Triacetin (CAS 102-76-1), also known as glycerol triacetate or 1,2,3-triacetoxypropane, is a colorless, odorless, viscous liquid with the molecular formula C₉H₁₄O₆. It is the triester of glycerol and acetic acid, widely recognized as a versatile, biodegradable, and non-toxic compound. Its excellent solvency, low volatility, and high stability make it an essential additive across industries.
Key Applications and Uses of Triacetin

Frequently Asked Questions (FAQs)
What is Triacetin used for?
Triacetin is primarily used as a plasticizer, solvent, and humectant in pharmaceuticals, food, cosmetics, tobacco, and industrial applications. It enhances flexibility in coatings, maintains moisture in foods, and acts as a carrier for flavors and fragrances.
Is Triacetin safe for food and pharmaceutical use?
Yes, Triacetin is FDA-approved as GRAS and meets USP/EP standards. It has low toxicity and is widely used in edible products and medications without adverse effects when used as directed.
What is the difference between Triacetin and other acetates?
Triacetin is the tri-ester of glycerol and acetic acid, offering higher solvency and plasticizing efficiency compared to mono- or di-acetates. It provides better compatibility with hydrophilic materials.
How should Triacetin be stored?
Store in a cool, dry place in sealed containers to avoid hydrolysis. Ideal temperature range is 15-30°C. Avoid exposure to moisture, heat, or incompatible substances like strong oxidizers.
Is Triacetin environmentally friendly?
Triacetin is biodegradable and derived from renewable sources like glycerol. It has a low environmental persistence and is considered a greener alternative to many synthetic solvents.
