COMPOSITIONS COMPRISING PIGMENT PARTICLES ENTRAPPED IN COLLAPSED POLYMERIC MICROSPHERES, AND METHODS OF MAKING THE SAME

摘要

Topical compositions containing pigment particles entrapped in microspheres are provided. Each of the microspheres contains a collapsed polymeric shell that has entrapped therein one or more pigment particles. The microsphere-entrapped pigment particles are characterized by enhanced color intensity, improved stability, and better dispersibility, which can readily be used either alone or in combination with other skin active ingredients to form better colored cosmetics.
