Applicant's summary and conclusion
- Conclusions:
- The log Pow of the test item was determined to be -2.6 at 20°C.
- Executive summary:
The n-octanol/water partition coefficient log Pow was investigated in a study conducted according to OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method; 1995) and EU Method A.8 (Partition Coefficient - Shake Flask Method; 2008). Based on the results of preliminary tests, the log Pow was determined via the solubilities of the test item in the pure solvents using HPLC/UV/VIS as analytical method. The log Pow of the test item was determined to be -2.6 at 20°C.
