Applicant's summary and conclusion
- Conclusions:
- The pH of test substance is 10.48 at 22.5 deg C .
- Executive summary:
The result of three observations was averaged to determine pH value for 1% aqueous solution/dispersion/emulsion depending on the solubility of test chemical.
Based on available data, experimental pH value for 1% aqueous solution of test substance was observed to be 10.48 at 22.2 °C ,inferring its basic nature.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
