Propyl oleate is an ester derived from oleic acid and propanol. It is mainly used as an emollient, lubricant, and conditioning agent in cosmetic formulations. It is also applied as a solvent for oil-soluble compounds, a component of specialty lubricants, a plasticizer additive, and an intermediate in organic synthesis and industrial chemical production.
