Description of key information
Partition coefficient (Log10): 9.3
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 9.3
- at the temperature of:
- 55 °C
Additional information
The partition coefficient, determined using the HPLC method in accordance with EPA, OECD and EU test methods, has been determined as: Log10 Pow = 9.3 (T= 55 deg C).
A supporting study reports a calculated value of Log10 Pow = 12.06 (T= 25 deg C).
