Log partition coefficient for the substance is >5.6.
An attempt was made to determine partition coefficient for this substance using the shake-flask method, but a sample-water-octanol emulsion formed in the aqueous phase and the test had to be terminated. Partition coefficient was therefore estimated based on the individual solubilities of octanol and water (Chilworth 2012) and a log Kow of >5.6 was determined.
Partition coefficient was also measured for this substance in a GLP-compliant study following OECD guideline 117, HPLC method (Hamilton Garrod 1995). As this test method is not considered to be appropriate for this substance, due to the surface active nature of the test item, this is used as a supporting study only. This study determined that the log Kow for this substance is in the range 3.08 - >6.
