Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Reaction mass of cerium dioxide and lanthanum oxide and lanthanum fluoride does not show any self-ignition up to 500°C.
Data on constituents:
CeO2: No self-ignition up to at least 400°C,
La2O3: No self-ignition up to at least 400°C,
LaF3: No experimental data, but should not show any potential for self-ignition based on expert statement.
Key value for chemical safety assessment
Additional information
A GLP-compliant study of reliability 1 according to Klimisch was available on the reaction mass (Demangel, 2010) and revealed the absence of self-ignition up to 500°C. It was flagged as a key study.
A similar conclusion was drawn from experimental data of reliability 2 (Cerutti, 2005a, b) on cerium dioxide and lanthanum oxide. For lanthanum fluoride, an expert statement was provided showing this substance should not show any potential for self-ignition.
All these data on the three constituents were thus selected as supporting studies.
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.
