Bis(2-ethylhexyl) terephthalate
Bis (2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. It is a non- phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is referred to as octyl.
CPSC Staff Statement on University of Cincinnati Report
Di(2-ethylhexyl) terephthalate (DEHT) is a U.S. EPA high production volume chemical, with production above 50 million pounds/year in the U.S. (SCENIHR, 2008). Because it can be used as a substitute for DEHP, and other regulated or restricted plasticizers, consumption volume is increasing.

Exposure to di-2-ethylhexyl terephthalate in the U.S. general
Method: We quantified two DEHTP metabolites, mono-2-ethyl-5-hydroxyhexyl terephthalate (MEHHTP) and mono-2-ethyl-5-carboxypentyl terephthalate (MECPTP) in 2970 urine samples by using online solid-phase extraction coupled with isotope dilution-high-performance liquid chromatography-tandem mass spectrometry. We used linear regression to examine

- What is DEHT (Dioctyl terephthalate)?
- Bis (2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. It is a non- phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is often generically referred to as octyl.
- What is Di 2 ethylhexyl terephthalate used for?
- The hydrolysis and metabolism of di (2-ethylhexyl) terephthalate were found to be similar to those of di (2-ethylhexyl) adipate in that hydrolysis of both ester bonds occurs. Used as plasticizer and as a softener for nitrile- butadiene rubber, chloroprene rubber, and isobutylene - isoprene rubber; [HSDB]
- How is bis 2 ethylhexyl terephthalate removed from the atmosphere?
- Particulate-phase bis (2-ethylhexyl) terephthalate will be removed from the atmosphere by wet or dry deposition. Bis (2-ethylhexyl) terephthalate does contain chromophores that absorb at wavelengths >290 nm and therefore may be susceptible to direct photolysis by sunlight.
- What is a standard state of terephthalate?
- Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Bis (2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2.
- How is bis (2-ethylhexyl) terephthalate exposed?
- Occupational exposure to bis (2-ethylhexyl) terephthalate may occur through inhalation of aerosols and dermal contact with this compound at workplaces where bis (2-ethylhexyl) terephthalate is produced or used.
- Does bis (2-ethylhexyl) terephthalate have mobility in soil?
- TERRESTRIAL FATE: Based on a classification scheme (1), an estimated Koc value of 2,000 (SRC), determined from a water solubility of 4.0 mg/L (2) and a regression-derived equation (3), indicates that bis (2-ethylhexyl) terephthalate is expected to have slight mobility in soil (SRC).
