Stearyl Alcohol
Stearyl Alcohol (INCI: Stearyl Alcohol; CAS# 112-92-5) is a fatty alcohol derived from stearic acid, appearing as a white to light yellowish wax. It is oil-loving and functions well in oil-in-water emulsions. Unlike short-chain alcohols, it is non-drying and non-irritating. It is often combined with Cetyl Alcohol, with the resulting mixture listed as Cetearyl Alcohol on ingredient labels.
