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 dichloride 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 because there are no chemical groups present in the molecule which are associated with explosive properties. Cobalt dichloride consists of cobalt cations and the chloride anions which can all be considered as “inert” in the context of explosivity. Therefore, the substance “cobalt dichloride“ may also considered to be void of any explosive properties. Further, it is noted that despite long-term industrial use of the substance, it is not classified for explosive properties according to UN transport regulations.

Justification for classification or non-classification

Cobalt dichloride 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.
