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.
本发明涉及高相容性羟苯基三嗪
紫外线吸收剂及其在有机聚合物中的应用,特别是用于保护透明塑料包装中的内容物,如药品、化妆品、个人护理产品、洗发
水等,尤其是食品,如饮料、新鲜蔬菜或肉类,免受紫外线辐射的有害影响。特别有利的是
紫外线吸收剂和氧清除剂的联合使用。研究发现,某些相容性很强的三芳基-s-三嗪类化合物在用于储存此类材料的容器或薄膜中使用时,对达到这一目的特别有效。
