Description
Ethyl linolenate (CAS 1191-41-9, EC 214-734-6) is the ethyl ester of alpha-linolenic acid, an omega-3 fatty acid derivative. Also known as ethyl alpha-linolenate or linolenic acid ethyl ester, it carries no assigned E-code and is classified under HS code 29161900 within the oils, fats, and waxes category.
In personal care formulations, ethyl linolenate functions as a skin-conditioning humectant, reinforcing the lipid barrier by integrating into intercellular structures to reduce transepidermal water loss. In food and pharmaceutical applications, its polyunsaturated structure enables antioxidant activity, where it acts as a sacrificial substrate to slow oxidative degradation of sensitive co-ingredients.
Ethyl linolenate is sourced as a clear, colorless oil and is available in food-grade and cosmetic-grade specifications. Suppliers operating under REACH compliance should confirm registration status for EU market supply. Packaging typically ranges from small laboratory quantities to drum volumes for industrial procurement.
