ABSTRACT OF THE DISCLOSURE Stabilizer systems for vinyl halide resin compositions comprise a) a liquid, oil-soluble, epoxidized vegetable oil-compatible overbased barium salt complex that is the product obtained by contacting a reaction mixture that consists essentially of a basic barium compound, an alkylphenol, and an inert liquid organic diluent, in the amounts of at least 0.75 mole of alkylphenol per mole of barium compound and 10% to 50% by weight of the diluent, based on the weight of the reaction mixture, with carbon dioxide while the reaction mixture is maintained at a temperature of at least 180°C.; b) a polyvalent metal salt component; c) an organic phosphite component; and d) a hydrocarbon solvent in the amount of 0.1 part to 5 parts by weight of the polyvalent metal salt component, 0.1 part to 5 parts by weight of the organic phosphite component, and 0.1 part to 5 parts by weight of the hydrocarbon solvent per part by weight of the overbased barium salt complex. These stabilizer systems are compatible with epoxidized vegetable oils and form stable mixtures with such oils. - 1 -
