Applicant's summary and conclusion

Conclusions:
The pH of a 1% (w/v) aqueous mixture was determined to be 4.0
Executive summary:

In a GLP study according to CIPAC MT 75.3, OECD 122 and OPPTS 830.7000, the pH of the substance in double distilled water was determined. The pH values of two 1% (w/v) mixtures were measured obtaining a mean value of 4.0.
