Executive summary:

A study was conducted to determine the oxidising properties of the test substance according to EU Method A.17, in compliance with GLP. Oxidising properties of test substance analysed with different test substance concentration (10%, 30%, 60% and 80%) in mixture with cellulose. The test results as follows 10% mixture burning rate was 2.2 mm/s, 30% mixture sample ignited and burned with flame which went off in 15 s and smoulder locally for 5 minutes and 60 and 80% mixtures samples ignited and smouldered locally for up to 5 minutes and did not propagate the combustion beyond the first timing mark and no burning times could be recorded. Under the study conditions, the test substance is not significantly enhancing the burning properties of cellulose so test substance is not an oxidiser (Jackson, 1994).

Description of key information

The oxidising properties were determined according to EU Method A.17 (Jackson, 1994).

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

Justification for classification or non-classification

Based on the results of the oxidising properties study, the substance does not warrant classification according to EU CLP (EC 1272/2008) criteria.
