INCI: PEG-120 Methyl Glucose Dioleate
PEG-120 Methyl Glucose Dioleate is a synthetic emulsifier derived from glucose (a sugar) and oleic acid (a fatty acid from vegetable oils), modified with a long polyethylene glycol (PEG-120) chain. It works by reducing surface tension between oil and water phases in a formulation, keeping them blended into a stable, uniform product. It is most commonly found in cleansing gels, shampoos, and body washes where it also contributes a mild, skin-friendly lather.
