Applicant's summary and conclusion
- Conclusions:
- The Log Pow of the test substance is -0.31 at 23°C.
- Executive summary:
The partition coefficient n-octanol/water was determiend according to OECD 107 with the shake flask method. 10, 20 and 40 ml of a stock solution in water saturated n-octanol was shaken with 20 ml water (in duplicate) at 23 °C and the concentration of the test substance was determiend by UV-vis-spectroscopy.
