Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint summary
Administrative data
Description of key information
No data are put forward as this endpoint is not relevant for cerium, and metals in general.
Additional information
The endpoints "Phototransformation of an element in water, soil or air" and 'Hydrolysis" are not relevant for substances that are assessed on an elemental basis, i.e., based on the exposure and effects of cerium, expressed as elemental Ce.
For cerium substances, the chemical safety assessment is based on elemental metal concentration, i.e., the assessment of cerium is conducted regardless of the (pH-dependent) speciation in the environment. Hence, as the assessment is based on the element concentration (i.e., Ce), physicochemical processes like decomposition and degradation by reaction with water are not relevant. This elemental-based assessment (pooling together of all speciation forms) can be considered as a worst-case assumption for the chemical assessment.
In general, (abiotic) degradation is an irrelevant process for inorganic substances that are assessed on an elemental basis.
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.
