ABSTRACT:
Melanin compositions include a melanin pigment incorporated 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 dispersed in a suitable vehicle or carrier. The melanin compositions are found to display enhanced absorbance of ultraviolet radiation when compared to melanin pigments which are not incorporated in such a polymeric particle matrix.
