Interpretation of results:
GHS criteria not met
Conclusions:
This substance tested has no oxidising properties.

Description of key information

In an EU method, GLP-compliant study, the substance did not ignite or burn during the test and therefore the test item does not have oxidising properties.

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

Justification for classification or non-classification

The test item did not ignite or burn during the test and therefore the substance has no oxidising properties. The substance is not classified as an oxidising solid in accordamce with the CLP regulation (EC 1272/2008).
