- Conclusions:
- Under the conditions of the study, the Log Pow of the registered substance is determined to be 1.6.
- Executive summary:
The partition coefficient n-octanol / water (Pow) of the substance was studied according to OECD guideline no. 117 and EU test method A.8 with the HPLC method. As the substance is a UVCB, four peaks were identified in the HPLC chromatogram and individual values of Log Pow were calculated. For determination of the overall Log Pow for the UVCB substance, the area-% weighted log Pow was calculated according to guideline recommendations. The Log Pow of the substance is determined to be 1.6.
