Used as an emollient in cosmetics and personal care products to soften and smooth the skin. Commonly found in lotions, creams, and hair conditioners due to its moisturizing properties. In pharmaceuticals, it serves as a carrier oil and solvent for drug delivery, especially in injectable formulations for water-insoluble active ingredients such as certain hormones or steroids. Its non-volatile nature and good skin penetration enhance its utility in these applications. Also used in the synthesis of other oleic acid derivatives and as a lubricant in industrial applications.
