Applicant's summary and conclusion
- Conclusions:
- The determined partition coefficient of test item at 20.8 ± 1 °C is log Pow <-2.
- Executive summary:
The n-octanol/water partition coefficient of the test item was determined according to OECD guideline 107 and EC method A.8 (440/2008/EEC). For the determination of the n‑octanol/water partition coefficient of the test item the shake-flask method was used. The main test was performed in water at three different ratios of n-octanol and water (1/1, 2/1 and 1/2).
The concentration of the test item in the water phase and in the n‑octanol phase was taken for the calculation of n‑octanol/water partition coefficient (Pow) and its decimal logarithm (log Pow). The determined partition coefficient log POW at 20.8 ± 1 °C is < -2 (below determination limit of the method).
The pH values of the water phases after shaking were determined to be between 8.13 and 8.17.
