Title (EN) DIHYDROPYRIDAZINE ANTIOXIDANT SUNSCREENS
(FR) ÉCRANS SOLAIRES ANTIOXYDANTS À BASE DE DIHYDROPYRIDAZINE
Abstract:
(EN) Herein polymers and particles which comprise a plurality of dihydropyridazine or hydropyridazine functional groups are described. Methods for their formation and specific monomers which may be used in their formation are also described. The polymers and particles are UV absorbing, hydrogen-donor antioxidant materials which signal a depletion of antioxidant ability by a decrease in visible fluorescence. These polymers and particles may be used as UV protectants for a variety of materials and substrates and may even be used in a topically applied formulation for human skin.
(FR) L'invention concerne des polymères et des particules qui comprennent une pluralité de groupes fonctionnels de dihydropyridazine ou d'hydropyridazine. L'invention concerne également des procédés pour leur formation et des monomères spécifiques qui peuvent être utilisés dans leur formation. Les polymères et les particules sont des matériaux antioxydants donneurs d'hydrogène absorbant des UV, qui signalent un appauvrissement de la capacité antioxydante par une diminution de la fluorescence visible. Les polymères et les particules selon l'invention peuvent être utilisés en tant que protecteurs des UV pour une variété de matériaux et de substrats et peuvent même être utilisés dans une formulation appliquée par voie topique sur la peau chez les humains.
