Applicant's summary and conclusion

Conclusions:
Corresponding to the analyses the water solubility of oxaceprol was determined to be 381 g/L at 20 °C.
The substance is highly soluble in water.
Executive summary:

The purpose of this guideline study was to evaluate the solubility of the test item in water which is specified by the saturation mass concentration of oxaceprol in water at a specified temperature.

The water solubility was determined using the shake flask method. The results showed no tendency to increase, therefore the study is considered to be valid.

Corresponding to the analyses the water solubility was determined to be 381 g/L at 20 °C.
