SYNTHETIC MELANIN AGGREGATES BACKGROUND OF THE INVENTION Abstract of the Disclosure Melanin compositions include a melanin pigment incorporated within polymeric particles, usually within an internal pore network defined by a polymeric particle matrix. The melanin compositions may be produced by in situ oxidation of melanin precursors within the pore network, or by absorption of a melanin pigment in a suitable vehicle or carrier. The melanin compositions are found to display enhanced absorbance of ultraviolet radiation and better cosmetic attributes when compared to melanin pigments which are not incorporated in such a polymeric particle matrix.
