Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 present any oxidising properties.
Data on constituents:
CeO2: No oxidising properties,
La2O3: No oxidising properties,
LaF3: No experimental data, but should not show any oxidising properties based on expert statement.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
A GLP-compliant study of reliability 1 according to Klimisch was available on the reaction mass (Demangel, 2010) revealing it has no oxidising properties. This data 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 oxidising properties.
All these data on the three constituents were thus selected as supporting studies.
Justification for classification or non-classification
Based on the above data, reaction mass of cerium dioxide and lanthanum oxide and lanthanum fluoride does not require a classification regarding its oxidising properties, neither under DSD, nor under CLP.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
