Results and discussion
Water solubility
- Water solubility:
- ca. 620 g/L
- Conc. based on:
- test mat.
- Loading of aqueous phase:
- 620 g/L
- Incubation duration:
- ca. 10 min
- Temp.:
- 20 °C
- pH:
- ca. 7
- Remarks on result:
- other: pH of water not recorded
Applicant's summary and conclusion
- Conclusions:
- Water solubility is greater than or equal to 620 g/L.
- Executive summary:
62g of sample was weighed into a weighing boat on a 4 figure balance, 100ml of water was added and then stirred for 10 minutes. The sample was completed dissolved, this is the maximum tested concentration there solubility is at least = 620 g/L
