Description of key information
The test substance does not contain any groups that act as an oxidizing agent. The oxygen atoms that are present in the molecular structure of the test substance are chemically bonded to carbon or hydrogen. In accordance with column 2 of REACH Annex VII, testing of styrene oxide for oxidising properties does not need to be conducted, as the substance does not contain any structural groups known to be correlated with a tendency to react exothermally with combustible material.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
Justification for classification or non-classification
According to Directive 67/548 EEC as well as GHS Regulation EC No 1272/2008, styrene oxide does not need to be classified with regard to this endpoint and labelling is not required.
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.
