Interpretation of results:
GHS criteria not met
Conclusions:
Under the study conditions, the test substance was determined to be not oxidising.
Executive summary:

A study was conducted to determine the oxidising properties of the substance according to EU Method A.17. A reduced testing programme was employed because of the very slow or complete lack of combustion observed in the test at 10, 30, 60 and 80% mixtures.The test substance attenuated the burning of cellulose rather than enhancing it. Under the study conditions, the test substance was determined to be not oxidising (Pittam, 1987).

Description of key information

The oxidising properties were determined according to EU Method A.17 (Pittam, 1987).

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

Justification for classification or non-classification

Based on the results of an oxidisation study, the substance does not require classification for this endpoint according to CLP (EC 1272/2008) criteria.
