Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The partition coefficient (n-octanol/water) of Triisodecylbenzene-1,2,4-tricarboxylate CAS No 36631-30-8 has been determined to be greater than 2.5 x 109, log10 Pow greater than 9.4, using the HPLC method.

Guideline 117 states that the HPLC method covers log Pow values in the range of 0 to 6, however, these results are considered valid as a reference substance with a higher known log Pow value outside of those listed in the guideline has been used in this study (1-Phenyltridecane, which has a log Pow of 9.4), in order to obtain a meaningful result via extrapolation.
