at the temperature of:
23.5 °C

Additional information

The n-octanol/water partition coefficient of the test material was determined in a study which was conducted under GLP conditions and in accordance with the standardised guideline EU Method A.8, using the shake-flask method. The study was assigned a reliability score of 1 in line with the criteria of Klimisch et al. (1997). 

Under the conditions of the study the Pow of the test material was determined to be 2112 at 23.5 °C, while the log Pow was determined to be 3.3246 at the same temperature.
