Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The key value was determined to be 9.96 at 25 °C by QSAR estimation (EPIWIN/KOWWIN v1.68 by US-EPA) (2011). 
Further, the partition coefficient of tris(2-ethylhexyl) 2-(acetyloxy)propane-1,2,3-tricarboxylate was determined in a non-GLP study (2011) according to EU Method A.8. Using the HPLC method the partition coefficient was reported to be > 5.7 at 23 °C. A more precise value could not be obtained during this test, so the calculated value was taken as key value for chemical safety assessment.
