Individual results
The pH-value is recorded after 1 minute and after 2 minutes, without stirring of the solution during the measurement. If the pH-values differ by more than 0.1 pH units between first and second recording, the pH-value is also recorded after 10 minutes.
pH at 20 °C:
1. Measurement after 1 minute: 6.83
2. Measurement after 2 minutes: 6.92
3. Measurement after 10 minutes: 6.95
Applicant's summary and conclusion
- Conclusions:
- pH-value at 20 °C of the test substance was found to be 6.95
- Executive summary:
A study was conducted according to OECD test guideline 122 to determine pH of FAT 41047/A . The pH of an aqueous solution or dispersion in water is determined with a pH meter equipped with an appropriate electrode system. The test was performed at 20 °C
Buffer solutions used were pH1 = 4 and pH2= 7
The pH-value is recorded after 1 minute and after 2 minutes, without stirring of the solution during the measurement. If the pH-values differ by more than 0.1 pH units between first and second recording, the pH-value is also recorded after 10 minutes.
Based on findings of the study, the pH-value at 20 °C of the test substance was found to be 6.95.
