Preliminary estimates |
|
The preliminary test (saturation with each of the phases) leads to a value of log POw , of 18.8 with the following approximate solubility concentrations: |
|
-- 223 g/l in the octanol; 11.9g/l in the water (indications provided by the principal). |

Applicant's summary and conclusion
- Conclusions:
- The partition coefficient has been determined to be 5.92, log 10 Pow 0.772
- Executive summary:
Substances having a log10 Pow greater than 3 are regarded as having the potential to bioaccumulate in the enviroment.
