Oxidising properties

Link to relevant study record(s)

Reference

Endpoint:

oxidising solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied

Description of key information

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

Key value for chemical safety assessment

Oxidising properties:

non oxidising

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)..
