Description

Ethyl stearate (CAS 111-61-5 ), also recognized by its FEMA 3490 designation in flavoring applications, is a fatty acid ester derived from stearic acid used as a plasticizer and lubricant. It serves as an emulsifier and carrier across food, cosmetic, and industrial sectors. Its low polarity and ester structure make it effective for solubilizing lipophilic actives and modifying surface properties. In food and flavoring, it functions as a carrier and fixative for flavor compounds, recognized under FEMA 3490 for use in approved applications. Personal care formulators incorporate it into creams and lotions. It is used in hair products where it softens texture and aids dispersion of active ingredients. Industrial lubricant manufacturers use it as a base fluid or additive in metalworking fluids and release agents. Its film-forming character reduces surface friction in various industrial settings. In plastics processing, it acts as an internal or external plasticizer and processing aid to improve flow and reduce brittleness. Ethyl stearate is supplied as a white to off-white waxy solid or as a liquid above its melting point. It is available in food-grade and technical-grade specifications for diverse manufacturing needs. Food-grade material conforms to relevant purity standards for flavoring use. Bulk supply is typically offered in drums or IBCs, with smaller packaging available for specialty or laboratory applications. Contact us for supply of Ethyl stearate Request Quote
