Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 5 March 2021
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.21 (Oxidising Properties (Liquids))
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Contact with:
- powdered cellulose
- Duration of test (contact time):
- > 1 - < 10 min
- Sample tested:
- test mixture 1:1
- Remarks:
- Test material: 40 % aqueous solution.
- Parameter:
- mean pressure rise time
- Result:
- 29.8 s
- Remarks on result:
- spontaneous ignition does not occur
- Remarks:
- For each test material mixture it was noted that a strong exothermic reaction took place during the mixing procedure. Smoke was emitted, and the mixture changed colour from purple to grey. Spontaneous ignition did not occur.
- Interpretation of results:
- other: Not classified according to EU Criteria
- Conclusions:
- Under the conditions of the study the test material (as a 40 % aqueous solution) is non-oxidising and does not meet the criteria for classification as an oxidiser in this form.
- Executive summary:
The oxidising properties of the test material (as a 40 % aqueous solution) were assessed according to EC Method A.21 and in compliance with GLP.
The results of the definitive test demonstrate that the time taken for the pressure rise is longer for the test material mixtures than for the reference mixture, suggesting that the test material (as a 40 % aqueous solution) is non-oxidising and does not meet the criteria for classification as an oxidiser in this form. However, the strong exothermic reaction and colour change observed during the mixing procedure could be considered to be indicative of oxidising properties.
Under conditions of the study the test material (as a 40 % aqueous solution) is non-oxidising and does not meet the criteria for classification as an oxidiser in this form.

For each test material mixture it was noted that a strong exothermic reaction took place during the mixing procedure. Smoke was emitted, and the mixture changed colour from purple to grey. Spontaneous ignition did not occur, therefore the test was continued.
A pressure of 2 070 kPa was not achieved within 60 seconds for test material samples 2, 3 and 5. The mean pressure rise time for the reference mixture (1:1 w/w mixture of 65 % w/w aqueous nitric acid and cellulose) was 3.6 seconds, while the mean pressure rise time for the test material mixture (1:1 w/w mixture of test material and cellulose) was 29.8 seconds.

Additional information
Key Study: Cage (2021)
The oxidising properties of the test material (as a 40 % aqueous solution) were assessed according to EC Method A.21 and in compliance with GLP. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
The results of the definitive test demonstrate that the time taken for the pressure rise is longer for the test material mixtures than for the reference mixture, suggesting that the test material (as a 40 % aqueous solution) is non-oxidising and does not meet the criteria for classification as an oxidiser in this form. However, the strong exothermic reaction and colour change observed during the mixing procedure could be considered to be indicative of oxidising properties.
Under conditions of the study the test material (as a 40 % aqueous solution) is non-oxidising and does not meet the criteria for classification as an oxidiser in this form.
Supporting Study: Kashini (2014)
The oxidising properties of 40, 45 and 50 % test material solutions were assessed according to UN Test O.2 “Test for Oxidising Liquids" under controlled laboratory conditions. The purpose of the testing was to determine the potential of a liquid substance to increase the burning rate or burning intensity of a combustible substance (fibrous cellulose) when the two were thoroughly mixed. Additionally, this test determined if the resulting mixture ignites spontaneously. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).
Ignition was observed with both the 45 % and 50 % concentration test samples. There was no visible ignition with the 40 % concentration test sample therefore the UN Test O.2 Test for Oxidising Liquid Test were conducted.
Under the conditions of the study a 40 % Sodium Permanganate Solution is classified as an oxidising liquid category 2 according to EU criteria.
Conclusion
Classification for CLP is based on the 2021 EC Method A.21 study conducted in compliance with GLP as a more reliable indicator of the oxidising potential of the substance.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the material does not require classification with respect to oxidising properties.
