Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The column elution method was chosen for the determination of the water solubility of ASA404 C8. The water solubility of the test substance at 19.9°C +/- 0.4°C was 1.35 x 10-3 g/l. The pH of the aqueous samples was 7.2 - 7.3.
