General description

Triacetin is a triester of glycerin and acetic acid that occurs naturally in papaya. It is mainly used as a synthetic flavoring agent in ice-creams, nonalcoholic beverages and baked goods.

Application


  • Glycerol Triacetate-Based Flame Retardant High-Temperature Electrolyte for the Lithium-Ion Battery.: This paper highlights the use of Triacetin as a flame retardant and high-temperature stable electrolyte component in lithium-ion batteries, enhancing safety and efficiency (Wu X et al., 2024).

  • Understanding the Interaction of Thermal, Rheological, and Mechanical Parameters Critical for the Processability of Polyvinyl Alcohol-Based Systems during Hot Melt Extrusion.: Triacetin is investigated for its effects on the processability of polyvinyl alcohol in hot melt extrusion, focusing on its role as a plasticizer to modify thermal and mechanical properties (Hess F et al., 2024).
