Science

Mechanism of Action

This ingredient reduces interfacial tension, enabling the stable formation of oil-in-water mixtures and maintaining product integrity. As a surfactant, it facilitates the cleansing process by aiding in the removal of impurities from skin and hair. Furthermore, it functions as a solvent to dissolve various formulation components and acts as an opacifier to impart a cloudy appearance, thereby decreasing product transparency. Its inherent emollient and skin conditioning properties also support skin comfort.
