Stearanilide is primarily used as a lubricant and slip agent in various industrial applications. It is commonly incorporated into polymer processing, particularly in the production of plastics, to enhance mold release and reduce friction during manufacturing. This chemical is also utilized in the formulation of coatings and inks, where it improves surface smoothness and prevents sticking. Additionally, stearanilide finds application in the cosmetics industry, where it acts as an emollient and thickening agent in skincare products, contributing to a smooth texture and improved spreadability. Its ability to provide lubrication and stability makes it a valuable additive in multiple manufacturing and personal care processes.
