Results and discussion
Partition coefficient
- Type:
- log Pow
- Partition coefficient:
- < -3.36
- Temp.:
- 25 °C
- pH:
- >= 6.6 - <= 6.77
- Details on results:
- The calculated log P of < -3.36 is significantly lower than the recommended range of the method (-2 to 4) however the reported result is regarded as being an acceptable value for the Log P of the test substance.
Applicant's summary and conclusion
- Conclusions:
- The Log P of the test material was determined to be <-3.36 at 25ºC +/- 1ºC in this study.
- Executive summary:
Introduction
This study was undertaken to determine the partition coefficient of the test material. This study method was in accordance with OECD Guidance 107.
Results & Conclusions
The Log P was determined to be <-3.36 at 25ºC +/- 1ºC in this study.
