Results and discussion
Water solubility
- Key result
- Water solubility:
- > 1 000 g/L
- Conc. based on:
- test mat.
- Loading of aqueous phase:
- 1 110
- Incubation duration:
- 1 h
- Temp.:
- 20.1 °C
- Remarks on result:
- completely miscible
- Details on results:
- After the stirring period, the test solution was clear and visually no undissolved test item was observed.
It was concluded that the water solubility of the test item at 20°C was > 1 x 10^3 g/L.
Applicant's summary and conclusion
- Conclusions:
- The water solubility of the substance at 20°C was determined to be > 1000 g/L (flask method).
