Castor bean (Ricinus communis L.) has high oil content in seeds (46–55%) and is an important alternative in the production of biodiesel. Its oil is the only commercial source of ricinoleic acid (12-hydroxy oleic acid). This fatty acid gives the highest viscosity and stability among vegetable oils currently used in the composition of paints, varnishes, lubricants, plastics, and, mainly, cosmetics (Ogunniyi, 2006).
