Results and discussion

Water solubility
Water solubility:
> 1 100 g/L
Temp.:
20.3 °C
pH:
2.2
Details on results:
A mixture of 1.1g MMC and 1 ml double distilled water was stirred for 1 day at20.3 ± 0.5°C. After the stirring period, the solution was clear and no
undissolved test substance was observed visually. Based on this, it was concluded that the water solubility of MMC is > 1.1 x10E3 g/I at
20.3 ± °C. The pH was measured to be 2.2.
