Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L)
As the measured concentrations correspond to the total dissolution of the test substance, the water solubility of Reactive Red F08-0146 is higher than 399 g/l at 20°C.
Executive summary:

The water solubility of Reactive Red F08-0146 is higher than 399 g/L at 20°C.

Reactive Red F08-0146 is considered to be very soluble in water.
