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.
