Results and discussion

pH value
pH value:
5.3
Temp.:
24.8 °C
Concentration:
1 vol%

Any other information on results incl. tables

The pH of 1% test article was 5.29 at 24.76°C. The PDM indicates that acetic acid was removed from the reaction. Thus the slightly acidic pH would be consistent with small amounts of acetic acid not completely removed.

Applicant's summary and conclusion

Conclusions:
A pH of 5.3 at 24.76°C was determined for the substance in accordance with an appropriate test method and in compliance with GLP. The result is considered reliable.
