Castor Oil is a vegetable oil obtained by pressing the seeds of the castor plant ( Ricinus Communis ). The common name " Castor Oil " probably comes from its uses as a replacement for castoreum, a parfume base made from the dried perineal glands of the beaver.

Castor oil is a colorless to very pale yellow liquid with mild or no odor or taste. Its boiling point is 313 0C ( 595 0F )and its density is 961 kg/m3. It is a triglyceride in which approximately 90 percent of fatty acid chains are ricinoleate. Oleate and llinoleates are the other significant components.

Castor oil and its derivatives are used in the manufacturing of soaps, lubricants, hydraulic and brake fluids, paints, dyes, coating, inks, cold resistant plastic, waxes and polishes, nylon, pharmaceuticals and perfumes.
