【発明の名称】合成メラニン凝集体
Document Type and Number:
Japanese Patent JP2561714
Kind Code:
B2
Abstract:
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.
