Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Version / remarks:
- A.6 (modif.flask method)
- Deviations:
- yes
- Remarks:
- The solution obtained from dissolving the test substance in water showed a high viscosity. Therefore it was decided to perform the experiments with amounts lower than required by the guideline.
- GLP compliance:
- yes
- Type of method:
- flask method
Test material
- Details on test material:
- - Name of test material (as cited in study report): Reaktiv-Orange DYPR934
Constituent 1
Results and discussion
Water solubility
- Water solubility:
- 527.29 g/L
- Temp.:
- 20 °C
- pH:
- ca. 4.6
- Details on results:
- Final result:
Average: 527.29 g/L
Standard deviation: 70.70 g/g
Relative standard deviation: 13 %
Final result:
295 g/L (RSD: 13 %) = 295000 mg/L (corrected for the purity of 56 %) at 20 °C
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): very soluble (> 10000 mg/L)
The final result reveals a water solubility of 295000 mg/L (corrected for the purity of 56 %) at 20 °C. This value is > 10000 mg/L; therefore, the water test substance is considered to be very soluble. - Executive summary:
The final result reveals a water solubility of 295000 mg/L (corrected for the purity of 56 %) at 20 °C. This value is > 10.000 mg/L; therefore, the water test substance is considered to be very soluble.
Average: 527.29 g/L
Standard deviation: 70.70 g/g
Relative standard deviation: 13 %
Final result:
295 g/l (RSD: 13 %) = 295000 mg/L(corrected for the purity of 56 %) at 20 °C
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
