Applicant's summary and conclusion

Executive summary:

The determination of the pH-value was performed according to CIPAC MT 75.3. The determination of the pH value was performed with a pH meter equipped with a calibrated single-rod glass electrode. The pH-value was determined of the undiluted Bayhibit AM and of a 1 % solution of the test item in demineralised water. The following results were received:

pH-value (1%): 1.9

pH-value (undiluted): 0.0
