Description of key information

Litterature data, no Guideline, no GLP, key study, validity 2:
Log Kow =3.75

Key value for chemical safety assessment

Log Kow (Log Pow):
3.75
at the temperature of:
20 °C

Additional information

Experimental and litterature data are available to determine the octanol-water partition coefficient of TBEP.

The key value for the Log Kow of TBEP is 3.75. Other higher values could be found in secondary references but the original references and the rationales for these higher values could not be found.

Finally the 3.75 value is supported by a QSAR calculation which gives a calculation of 3.00 based on a fragment constant methodology.
