Applicant's summary and conclusion
- Conclusions:
- Under the conditions of the study the pH of a 1 % w/v suspension of the test material was found to be 2.9.
- Executive summary:
The pH of the test material was assessed according to EPA OPPTS Guideline 830.7000 and CIPAC MT 75.2 and in compliance with GLP.
The pH electrode was calibrated using pH 4.0 and pH 10.0 buffer solutions. The calibration was then checked by measurement of the pH 7.0 buffer solution. The procedure was conducted in duplicate.
Under the conditions of the study the pH of a 1 % w/v suspension of the test material was found to be 2.9.
