Description of key information

According to the OECD 117 the average partition coefficient (log Pow) of 8 fractions was determined to be 2.5 at 25°C in the range of 0.9 to 3.9. 

Key value for chemical safety assessment

Log Kow (Log Pow):
2.5
at the temperature of:
25 °C

Additional information

In order to ensure a stable performance of the HPLC column, the column temperature was set to 40°C. The reference Pow-values in the OECD guideline presumably refer to 25°C. Even though the column temperature was 40°C, this temperature has no influence on the result of the determination. Therefore the Pow -value of the test item determined within this study also refers to 25 °C.
