Hydrogenated Castor Seed Oil
Hydrogenated Castor Seed Oil is a thick, conditioning emollient derived from castor beans. It is widely used in UK lipsticks, balms, mascaras and creams to provide smooth texture, moisture and long-wearing properties. Gentle and non-greasy once applied, it is a popular plant-based alternative to petroleum-derived ingredients.
How it works in skincare
In cosmetics and skincare, Hydrogenated Castor Seed Oil functions as an emollient, thickener and film-former. The hydrogenation process converts the liquid castor oil into a semi-solid wax-like material that helps stabilise emulsions, prevents lipstick sweating, improves product adhesion to lips and lashes, and creates a protective barrier that locks in moisture without feeling heavy.
