  • Is tetra-2 ethylhexyl pyromellitate safe?
  • They also noted that commercial TOTM contains DOTP, DEHP, di (2-ethylhexyl) isophthalate, and tetra (2-ethylhexyl) pyromellitate as impurities and assumed that if “impurities migrate pro-rata to a migration of the substance up to 5 mg/kg food, their estimated migration does not raise a safety concern.”
  • What are the characteristics of DOTP produced by esterification?
  • One of the distinctive features of DOTP produced by esterification is the qualitative stability of subsequent batches of the product in terms of transparency (colour).
  • Is DOTP a terephthalate isomer?
  • DOTP is a terephthalate isomer of DEHP, with similar plasticization abilities, but is subject to less regulatory restrictions and pressure due to reduced toxicity compared to traditional ortho -phthalate esters.
  • What is the difference between phthalate-based DEHP and DOTP?
  • One example of this trend is the substitution of phthalate-based DEHP by its non-orthophthalate counterpart DOTP (based on the same OXO alcohol), steadily expanding its share of the European PVC plasticiser market. However, the composition and properties of DEHT (DOTP) may vary, depending on the production method used.
  • Is terephthalic acid a surrogate for DBT?
  • The REACH registration file for DBT (ECHA, 2021a) appears to use read-across to terephthalic acid, dimethyl phthalate, or DOTP as surrogates; however, based on the available data for those substances, no health concerns were raised by US FDA. 3.2.3. Bis (2-ethylhexyl) cyclohexane-1,4-dicarboxylate (DEHCH) –CAS# 84731-70-4
  • How is DMT obtained from terephthalic acid (PTA)?
  • DMT can be obtained from terephthalic acid (PTA) or by alcoholysis of polyethylene terephthalate with methanol (recycling of PET products). The necessity of producing DMT from PTA or obtaining it from recycled PET can lead to the impurities being introduced with it.
