Mechanism of Action
As a derivative of PEG/PPG compounds, this ingredient functions primarily as an emulsifier, stabilizing mixtures of immiscible liquids like oil and water in cosmetic formulations. It additionally acts as a cleansing agent, helping to effectively remove impurities from the skin. Beyond these foundational roles, it serves as a skin-conditioning agent, contributing to a smooth and supple skin feel, and can also function as a humectant to aid in moisture retention within the skin.
