Results and discussion
Partition coefficientopen allclose all
- Type:
- Pow
- Partition coefficient:
- > 3 200 000
- Temp.:
- 23 °C
- pH:
- 7
- Type:
- log Pow
- Partition coefficient:
- > 6.5
- Temp.:
- 23 °C
- pH:
- 7
- Details on results:
- The components of the test substance eluted in the gradient of the analytical method with retention times of > 30 minutes. The retention time of 2,4-DDT was 23.4 minutes. Hence, it was concluded that the log Pow of the components of the test substance was > 6.5 (Pow > 3.2 x 10^6).
Applicant's summary and conclusion
- Conclusions:
- The components of the test substance eluted in the gradient of the analytical method with retention times of > 30 minutes. The retention time of 2,4-DDT was 23.4 minutes. Hence, it was concluded that the log Pow of the components of the test substance was > 6.5 (Pow > 3.2 x 10^6).
