Publication number: 20110089384Abstract: The present invention relates to highly compatible hydroxyphenyltriazine UV-absorbers and to their use in organic polymers, especially for protecting the contents of transparent plastic packages such as pharmaceuticals, cosmetics, personal care products, shampoos and the like, and especially foodstuffs such as beverages, fresh vegetables or meat, from the deleterious effects of ultraviolet radiation. Especially advantageous is the combined use of a UV absorber and an oxygen scavenger. It has been found that certain highly compatible tris-aryl-s-triazines are especially effective towards this end when incorporated in the containers or films in which such materials are stored.Type: ApplicationFiled: October 28, 2010Publication date: April 21, 2011Inventors: DARIO LAZZARI, Manuele Vitali, Michela Bonora, Graziano Zagnoni, Marie-Raphael Morvillier
