Description of key information

Log Kow: 3.18 at 22.5 °C

Key value for chemical safety assessment

Log Kow (Log Pow):
3.18
at the temperature of:
22.5 °C

Additional information

A log Kowvalue of 3.18 at 22.5 °C was determined by the shake-flask method according to EU Method A.8. In a supporting study by HPLC according to EU Method A.8 it is shown that the log Powvalue is not significantly influenced by the pH value when investigated at pH = 5, 7, 9 and 25 °C.
