What it is
Hydrogenated Castor Oil Hydroxystearate is derived from castor oil that has been hydrogenated and esterified with hydroxystearic acid. It functions as a rich emollient and can help structure and thicken oil-containing formulas, contributing to a smooth, cushioned skin feel. It is used in sunscreens and creams to condition the skin and adjust texture.
Safety & warnings
