Title (EN) COLOR MODIFIED MELANINS AND METHODS FOR THEIR PREPARATION AND USE
(FR) MELANINES DE COULEUR ET PROCEDES DE PREPARATION ET D'UTILISATION DE CES MELANINES
Abstract:
(EN) Color modified melanin compositions are produced by exposure of a natural or synthetic melanin starting material to a color modifying agent under controlled conditions. By treating the melanin starting materials for a preselected time period, melanin products having a desired final color may be obtained. The color modified melanin may be employed in a variety of cosmetic and other topically applied formulations. Prior to incorporation in such formulations, the color modified melanins will be cleaned to remove the color modifying agent and low molecular weight degradation products of the melanin.
(FR) Des compositions de mélanines présentant une couleur modifiée sont produites par l'exposition d'un produit de départ à base de mélanine naturelle ou synthétique à un agent de modification de couleur dans des conditions régulées. Des produits de mélanine présentant une couleur finale souhaitée peuvent être obtenus par le traitement des produits de départ à base de mélanine pendant une durée prédéterminée. La mélanine de couleur modifiée peut être utilisée dans différentes compositions cosmétiques ou à application locale. Avant d'incorporer les mélanines de couleur modifiée dans ces compositions, lesdites mélanines seront nettoyées afin d'en enlever l'agent de modification de couleur ainsi que des produits de dégradation de faible poids moléculaire de la mélanine.
