Abstract
(EN)
The present invention relates to a UV-shielding complex having a structure of melanin coupled onto the surface of a particle of nontoxic oxidized inorganic material, a production method thereof, and a cosmetic composition containing the complex. In the present invention, it is preferable that the ratio of an oxidized inorganic material and melanin is 1 . (0.01 - 0.99) by weight. The UV-shielding complex produced by the present invention can be added into cosmetics as an ingredient and make the cosmetics effective in UV-shielding. According to the present invention, using a bio-compatible material makes it possible to produce a new UV shielding complex. Furthermore, the present invention enables to economically produce UV-shielding cosmetics of which color-control had formerly been difficult.

La présente invention porte sur un complexe de protection contre les rayons UV comprenant une structure de mélanine couplée sur la surface d'une particule de matière inorganique oxydée non toxique, sur son procédé de production, ainsi que sur une composition cosmétique contenant le complexe. Dans cette invention, le rapport matière inorganique oxydée sur mélanine est de préférence égal à 1:(0,01-0,99) en poids. Le complexe de protection contre les rayons UV produit selon le procédé de cette invention peut être ajouté en tant qu'ingrédient dans des produits cosmétiques et rendre lesdits produits cosmétiques efficaces contre les rayons UV. Selon la présente invention, l'utilisation d'une matière bio-compatible permet de produire un nouveau complexe de protection contre les rayons UV. Cette invention permet en outre de produire à moindre coût des produits cosmétiques de protection contre les rayons UV pour lesquels le contrôle de la couleur était jusqu'alors difficile.
