Science
Mechanism of Action
This ingredient functions by stabilizing oil-in-water emulsions, ensuring homogeneous and stable product formulations such as creams and lotions. As a surfactant, it lowers surface tension, aiding in the effective removal of impurities from the skin. Its solubilizing properties enable the uniform dispersion of oils and fragrances within aqueous solutions. Additionally, it helps to maintain the skin's natural moisture barrier, contributing to hydration and defense against dryness.
