Castor oil is a versatile oil that has long been used medicinally, in personal care products, and in industrial applications. Made from the pressed beans of the castor plant, castor oil is typically clear or pale yellow, and unlike the unprocessed castor beans, castor oil is safe for human consumption.
Castor oil is high in ricinoleic acid, which makes it useful as an additive in animal feed, as a grain preservative, and as an ingredient in coatings and lubricants for industrial use. In personal care products, castor oil is beloved for its emollient and humectant properties when added to formulas for skin or hair.
