Potential uses: The plasticizing capabilities of triacetin have been utilized in the synthesis of a biodegradable phospholipid gel system for the dissemination of the cancer drug paclitaxel (PTX).
In the study, triacetin was combined with PTX, ethanol, a phospholipid and a medium chain triglyceride to form a gel-drug complex.
This complex was then injected directly into the cancer cells of glioma-bearing mice.
The gel slowly degraded and facilitated sustained release of PTX into the targeted glioma cells.
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.
It has been considered as a possible source of food energy in artificial food regeneration systems on long space missions.
E1518 (Glyceryl Triacetate) is believed to be safe to get over half of one's dietary energy from triacetin.
Triacetin(Glycerol triacetate) also known as E1518 (Glyceryl Triacetate), is pharmaceutical excipient used in manufacturing of capsules and tablets, and has been used as a humectant, plasticizer, and solvent. It is a liquid, and has been approved by the FDA as a food additive. Triacetin is a water-soluble short-chain triglyceride that may also have a role as a parenteral nutrient according to animal studies.
E1518 (Glyceryl Triacetate) is also used in the perfume and cosmetic industries.
Synthesis: E1518 (Glyceryl Triacetate) was first prepared in 1854 by the French chemist Marcellin Berthelot.
Triacetin was prepared in the 19th century from glycerol and acetic acid.
Its synthesis from acetic anhydride and glycerol is simple and inexpensive.
3 (CH3CO)2O + 1 C3H5(OH)3 → 1 C3H5(OCOCH3)3 + 3 CH3CO2H
This synthesis has been conducted with catalytic sodium hydroxide and microwave irradiation to give a 99% yield of triacetin.
It has also been conducted with a cobalt(II) Salen complex catalyst supported by silicon dioxide and heated to 50 °C for 55 minutes to give a 99% yield of triacetin.
Safety:The US Food and Drug Administration has approved it as Generally Recognized as Safe (GRAS) food additive and included it in the database according to the opinion from the Select Committee On GRAS Substances (SCOGS).
"Triacetin and two types of acetooleins have been found to be without toxic effects in long-term feeding tests in rats at levels that were several orders of magnitude greater than those to which consumers are exposed.
Three types of acetostearins have been found to be without toxic effects in long-term feeding tests in rats at levels up to 5 g per kg per day.
This contrasts with an estimated human consumption of a fraction of a milligram per kg per day.
It is recognized that at an even higher feeding level (10 g per kg per day) male rats developed testicular atrophy and female rats, uterine discoloration.
However, such a level which would amount to 50 g or more for an infant and 600 g for an adult per day, is vastly higher than would be possible in the consumption of foods to which acetostearins are added for functional purposes."
Triacetin is included in the SCOGS database since 1975. Triacetin was not toxic to animals in studies of exposure through repeated inhalation over a relatively short period.
Uses:
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.
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.
The triacetin is applied to the filter as a plasticizer.
It has been considered as a possible source of food energy in artificial food regeneration systems on long space missions.
