Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- non oxidising
Additional information
The study does not need to be conducted because the substance is incapable of reacting exothermically with combustible materials on the basis of the chemical structure (the organic substance contains oxygen which is not chemically bonded to nitrogen or oxygen).
Justification for classification or non-classification
According to the CLP Regulation EC 1272/2008 2.14.4.1 section, for organic substances the classification procedure for the oxidising solid class shall not apply if:
(a) the substance or mixture does not contain oxygen, fluorine or chlorine; or
(b) the substance or mixture contains oxygen, fluorine or chlorine and these elements are chemically bonded only to carbon or hydrogen.
For inorganic substances or mixtures the classification procedure for this class shall not apply if they do not contain oxygen or halogen atoms.
The substance to be registered failed to satisfy the screening criteria reported in CLP regulation,because it contains oxygen chemically bonded not only to carbon or hydrogen (i.e. SO3-).
However, based on REACH Regulation EC 1907/2006, Annex VII, Column 2, the study does not need to be conducted if:
- the substance is explosive
- the substance is highly flammable
- the substance is an organic peroxide
- 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).
According to this second definition, the substance has been not tested because it doesn't contain chemical group associated to oxidizing properties. Further evaluation has been done on oxygen balance and chemical fragments of the molecule.
Based on the information and review on the substance, it is deemed not to be potentially oxidising, based on the chemical structure. The substance is not classified as an oxidising solid according o the CLP Regulation (EC) No.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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
