Ethyl linoleate

Ethyl linoleate (CAS 544-35-4) is the ethyl ester of linoleic acid, produced by esterification of the omega-6 fatty acid with ethanol. It functions as a lipid carrier, emollient, and solubilizer across pharmaceutical, cosmetic, and food applications. Linoleic acid ethyl ester is a recognized alternative name buyers use when sourcing this material for formulation work. In topical pharmaceutical and cosmetic formulations, it acts as a skin-conditioning carrier that enhances penetration.

Personal care manufacturers incorporate it into facial oils, serums, and emollient creams where a lightweight, non-greasy lipid phase is required. It is valued for its ability to deliver active ingredients into the stratum corneum effectively. In nutraceutical and food supplement production, it serves as a lipid vehicle for fat-soluble actives, supporting encapsulation and softgel fill formulations. This makes it a versatile component for modern dietary supplement manufacturing.

Flavor and fragrance applications also use it as a solvent carrier to dissolve and stabilize lipophilic aroma compounds. Its stability and compatibility with various oil-based systems make it an essential tool for industrial formulators. The material is supplied as a clear to pale yellow liquid, typically in drum or IBC quantities for industrial buyers. It is available in food-grade and cosmetic-grade specifications to meet diverse regulatory requirements.

High-purity grades exceeding 95% or 98% ester content are used in pharmaceutical and nutraceutical contexts. Certificate of analysis documentation covering purity, acid value, and peroxide value is standard for quality-sensitive procurement.
