Triheptanoin

Triheptanoin (CAS 620-67-7), also known as glycerol triheptanoate, is a synthetic triglyceride composed of three heptanoic acid chains esterified to a glycerol backbone. It functions as an emollient, skin-conditioning agent, and carrier in formulations where controlled lipid delivery and oxidative stability are priorities.

In cosmetic and personal care formulations, it provides a lightweight, non-greasy skin feel in serums, sunscreens, and color cosmetics. It also acts as a solvent for UV filters and oil-soluble actives, offering a high-performance alternative to conventional plant-derived oils.

Pharmaceutical manufacturers use it as a carrier oil in topical drug delivery systems and as a medium-chain triglyceride alternative in oral and parenteral nutrition research applications. Its unique structure allows for precise metabolic targeting in clinical settings.

In food and nutraceutical contexts, it serves as a structured lipid for metabolic studies and specialized clinical nutrition products. Its oxidative stability relative to unsaturated oils makes it a preferred carrier in sensitive formulations with long shelf-life requirements.

The material is supplied as a clear, colorless to pale yellow liquid. It is available in cosmetic-grade and pharmaceutical-grade specifications, with pharmaceutical supply typically aligned to GMP manufacturing standards.

Packaging ranges from small quantities for R&D use to bulk drums for commercial production. This versatility ensures that both laboratory-scale development and large-scale industrial manufacturing needs are met with consistent quality and reliable supply chains.
