Description
Triheptadecanoin (CAS 2438-40-6), also known commercially as Intarvin, Trimargarine, and Margarin C17:0, is a symmetric triglyceride composed of three heptadecanoic (margaric) acid chains esterified to a glycerol backbone. It carries no assigned E-code and is distinct from common dietary fats due to its odd-chain fatty acid composition.
In food and nutrition research, triheptadecanoin serves as an internal standard for quantifying odd-chain fatty acid intake and lipid metabolism studies, where its structural uniformity ensures reliable analytical results. In personal care formulations, it functions as an emollient and emulsifier, integrating into the lipid phase to stabilise oil-in-water systems and reduce transepidermal water loss.
Triheptadecanoin is supplied as a crystalline solid and is subject to REACH registration requirements for quantities above one tonne per year within the EU. Procurement teams should confirm purity grade and certificate of analysis specifications directly with the supplier, as analytical and cosmetic grades may differ.
