詳細
Castor oil is a vegetable oil obtained by pressing the seeds of the castor oil plant (Ricinus communis). The common name "castor oil", from which the plant gets its name, probably comes from its use as a replacement for castoreum, a perfume base made from the dried perineal glands of the beaver (castor in Latin).
Triglycerides (triple esters of glycerol and fatty acids) forming it accounts for about 90% of its fatty acids. The majority of global production comes from India.
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 listed as a food additive in the Codex Alimentais (E1503); it also serves to the preparation of an emulsifier, the E476 or PGPR (polyglycerol polyricinoleate), used in particular in the chocolate industry to thin the chocolate during its production and allow manufacturers allowed to do to replace the expensive cocoa butter.
