Diverging trends of plasticizers (phthalates and non
In recent house dust samples, Di (2-ethylhexyl) terephthalate (DEHT) had the third highest concentration of all plasticizers and contributed 18% to the total load, whereas Tris (2-ethylhexyl) trimellitate (TOTM) was one of the major non-phthalates in SPM samples. Conclusions
Analytical methods for the determination of DEHP plasticizer
The excellent performance of DEHP in the plasticization and processing of PVC explains its wide use in medical devices over the past few years. The strategy was to adjust the chemical nature of the lateral alkyl chains in order to reduce the leaching of the plasticizers into the surrounding medium.

DEHP levels in plasma collected in vacutainers were also low, although it was noted that the concentrations could reach as high as 2.6 μM. Other sources of DEHP or similar plasticizer contact are possible even in this collection method which would require further investigation, but the contamination was not nearly as significant as in the
Simultaneous determination of plasticizer di(2-ethylhexyl
It also exhibited high sensitivity with the limits of detection at 0.96 μg L 1 and 3.2 μg L 1 for MEHP and DEHP, respectively. The calibration curves were linear in the concentration range of 20–1920 μg L 1 for MEHP and 60–1920 μg L 1 for DEHP, with the correlation coefficients higher than 0.9990. The proposed method can be
A potentially general approach to aliphatic ester-derived PVC
This approach harnesses the α-proton, a structural feature shared by all aliphatic esters, and dialkyl carbonate, an established “green chemical”, thus providing a potentially general and green route towards DEHP alternatives with unprecedented performance that may contribute to sustainability of the old and oft-maligned PVC industry.
- Why is DEHP a good plasticizer?
- Phthalates play an important role in plastics and rubber around the world, accounting for more than 80% of all PVC plasticizers, and DEHP represents at least 60% of this amount due to its good performance and low price.
- Which plasticizer is most commonly used?
- Di- (2-ethylhexyl)-phthalate (DEHP) has been the most widely used plasticizer since its introduction in 1930. However, the non-covalent bond between DEHP (or plasticizers in general) and polymers mean they can be leached when they enter into contact with fluids containing lipophilic compounds .
- What happens if you eat plasticizer DEHP?
- Plasticizer DEHP ( Fasano, Bono-Blay, Cirillo, Montuori, & Lacorte, 2012) is a toxic plastic softener widely used in chemical industry that can make the distribution of particles more uniform and increase the ductility, elasticity and softness. However, if DEHP is eaten by human, it may affect the liver and kidney, and even cause cancer.
- Can a simple method be used to determine DEHP in drink?
- Based on the results obtained, it was clear that the developed method, with advantages of simple, rapid, sensitive and selective could be successfully applied for the determination of DEHP in drink.
- Which plasticizer has better tensile strength?
- The plasticizers ATBC, DEHT and polyadipate showed lower plasticization efficiency than the others since samples 2, 4 and 6 showed the highest tensile strength values. The vegetable oil-based plasticizers showed better mechanical performance (values similar/near to DEHA) than the other plasticizers evaluated.
- Which plasticizers are used in food packaging?
- DEHA di (2-ethylhexyl) adipate), ESBO (epoxidized soybean oil), ATBC (acetylated tributyl citrate) and polymeric plasticizers are used in plastic packages for food (the last two plasticizers are used mainly in Europe due to their high cost) and are not hard to find in packages available in the market.
