Science

Mechanism of Action

On the skin, Hydrogenated Castor Oil Stearyl Esters form an emollient, protective film that effectively reduces transepidermal water loss, thereby enhancing skin hydration and promoting a smoother, softer feel. Within cosmetic formulations, it acts as a viscosity controller, contributing to the desired thickness and stability of emulsion-based products for consistent application.
