Reference
Endpoint:
oxidising solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 28 June 2005 to 4 October 2005
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Reason / purpose for cross-reference:
reference to same study
Qualifier:
according to guideline
Guideline:
EU Method A.17 (Oxidising Properties (Solids))
Deviations:
yes
Remarks:
See below for details
Principles of method if other than guideline:
Deviation: normally the test item is reduced to a particle size < 125 µm by grinding, sieving and drying at 50 °c under vacuum until constant weight. Here, it was not possible to reduce the particle size to 125 µm because the test item was sticky. Thus the test item had been tested as it is. As indicated by the study director, it is supposed that the results would be the same for material with a particle size less than 125 µm.
GLP compliance:
yes (incl. QA statement)
Contact with:
powdered cellulose
Key result
Sample tested:
test mixture as specified
Remarks:
Mixtures of test item (10 to 90%) and cellulose (90 to 10%).
Parameter:
burning rate
Remarks on result:
other: The test item burns but the flame stops.

Preliminary test:

Reference mixture (barium nitrate / cellulose ratio 2/1) took 99 seconds to burn. The combustion of the substance mixture (test item / cellulose – ratio 2/1) took 405 seconds to burn.

Iron oxide isostearate has no oxidising properties under the conditions of the test.

Interpretation of results:
GHS criteria not met
Conclusions:
Iron oxide isostearate has no oxidising properties under the conditions of the test.
Executive summary:

The determination of the oxidising properties of iron oxide isostearate was performed according to EU Method A17 and GLP.

Iron oxide isostearate has no oxidising properties under the conditions of the test.

Description of key information

Iron oxide isostearate has no oxidising properties under the conditions of the test.

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

A GLP experimental study, according to EU Method A.17 and scored as Klimisch 1, is selected as a key study, indicating that iron oxide isostearate has no oxidising properties under the conditions of the test.

Justification for classification or non-classification

Based on the above data, iron oxide isostearate does not require a classification regarding its oxidising properties under CLP.
