Description
Ethyl stearate (CAS 111-61-5) is a fatty acid ethyl ester produced by esterifying stearic acid with ethanol. It is commercially known under trade names including Radia 7185 and referenced as FEMA 3490 and NSC 8919. No E-code designation applies to this substance.
In personal care formulations, ethyl stearate functions as an emollient carrier, reducing skin friction and improving spreadability of active ingredients. In plastics processing, it acts as an internal plasticizer and lubricant, lowering melt viscosity and reducing die buildup during extrusion. Food-grade applications leverage its low polarity to carry flavour compounds at controlled release rates.
Ethyl stearate is supplied as a white crystalline mass and is available in cosmetic, food-grade, and technical grades. It falls under REACH registration requirements within the EU and is classified under HS code 29157010 for import and export purposes. Packaging typically includes drums and IBCs depending on volume requirements.
