PRELIMINARY ESTIMATION OF THE WATER SOLUBILITY
The preliminary visual experiments showed that the water solubility of the test item is between 500 g/l and 1000 g/l. - Conclusions:
- Water solubility: 705.6 g/l at 20 °C
- Executive summary:
The water solubility of the test item was investigated in a study conducted according to OECD Guideline 105 and EU Method A.6. Flask method was used for this purpose, while UV VIS-spectroscopy was used for the detection of the concentration of the test item. Based on the findings of the study, the water solubility of the test item at a temperature of 20 °C was determined to be 705.6 g/l.
Conclusion
Water solubility: 705.6 g/l at 20 °C
