Justification:

A PBT and vPvB assessment shall be conducted as foreseen in Article 14 (3) (d) in conjunction with Annex I Section 4 according to the criteria as laid down in Annex XIII. According to Annex XIII of regulation (EC) 1907/2006 a PBT and vPvB assessment shall not apply to inorganic substances, but shall apply to organo-metal. Organo-metal compounds are defined as organic compounds that contain at least one metal or metalloid atom bound to a carbon atom. Because in metal carboxylates, the metal is only bound to the negatively charged oxygen in the carboxyl group via an ionic bond, 2-ethylhexanoic acid, molybdenum salt is considered as an inorganic substance, and thus a PBT and vPvB assessment is not required.

The organic moiety of this metal salt, i.e. 2-ethyl hexanoic acid (CAS: 149-57-5), does not have PBT properties because it does not meet the criteria for persistence (2-ethyl hexanoic acid is readily biodegradable) and bioaccumulative (bioaccumulation is not expected based on its low logKow value).
