  • Publication number: 20110089384
    Abstract: 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.

  • Publication number: 20100048773
    Abstract: The present invention relates to agricultural articles which keep their properties during the use and degrade later on, until total disintegration and disappearance of the plastic. The invention further relates to a method for controlling the weathering resistance and the degradation of agricultural articles. The desired effect is obtained with specific combinations of degradant metal salts and stabilizers. The agricultural article of the present invention comprises an organic polymer, an organic salt of Fe, Ce, Co, Mn, Cu or Vd and one or more sterically hindered amine compounds.
