About this ingredient

PEG-100 Stearate is a polyethylene glycol ester of stearic acid that functions as a non-ionic surfactant and emulsifier in cosmetic formulations. It stabilizes oil-in-water emulsions, improves texture, and enhances solubilization of hydrophobic ingredients. Commonly used in creams, lotions, and sunscreens to create smooth, spreadable formulas with improved sensory appeal.
