Hydroxystearic Acid

Hydroxystearic Acid is a fatty acid derived from castor oil. In cosmetics, it functions as an emollient, helping to soften and smooth the skin by forming a protective layer. It also acts as a skin conditioning agent and can be used to stabilize emulsions, improving the overall texture and consistency of products.
