Applicant's summary and conclusion

Conclusions:
The pH determination of test item 2-benzylideneheptanal (CAS No 122-40-7) 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 4.53at 26.8 °C.
Executive summary:

The pH determination of test item 2 -benzylideneheptanal (CAS No. 122 -40 -7 ) was done as per the test guideline OECD 122. The mean pH of the test emulsionwas determined with the help of digital pH meter. The mean pH was observed to be 4.53 at 26.8 °C.
