Applicant's summary and conclusion

Conclusions:
The results in Table 1 and curves in Appendix 1 show that there is no significant change of the measured concentrations after 120 h, 144 h, 168 h and 192 h. Thus it can be concluded that equilibrium is reached. Thus the results obtained after 120 h, 144 h, 168 h and 192 h were averaged, to give the water solubility of Amberketal. After rounding off:
 Solubility of Amberketal in water at 20°C:0.63 mg/l
Executive summary:

The solubility of Amberketal in ultrapure water was determined according to the OECD Guideline No. 105 (flask method).

The result is:solubility in water: 0.63 mg/l at 20°C

This result corresponds to the saturation mass concentrations of Amberketal in ultrapure water at 20°C.
