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, zirconium propionate is considered as
an inorganic substance, and thus a PBT and vPvB assessment is not
The organic moiety of this metal salt, i.e. propionic acid (CAS 79-09-4;
EC 201-176-3), does not have PBT properties because it does not meet the
criteria for persistence (propionic acid is readily biodegradable),
bioaccumulative (bioaccumulation is not expected based on its low logKow
value) and toxicity (no CMR or STOT RE classification and L(E)C50 values
for marine or freshwater organisms are >500 mg/L).
