The triglyceride 1,2,3-triacetoxypropane is more generally known as triacetin and glycerin triacetate. It is the triester of glycerol and acetic acid.
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 and as an excipient in pharmaceutical products where it is used as a humectant, a plasticizer, and as a solvent.[2]
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.[3]
Because it is in some sense the simplest possible fat after glyceryl triformate, it has been considered as 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.[4]
