Science
Mechanism of Action
As an emulsifier, STEARETH-8 stabilizes diverse cosmetic formulations by effectively combining immiscible oil and water components, preventing phase separation. Its surfactant properties reduce surface tension, enabling oils, dirt, and environmental pollutants to readily mix with water, facilitating their efficient removal from the skin during cleansing processes.
