Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L)
After the stirring period, the test sample was clear and no undissolved test substance was observed. From this, it was concluded that the water solubility of Polyglycerol-3 at 20°C was > 1000 g/l. The pH of the aqueous sample was 7.2.
