Results and discussion
Partition coefficient
- Key result
- Type:
- log Pow
- Partition coefficient:
- 3.7
- Temp.:
- 25 °C
- Remarks on result:
- other: pH not specified
- Details on results:
- The average of the measured log Pow of the test item was 3.7 and the difference between two measured values was 0.0. It is judged that the results are valid because the difference between two measures values is less than ± 0.1.
Applicant's summary and conclusion
- Conclusions:
- The partition coefficient of the test item has been determined to be: log Pow = 3.7 (25°C).
