Science
Mechanism of Action
This ingredient functions as a non-ionic emulsifier, creating stable oil-in-water emulsions by reducing interfacial tension between immiscible components. Additionally, it acts as an emollient, forming a protective film on the skin's surface that conditions and smooths, aiding in subtle moisture retention. Its surfactant properties also contribute to the uniform dispersion of other ingredients, including UV filters, and enhance overall formulation stability.
