  • Applications

    Ethylene-N-palmitamide-N'-stearamide (CAS 5136-44-7) is a mixed fatty-amide diamide derived from palmitic and stearic acids linked to ethylenediamine, presenting a high-melting, wax-like material used as a slip agent and processing aid as well as a thickener/texture enhancer in plastics formulations and coatings. In polymer processing and extrusion, it serves as a lubricant/anti-block agent and processing aid to reduce friction, improve feedability, and aid mold release for polyolefins and related resins. In coatings and inks, it can act as a rheology modifier and surface lubricant to improve flow and surface feel during application. In cosmetics and personal care, it is employed as a thickener and texture modifier, enhancing viscosity and tactile properties in creams and lotions. It may also be used as an additive in adhesives and in wax-based formulations to improve slip and structuring. Its use is subject to local regulations and formulation limits.
