Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2011 -09-20
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Remarks:
The CMC is determined according to standardized method. (According to "Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance", the critical micelle concentration (CMC) can be view as the solubility limit.)
Qualifier:
according to guideline
Guideline:
other: OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
GLP compliance:
no
Type of method:
other: The cmc has been determined using the harminised ring method
Water solubility:
149 mg/L
Temp.:
23 °C
pH:
7
Details on results:
Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 149 mg/L (pH 7, 23°C).
Conclusions:
Interpretation of results (migrated information): moderately soluble (100-1000 mg/L)
Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 149 mg/L (pH 7, 23°C).
Executive summary:

The substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 149 mg/L (pH 7, 23°C).

The CMC is determined according to standardized method. (According to "Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance", the critical micelle concentration (CMC) can be view as the solubility limit.)
