About this ingredient
PEG-40 Stearate is a polyethylene glycol ester of stearic acid that functions as a non-ionic surfactant and emulsifier in cosmetic formulations. It helps stabilize oil-in-water emulsions, improve texture, and enhance product spreadability. It also acts as a gentle cleansing agent and humectant, contributing to skin conditioning benefits.
