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:
OECD Guideline 105 (Water Solubility)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.6 (Water Solubility)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Type of method:
flask method
Key result
Water solubility:
> 1 000 g/L
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.

Description of key information

The water solubility of the substance at 20°C is > 1 kg/L, 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).
