Constituent 1
Results and discussion
Water solubility
- Water solubility:
- ca. 2 mg/L
- Temp.:
- 20 °C
- Remarks on result:
- other: pH was not measured for this essay
- Details on results:
- This is one of the highest concentration observed though different measurements.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
Under the experimental conditions, the maximum water solubility of SEPISOL VIOLET 2B has been estimated to be 2 mg/L using optical density analysis. However this value is the highest observed by analysis.
