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.
