Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to the REACH Regulation EC 1907/2006, Annex VII, Column 2 (specific rules for adaptation from column 1), the 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). Malachite Green Oxalate is incapable of reacting exothermically with combustible materials on the basis of its chemical structure: it contains oxygen/halogens atoms that are not chemically bonded to nitrogen or oxygen.

Justification for classification or non-classification

According to the CLP Regulation (EC 1272/2008), 2.14 section, oxidising solid means a solid substance or mixture which, while in itself is not necessarily combustible, may, generally by yielding oxygen, cause, or contribute to, the combustion of other material.

For organic substances or mixtures 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 Malachite Green Oxalate cation does not contain oxygen, fluorine or chlorine; on the contrary, the counterion contains oxygen atoms, but they are chemically bonded only to carbon and hydrogen, thus it can be stated that the classification procedure shall not apply to Malachite Green Oxalate.

In conclusion, according to the CLP Regulation (EC 1272/2008), the substance does not meet the criteria to be classified as oxidising solid.
