Description of key information
In accordance with section 1 of REACH Annex XI, the study does not need to be conducted. This substance is a mixed oxide of ZnO and Fe2O3, which will not react exothermally with flammable substances due to its chemical structure. According to the tables for potentials of electrochemical reactions (see CRC Handbook of Chemistry and Physics), the Zn2+ ion has a strongly reducing character. The oxidation potential of the Fe3+ ion is considerably lower than the potential of the reference substances used in UN method O.1 or EC method A17. Therefore, this compound does not have any oxidizing properties.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
Justification for classification or non-classification
The substance has no oxidising properties; and hence no classification according to both Directive 67/548/EEC and GHS (Regulation EC 1272/2008).
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.
