Applicant's summary and conclusion
- Interpretation of results:
- other: not classified under CLP/GHS
- Conclusions:
- The substance has no oxidizing properties.
- Executive summary:
In a GLP study according to UN Test O.1, it was determined that the substance has no oxidizing properties.
It should therefore be classed as a 'Not Division 5.1' substance according to the UN Recommendations.
