Application

Triacetin, USP serves as a versatile chemical compound with a range of applications, primarily due to its properties as a triglyceride derived from glycerol and acetic acid. This colorless, viscous liquid is utilized extensively as a hydrophilic plasticizer in the coating of capsules, tablets, beads, and granules, enhancing their formulation at concentrations typically between 10-35% w/w. In perfumery, triacetin acts as a fixative and solvent, enhancing the stability and longevity of fragrances and flavors. Its fungistatic properties, resulting from the release of acetic acid, lend it effectiveness in the topical treatment of minor dermatophyte infections. Additionally, triacetin's ability to dissolve in water and blend seamlessly with alcohol and most organic solvents makes it a valuable component in cosmetic, photographic, and food industries, as well as in the dyeing process where it functions as a solvent for basic dyes.
