Triacetin can also be used as a fuel additive which can reduce knocking in gasoline and 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 additives to cigarettes. [1] The triacetin is applied to the filter as a plasticizer. [2] Plasticizers are additives that soften the materials (usually a plastic or a concrete mix) they are added to. ...

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]} Food energy is the amount of energy in food that is available through digestion. ...
