Description of key information

The determination was carried out using the HPLC method, designed to be compatible with Method A8 Partition Coefficient of Commission Regulation (EC) N° 440/2008 of 30 May 2008 and Method 117 of the OECD Guidelines for Testing of Chemicals, 13 April 2004. The test system consisted of a high performance liquid chromatograph (HPLC) with suitable detectors. A reverse phase HPLC column with a very low percentage of polar groups was used (e.g. C8, C18). The mobile phase contained at least 25% aqueous phase. 
The partition coefficient of the test item has been determined to be greater than 1.59 x 107, log10 Pow, greater than 7.20.
