Applicant's summary and conclusion

Conclusions:
The mean pH-value of "Grewe-diamin" in water (1 % w/v) is 10.65, 2 determinations.
Executive summary:

The pH-value of"Grewe-diamin"in water (1 % w/v) was determined by means of a pH meter (InoLab pH Level 2; WTW) and a glass electrode (SenTixMic; WTW).

The temperature during the test was 20.0 °C.

The results of the 2 repeat determinations of the pH value of the test substance were:
10.65 each.

The mean pH-value of"Grewe-diamin"in water (1 % w/v) is 10.65, 2 determinations.
