Applicant's summary and conclusion
- Conclusions:
- pH values of various concentrations of the test item in water were determined using a pH measuring instrument, the study is suffiiently documented to conclude that the study was well performed. pH values increase 5.5 to 6.0 with increasing substance concentrations, i.e. 1% to 50%.
- Executive summary:
pH values of aqueous solutions of Bis(2,4,6-triisopropylphenyl)carbodiimide were determined to 5.5 (1 weight%), 5.7 (10 weight %) and 6.0 (50% weight %).
