Oleic Acid (CAS 112-80-1) is a monounsaturated fatty acid derived from vegetable oils or animal fats, supplied as a colorless to pale yellow liquid, and used in cosmetics, lubricants and surfactants as an emulsifier and emollient, in food as a carrier oil and solubilizer, and in ester and soap production. It is insoluble in water but miscible with alcohols and hydrocarbons.
