Applicant's summary and conclusion

Conclusions:
Under the study conditions, the pH of the test substance was determined to be 6.5 at room temperature.
Executive summary:

A study was conducted to determine the pH of the test substance according to the German Industrial Standard DIN 48404 -C5. A concentration of 1.0 g/L test substance was dissolved and homogenized in distilled water. Under the study conditions, the pH of the test substance was determined to be 6.5 at room temperature (Schnalke, 1997).
