Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
On the basis of its chemical structure, the substance is incapable of reacting exothermically with combustible materials.
The substance failed to satisfy the screening criteria reported in the CLP Regulation, which are in principle the same as the wording in Section 6 of Appendix 6 to the UN-MTC[1], because it contains oxygen chemically bonded not only to carbon or hydrogen (i.e. oxygen and nitrogen). For organic substances only, is commonly used and accepted a further screening evaluation that take into account the degree to which a substance can be oxidized, related to the chemical structure: the Oxygen Balance (OB) calculation may be used as a further criterion, in combination with chemical structure evaluation, in order to predict if a substance has a proneness to an oxidising behaviour. A negative oxygen balance is an indication that substance contains less oxygen than is needed; therefore it is not expected that substance may, generally by yielding oxygen, cause, or contribute to the combustion of other materials. Another aspect that has to be taken into account is that the substance is produced and used regularly since many years in Europe, transported in ship from outside Europe at various conditions. Evidences connected to the long experience in handling and use of the molecule confirm that no oxidizing properties have never been observed and reported up to now in the usual conditions of production, stock, transport and use. In conclusion, based on the information and review of the substance, it is deemed not to be potentially oxidising, based on the chemical structure, the oxygen balance values and the known experience in the handling and use of substances.

Justification for classification or non-classification
Based on the information and review of Acid Brown 282, it is deemed not to be potentially oxidising, based on the chemical structure, the oxygen balance values and the known experience in the handling and use of substances.
Therefore, a classification as NON oxidising substance is proposed, according to the CLP Regulation (EC 1272/2008).
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).
