- Version / remarks:
- According to CLP Regulation EC 1272/2008 Section 2.14.4.1, for organic substances or mixtures the classification procedure shall not apply if:
(a) the substance or mixture does not contain oxygen, fluorine or chlorine; or
(b) the substance or mixture contains oxygen, fluorine or chlorine and these elements are chemically bonded only to carbon or hydrogen.
For inorganic substances or mixtures, the classification procedure for this class shall not apply if they do not contain oxygen or halogen atoms. - Deviations:
- not applicable
- Principles of method if other than guideline:
- According to CLP Regulation EC 1272/2008 Section 2.14.4.1, for organic substances or mixtures the classification procedure shall not apply if:
(a) the substance or mixture does not contain oxygen, fluorine or chlorine; or
(b) the substance or mixture contains oxygen, fluorine or chlorine and these elements are chemically bonded only to carbon or hydrogen.
For inorganic substances or mixtures, the classification procedure for this class shall not apply if they do not contain oxygen or halogen atoms. - GLP compliance:
- no
- Sample tested:
- other: Oxygen balance
- Parameter:
- other: based on calculated chemical oxygen balance
- Remarks on result:
- other: See remarks
- Remarks:
- 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.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- FAT 40879 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 40879 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
Analysis of the above depicted molecular structure revealed, that chlorine and oxygen are present in the molecule.
While chlorine is strictly bound to carbon atoms, oxygen is also present in form of sulfonate and vinyl sulfone groups within the molecule.
Calculation of the oxygen balance according to the above-mentioned formula is -113.78 for main constituent 1 and
-108.58 for main constituent 2 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) = x CO2 + q SO2 = xCO2+q SO2+ (y/2)H2O
Description of key information
FAT 40879 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 40879 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
The test substance has been considered to be non-oxidising based on the expert statement, hence does not warrant classification according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 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).
