Hydrogenated Castor Oil (CAS 8001-78-3), also known as castor wax, is a fully hydrogenated derivative of natural castor oil. Through catalytic hydrogenation, the ricinoleic acid chains are converted to saturated fatty acids, resulting in a hard, high-melting-point, white to off-white wax. It is prized for its excellent stability, emollient properties, and ability to form rigid, glossy films. This non-greasy, odorless, and inert wax is a versatile ingredient widely used in cosmetics, industrial lubricants, and coatings.
