Cadmium stearate is a salt with the formula Cd(O2CC17H35)2. Classified as a metallic soap, this a white solid is used as a lubricant and as a heat- and light-stabilizer in polyvinyl chloride. It is produced by the reaction of cadmium chloride with sodium stearate or heating stearic acid and cadmium oxide or hydroxide.[2] The use of cadmium stearate is being phased out because of its toxicity.

Safety[]

Like other cadmium compounds, cadmium stearate is toxic.[3] Cadmium stearate is also carcinogen.[4]
