Composition and process for producing pigmentation in hair or skin |
摘要 |
A composition and process for producing pigmentation in hair and skin is disclosed which employs non-mutagenic compounds to duplicate naturally occurring biosynthetic colors. The composition for imparting golden coloration comprises as active ingredients a solution of a tyrosine derivative having a side chain with a substituted amine group in admixture with certain compounds having a reactive nitrogen moiety, and is topically applied in the presence of an oxidant. The composition for imparting a dark coloration comprises as active ingredients s solution of tyrosine derivative having a side chain free for indole formation in admixture with certain compounds having a reactive nitrogen moiety, and is topically applied in the presence of an oxidant. Mixtures of the two compositions may be applied to impart proportionate intermediate colors.
