Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Key result
Sample tested:
test mixture as specified
Remarks:
test substance/cellulose (ratio 5/95)
Parameter:
maximum burning rate
Result:
2 mm/s
Remarks on result:
other: Steady burning with flame throughout the whole mass
Sample tested:
test mixture as specified
Remarks:
test substance/cellulose (ratio 10/90)
Parameter:
maximum burning rate
Result:
1.9 mm/s
Remarks on result:
other: Steady burning with flame throughout the whole mass
Sample tested:
test mixture as specified
Remarks:
test substance/cellulose (ratio 20/80)
Parameter:
maximum burning rate
Result:
1.8 mm/s
Remarks on result:
other: Steady burning with flame throughout the whole mass

Max. burning rate of the reference mixture barium nitrate/cellulose 60:40 = 3.2 mm/s.


Max. burning rate: mixture with 5% of product = 2.0 mm/s.


Max. burning rate test mixture / Max. burning rate reference mixture = 2.0 mm/s / 3.2 mm/s = 0.63

Interpretation of results:
GHS criteria not met
Conclusions:
The maximum burning rate of the test substance (2.0 mm/s at 5 % test substance and 95 % cellulose) was lower than the maximum burning rate of the reference substance, barium nitrate/cellulose, (3.2 mm/s at 60:40). The product is therefore not considered an oxidising substance.
Executive summary:

The oxidising potential of the test substance was determined according to EC Test A.17 following GLP principles. The maximum burning rate of the test substance (2.0 mm/s at 5 % test substance and 95 % cellulose) was lower than the maximum burning rate of the reference substance, barium nitrate/cellulose, (3.2 mm/s at 60:40). The product is therefore not considered an oxidising substance.

Description of key information

Oxidising properties: The maximum burning rate of the test substance was lower than the maximum burning rate of the reference substance, barium nitrate/cellulose. The product is therefore not considered an oxidising substance. EC Test A.17, Schürch 1991.

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Justification for classification or non-classification

Based on the available information, classification on oxidising properties is not warranted in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. (EC) 1272/2008.
