Science & Benefits

PEG-100 Stearate is a highly effective, non-ionic emulsifier created by the ethoxylation of stearic acid. It is prized for creating 'thin' emulsions (lotions/milks) that spread easily. It is 100% acne-safe with a negligible comedogenic rating of 1. It is a 'bulletproof' choice for oil-free acne moisturizers because it facilitates a weightless finish that doesn't trap heat or bacteria in the follicle.
