Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Contact with:
- powdered cellulose
- Duration of test (contact time):
- >= 234 - <= 370 s
- Sample tested:
- test mixture (not specified)
- Parameter:
- maximum burning rate
- Result:
- 0.87 mm/s
- Remarks on result:
- other: The mixture contained 10% test substance
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The maximum burning rate of the test substance has been found to be less than that for barium nitrate, and the test substance does not therefore possess oxidising properties.
- Executive summary:
The oxidising properties of the test substance were determined in accordance woth EEC Directive 67/548, Annex V, A17 as published in 84/449/EEC. The test method determined whether a substance has oxidising properties compared to a reference substance, barium nitrate. A substance is considered as possessing oxidising properties when the maximum burning rate of the test mixtures is higher than, or equal to, the maximum burning rate of the reference mixtures. Oxidiser/cellulose mixtures containing 10 -90% by weight of oxidiser were prepared. The test was repeated a further 5 times for each of the 3 fastest burning test substance mixtures, the 10, 20, and 30% concentrations. The mixture containing 60% barium nitrate burned faster than any of the others. The maximum burning rate of the test substance was less than that for barium nitrate, so the test substance does not possess oxidising properties.
Reference
The maximum burning rate of the reference mixture was 1.42 mm/s for a mixture containing 60% barium nitrate.

Additional information
Justification for classification or non-classification
The test substance is not considered an oxidiser and is not classified according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC)
No. 1272/2008.
