Hydrogenated castor oil, commonly referred to as HCO or castor wax, is a hard, white, opaque vegetable wax that is derived from the hydrogenation of virgin castor oil. This process involves heating the pure liquid castor oil obtained from castor beans under extreme pressure with a nickel catalyst, resulting in the creation of saturated molecules with a higher melting point. As a result, the oil transforms into a solid form at room temperature. This waxy compound exhibits a fine, almost white or pale yellow appearance and is sold in flakes or powder form. Its exceptional resistance to moisture makes it versatile for various applications. It is widely used in coatings, greases, cosmetics, polishes, and other products that require durability and stability under different conditions. In the pharmaceutical industry, hydrogenated castor oil is employed in both oral and topical formulations, providing stiffness to creams and emulsions, while also serving as a component for sustained-release tablet and capsule preparations. Its lubrication properties are harnessed in processes such as die wall lubrication in tablet presses and food processing. Additionally, hydrogenated castor oil finds uses as a slip additive in inks, paints, and plastics, a dispersing agent in color master batches, and as an ingredient in personal care products like lipsticks and deodorant sticks.
