Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2009-11-12
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
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:
other: OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Type of method:
other: The cmc has been determined using the harmonised ring method
Water solubility:
73 mg/L
Temp.:
23 °C
pH:
7
Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 73 mg/L (pH 7, 23°C).

Additional information

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.
