Triheptadecanoin

Triheptadecanoin (CAS 2438-40-6), also known as glycerol triheptadecanoate, is a synthetic odd-chain triglyceride used as a reference standard and functional lipid ingredient across food and cosmetic applications.

Its defined, uniform fatty acid composition makes it a reliable tool for analytical calibration and a controlled-purity emollient base where consistency is critical for high-end manufacturing processes.

In food and nutrition research, it is used as an internal standard for quantifying triglyceride content in lipid profiling and fatty acid analysis by GC and HPLC. This ensures precision in complex testing.

Cosmetic formulators incorporate it into emollient systems where a structurally defined triglyceride is required to benchmark performance or support stability testing. It provides a consistent baseline for new products.

As a functional lipid, it contributes moisturizing and skin-conditioning properties in creams and lotions, acting as an emollient carrier within oil phases. It integrates seamlessly into various topical formulations.

Its odd-chain structure distinguishes it from naturally occurring triglycerides, making it traceable in biological and formulation matrices. This unique chemical signature is highly valued in specialized research.

The material is supplied as a white to off-white solid or waxy powder. It is available primarily in high-purity analytical and research grades, with purity specifications typically at 99% or above for accuracy.

Food-grade and cosmetic-grade material is also available for formulators requiring larger quantities beyond laboratory scale. These batches meet rigorous industry requirements for safety and performance.
