Results and discussion
Water solubility
- Key result
- Water solubility:
- 0.65 mg/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- pH:
- >= 6.3 - <= 6.4
- Details on results:
- At test end the pH values of the solutions in ultrapure water were pH 6.3, pH 6.4 on two independent flasks.
Applicant's summary and conclusion
- Conclusions:
- The test shows that there is no significant change of the measured concentrations after 288 h, 312 h and 336 h. Thus it can be concluded that equilibrium is reached. Thus the results obtained after 288 h, 312 h and 336 h were averaged, to give the water solubility of Velvione. After rounding off: Solubility of Velvione in water at 20°C: 0.65 mg/l
- Executive summary:
The solubility of Velvione in ultrapure water was determined according to the OECD Guideline No. 105 (flask method).
The result is: Solubility in water: 0.65 mg/l at 20°C
This result corresponds to the saturation mass concentrations of Velvione in ultrapure water at 20°C.
