Castor Oil, also known as castor wax, is a hardened vegetable wax produced from pure castor oil through the chemical process of hydrogenation. When hydrogen is introduced to pure castor oil in the presence of a nickel catalyst, the resulting product becomes waxy, highly viscous, and more saturated.
Castor Oil is an ingredient prevalently found in many cosmetics, varnishes, and polishes. You most likely use it on a daily basis. Unlike pure castor oil, which is said to have a slightly offensive smell, it is completely odorless. Hydrogenated castor oil is also insoluble in water.
The purpose of the hydrogenation process is to improve castor oil's melting point, texture, odor, and shelf-life.
Once hydrogenated, the resulting castor oil product is comprised of hard, brittle flakes. Hydrogenated castor oil is considered an organic ingredient, as well as a vegan one, as it is vegetable-derived.
One application of hydrogenated castor oil is to improve certain cosmetic products. You can add the flakes to cosmetic formulations until thoroughly melted. In this capacity, hydrogenated castor oil acts as an emollient and a thickener; increasing the viscosity of creams, ointments, and lotions when their composition is too runny.
