Results and discussion

Water solubility
Water solubility:
> 1 000 g/L
Temp.:
20 °C
pH:
13.5
Details on results:
Test substance was stirred with double distilled water at a nominal concentration of 1080 g/l at 20.3 +/- 0.5°C for 18.8 hours. After the stirring period, the test sample was clear and colourless, and no undissolved test substance was observed.
