- Endpoint:
- oxidising solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied
- other:
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
Experimental results have been determined for Bayferrox 303 T (Manganese ferrite) which has a very similar composition as Bayferrox 645T (iron manganese trioxide). According to the product information leaflet, the compositions of the Bayferrox types in discussion are:
Compound Bayferrox 303 T Bayferrox 645 T
Fe2O3 73 % 85 %
SiO2 + Al2O3 < 5 % < 4 %
MnO < 22 % < 10 %
The SiO2 and Al2O3 are very stable compounds they will not react even at high temperatures neither with flammable material nor with air and should be considered inert with respect to the physical properties relevant for classification. - Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
Description of key information
Since iron manganese trioxide is a mixed oxide of MnO 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 DR Lide, CRC Handbook of Chemistry and Physics, 88th edition, 2007-2008), the oxidation potentials of Fe3+ and Mn2+ ions are low. This statement is in line with the experimental findings for manganese ferrite (CAS 68186-94-7).
Iron manganese trioxide has no oxidising properties according to UN Test Procedure O.1 (34.4.1).
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.
