• Application: Triacetin serves a versatile role across multiple industries primarily due to its unique chemical properties. It is a triglyceride formed by the acetylation of glycerol's three hydroxy groups, resulting in a colorless, viscous liquid with a slightly fatty odor. Known chemically as glyceryl triacetate, triacetin is predominantly employed as a hydrophilic plasticizer in the coating of capsules, tablets, beads, and granules, enhancing the flexibility and durability of these materials. Moreover, it finds application in cosmetics, perfumery, and the food industry as an effective solvent and fixative for perfumes and flavors. Triacetin also exhibits fungistatic properties because it releases acetic acid upon hydrolysis by skin esterases, which makes it useful in treating minor dermatophyte infections. This release of acetic acid, while beneficial, is self-limiting due to the inhibition of these enzymes at lower pH levels. Through its multifaceted functionality, triacetin effectively contributes to various formulations, offering enhanced performance and stability.
