Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Based on Annex VII, Column 2 of the REACH Regulation (EC n. 1907/2006), the study does not to be performed based on the absence of structural alerts.
An oxidising substance is one that, while in itself not necessarily combustible, may cause or contribute to the combustion of other material. Oxidising substances generally act by yielding oxygen; however, those that release active halogens can also act as oxidants.
For organic substances only, is commonly used and accepted a 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 criterium, in combination with chemical structure evaluation, in order to predict whether a substance has the potential to be an oxidant. The oxygen balance is calculated from the empirical formula of a compound in percentage of oxygen required for complete conversion of carbon to carbon dioxide and hydrogen to water.
The oxygen balance is calculated using the formula:
Oxygen balance = - 1600 [2x + (y/2)-z]/molecular weight;
where:
X = number of atoms of carbon
Y = number of atoms of hydrogen
Z = number of atoms of oxygen
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.
Oxygen balance was calculated and resulted equal to - 102.679.
It needs to be considered that the presence of hydroxyl groups will strongly affect the oxygen balance towards higher values, whereas this group does not contribute to explosive properties.
Specific rules for adaptationas decribed in Annex VII, Column 2 of the REACH Regulation (EC n. 1907/2006) can be applied and the oxidising properties test does not need to be conducted.
Justification for classification or non-classification
Classification for oxidising properties is not warranted under CLP Regulation (EC n. 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.
