The castor oil plant (Ricinus communis) most likely originates in East Africa; it is grown in Brazil, China, and India. Its oil is extracted from seeds that contain 40 to 60% oil.
Castor oil is primarily made up of ricinoleic acid. This mono-unsaturated fatty acid has an unusual “slowing” texture and viscosity.
Castor oil’s fluidity offers a a high lubricating power. It is an excellent agent wetting and scattering pigments in make-up products.
It is used by the pharmaceutical industry (excipient, laxative) as well as in cosmetic (nail polishes, lipsticks, creams and lotions, sprays and shampoo).
