Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

partition coefficient
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
accepted calculation method
Principles of method if other than guideline:
The solubility of the substance was measured separately in n-octanol and in water using the shake flask method. The results of these studies were then used to calculate the Log Kow.
GLP compliance:
Type of method:
other: Estimated based on the solubility in n-octanol and in water
Partition coefficient type:
log Pow
Partition coefficient:
20 °C
Remarks on result:
other: Solubility in water = 15.31 g/L; solubility in n-octanol = 7.43 g/L

Description of key information

The Log Kow was estimated to be -0.31, based on the solubility of the substance in n-octanol and in water.

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

The Log Kow was estimated based on the measured solubility of the substance in n-octanol (7.53 g/L) and in water (15.31 g/L) at 20 °C. This resulted in a Log Kow of -0.31.
