Hydrogenated Castor Oil (HCO), also called Castor Wax, is a hard, brittle, high melting solid which is tasteless and odorless. Chemically it is the triglyceride mainly of 12-Hydroxy Stearic Acid. It is insoluble in water and solubility in many organic solvents is also very limited.
HCO is available as flakes or powder which melts to a clear transparent liquid. It is a non-toxic, non-hazardous material.
HCO is used in pharmaceutical applications and manufacture of greases and lubricants. It is used in a range of cosmetics & toiletries.
