Applicant's summary and conclusion

Conclusions:
The study was performed according to OECD TG 107 under GLP on the substance to be registered itself, the test procedure is well documented and therefore reliability of Klimisch 1 has been assigned. OECD 107 states that the six determined log Pow values should fall within a range of ± 0.3 units. This criterion is fulfilled, and the partition coefficient can be reported as total average over six independent determinations:
Pow = 753.7 (standard deviation 178.3)
log Pow = 2.88
The pH value of the aqueous buffer phases varied between 3.0 and 3.2. The partition coefficient was determined at 23 °C.
Executive summary:

The partition coefficient of the test item was determined according to OECD Guideline for the testing of chemicals 107 under GLP, shake flask method.

Results:

Pow = 753.7 (standard deviation 178.3)

logPow = 2.88

The pH value of the aqueous buffer phases varied between 3.0 and 3.2. The partition coefficient was determined at 23 °C.
