Conclusions:
In the definitive test the determined result for water solubility of the test substance was an average value for the three time points 24, 48 and 72 hours. The average result was calculated to be 9.3 g/L.
The pH value of the test solution at the different time points was measured to be 6. The temperature during the test varied between 24.4 and 25.0°C.
Executive summary:

The water solubility of cyclohexanone peroxide was determined at a temperature of 25°C and based on OECD guideline 105. The data on water solubility represent the saturation mass concentration of the test substance in water.

The determined final result for water solubility of the test substance was calculated to be 9.3 g/L.
