- other: expert assessment
- Parameter:
- other: Calculation of oxygen balance
- Remarks on result:
- other: Calculation of the oxygen balance is -118.69 for the main constituent.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on this evaluation, FAT 40034 is considered to be non-oxidising and therefore is not to be tested experimentally to fulfil the data requirements for Regulation 1907/2006/EEC (REACH) or for the classification under section 5.1 as oxidising substances (UN RTDG) or as an oxidising substance according to Regulation EC 1272/2008 (CLP).
- Executive summary:
In summary, analysis of the chemical structure reveals some alerts for oxidising properties. The calculated chemical oxygen balance is negative, indicating that the substance might not be capable of causing fire or enhancing the risk of fire when in contact with combustible materials.
Based on this evaluation, FAT 40034 is considered to be non-oxidising and therefore is not to be tested experimentally to fulfil the data requirements for Regulation 1907/2006/EEC (REACH) or for the classification under section 5.1 as oxidising substances (UN RTDG) or as an oxidising substance according to Regulation EC 1272/2008 (CLP).
Reference
Screening evaluation
No experimental test data according to EU Method A.17 (solids) and A.21 (liquids) or comparable methods for FAT 40034 are available.
Considering that oxidising properties are associated with the presence of certain chemical groups in the molecule, a screening evaluation can be conducted aimed to identify the presence of such reactive groups within the molecular structure harvesting the capability for a rapid high energy release.
Analysis of the above depicted molecular structure revealed, that no alert structures are present in the molecule. Only oxygen is present in form of sulfonate and phenyl-sulfone groups within the molecule.
Calculation of the oxygen balance according to the above-mentioned formula is -118.69 for main constituent and therefore indicates that there is a surplus of carbon in the molecule for a complete reaction according to the following reaction scheme:
Cx Hy Oz Sq + [x + (Y/4) - (z/2) + q]O2 → x[CO2] + q [SO2] + (y/2) [H2O]

Additional information
Justification for classification or non-classification
As Reactive Red 024:1contains no chemical groups present in the molecule which are associated with oxidising properties, it does not need to be classified as per the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
