  • Applications

    11-Eicosenamide, (11Z)- (CAS 10436-08-5) is a long-chain fatty amide commonly used as a slip/anti-block additive and processing aid in polymer and plastics applications, helping to reduce friction and improve surface finish in polyolefins and other resins; it is also employed as a lubricant or formulation aid in specialty lubricants and metalworking fluids, contributing to smoother processing and reduced wear; in cosmetics and personal care it can function as a waxy emollient or texture-enhancing ingredient; in coatings, inks and cleaning formulations it may act as a surfactant-like additive or slip agent to improve flow and leveling; it may also serve as an intermediate for the synthesis of specialty fatty amide derivatives, subject to local regulations and formulation limits.
