Oleoyl ethyl amide is primarily utilized in the cosmetic and personal care industry due to its emollient and moisturizing properties. It helps to improve skin hydration by forming a protective barrier that reduces water loss, making it a common ingredient in lotions, creams, and serums. Additionally, it is used in hair care products to enhance smoothness and manageability by conditioning and softening hair strands. Its ability to interact with the skin’s natural lipids also makes it suitable for formulations targeting dry or sensitive skin. Beyond cosmetics, it has potential applications in pharmaceutical formulations as a carrier for active ingredients, aiding in their absorption and delivery.
