  • Applications

    2,4-Hexadecadienamide, N-(2-methylpropyl)-, (E,E)- (CAS 54794-69-3) is a specialty chemical used in industrial manufacturing as an intermediate for the synthesis of functional polymers and as a waxy lubricant/additive (slip agent) in plastics, coatings and adhesives; in perfumery and cosmetics it is often evaluated as a fragrance fixative or carrier to improve scent retention and formulation stability; it can function as a lipid-like conditioning component in cosmetics and personal care formulations; its applications are typically described as an industrial intermediate, plasticizer/processing aid, or conditioning additive, with use governed by local regulations and formulation limits.
