Title
(EN) COMPOSITE MATERIAL COMPRISING UV FILTERS AND PLASMONIC PARTICLES, AND USE AS SUN SCREEN
(FR) MATERIAU COMPOSITE COMPRENANT DES FILTRES UV ET DES PARTICULES PLASMONIQUES ET UTILISATION EN PROTECTION SOLAIRE.
Abstract
(EN)
The present application relates to a composite material that screens out ultraviolet radiation and comprises at least one plasmonic particle formed from at least one metal and at least one organic agent that screens out ultraviolet radiation, said screening agent being located inside the plasmonic particle or outside the plasmonic particle, at a sufficiently short distance from the plasmonic particle so that the absorption of the ultraviolet radiation over at least one portion of the spectrum of the screening agent is increased. The present application also relates to a method for the cosmetic treatment of skin or hair in order to protect the same against the effects of UV rays, said method involving applying an effective amount of such a composite material to the skin or hair, and to a method for photostabilizing and/or for increasing the absorption of a photoprotective agent by means of at least one plasmonic particle.
(FR)
La présente demande concerne un matériau composite filtrant le rayonnement ultra-violet comprenant au moins une particule plasmonique formée d' au moins un métal et au moins un agent organique filtrant le rayonnement ultra-violet, ledit agent filtrant étant situé à l'intérieur de la particule plasmonique ou à l' extérieur de la particule plasmonique à distance suffisamment faible de la particule plasmonique, de sorte que l 'absorption du rayonnement ultra-violet sur au moins une partie du spectre de l' agent filtrant soit augmentée. La présente demande concerne aussi un procédé de traitement cosmétique de la peau ou des cheveux destiné à les protéger contre les effets des rayons UV consistant à appliquer sur ceux-ci une quantité efficace d'un tel matériau composite, et un procédé de photostabilisation et/ou d' augmentation de l' absorption d'un agent photoprotecteur avec au moins une particule plasmonique.
