Uses
E1518 Triacetin 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.
E1518 Triacetin is used as an excipient in pharmaceutical products, where E1518 Triacetin is used as a humectant, a plasticizer, and as a solvent.
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.
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.
