Applicant's summary and conclusion
- Conclusions:
- The log Pow of the test item was determined to be 0.1 at 23°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) using the shake-flask method based on preliminary tests. In the main test six separating funnels were prepared containing 20 mL of a stock solution of the test item, pre-saturated water in amounts of 0 and 20 mL and pre-saturated n-octanol in amounts of 20 and 40 mL, respectively. Based on the test item concentrations in the aqueous and octanol phases measured via HPLC/UV/VIS, the log Pow was determined to be 0.1 at 23°C.
