STRUCTURAL ASSESSMENT

An examination of the structure of the test material reveals that it contains an electronegative atom (O), but this is bonded only to carbon and hydrogen, and therefore, is unlikely to add to the oxidising power. The structural examination of the test material suggests it is not likely to possess oxidising properties.

Interpretation of results:
other: Not likely to possess oxidising properties
Conclusions:
The structural examination of the test material suggests it is not likely to possess oxidising properties.
Executive summary:

A substance which possesses oxidising properties is capable of reacting exothermically with a combustible material. An assessment of the structure gives an indication of the likelihood of the substance possessing oxidising properties.

A substance may not have oxidising properties when: the substance or mixture does not contain oxygen, fluorine or chlorine or when the substance or mixture contains oxygen, fluorine or chlorine and these elements are chemically bonded only to carbon or hydrogen.

An examination of the structure of the test material reveals that it contains an electronegative atom (O), but this is bonded only to carbon and hydrogen, and therefore, is unlikely to add to the oxidising power. The structural examination of the test material suggests it is not likely to possess oxidising properties.

Description of key information

In accordance with Section 7.13 of Column 2 of Annex VII of the REACH Regulation, it is considered justified to omit the testing for oxidising properties on the grounds that the substance is incapable of reacting exothermically with combustible materials. From the compositional description and the structural formula of the substance, there are no functional groups present that would indicate that this substance would promote oxidation and thus should not be classified as dangerous according to the criteria for evaluating oxidising properties. This is supported by long term experience in the handling and use of the substance.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

Justification for classification or non-classification

From long term experience in the handling and use of the substance, the compositional description and the structural formula of the major components of the substance, it can be concluded that the substance is unlikely to exhibit oxidising properties. There are no functional groups present that would indicate that this substance would promote oxidation and thus should not be classified as dangerous according to the criteria for evaluating oxidising properties.
