ABSTRACT:
Modified colorants are made from a modifying agent, such as platelet alumina, and a colorant. The colorant may be fixed to the surface of the modifying agent, optionally with a surface treatment. The colorant may not completely coat the surface of the modifying agent, and the edge of the modifying agent may be substantially free of colorant. The modified colorants may be used in cosmetic products.
