PROBLEM TO BE SOLVED: To provide stabilizer mixtures. SOLUTION: The stabilizer mixtures comprises (A) a sterically hindered amine compound, and (B) two different compounds, wherein the weight ratio of the two different compounds is 1:10 to 10:1, and the two compounds are selected from the group consisting of organic salts of Zn and inorganic salts of Zn, or one compound is an organic salt of Zn or an inorganic salt of Zn, and the other compound is an organic salt of Mg or an inorganic salt of Mg, with the proviso that, (1) the stabilizer mixture is essentially free of perchloric acid, and (2) the two compounds in component (B) are different from the combination ZnO and Zn stearate and the combination ZnO and hydrotalicite. The stabilizer mixtures are useful for stabilizing organic materials, in particular, a polyolefin, against degradation induced by light, heat or oxidation. COPYRIGHT: (C)2009,JPO&INPIT
