The determination of the log Pow using the
respective OECD guideline methods was technically not feasible due to
the intrinsic properties of the test item:
- The test item is a UVCB and the
flask-shake (OECD TG 107) and slow-stir method (OECD TG 123) for
determination the log Pow are not applicable to complex mixtures.
- The test item cannot be chromatographed
under the conditions described in the HPLC-method (OECD Guideline 117)
since it is insoluble in the solvents used for the reverse phase HPLC.
- The test item has no defined chemical
structure; therefore the calculation of the log Pow with a QSAR tool is
Hence, the log Pow has to be estimated based
on individual solubilities of the test item in water and n-octanol.
Considering the water solubility of 4.1 mg/L and the n-octanol
solubility of < 0.5 mg/L a log Pow of <0.9 has been estimated
