Applicant's summary and conclusion

Conclusions:
The water solubility of calcium potassium styphnat was determined to be 7.44 g/L at 20°C.
Executive summary:

The water solubility of calcium potassium styphnat was investigated in a study conducted according to OECD Guideline 105. In preliminary tests, the stability of the test item during the test duration was confirmed and the water solubility estimated to be 1 -10 g/L at 20°C. In the main test, the water solubility was determined to be 7.44 g/L at 20°C (average of 3 measurements).
