Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Respiration inhibition:NOEC - 1077 mg/L
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 1 077 mg/L
Additional information
A respiration inhibition test with activated sludge has been conducted on a structurally similar trimellitate, tri(2 -ethylhexyl)trimellitate (TOTM). A limit concentration of 1000 mg/L was investigated. No inhibition was observed and the NOEC was regarded as being 1000 mg/L. Adjusting for differences in molecular weight between the tested substance and the registered substance, this value equates to a NOEC of 1077 mg/L.
Potential nitrification inhibition by the registered substance itself has been determined using an activated sludge nitrification inhibition test. No inhibition of nitrification was observed in saturated solutions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
