Triacetin (glyceryl triacetate) is a colorless, odorless, and hygroscopic organic ester widely used as a plasticizer, solvent, and humectant in pharmaceuticals, food, cosmetics, and ink formulations. It also serves as a cellulose plasticizer in cigarette filter manufacturing, an inert plasticizer in solid rocket propellant binders, and a fixative in perfumery. It enhances flexibility, solubility, and moisture retention in formulations while meeting strict regulatory standards. Triacetin meets Ph. Eur., BP, and USP monographs, with a CAS number of 102-76-1, molecular formula C9H14O6, and molecular weight of 218.20. It is stable at ambient storage conditions and carries no signal word for hazard classification. Molekula supplies Triacetin from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
