Science
Mechanism of Action
This ingredient functions as a surfactant by reducing surface tension within skincare formulations. As a cleansing agent, it aids in lowering the surface tension of the stratum corneum, promoting the effective removal of dirt and impurities. Its emulsifying action stabilizes oil-in-water emulsions by reducing interfacial tension between immiscible phases, ensuring a homogeneous product. Furthermore, it acts as a solubilizer, facilitating the uniform dispersion and transport of oil-soluble cosmetic components into aqueous solutions. The polyglycerol base itself contributes emollient and moisturizing benefits, helping to form a protective film on the skin.
