Any other information on results incl. tables

In the chromatogram of the test item solution, no peak was observed. Under the same analytical conditions, the retention time of benzo[ghi]perylene (log Pow = 7.2)

was 16.815 and 15.964 minutes. When the test item was injected under the same analytical conditions with no column there was a response observed. Hence, it was concluded that the log Pow of test item

was > 7.2 (Pow > 1.6 x 10^7).

Applicant's summary and conclusion

Conclusions:
The HPLC method was applied for the determination of the partition coefficient (Pow) of the test substance.

The Pow and log Pow value of the test item at neutral pH was > 7.2 (Pow > 1.6 x 10^7).
