Additional information

An oxidizing 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 react as oxidants. (Ref. 1)

Due to the absence of chemical groups associated with oxidizing properties or other structural alerts the abovementioned substance is not considered to exhibit oxidizing properties.

In accordance with column 2 (Specific rules for adaptation from column 1) of REGULATION (EC) No 1907/2006 (REACH), 7.13 (Oxidising properties), a study does not need to be conducted if 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).

 

Therefore testing for oxidizing properties does not need to be performed.

Justification for classification or non-classification

According to REGULATION (EC) No 1272/2008 (CLP) for organic substances or mixtures the classification procedure for the class of oxidising liquids 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.

The substance does not contain any oxidizing groups and all oxygen atoms present in the molecular structure are bonded directely to carbon. Therefore classification for oxidising properties is not warranted.
