The castor plant (Ricinus communis) is a coarse herb of the spurge family Euphorbiaceae. When processed, the seed syn. castor bean yields half its weight in a triglyceride oil that is, uniquely, up to 85% ricinoleic acid. The oil is used as an ingredient or precursor in the manufacture of paints, varnishes, resins, synthetic fibres, lubricants, polishes, cosmetics, and many other materials.
