- Endpoint:
- oxidising solids
- Type of information:
- other: expert statement
- Adequacy of study:
- weight of evidence
- Study period:
- September 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: test procedure in accordance with generally accepted scientific standards and described in sufficient details
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- As the ability to predict the reactivity of chemicals compounds from their structure is somewhat limited, the best approach is by analogy with existing compounds whom are known to be oxidisers. As such, there is is a known list of oxidizing compounds and reactive groups which increase the oxidizing power of a molecule. However this list is not exhaustive. If the substance meets one of the above criteria, the lack of any reactive group named in Annex 1 may not
be sufficient to justify not performing the A 17 test.
A full test does not need to be conducted for solids if any preliminary evaluation clearly indicates that the test substance has oxidising properties. - GLP compliance:

- Conclusions:
- Diphenylamine is not potentially oxidising
Referenceopen allclose all
Based on structural group evaluation, the test substance is not potentially oxidising.
Description of key information
An authoritative secondary source peer-reviewed by the Scientific Committee on Health and Environmental Risks (SCHER) and a well-conducted study report determining the oxidising potential of the test substance were used to assess the oxidising properties of Diphenylamine.
These results are assembled together into a weight of evidence determination.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
According to these two sources, Diphenylamine is not potentially oxidising.
Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
