Applicant's summary and conclusion
- Conclusions:
- The pH determination of test chemical was done as per the test guideline OECD 122. The mean pH of the 1% w/v test dispersion was determined with the help of digital pH meter. The mean pH was determined to be 7.17 at 25.4°C.
- Executive summary:
The pH of test chemical was determined. The study was performed in accordance with OECD Guideline 122 (Determination of pH, Acidity and Alkalinity). The mean pH of the 1% w/v test dispersion was determined with the help of digital pH meter. The mean pH was determined to be 7.17 at 25.4°C, indicating that the test chemical is neutral.
