Endpoint:
explosive properties of explosives
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

Description of key information

Cobalt oxide does not contain functional groups that are directly associated with explosive properties. It is therefore considered to be void of any explosive properties.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

According to Regulation (EC) No 1907/2006, Annex VII, Section 7.11 Column 2 and ECHA Guidance on information requirements and chemical safety assessment, Chapter R.7a: Endpoint specific guidance, section R.7.1.11, December 2016, the study does not need to be conducted. This substance is void of any chemical structures commonly associated with explosive properties, such as metal peroxides, peroxo-acid-anions, azides, and halogen oxides. The substance cobalt oxide is considered to be “inert” in the context of explosivity, since it already represents cobalt in its most stable oxidation status. Further, it is noted that despite the long-term use of cobalt oxide, this substance is not classified for explosive properties according to UN transport regulations.

Justification for classification or non-classification

Cobalt oxalate does not need to be classified according to CLP Regulation (EC) No 1272/2008 since explosive properties are considered non-relevant based on the lack of functional group.
