Applicant's summary and conclusion
- Conclusions:
- The partition coefficient logPow was determined in a GLP guideline study according to OECD 107 without deviations on the registered substance itself. The study must hence be considered reliable, validity criteria were fulfilled. The pH value of the aqueous buffer phases varied between 6.01 and 6.32. The partition coefficient was determined at 23 °C to log Pow = -0.61.
- Executive summary:
The partition coefficient of the test item was determined according to OECD Guideline for the testing of chemicals 107 to Pow = 0.2454 (standard deviation 0.09890), and log Pow = -0.61, using the shake flask method and HPLC analysis. The pH value of the aqueous buffer phases varied between 6.01 and 6.32. The partition coefficient was determined at 23 °C.
