Abstract
Synthetic melanins suitable for cosmetic uses are produced through oxidative polymerization of monomeric precursors that possess aromatic rings with ionizeable side groups. Agents that enhance adherence of the melanins to skin and hair are co-polymerized with the precursors to become part of the melanin molecules. Potential new precursors and adherence-enhancing agents are screened for efficacy by subjecting them to six separate synthetic procedures, and testing the resulting melanins for color, ultraviolet absorbance charcteristics, and substantivity (adherence) to skin and hair. Melanins of different colors can be blended together in cosmetic creams and lotions to complement the natural skin, eye, and hair colors of an individual. The synthetic procedures are amendable to industrial-scale production of cosmetic melanins. The materials reduce the incidence of solar damage to the skin.
Claims
