Oxidising properties
Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- November 07, 2011 - November 15, 2011
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- Deviations:
- no
- GLP compliance:
- no
- Contact with:
- powdered cellulose
- Key result
- Sample tested:
- other: test item and cellulose 2:1
- Parameter:
- maximum burning rate
- Remarks on result:
- mixture does not ignite and burn
- Remarks:
- All three test mixtures with the test item and cellulose 2:1 could not be ignited; neither burning nor glowing could be observed.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item has no oxidizing properties.
- Executive summary:
A study according to Regulation (EC) No 440/2008 method A.17 was performed to determine the oxidizing properties of the test item. Three mixtures of the test item and cellulose 2:1 were treated with a flame as ignition source for two minutes. All three test mixtures with the test item and cellulose 2:1 could not be ignited; neither burning nor glowing could be observed. Three test mixtures with barium nitrate/cellulose 2:1 burned down completely in 68 s, 70 s and 69 s, respectively.
Due to the results of the preliminary test (no burning or glowing of the mixtures containing the test item at all) and the high water content of the test item (80.5 %) the full test was waived. This conclusion is not valid, if the water content of the test item is lowered. Drying however was waived as the test item would chemically change during the process (loss of water and contact to air).
Due to the fact that the mixtures with test item and cellulose did not exhibit any burning or glowing it can be concluded that the test item has no oxidizing properties.
Reference
Preliminary test:
Three mixtures of the test item and cellulose 2:1 were treated with a flame as ignition source for two minutes. All three test mixtures with the test item and cellulose 2:1 could not be ignited; neither burning nor glowing could be observed.
Three test mixtures with barium nitrate/cellulose 2:1 burned down completely in 68 s, 70 s and 69 s, respectively.
Due to the results of the preliminary test (no burning or glowing of the mixtures containing the test item at all) and the high water content of the test item (80.5 %) the full test was waived. This conclusion is not valid, if the water content of the test item is lowered. Drying however was waived as the test item would chemically change during the process according to sponsor information (loss of water and contact to air).
Due to the fact that the mixtures with test item and cellulose did not exhibit any burning or glowing it can be concluded that the test item has no oxidizing properties.
Description of key information
The test item has no oxidizing properties.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising

Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on available data, the test item is not classified for oxidising properties according to Regulation (EC) No 1272/2008 (CLP), as amended for the tenth time in Regulation (EC) No 2017/776.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
