Applicant's summary and conclusion
- Conclusions:
- The substance reacts acidic in a 30% aqueous solution with a pH <2.
- Executive summary:
The pH values of the aqueous solution of the dissolved solid remain stable for at least one week (within the measurement inaccuracy). They are each below 2.0, based on the 30% solution.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
