Conclusions:
According to OECD 105 and EU Method A.6, the water solubility of Everzol SR98 at 20.0 ± 0.5°C was 444 g/l.
Executive summary:

This test using the procedures outlined in the EVERLIGHT Study Plan for 191014-01, OECD 105 and EU Method A.6. The flask method was chosen for the determination of the water solubility ofEverzol SR98.In Main study, the maximum difference (MD) of the concentrations determined in the 24, 48 and 72 hour test sample was < 15%. The pH of the aqueous sample was 6.0.Therefore, the water solubility of Everzol SR98 at 20.0± 0.5°Cwas 444 g/l.

Description of key information

The water solubility of Everzol SR98 at 20.0± 0.5°C was 444 g/l (OECD TG105 and EU Method A.6).
