- Partition coefficient:
- > 4.3
- Remarks on result:
- other: pH and temperature not stated
- Conclusions:
- The Pow value of the test item was estimated to be > 2.16 x 10E+04, which corresponds to a Log Pow value of > 4.3.
- Executive summary:
METHODS
Since the test item is a surface active UVCB (estimated surface tension of 48 nM/m), neither the Shake Flask method nor the HPLC method are recommended. Therefore, the estimation method was performed.
RESULTS
The Pow value of the test item was estimated to be > 2.16 x 10E+04, which corresponds to a Log Pow value of > 4.3.
Reference
- The octanol solubility was visually seen to be > 1000 g/L.
- Previously determined water solubility was used for calculation of the partition coefficient.
Description of key information
The Pow value of the test item was estimated to be > 2.16 x 10E+04, which corresponds to a Log Pow value of > 4.3 (EU Method A.8).
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 4.3
- at the temperature of:
- 25 °C
