Castor Bean Oil, Ricinus communis, also known as Palma Christi oil, is expeller pressed from the castor bean plant. Rich in fatty acids, it is a soothing, lubricating oil that is readily absorbed by the skin. It moisturizes by acting as a humectant to attract and lock moisture to the skin. Castor bean oil adds mildness and richness to soap and provides a conditioning, fluffy lather with thick, large bubbles. In hair care castor oil is commonly used in hair conditioners and in hot oil treatments for brittle, damaged hair or hair loss. Castor oil coats the hair shaft and smooths the cuticle layer, sealing in moisture and leaving the hair feeling soft and silky.
