Mechanism of Action
As a silicone-based surfactant, METHOXY PEG-11 METHOXY PPG-24 DIMETHICONE is a hydrophilic copolymer derived from polydimethylsiloxane and polyethylene oxide. Its primary function is to act as an effective antifoaming agent, improving product aesthetics and application. Furthermore, its structure facilitates the creation and stabilization of mixed oil-in-water emulsions. On the skin, it forms a lightweight, breathable, non-occlusive film that contributes to moisture retention, thereby enhancing hydration without imparting a heavy or greasy sensation.
