Results and discussion
Water solubility
- Water solubility:
- >= 405 g/L
- Temp.:
- 20 °C
- pH:
- 7.1
- Details on results:
- In Preliminary test 2, a mixture at a nominal concentration of 405 g/l was analysed after centrifugation. Concentration measured after two centrifugation steps was 439 g/l. From this it was concluded that all E-Y110 had dissolved and the water solubility is ≥ 405 g/l . The pH of the aqueous sample after two centrifugation steps was 7.1.
No further testing was performed because Preliminary test 1 (nominal end concentration 515 g/l) showed that no aqueous phase required for measurement of water solubility was obtained at higher concentration.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): very soluble (> 10000 mg/L)
Water solubility of E-Y110 at 20°C is ≥ 405 g/l. The pH of the aqueous sample after two centrifugation steps was 7.1.
