Description
Docosahexaenoic acid, commonly abbreviated as DHA, is a long-chain omega-3 fatty acid with CAS 6217-54-5, also known under the trade names Cervonic acid and Cervonate. It carries no assigned E-code and is identified by the shorthand notation 22:6(n-3), reflecting its 22-carbon chain with six double bonds.
In food and nutrition manufacturing, DHA is incorporated into infant formula and functional foods where it supports lipid-phase stability and contributes to flavour profile at controlled inclusion levels. In personal care formulations, it functions as an emollient and skin conditioner by integrating into the lipid barrier, reducing transepidermal water loss and modifying surface wetting behaviour.
DHA is available in pharmaceutical and food-grade forms, with compliance referenced against FCC and Ph.Eur. monographs depending on application. The substance falls under REACH registration obligations within the EU and is classified under HS code 29161900. Packaging is typically supplied in drums or intermediate bulk containers under inert atmosphere to limit oxidation.
