PBT assessment: overall result

PBT status:
PBT assessment does not apply

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 cation is only bound to the negatively charged oxygen in the carboxyl group via an ionic bond, zinc dibenzoate 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. benzoic acid (CAS: 65-85-0), does not have PBT properties because it does not meet the criteria for persistence (benzoic acid is readily biodegradable under aerobic conditions) and bioaccumulation (low potential for bioaccumulation based on Log Kow of 1.88) and toxicity (no CMR or STOT RE classification, long-term NOEC or EC10 values for marine or freshwater organisms are >0.01 mg/L).
