Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2009
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
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. The CMC has been determined according to standardized method, no GLP compliance.
Qualifier:
according to guideline
Guideline:
other: OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
Principles of method if other than guideline:
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.
GLP compliance:
no
Type of method:
other: The cmc has been determined using the harmonised ring method
Key result
Water solubility:
>= 1 300 mg/L
Temp.:
23
pH:
7
Remarks on result:
other: NB: temperature range bewteen 23-25°C
Details on results:
Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC). For this substance the CMC has been determined to be between 1300 – 2200 mg/L (pH 7, 23 – 25°C). As a worst case, the water solubility will be reported as 1300 mg/L
Conclusions:
Interpretation of results (migrated information): soluble (1000-10000 mg/L)
Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC). For this substance the CMC has been determined to be between 1300 – 2200 mg/L (pH 7, 23 – 25°C). As a worst case, the water solubility will be reported as 1300 mg/L
