Description
Methyl stearate (CAS 112-61-8) is a fatty acid methyl ester derived from stearic acid, commercially available under trade names including Kemester 9718, Kemester 9018, and Emery 2218. It carries no assigned E-code and is catalogued under EC 203-990-4 with HS code 29157090.
In personal care formulations, methyl stearate functions as an emollient and emulsion stabilizer by integrating into lipid layers to reduce water loss and improve texture consistency. In metalworking and industrial lubricant blends, its ester structure provides a low-friction boundary film between metal surfaces, reducing wear under moderate load conditions.
Methyl stearate is supplied as a paste-grade material and is available in REACH-compliant grades for the European market. Food-contact and cosmetic-grade material can be sourced against FCC and ISO 9001 quality frameworks. Standard packaging includes drums and IBCs, with bulk options available on request.
