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 EC A.21 and UN Test O.2, it was determined that the substance has no oxidizing properties. The 1:1 (by mass) mixture of the substance and cellulose was observed to have a mean pressure rise time greater than that of a 1:1 (by mass) mixture of 65% nitric acid and cellulose. Mean pressure time for the test substance mixture was 23.734 s. Mean pressure time for the reference mixture was 3.699 s.
