ABSTRACT OF THE DISCLOSURE Homogeneous storage-stable liquid stabilizer systems for polyvinyl chloride resins are provided which are substantially solvent-free and have a low viscosity and a minimum flash point of 96°C, containing, as the essential ingredients, a liquid barium carbonate-barium alkyl phenate; a cadmium salt of a branched chain aliphatic carboxylic acid having from about five to about thirteen carbon atoms, and/or of an aromatic car- borylic acid having from about seven to about eleven carbon atoms, and/or of an unsaturated aliphatic carboxylic acid having from about twelve to about twenty-two carbons; and a liquid organic tri- phosphite in an amount to form a homogeneous storage-stable liquid; the total weight percent of barium and cadmium in the stabilizer system being at least 13%; and the ratio of the weight percent of cadmium to the weight percent of barium being within the range from about 0. 5:1 to about 1. 5:1; optionally together with any one or more of a soluble zinc salt of a carboxylic acid, a soluble phenolic antioxidant, a liquid organic acid phosphate, and a soluble carboxylic acid.
