Results and discussion
Water solubility
- Water solubility:
- > 300 g/L
- Temp.:
- 21 °C
- pH:
- ca. 8.4
- Details on results:
- Analytical method: Visual observation.
Any other information on results incl. tables
The material has a high water solubility. It was not
possible to prepare samples at five times the saturation
level as recommended in the guideline. No analysis was
performed as the viscous solutions formed would have been
unfilterable. At 150 g/l the substance is a free flowing liquid.
At higher concentrations gel formation was noted.
250 g/l Flowable viscous gel.
300 g/l Semi-solid gel.
350 g/l Gelatinous solid.
450g/l Gelatinous solid.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): very soluble (> 10000 mg/L)
The water solubility has been determined to be greater than 300 g/l of solution at 21.0 ±0.5 degC by the flask method based on Method A6 of Commission Directive 92/69/EEC. - Executive summary:
In a general physico-chemical properties study (525/026), the water solubility has been determined to be greater than 300 g/l of solution at 21.0 ±0.5 degC by the flask method based on Method A6 of Commission Directive 92/69/EEC.
