Abstract

LA INVENCION SE REFIERE A COMPOSICIONES DE MELANINA QUE INCLUYEN UN PIGMENTO DE MELANINA INCORPORADO DENTRO DE PARTICULAS POLIMERICAS, USUALMENTE DENTRO DE UN RETICULO POROSO INTERNO DELIMITADO POR UNAQ MATRIZ DE PARTICULAS POLIMERICAS. LAS COMPOSICIONES DE MELANINA SE PUEDEN PRODUCIR POR OXIDACION IN SITU DE PRECURSORES DE MELANINA DENTRO DEL RETICULO POROSO, O POR ABSORCION DE UN PIGMENTO DE MELANINA EN UN VEHICULO O PORTADOR ADECUADO. LAS COMPOSICIONES DE MELANINA MUESTRAN UNA ABSORBANCIA DE RADIACION ULTRAVIOLETA MEJORADA Y MAYORES PROPIEDADES COSMETICAS, CUANDO SE COMPARAN CON LOS PIGMENTOS DE MELANINA NO INCORPORADOS EN UNA MATRIZ POLIMERICA COMO LA INDICADA.
