Palmitodiolein is primarily used in the formulation of cosmetics and personal care products, where it serves as an emollient and skin-conditioning agent. It helps to soften and smooth the skin by forming a protective barrier that locks in moisture, making it a common ingredient in lotions, creams, and moisturizers. Additionally, it is utilized in the food industry as an emulsifier, aiding in the blending of ingredients that would otherwise separate, such as oil and water in processed foods. Its properties also make it suitable for use in pharmaceutical applications, particularly in topical formulations where it enhances the absorption of active ingredients through the skin.
