Calcium Stearate CAS#1592-23-0

Basic Information

Calcium Stearate
calcium octadecanoate
C17H35COO
(C₁₇H₃₅COO)₂Ca

Calcium stearate is a fine white crystalline metal soap with high heat resistance and very low water solubility. It dissolves more readily in hot aromatic solvents, reacts with strong acids to form stearic acid and calcium salts, and resists lipolytic microorganisms. It is used as a processing and formulation additive where a stable calcium stearate powder is required. Its thermal behavior, hydrophobicity and acid reactivity support plastics, coatings and other industrial compounding systems described for metal stearates.
