Oleyl Alcohol is a long-chain (C18) unsaturated fatty alcohol derived from oleic acid. Its single double bond keeps it liquid at room temperature, unlike many saturated fatty alcohols, which is part of why it performs well as an emollient and lubricant base.
This fatty alcohol is manufactured into cosmetic and personal-care formulations as an emollient and skin-penetration enhancer, and used in industrial applications as a lubricant additive and defoamer component.
