  • How many producers of DIDP & DINP are there?
  • There are currently four producers of DIDP and DINP in the European Union. The estimated production in 1994 was around 200 000 tonnes of DIDP and 107 000 tonnes of DINP per year (for the then twelve EU Member States) and the amounts have probably increased since then. Around 95% of DIDP and DINP is used in PVC as a plasticizer.
  • What is DIDP & DINP used for?
  • Around 95% of DIDP and DINP is used in PVC as a plasticizer. More than half of the remaining 5% involves polymer -related uses other than PVC (e.g. rubbers). The remaining DIDP and DINP are used in non-polymer applications including anti-corrosion paints, anti-fouling paints, lacquers, inks, adhesives and sealants .
  • What is the LOQ of DINP and DIDP?
  • DINP and DIDP are mixtures of esters of o-phthalic acid, and were quantitated as a whole group against the internal standard DAP with the standard curve ranging from 2 mg/kg to 50 mg/kg. Quality control: The limit of quantitation (LOQ) was 0.001% for DBP, BBP, DEHP and DNOP. The LOQ was 0.005% for DINP and DIDP.
  • How many producers of DINP are there in the EU?
  • Approximately four producers of DINP exist in the EU. The estimated consumption volume in 1994 was ca. 107,200 t/a. An increase of the consumption of DINP is to be expected over the following years. Nearly all (95%) of DINP is used in PVC as a plasticizer. The remaining 5% are used in non-PVC applications.
  • What is the difference between DIDP and DINP?
  • Both DIDP and DINP can cause developmental toxicity and liver damage, but DINP is considered the more toxic of the two because effects are observed at lower levels of exposure in rodent models. For DIDP, EPA determined that the evidence is not strong enough to conclude that it can cause cancer in people.
  • Can EPA conduct a risk evaluation of DIDP & DINP?
  • The risk evaluations of DIDP and DINP are the first two manufacturer-requested risk evaluations EPA has conducted. Under TSCA, manufacturers can request that EPA conduct risk evaluations on chemicals they manufacture. EPA received and granted manufacturer requests for risk evaluations of DIDP and DINP in 2019.
