Ethyl linolenate

Ethyl linolenate (CAS 1191-41-9) is the ethyl ester form of alpha-linolenic acid (ALA), an omega-3 fatty acid. It functions as a bioavailable lipid ingredient used across nutraceutical, cosmetic, and pharmaceutical formulations.

In nutraceutical and dietary supplement manufacturing, it serves as a concentrated omega-3 source in softgel and encapsulated formats. Precise fatty acid profiling is critical for these applications to ensure consistent product efficacy.

Cosmetic formulators incorporate it into skin-conditioning emulsions and serums. Its lipid profile supports barrier restoration and moisture retention in finished products, making it a versatile ingredient for high-end skincare lines.

Pharmaceutical developers use this compound as a reference standard or active lipid component in drug delivery systems. It is particularly effective in systems targeting omega-3 enrichment for various therapeutic applications.

It also appears in specialty food fortification applications where standardized fatty acid esters are preferred over crude oils. This preference is largely due to the superior dosing accuracy provided by the ester form.

The product is supplied as a clear to pale yellow liquid. It is available in food-grade and pharmaceutical-grade specifications, meeting rigorous quality standards such as FCC, USP, or Ph.Eur. depending on the batch.

Purity levels commonly range from 95% to 99%+ for research and formulation use. Packaging options typically include small quantities for laboratory applications and bulk formats for industrial-scale production needs.
