Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7840 (Water Solubility)
- GLP compliance:
- yes
- Type of method:
- column elution method
- Key result
- Water solubility:
- ca. 0.007 mg/L
- Conc. based on:
- test mat.
- Loading of aqueous phase:
- 47.3 mg/L
- Incubation duration:
- ca. 16 h
- Temp.:
- 20 °C
- pH:
- >= 8 - <= 8.3
- Details on results:
- The water solubility of the test item at 20°C was 0.0067 mg/L. The value was estimated by extrapolation of the calibration curve and it was below the LOQ (established at 0.01 mg/L). The coefficient of variation of the measurement at both flow rates were within criteria. The pH values of the aqueous samples were between 8.0 and 8.3.
- Conclusions:
- The column elution method was applied for the determination of the water solubility of Disperse Blue 359.
The water solubility of the test item at 20°C was 0.0067 mg/L. The value was estimated by extrapolation of the calibration curve and it was below the LOQ (established at 0.01 mg/L). The coefficient of variation of the measurement at both flow rates were within criteria. The pH values of the aqueous samples were between 8.0 and 8.3.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
