Description
Octadecyl stearate (CAS 2778-96-3) is a waxy ester formed by the reaction of stearyl alcohol with stearic acid. It is sold under trade names including Loxiol G 30, Cosmol 1000, Cyclochem SS, EMALEX CC-18, and FE 78-18. It carries no assigned E-code and is classified under HS code 29157090.
In cosmetic formulations, it functions as an emollient and consistency agent, reducing interfacial tension between oil and water phases while contributing a non-greasy skin feel. In plastics processing, it acts as an internal and external lubricant, lowering melt viscosity and reducing friction between polymer chains and metal surfaces during extrusion or calendering.
Octadecyl stearate is supplied as a powder or platelet grade and is subject to REACH registration requirements within the EU. Procurement teams should confirm supplier documentation for compliance with relevant cosmetic and industrial safety standards. Standard packaging formats include fibre drums and multi-wall paper sacks.
