Dissociation constant
Administrative data
- Endpoint:
- dissociation constant
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance has no ionic structure
- the study does not need to be conducted because the substance is insoluble

Applicant's summary and conclusion
- Conclusions:
- In accordance with section 1 of REACH Annex XI, the dissociation constant study specified under information requirement 7.16 of Annex IX does not need to be conducted as it is not scientifically relevant. Section R.7.1.17.1 of Chapter R.7a: Endpoint specific guidance states that the dissociation constant endpoint is not intended to cover the dissolution of salts from their crystal lattice into individual ions. As the substance is a mixed metal oxide salt, it is therefore considered that that the dissociation constant study is not required.
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.
