- other: Not applicable
- Vehicle:
- not specified
- Details on study design:
- Preparation of test item:
At first, a 10% solution of the test item was prepared by stirring 10 g sample material with 90g H2O dem. (Milli-Q water - Type 1 water grade) for 30 minutes and then adjusting it to a temperature of 20°C.
Calibration of the pH-meter:
Prior to the measurement the pH meter was checked and calibrated with a buffer solution in the expected measurement range. The pH meter was calibrated via a 3-point calibration. The slope of the electrode and the result of the control buffer were either listed in the "Prüfmittelkontrollblatt" or "calibration report". The electrode was rinsed with H2O dem., wiped dry and immersed for measurement into the solution.
Determination of the pH-value of the test item:
The pH is determined 3 times from a 10% solution of the test item under continuous stirring. The measured pH was protocolled.
Apparatus and auxiliary material:
- Analytical scales with an accuracy of 0.01g
- pH-meter with pH electrode or 809 Titrando v. Metrohm
- Buffer solutions 1.09, 4.01, 6.00
- Magnetic stirrer with magnetic stir bar
- Beakers
- Flask
- Water bath
- Pipettes
- Milli-Q water

Results
- Remarks on result:
- other: The substance is considered not to be corrosive
- Irritant / corrosive response data:
- Not corrosive
Any other information on results incl. tables
Since the determined pH-value was 4.58 a determination of the acid reserve was not applicable.
Applicant's summary and conclusion
- Interpretation of results:
- other: not corrosive
- Conclusions:
- The pH value was determined to be 4.58. Because of this pH value a determination of the acid reserve was not applicable.
