Octadecyl acetate is widely used as a lubricant additive in industrial applications, enhancing the performance and longevity of machinery by reducing friction and wear. It is also employed in the formulation of personal care products, such as creams and lotions, where it acts as an emollient to soften and smooth the skin. In the textile industry, it serves as a softening agent for fabrics, improving their texture and feel. Additionally, it is utilized in the production of coatings and paints, where it helps in improving spreadability and finish quality. Its hydrophobic properties make it suitable for use in water-repellent treatments for various materials.
