Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Oxidising properties
Administrative data
- 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 UVCB substance is anticipated to contain esters*, which have oxygens in their structure, but this element is chemically bonded only to carbon (especially not bonded to nitrogen or other oxygen). Hydrocarbons* are not relevant, as they do not contain oxygen (or halogen) atoms.
Then oxidising properties are unlikely, and the classification procedure shall not apply, no further testing is required.
* For the major fraction of the UVCB (ca 99.7% non-volatile), direct identification was not achieved, due to technical difficulties. The starting material, beeswax is a complex mixture of saturated and unsaturated linear and complex esters (27 to 40% monoesters, 9 to 23 % hydroxymonoesters, 7 to 16% diesters, 3.9% hydroxydiesters), 11 to 28% hydrocarbons, 1 to 18% saturated, unbranched free fatty acids, 4 to 8% of other substances and < 0.3% free fatty alcohols (EFSA Journal (2007) 615, 1-28). The registered substance Concrete of honeycomb cells of the bee by hexane extraction is anticipated to contain selectively extracted constituents. Hexane being a non-polar solvent, non-hydroxy esters and hydrocarbons are supposed to be predominant in the concrete.

Applicant's summary and conclusion
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
