Effectiveness of triacetin and triethyl citrate as
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
In this study, a glycerol derivative plasticizer (triacetin—TAG) was tested as a secondary plasticizer for PVC. TAG was added to PVC formulations from 10 up to 20 phr. The increase of the plasticizer content had a great influence on the properties of PVC samples.

Final report on the safety assessment of triacetin - PubMed
Triacetin, also known as Glyceryl Triacetate, is reported to function as a cosmetic biocide, plasticizer, and solvent in cosmetic formulations, at concentrations ranging from 0.8% to 4.0%. It is a commonly used carrier for flavors and fragrances. Triacetin was affirmed as a generally recognized as s
Triacetin
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). [9] In the study, triacetin was combined with PTX, ethanol, a phospholipid and a medium chain triglyceride to form a gel-drug complex.
- What is Eastman triacetin used for?
- It serves as an ingredient in inks for printing on plastics, and as a plasticizer in nail polish. For food additive applications, Eastman supplies Eastman™ Triacetin, Kosher, Food Grade, and Eastman™ Triacetin, Food Grade, which are made under appropriate current good manufacturing practices (cGMP) for these applications.
- 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.
- 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.
- Can glycerin acetate be used to plasticize PVC?
- The use of glycerol derived plasticizers has been reported to provide PVC with excellent mechanical properties . Mixtures of glycerin acetates have been reported to afford the same plasticization efficiency as di (2-ethylhexyl) adipate) (DEHA) .

- What are secondary plasticizers?
- Secondary plasticizers are additives which, when combined with the primary plasticizers, can improve the properties of the final material . In the present work, a glycerol derivative (triacetin—TAG) was used as PVC secondary plasticizer.
