Oxidising properties
Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- other: Expert statement
- Adequacy of study:
- key study
- Study period:
- 23 September 2021
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Based on the expert statement and oxygen balance in the substance. 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.
- GLP compliance:
- no
- Parameter:
- other: The calculated chemical oxygen balance
- Remarks on result:
- other: 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 and is considered to be non-oxidising.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- 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 20306 is considered to be non-oxidising. - Executive 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 20306 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
No experimental test data according to EU Method A.17 (solids) and A.21 (liquids) or comparable methods for FAT 20306 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 -196.29 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
Description of key information
The test substance is considered to be non-oxidising.Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
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 20306 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).
Justification for classification or non-classification
As there are no chemical groups associated with oxidising properties present in the molecule of the substance, the substance is considered to be not oxidising and classification as an oxidising solid according to CLP (Regulation EC No 1272/2008) or DSD (Directive 67/548/EEC) is not required.
