Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on a weight of evidence approach, water solubility is estimated to be <0.0054 µg/L at 20 deg. C and pH 7.
Key value for chemical safety assessment
- Water solubility:
- 0.005 µg/L
- at the temperature of:
- 20 °C
Additional information
The solubility of triisononyl benzene-1,2,4-tricarboxylate at 20 ± 0.5 °C was determined to be lower than 1 mg/L in a screening study. The experimental water solubility for a similar substance, tri-isooctyl trimellitate (TIOTM) was determined to be < 0.0054 ug/L, conservatively based on the highest measured value. This is in agreement with the QSAR estimate (WSKOWWIN) for TINTM (using a measured logKow value of 9.9) of 0.00067 µg/L. Based on these two independent lines of evidence, the water solubility of TINTM is conservatively estimated to be < 0.0054 µg/L at 20 degrees C and pH = 7.
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.
