Castor oil is a vegetable oil pressed from castor beans. The name probably comes from its use as a replacement for castoreum. Castor oil is a colorless to very pale-yellow liquid with a distinct taste and odor. Its boiling point is 313 °C (595 °F) and its density is 961 kg/m3. It is a triglyceride in which approximately 90 percent of fatty acid chains are ricinolates. Oleate and linoleates are the other significant components. Castor oil and its derivatives are used in the manufacturing of soaps, lubricants, hydraulic and brake fluids, paints, dyes, coatings, inks, cold resistant plastics, waxes and polishes, nylon, pharmaceuticals and perfumes.

Castor oil is well known as a source of ricin oleic acid, a monounsaturated, 18-carbon fatty acid. Among fatty acids, ricin oleic acid is unusual in that it has a hydroxyl functional group on the 12th carbon. This functional group causes ricin oleic acid (and castor oil) to be more polar than most fats. The chemical reactivity of the alcohol group also allows chemical derivatization that is not possible with most other seed oils. Because of its ricin oleic acid content, castor oil is a valuable chemical in feedstocks, commanding a higher price than other seed oils.
