Triacetin, also known as glycerol triacetate, is a clear, colorless, and odorless liquid used across the food, pharmaceutical, and cosmetics industries. The United States FDA has affirmed triacetin as generally recognized as safe (GRAS) for use in human food, and it meets all Food Chemicals Codex (FCC) specifications when produced to food-grade standards.
For kosher food manufacturers, triacetin is readily available with proper certification. Eastman Chemical Company, one of the leading producers, manufactures a dedicated Kosher Food Grade product line under rabbinical supervision in full accordance with Jewish dietary law.
What Makes Triacetin Kosher Compliant
Triacetin is produced by the acetylation of glycerol with acetic acid or acetic anhydride. The key kosher concern centers on the glycerol source.
Glycerol can be derived from animal fats (tallow), vegetable oils, or petrochemical feedstocks. Kosher-certified triacetin must use glycerol from vegetable or synthetic sources, verified through the entire supply chain.
Eastman’s kosher triacetin is manufactured under rabbinical supervision with full documentation. The product carries the CAS number 102-76-1 and meets FCC specifications for food-grade use. Manufacturers sourcing triacetin should always request the kosher certificate alongside standard quality documentation to confirm the current certification status.
Primary Food Industry Applications
Chewing gum production is one of the largest food applications for triacetin. It functions as a plasticizer in the gum base, giving the product its characteristic flexibility and chew. Without a plasticizer like triacetin, gum would be hard and brittle, making it unpleasant to use.
Triacetin also serves as a solvent and fixative for flavors and fragrances in food formulations. Its high solvency power and low volatility make it effective at dissolving flavor compounds while preventing them from evaporating prematurely. This property is valuable in baked goods, confections, and beverage applications where consistent flavor delivery matters.
Uses Beyond Food Manufacturing
In the pharmaceutical industry, triacetin works as a solvent for drugs in oral and topical formulations. It also serves as a plasticizer in capsule coatings, helping film coatings maintain flexibility and prevent cracking. Its safety profile and GRAS status make it a preferred excipient for many pharmaceutical applications.
The cosmetics industry relies on triacetin as a solvent for fragrances, essential oils, and other cosmetic ingredients. Its ability to dissolve a wide range of organic compounds while remaining stable and non-volatile makes it a practical choice for perfumes, lotions, and personal care products.
Quality and Regulatory Standards
Food-grade triacetin must comply with FCC specifications and be manufactured under GMP conditions. The product should be supplied with a certificate of analysis confirming purity, appearance, and compliance with applicable standards. Eastman’s technical data sheet lists a Setaflash Closed Cup flash point of 304 degrees Fahrenheit (151 degrees Celsius).
Beyond food use, triacetin is recognized as safe in animal feeds, as a pesticide adjuvant, and in food packaging materials. Manufacturers operating under multiple compliance programs will find that kosher-certified triacetin from established suppliers often carries halal certification as well, simplifying inventory management.
