Applicant's summary and conclusion
- Conclusions:
- The pH value of the test item was determined to be 5.27.
- Executive summary:
An experimental study was conducted to determine the pH value of the test item according to CIPAC Method MT 75.3 and EPA OPPTS 830.7000. Therefore, a 1 %(v/v) aqueous solution of the test item was prepared. Two replicates were tested after 1 min and 10 min. The mean pH value of the test item solution after 10 min was determined to be 5.27.
