Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Data waiving in accordance with column 2 of REACH Annex VII. Prediction based on chemical structure: oxidising properties predicted negative (EU Method A.17)Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
Data waiving in accordance with column 2 of REACH Annex VII: the oxidising properties study (required in section 7.13) does not need to be conducted if there are no chemical groups associated with oxidizing properties present in the molecule. The method A.17 Oxidising properties (EC No 440/2008) concurs with this interpretation. For the prediction of oxidizing properties in the substance’s chemical structure, the Handbook of Reactive Chemical Hazards (7th edition, Academic Press, 2007) by Bretherick L. was used. According to the method A.17 and column 2 of Annex VII, if the substance has no reactive chemical groups, the product can be predicted to be non-oxidising and the actual test does not need to be conducted.
In accordance with the literature work by Bretherick, the structure of the commercial hexacyano product does not indicate that there are any oxidising properties associated with the product, e.g. because it contains neither oxygen nor halogen atoms.
Justification for classification or non-classification
The substance has been predicted negative for oxidising properties based on its chemical structure using a procedure compatible with Method A.17 Oxidising Properties (Solids) of Commission Regulation (EC) No 440/2008. The substance is therefore not classified as oxidising.
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.
