Interpretation of results:
GHS criteria not met
Conclusions:
The test item was found to have no oxidising properties.
Executive summary:

Younis (2018) is a GLP compliant study following EU method A.17 (Oxidising properties (Solids)) and is considered to be reliable without restrictions (Klimisch 1). As the test item did not ignite it is not an oxidising solid.

Description of key information

The test item was found to have no oxidising properties.

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

Younis (2018) is a GLP compliant study following EU method A.17 (Oxidising properties (Solids)) and is considered to be reliable without restrictions (Klimisch 1). As the test item did not ignite it is not an oxidising solid.

Justification for classification or non-classification

Based on the results of a study following a standard test guideline the substance is not classified as an oxidising solid.
