Hydrogenated castor oil is a fine, almost white to pale yellow powder, practically insoluble in water, m.p. 83–88°C. It contains principally 12-hydroxystearic acid.

Properties

Hydrogenated castor oil is a hard, wax-like substance extracted from castor oil beans. There is also a petroleum-based formula of Hydrogenated Caster Oil known as PEG-40. The Hydrogenated Castor Oil chemical formula of this material is C57H110O9(CH2CH2O)n. Hydrogenation refers to a chemical process where an unsaturated compound is combined with hydrogen to produce saturation. In the case of HCO, this increases the oil’s stability and raises its melting point, transforming it into a solid at room temperature.

Applications
