55 °C

Additional information

The partition coefficient of the substance triisotridecyl benzene-1,2,4 -tricarboxylate (CAS 72361-35-4) was determined according to the OECD Guideline 117 and other guidelines. The calculated log Pow value of 18.96 (KOWWIN v1.68) supports the conclusion that the substance is highly lipophilic. It is believed that log Pow does not dependent significantly on the temperature, thus the result at 55 °C can be accepted for risk assessment.
