Oxidising properties
Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- other: Structural assessment
- Adequacy of study:
- key study
- Study period:
- Not specified
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- A structural group evaluation was performed and the oxygen balance was calculated.
- GLP compliance:
- no
- Remarks:
- No laboratory work was conducted, therefore GLP compliance was not required.
- Key result
- Parameter:
- other: Structural assessment and oxygen balance calculation
- Remarks on result:
- other: The test material is deemed not to be potentially oxidising, based on the chemical structure and oxygen balance values.
- Interpretation of results:
- other: Not classified according to EU criteria.
- Conclusions:
- Based on the chemical structure evaluation and oxygen balance values, the test material is deemed not to be an oxidiser.
- Executive summary:
The regulatory position with regards to oxidising properties is that a study does not need to be conducted if the substance is explosive; or the substance is highly flammable; or the substance is an organic peroxide; or the substance is incapable of reacting exothermically with combustible materials, for example on the basis of the chemical structure (e.g. organic substances not containing oxygen or halogen atoms and these elements are not chemically bonded to nitrogen or oxygen, or inorganic substances not containing oxygen or halogen atoms).
For organic substances only, an Oxygen Balance (OB) calculation may be useful as a criteria combined with an examination of the chemical structure as a means of predicting oxidising properties. The oxygen balance is calculated from the empirical formula of a compound in percentage of oxygen required for complete conversion of carbon to carbon dioxide, hydrogen to water, and metal to metal oxide.
Based on the information and review of the structure of the test material, the substance is deemed not to be potentially oxidising, based on the chemical structure and oxygen balance values. The substance contains no structural indications of propensity to cause oxidation, and the oxygen balance is not indicative of excess oxygen. On this basis the substance is predicted to not be an oxidiser.

Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to oxidising properties.
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).
