Effect of thermo-oxidation on loss of plasticizers,
Fig. 2 also clearly displays that PP-TOTM material is the one where plasticizer remains in a very significant content at this high temperature for 16 days. Difference with the PP-DEHT, which is the next in preservation of plasticizer, is rather important: a content of around 88% of TOTM is kept versus approximately 22% of DEHT.

However, the absolute plasticizer migration rate of TOTM (TOTM equivalents) after 24 h of perfusion was found to be significantly lower compared to that of DEHP (with a factor of over 200).

bag systems, platelet pool bags, transfusion systems, enteral and parenteral tubing sets, haemodialysis tubing sets, tubolars, endotracheal tubes, valves and connectors. Exposure to plasticizers is due to a migration process, whose rate may be controlled both by the ease of loss from the PVC surface and by the rate of diffusion of plasticizer

Replacing Di(2-ethylhexyl) Terephthalate by Di(2-ethylhexyl
Consequently, non-phthalate plasticizers have become more widely used (see Reference and references therein). This is the case for di(2-ethylhexyl) terephthalate ester (DEHT), DEHP structural isomer, but it is not associated with toxic effects . However, the DEHT plasticizer (or even DEHP) is derived from fossil resources.

Softness and flexibility of PVC are due to the addition of plasticizers in high concentration; the most used of them for blood storage bags is DEHP. In this work, a method for labelling DEHP with
Analytical methods for the determination of DEHP plasticizer
For example DEHA, which has a lower molecular weight, evaporates at a lower temperature than DINP [37]. Rahman et al. studied the high temperature stability of some plasticizers in 20 wt% plasticized PVC samples using TGA [40]. TOTM appears to be the most stable plasticizer in short-term and long-term thermal stability studies (Fig. 2) [40].
