Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): miscible
The water solubility of test substance was determined to be ≥ 66.7 wt%.
Executive summary:

The water solubility of the test substance was determined by stepwise addition of the test substance into water and visual inspection. An amount of 1, 2, 4, and 13 g of test substance was added into the same Erlenmeyer-flask containing 10g water in

each step. The total amounts of the test substance after each addition were 1, 3, 7, and 20 g. A clear, colorless solution was obtained after each addition. The water solubility of test substance was determined to be ≥ 66.7 wt%.

This study did not follow a guideline nor conducted under GLP. However, the test procedure meets generally accepted scientific principles and is acceptable for assessment.
