partition coefficient
Type of information:
experimental study
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Recent guideline study not to GLP
according to guideline
EU Method A.8 (Partition Coefficient)
Principles of method if other than guideline:
The solubility of the substance in n-octanol and water was separately determined then the Pow calculated as n-octanol solubility/water solubility.
GLP compliance:
Type of method:
other: Ratio of measured solubilities
Partition coefficient type:
Key result
log Pow
Partition coefficient:
> 0.51
20 °C
Remarks on result:
other: Determined by ratio of solubilities in n-octanol and water
Details on results:
The solubility in n-octanol was determined to be >750 g/L at 20 degC. The water solubility was determined to be >230 g/L. Therefore the Pow is calcuated as >750/230 = > 3.26. Therefore the log Pow is >0.51
The substance has a log Pow of >0.51
Executive summary:

In a non-GLP study conducted in line with EU Method A.8, the test material was found to have a log Pow of >0.51.
