About
A widely used polyethylene glycol ester of stearic acid with 12 moles of EO, serving as a nonionic emulsifier and opacifying agent in cosmetics.
PEG-12 Stearate is the polyethylene glycol (12 mol EO average) diester of stearic acid (octadecanoic acid). It is one of the most common emulsifiers in the cosmetic industry, used in creams, lotions, and cleansing products. The EU SCCS has assessed PEG derivatives as safe for cosmetic use at typical concentrations, provided residual ethylene oxide is below 1 ppm and 1,4-dioxane is below regulatory thresholds. It is not restricted under EU Cosmetics Regulation Annex II or III.
