Applicant's summary and conclusion

Conclusions:
The water solubility was determined to be 311 g/L at 20°C.
Executive summary:

The water solubility of acylglycinate GCK-12H -T (dry matter) was investigated in a study conducted according EU Method A.6 (Water Solubility) and OECD Guideline 105 (Water Solubility) and using the flask-method. The water solubility determined via HPLC measurements was found to be 311 g/L at 20°C. The recovery experiments with standard solutions indicated a sufficient accuracy of the analytical method.
