CA 2082952

Color modified melanin compositions are produced by exposure of a natural or synthetic melanin starting material to a color modifying agent under controlled conditions. By treating the melanin starting materials for a preselected time period, melanin products having a desired final color may be obtained. The color modified melanin may be employed in a variety of cosmetic and other topically applied formulations. Prior to incorporation in such formulations, the color modified melanins will be cleaned to remove the color modifying agent and low molecular weight degradation products of the melanin.
