The triglyceride 1,2,3-triacetoxypropane is more generally known as triacetin and glycerin triacetate. It is the triester of glycerol and acetic acid.

Additional recommended knowledge

It is an artificial chemical compound, commonly used as a food additive, for instance as a solvent in flavourings, and for its humectant function, with E number E1518 and Australian approval code A1518. Triacetin is also a component of casting liquor with TG.

Triacetin can also be used as a fuel additive as an antiknock agent which can reduce engine knocking in gasoline, and to improve cold and viscosity properties of biodiesel.

In a 1994 report released by five top cigarette companies, triacetin was listed as one of the 599 cigarette additives. [1] The triacetin is applied to the filter as a plasticizer. [2]

Because it is in some sense the simplest possible fat, it is being considered a possible source of food energy in artificial food regeneration systems on long space missions. It is believed to be safe to get over half of one's dietary energy from triacetin.[citation needed]
