Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2009-10-19
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
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 is determined according to standardized method, no GLP compliance
Qualifier:
according to guideline
Guideline:
other: OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
yes
Remarks:
pH is adjusted to 7
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. The cmc has been determined using the harmonised ring method
GLP compliance:
no
Type of method:
other: The cmc has been determined using the harmonised ring method
Water solubility:
5 mg/L
Temp.:
22 °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 5 mg/L (pH 7, 22°C).
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 5 mg/L (pH 7, 22°C).
Executive summary:

Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 5 mg/L (pH 7, 22°C).

Description of key information

The water solubility is 5 mg/L (pH 7, 22°C).

Key value for chemical safety assessment

Water solubility:
5 mg/L
at the temperature of:
22 °C

Additional information

Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 5 mg/L (pH 7, 22°C).
