Applicant's summary and conclusion

Conclusions:
The pH determination of test item was done following OECD guideline 122. pH of 1% w/v emulsion was measured with the help of pH meter and it was observed to be 4.83 at 29 °C.
Executive summary:

The pH determination of test item was done as per the test guideline OECD 122. The mean pH of the test emulsion was determined with the help of digital pH meter. The mean pH was determine to be 4.83 at 29 °C. This value indicates that the substance is acidic in nature.
