The maximum difference (MD) of the concentrations determined in the 24, 48 and 72 hour test samples was ≤ 15%. Based on this, the water solubility of the test substance is given as the mean value of the analysed concentrations.

A small response at the retention time was observed in the blank water mixture. The content was maximum 0.0014% to the water solubility of the test substance. It was considered that the response had no significant effect on the outcome of the test.

 

Conclusion

The water solubility of the test substance at 20 °C was 0.572 g/L.

The pH of the aqueous samples was 6.4-6.9.

Applicant's summary and conclusion

Conclusions:
