Description of key information

FAT 40827/A is considered to be non-oxidising.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

FAT 40827/A contains chlorine, fluorine and oxygen. Chlorine and fluorine are bonded to carbon only, whereas the oxygen atoms are bonded to sulphur. Thus, the conditions of the UN recommendations are not fulfilled and the oxygen balance was used as third criterion to predict oxidising properties: The oxygen balance of FAT 40827/A as calculated according to the UN recommendations and taking carbon, hydrogen and oxygen into consideration, was found to be negative. 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. Therefore, FAT 40827/A is considered to be non-oxidising and is not to be tested experimentally for the classification under division 5.1 as oxidising substances.

Justification for classification or non-classification

Based on expert assessment of the chemical structure the substance is not subject to classification for oxidising properties according to CLP (Regulation EC No 1272/2008) or DSD (Directive 67/548/EEC).
