Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- Qualifier:
- according to guideline
- Guideline:
- other: lSO-standard n°304- 1985
- GLP compliance:
- not specified
- Type of method:
- other: tensiometry
- Key result
- Water solubility:
- 2.991 g/L
- Temp.:
- 20 °C
- Remarks on result:
- other: pH value was not determined
- Details on results:
- CMC (water solubility) at 20°C in water: 2.991 +/- 0.446 g/L
- Conclusions:
- As the test item is a surfactant, the critical micelle concentration (CMC) is considered as a solubility limit in water; the CMC (water solubilty) at 20 °C in is 2.991 g/L.
- Executive summary:
According to the Guidance on information requirements and chemical safety assessment, chapter R.7a, pp 77 and 107, it is prudent to take the critical micelle concentration (CMC) as a solubility limit. Water solubility is measured by tensiometry, a classical method to determine the CMC of a surfactant.
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 2012-2013
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Principles of method if other than guideline:
- estimation of water solubility of water soluble part of test item by DOC
- GLP compliance:
- no
- Type of method:
- other: DOC
- Key result
- Water solubility:
- > 170 mg/L
- Temp.:
- 23 °C
- Remarks on result:
- other: reconstituted water according to ISO 6431-1982
- Key result
- Water solubility:
- > 580 mg/L
- Temp.:
- 23 °C
- Remarks on result:
- other: Milli-Q water
- Conclusions:
- The water soluble fraction of the test item is moderately soluble in Milli-Q water (> 580mg/L at 23 °C) and also moderatly soluble in reconstituted water as used for aquatic tox testing (> 170 mg/L at 23 °C).

Description of key information
CMC (water solubility): 2.991 g/L at 20°C
DOC-water solublity: > 170 mg/L at 23°C
Key value for chemical safety assessment
- Water solubility:
- 2.991 g/L
- at the temperature of:
- 20 °C
Additional information
As the test item is a surfactant, the critical micelle concentration (CMC) is considered as a solubility limit in water of the test item. HPLC-spectra from diluted samples differ from the spectra of the pure sample, indicating that some part of UVCB may be insoluble. The max dissolved DOC content has been determined as > 170 mg/L at 23 °C in reconstituted water
