Results and discussion
Partition coefficient
- Key result
- Type:
- log Pow
- Partition coefficient:
- 5.9
- Temp.:
- 30 °C
- pH:
- 7
- Details on results:
- The determination was performed at 30°C (column temperature), however the values can be considered to represent the values at an unspecified, probably ambient temperature since no mention is made in the guidelines of the temperature at which the tabulated reference substances log Kow values were determined. Partition coefficients of the test and reference substances are assumed to vary with temperature in the same way.
Applicant's summary and conclusion
- Conclusions:
- The partition coefficient n-otctanol/water of Amberketal is Log Pow = 5.9.
- Executive summary:
The partition coefficient n-otctanol/water of Amberketal has been determined by the Reverse Phase High Performance Liquid Chromatographic Method according to the OECD 117
The results is Log Pow = 5.9
