Science
Mechanism of Action
On the skin, Cholesteryl Stearate acts as an emollient, forming a thin, occlusive layer that helps to reduce transepidermal water loss, thereby softening and smoothing the skin's surface. Within cosmetic formulations, it effectively stabilizes oil-in-water emulsions by reducing interfacial tension and influences product consistency as a viscosity controlling agent.
