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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
The reaction mass of cerium dioxide and zirconium dioxide is an inorganic substance described as a yellow powder. This conclusion is based on visual observation of a representative nanoform, but also holds for any potential bulk form, should such form be placed on the market.
Key value for chemical safety assessment

- solid
- Form:
- solid: particulate/powder
- Colour:
- yellow
Additional information
Two GLP-compliant studies (Demangel, 2010a,b), intended to assess other physicochemical endpoints, provide a description of the test item (nanoform). Both studies were performed on the same substance sample. Therefore, they were reported in one endpoint study record which was flagged as a key study.
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.
