Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- August 17, 2011 - January 10, 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- flask method
- Key result
- Water solubility:
- > 1 000 g/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- Remarks on result:
- other: The pH of water mixture could not be determined due to the high viscosity of the sample.
- Details on results:
- After the stirring period, the solution was clear and no undissolved test substance was observed. From this, it was concluded that the water solubility of the test substance at 20°C was > 1 kg/L.
- Conclusions:
- Interpretation of results: Very soluble (> 10000 mg/L)
The water solubility of the substance at 20°C is > 1 kg/L, determined in accordance with OECD 105, EU Method A.6 and GLP
Reference
Description of key information

The critical micelle concentration of the substance was determined to be 717.54 mg solids/L.
Key value for chemical safety assessment
- Water solubility:
- 1 000 g/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of the substance at 20°C is > 1 kg/L, determined in accordance with OECD 105, EU Method A.6 and GLP.
The critical micelle concentration of the substance was determined to be 717.54 mg solids/L. The critical micelle concentration (CMC) of the substance was determined by measuring the surface tension of solutions at seven different substance concentrations according to a method based on ISO 4311. As the substance contains a high percentage of water a correction factor was applied and the concentrations were expressed as mg solid/L. The surface tension measurements were performed according to the OECD harmonized ring method (EC A.5 and OECD 115).
