Triacetin[edit]
Triacetin, also known as glycerol triacetate, is a chemical compound that belongs to the class of compounds known as triesters. It is formed by the esterification of glycerol with three acetic acid molecules. Triacetin is a colorless, viscous liquid with a mild odor and is used in various industrial applications.
Chemical Properties[edit]
Triacetin has the chemical formula C9H14O6 and a molecular weight of 218.21 g/mol. It is soluble in water, alcohol, and ether. The compound has a boiling point of approximately 258 °C and a melting point of -78 °C.
Uses[edit]
Triacetin is used in a variety of applications due to its plasticizing, solvent, and fixative properties. Some of the primary uses include:
- As a plasticizer in the production of plastics and resins.
- As a solvent for cellulose acetate in the manufacture of cigarette filters.
- As a fixative in perfumery to stabilize fragrances.
- In the food industry as a food additive (E1518) to improve the texture and stability of baked goods and confectionery.
Biological Role[edit]
Triacetin is metabolized in the human body to glycerol and acetic acid, both of which are naturally occurring substances. It is considered non-toxic and is generally recognized as safe (GRAS) for use in food products.
Safety and Handling[edit]
While triacetin is considered safe for use in food and cosmetic products, it should be handled with care in its pure form. Appropriate safety measures should be taken to avoid inhalation or skin contact, and it should be stored in a cool, dry place away from incompatible substances.
