Results and discussion
pH value
- pH value:
- 9.91
- Temp.:
- 24.9 °C
- Concentration:
- 10 g/L
- Remarks on result:
- other: suspension
Any other information on results incl. tables
As the water solubility of test item is less than 1 w/v % (10 g/L) so a suspension was resulted.
After stirring the solid particles were allowed to settle for 5 minutes. The pH was measured from the supernatant of the suspension.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
