Key result
Type:
log Pow
Partition coefficient:
> 5.5
Temp.:
20 °C
Remarks on result:
other: pH not applicable (estimation method)

The partition coefficient was calculated as the quotient of the n-octanol solubility and the water solubility.

Description of key information

Log Pow > 5.5 at 20°C (based on n-octanol solubility (OECD 117, EU A8) and water solubility (OECD 105, flask method)

Key value for chemical safety assessment

Additional information

Value was calculated based on solubilities determined in water and octanol.
