing approximately 10% of water in a completely hydrophobic medium.
