Description of key information

Method A.8, Partition coefficient, Directive 92/69/EEC, Published in OJ No L 383 A, 1992. 
GLP study.

Key value for chemical safety assessment

Log Kow (Log Pow):
-2.16
at the temperature of:
20 °C

Additional information

The partition coefficient of the test substance was determined. The shake-flask method was used.

The test was performed according to the Method A.8, Partition coefficient, Directive 92/69/EEC, Published in OJ No L 383A, 1992.

Partition coefficient (log P) of the test substance - Humic acids, potassium salts - determined by shake-flask method is:

log Pow = -2.16 ± 0.45 (pH = 9.1, 23ºC)

The partition coefficient shows some suggestion of concentration dependency.
