Results and discussion
Water solubility
- Water solubility:
- >= 26.7 - <= 117.1 mg/L
- Temp.:
- 20 °C
- pH:
- >= 5 - <= 6
- Remarks on result:
- other: With increasing concentrations of the test substance, the dissolved amount of test substance is lower.
- Details on results:
- As solubility was dependant on nominal concentration, no exact value for the solubility of the test substance was stated. See table in 'Any other information on results incl. tables' for details on measured values.

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The water solubility of the test substance at 20°C was measured to be within the range 26.7 to 117.1 mg/L, applying the shake-flask method. The banding of slightly soluble (0.1 - 100 mg/L) was chosen as a worst case.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
