CHEMPOL G-12 HSA, commonly known as 12-Hydroxy Stearic Acid, is the mixed fatty acid obtained by hydrolysis of Hydrogenated Castor Oil. It is a high-melting, brittle, waxy solid at ambient temperatures and should be stored away from heat to avoid deterioration. It is insoluble in water, and its solubility in many organic solvents is also limited. It is a non-toxic, non-hazardous material and is used in the manufacturing of greases.
