Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L)
The test compound stabilized EMIM BF4 is miscible with water in any ratio
Executive summary:

The solubility of stabilized EMIM BF4has been determined by following the OECD guideline 105. In a preliminary test, a solubility range of 200 – 1000 g/L has been identified. Under standard conditions at 30°C and a testing period of three days, stabilized EMIM BF4 is highly soluble in water (988 g/L). The pH value of the aqueous phase is slightly decreasing. Decomposition of the crowd material has not been observed.
