Results

An examination of the structure of the test material reveals that it contains none of the reactive groups or oxidizing compounds known to increase oxidizing power. In addition the test material is an organic substance and does not contain oxygen, fluorine or chlorine atoms. As such, testing does not need to be carried out.

Interpretation of results:

other: no oxidising properties

Remarks:

Migrated information

Conclusions:

The lack of chemical groups associated with oxidising potential suggests that the test material is not likely to possess oxidising properties and no further testing is required.

Executive summary:

A structural examination of the test material was performed in order to assess the requirement for further testing of the oxidising potential of the compound, in accordance with the ‘Guidance on Information Requirements and Chemical Safety Assessment – Chapter R.7a: Endpoint Specific Guidance’.

Examination revealed that the test material contains none of the reactive groups or oxidizing compounds known to increase oxidizing power. In addition the test material is an organic substance and does not contain oxygen, fluorine or chlorine atoms. As such, it is not likely that the test material possesses oxidising properties and thus no further testing is required.

Description of key information

An expert report (Carling & Liney, 2012) based on a structural evaluation of the test material has been provided as the key study. The report concludes that the test material does not contain oxidising properties and thus further testing is not required.

Key value for chemical safety assessment

Oxidising properties:

no

Additional information

A structural examination of the test material was performed in order to assess the requirement for further testing of the oxidising potential of the compound, in accordance with the ‘Guidance on Information Requirements and Chemical Safety Assessment – Chapter R.7a: Endpoint Specific Guidance’.

Examination revealed that the test material contains none of the reactive groups or oxidizing compounds known to increase oxidizing power. In addition the test material is an organic substance and does not contain oxygen, fluorine or chlorine atoms. As such, it is not likely that the test material possesses oxidising properties and thus no further testing is required.

Justification for classification or non-classification

The structural evaluation indicates that the test material does not contain oxidising properties and therefore does not require classification under Regulation (EC) No. 1272/2008.
