Effectiveness of triacetin and triethyl citrate as plasticizer
It was found that, at a fixed amount of plasticizer (10%), TRI caused reduction of glass transition temperature (Tg) and melt temperature (Tm) in both PVA with the largest reduction in 88% hydrolysed PVA while TEC showed insignificant changes of Tg and slight reduction of Tm suggesting higher effectiveness of plasticization in 88% hydrolysed PVA
Triacetin as a Secondary PVC Plasticizer | SpringerLink
The use of biobased plasticizers with low toxicity and good compatibility with polyvinyl chloride (PVC) has become more attractive in the recent years in contrast with phthalate derivatives. In this study, a glycerol derivative plasticizer (triacetin—TAG) was tested as a secondary plasticizer for PVC.

Triacetin
Triacetin is a common food additive, for instance as a solvent in flavourings, and for its humectant function, with E number E1518 and Australian approval code A1518. It is used as an excipient in pharmaceutical products, where it is used as a humectant, a plasticizer, and as a solvent. [8] Potential uses [ edit]
Plasticizers: Types, Uses, Classification, Selection & Regulation
The most widely used internal plasticizer monomers are: Vinyl acetate Vinylidene chloride But this technique is limited: every copolymer is only suited to certain flexibility requirements Also, the complexity of the reaction can lead to longer reaction times and increased costs.
- How much triacetin is used to make a solvent evaporated ASD?
- Moreover, we observed that as little as 10 % w/w of triacetin led to the form conversion of solvent-evaporated ASD based on the probucol drug. The amount of plasticizer used in commercially available film coatings for oral tablets is 8–20 % w/w.
- Does triacetin & PEG 3350 Leach a film coated oral tablet?
- Two plasticizers commonly used film coatings for oral tablets, triacetin and PEG 3350, were assessed. A tri-layered tablet to mimic an actual film coated oral tablet was made. Using it, the leaching propensity between triacetin and PEG 3350 after stressing the tri-layered tablet at different stability conditions for 1 week was studied.
- Does triacetin affect the physical stability of ASDs?
- Further, for practical assessments of the impact of triacetin on the physical stability of ASDs, we evaluated the propensity of triacetin leaching in Drug-1 SDI using a tri-layered compact methodology similar to Section 3.1, replacing the middle HPMC layer with Drug-1 SDI and stressing at 40 °C/75 % RH for 1 week.
- Is tri a good plasticizer?
- A few researchers incorporated TRI or TEC as plasticizer in polymers such as PLA [7, 8] and PVC with reported reduction of glass transition temperature and melting temperature suggesting improvement in flexibility and processibility.
- Does triacetin containing ASD lead to crystallization of probucol at 50 % W/W DL?
- We found that triacetin containing ASD led to the crystallization of probucol at 50 % w/w DL; such crystallization was not observed in the case of PEG 3350 or the absence of plasticizers at the same drug loading (Fig. 4, Fig. 5).
- How is triacetin produced?
- Triacetin (TAG) can be obtained by acetylation of biodiesel glycerol (see Scheme 1) using acetic acid or anhydride acetic. The efficient and selective acetylation of glycerol can be achieved in the presence of magnetic solid acids as catalysts . Moreover, it can be produced from the glycerol derived from the biodiesel production.
