Science
Mechanism of Action
This ingredient operates by reducing the surface tension between immiscible phases, such as oil and water. As an emulsifier, it facilitates the uniform dispersion of oil droplets within an aqueous base, preventing phase separation and ensuring the stability and consistent texture of emulsion-based products like creams and lotions. Its surfactant properties additionally enable it to lower surface tension in liquids, which aids in solubilizing and lifting impurities from the skin during cleansing processes.
