Tricaprylin

CAS: 538-23-8

Overview

Tricaprylin (CAS 538-23-8 ), also known as tricaprylyl glycerol, is a triglyceride ester of glycerol and caprylic acid used as a carrier, emollient, and solubilizer across food, pharmaceutical, and personal care manufacturing.

It delivers stable, lipid-based dispersion for active ingredients that require an inert, non-aqueous medium. In pharmaceutical formulations, it functions as a lipophilic carrier for poorly water-soluble APIs in soft gel capsules.

This material is essential for oral lipid-based drug delivery systems and injectable preparations. Food manufacturers use it as a fat replacer and carrier for fat-soluble vitamins, flavors, and nutraceutical actives in encapsulated products.

Personal care formulators incorporate it into skin creams, serums, and sunscreens where a lightweight, non-greasy emollient is required. It also serves as a reference standard and excipient in lipid nanoparticle research.

The product is supplied as a clear, colorless to pale yellow liquid. Pharmaceutical and food-grade material is available to USP , FCC , and Ph. Eur. specifications, supporting regulatory compliance across multiple markets.

Technical-grade material is also available for industrial and research applications. This versatile triglyceride ensures high stability and performance in diverse chemical formulations and high-purity manufacturing environments.
