Key value for chemical safety assessment

Oxidising properties:
no

Additional information

The test item FAT 40849/A TE has been evaluated in accordance with the criteria given in the UN Recommendations on the Transport of Dangerous Goods. Further evaluation has been done by detailing the molecule in small subunits for which a classification with regard to oxidizing properties already exists. The subunits are: sodium benzenesulfonate and phenyl vinyl sulfone. Those substances are not classified to be oxidising. Additionally, it can be stated that the oxygen balance of FAT 40849/A TE is negative as calculated based on the UN Recommendations on the Transport of Dangerous Goods. In principle this means, that there is a surplus of carbon atoms for a complete reaction according to the following reaction scheme:    

CxHyOz + [x + (y/4) – (z/2)] · O2 → x · CO2 + (y/2) · H2O, where CxHyOzis the test item.  

Applying the internationally recognised UN Recommendation criteria and further criteria as published in several official documents, FAT 40849/A TE is found to be non oxidising and therefore is not to be tested experimentally for the classification under division 5.1 as oxidising substances. Thus it can be concluded beyond a reasonable doubt that FAT 40849/A TE is not capable of causing fire or enhancing the risk of fire when in contact with combustible material.

Justification for classification or non-classification

On the basis of criteria for oxidising properties given in the UN Recommendations on the Transport of Dangerous Goods and further criteria published in other official documents, the substance FAT 40849/A TE is considered as non oxidising. A classification for oxidising properties hence is not required.
