Plasticizers: What is the difference between DEHT and DEHP – Oxoplast Germany

Esterification vs. transesterification – comparison of DEHT

14/12/2017 · In this paper, we will look into DEHT production methods and indicate significant differences that may influence on the DEHT quality. Two primary methods for the production of di-esters used as plasticizers are the following: esterification (employed by Grupa Azoty ZAK S.A. for production of Oxoviflex® (DEHT, DOTP) ) and transesterification (employed by some other manufacturers). Use of Plasticizers and Their Regulatory ImplicationsWhich plasticizers are being used? Globally, DEHP (DOP) is still the number one plasticizer produced and used at ~37% DINP is next at ~16% DEHT (DOTP), the main phthalate -alternative, is ~12% Several other phthalates and alternatives make up the

Kerstin Becker et al. “DEHP metabolites in urine of children and DEHP in house dust and alternative plasticizers in indwelling medical devices in pediatric intensive care units – 5/2/2019 · The present study aimed to identify plasticizers present in indwelling plastic medical devices commonly used in the pediatric intensive care unit (PICU). We have analyzed a wide range of medical devices (n = 97) daily used in the PICUs of two academic hospitals in Belgium and the Netherlands.

The results showed a predominance of TOTM in PVC MDs accompanied by DEHP (<0.1% w/w), DEHT, and sometimes DEHA. The migration tests showed a difference in the migration

Analysis of plasticizers in poly(vinyl chloride) medical

11/1/2015 · Medical devices (MDs) for infusion and enteral and parenteral nutrition are essentially made of plasticized polyvinyl chloride (PVC). The first step in assessing patient exposure to these plasticizers, as well as ensuring that the MDs are free from di(2-ethylhexyl) phthalate (DEHP), consists of identifying and quantifying the plasticizers present and, consequently, determining which ones are Analytical methods for the determination of DEHP plasticizer alternatives present in medical Moreover, the lower leaching aptitude into oily media of DEHT (i.e ethanolic simulant) compared to other studied plasticizers [14] could have influenced the interactions between DEHT and the simulant.

plasticizers in German freshwater environments – Evidence for the

We found large differences between the individual locations. In samples from the mid-2000s concentrations of all investigated plasticizers ranged between 936 ng/g dw (E5) and ng/g dw on loss of plasticizers, on crystalline features and on An intermediate behavior between that shown by the PP-DEHP and PP-DEHT is exhibited in the PP-DINCH material, as seen in Figure 2. After 8 days of permanence at 95°C, the PP-DINCH film

Experimental studies on DEHT have produced low toxicity in rats, mice, and guinea pigs [14, ].

dehp plasticizer | What is DEHP? Where is it used? Why is it

Due to its suitable properties and the low cost, DEHP is widely used as a plasticizer in manufacturing of articles made of PVC. Plastics may contain 1% to 40% of DEHP. It is also used as a hydraulic fluid and as a dielectric fluid in capacitors. In vitro and in silico hormonal activity studies of Differences between the DEHP and DEHT metabolites were observed. Albeit weak, the hormonal activities of DEHT-derived metabolites, e.g., 5-OH metabolite of mono-(ethylhexyl)terephthalate (5-OH-MEHT), were detected and the results of docking experiments performed on estrogen receptor alpha and androgen receptor agreed with the biological results.
