Results and discussion
Partition coefficient
- Type:
- log Pow
- Partition coefficient:
- >= 2.6
- Temp.:
- 20 °C
- Remarks on result:
- other: pH not reported
- Details on results:
- The octanol solubility of the test item at 20°C was ≥ 777 g/L.
The Pow, calculated as the quotient of the n-octanol and critical micelle concentration, is ≥ 3.7 102. It corresponds with a log Pow value of ≥ 2.6.
Applicant's summary and conclusion
- Conclusions:
- The estimation method was applied for the determination of the partition coefficient (Pow) of CH04207.
The Pow value of the test item at 20°C was ≥ 3.7 * 10^2.
It corresponds with a log Pow value of ≥ 2.6.
