Results and discussion
- Results:
- Memo: A wide range of stability constants for the association of the substance with metal ions is available. These all show high values, suggesting that in the environment the substance will be associated with ions such as calcium and magnesium.

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.
