Description
Ethylene bis(stearamide) (EBS; CAS 110-30-5) is a synthetic amide wax derived from ethylenediamine and stearic acid, commercially known under trade names including Advawax and Acrawax C. It carries no E-code designation and is classified under HS code 29242990.
In polymer processing, EBS functions as an internal and external lubricant, reducing friction between polymer chains and mould surfaces during extrusion and injection moulding. In personal care formulations, it acts as an emulsion stabiliser and hair conditioner by orienting at oil-water interfaces to improve film cohesion and reduce surface tension.
EBS is available in bead form and supplied in standard industrial packaging. It is compliant with REACH regulations and is subject to standard industrial chemical handling requirements. Procurement teams should confirm grade specifications against application requirements, particularly for cosmetic or food-contact end uses.
