Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Version / remarks:
- flask method
- Deviations:
- yes
- Remarks:
- two data points per sample instead of three; no substance specific analytical method.
- Principles of method if other than guideline:
- only two samples per concentration reported; no saturation point found; analytic determination with titration of acid is not substance specific
- GLP compliance:
- no
- Type of method:
- flask method
- Key result
- Water solubility:
- > 80 vol%
- Conc. based on:
- test mat. (total fraction)
- Loading of aqueous phase:
- 1 460 g/L
- Incubation duration:
- 24 h
- Temp.:
- 20 °C
- pH:
- < 0
- Remarks on result:
- completely miscible
- Remarks:
- clear solution obtained without any phase separation after 24h. Analytic tests from bottom and surface of sample show homogeneous solution
- Details on results:
- No obserrvation of phase separation at any of the nominal concentrations tested (20, 40, 60, 80 vol%).
- Conclusions:
- PFBS is full miscible with water. Water solubility at 20°C is >1000g/L
