Oxidising properties
Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with column 2 of REACh Annex VII, the study does not need to be conducted if the substance is incapable of reacting exothermically with combustible materials, for example on the basis of the chemical structure.
According to Regulation (EC) N°1272/2008 (CLP) criteria (Annex I §2.13.4./2.14.4., or as listed in the ECHA endpoint specific guidance on information requirements (R.7a, v6.0, July 2017, §R.7.1.13)), the substance contains oxygen atoms, but this element is chemically bonded only to carbon (especially not bonded to nitrogen or other oxygen).
Then oxidising properties are unlikely, and the classification procedure shall not apply, no further testing is required. - Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 16 April 2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- GLP compliant study in compliance with international recognized guidelines.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- Version / remarks:
- 2008
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids)
- Deviations:
- no
- GLP compliance:
- yes
- Contact with:
- powdered cellulose
- Duration of test (contact time):
- 509 s
- Sample tested:
- test mixture (not specified)
- Remarks:
- migrated information
- Parameter:
- maximum burning rate
- Result:
- 505 s
- Remarks on result:
- other: test substance-cellulose 4:1 mixture; mean burning time 494 ± 8.5 seconds
- Sample tested:
- test mixture (not specified)
- Remarks:
- migrated information
- Parameter:
- maximum burning rate
- Result:
- 525 s
- Remarks on result:
- other: test substance-cellulose 1:1 mixture; mean burning time 509 ± 12.5 seconds
- Sample tested:
- reference mixture (not specified)
- Remarks:
- migrated information
- Parameter:
- maximum burning rate
- Result:
- 155 s
- Remarks on result:
- other: potassium bromate-cellulose 3:7; mean burning time 149 ± 5.2 seconds
- Interpretation of results:
- study cannot be used for classification
- Conclusions:
- The mean burning times of the 4:1 and 1:1 sample to cellulose mixtures were significantly higher than the mean burning time of the standard 3:7 mixture of potassium bromate to cellulose.
- Executive summary:
Following EU Method A.17 mixtures of Heliotropine (piperonal) and cellulose were prepared in the oxidiser to cellulose ratios of 4:1 and 1:1, by mass. The mixtures were ignited and the burning time was compared to the reference sample of a potassium bromate to cellulose mixture 3:7, by mass. The mean burning times of the 4:1 and 1:1 sample to cellulose mixtures were significantly higher than the mean burning time of the standard. Heliotropine (piperonal) does not possess oxidizing properties.

Description of key information
In accordance with column 2 of REACh Annex VII, the study on oxidising properties (required in section 7.13) does not need to be conducted if the substance is incapable of reacting exothermically with combustible materials, for example on the basis of the chemical structure.
This is supported by a negative A17 study, but the method is not suitable with regard to CLP criteria.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
Following EU Method A.17 mixtures of Heliotropine (piperonal) and cellulose were prepared in the oxidiser to cellulose ratios of 4:1 and 1:1, by mass. The mixtures were ignited and the burning time was compared to the reference sample of a potassium bromate to cellulose mixture 3:7, by mass. The mean burning times of the 4:1 and 1:1 sample-to-cellulose mixtures were significantly higher than the mean burning time of the standard. Heliotropine (piperonal) does not possess oxidizing properties.
Justification for classification or non-classification
The chemical structure substance meets the exemption criteria, according to Regulation (EC) No 1272/2008, Annex I section 2.14.
This is sufficient for (non-)classification purpose.
In the A.17 study that was used for DSD criteria, the reference mixtures differ from the O1 method used for classification according to CLP, therefore the conclusion cannot be extrapolated. However, the negative result supports the lack of potential for the substance.
