Aquatic toxicity studies with zinc
ditetradecanoate are not available. In the assessment of zinc
ditetradecanoate, read-across to analogue substances and/or the
assessment entities soluble zinc substances and tetradecanoic/myristic
acid is conservatively applied since the ions of zinc ditetradecanoate
determine its fate and toxicity in the environment.
The EC50 values for the acute toxicity
of the analogue substances zinc dilaurate (zinc salt of a C12-fatty
acid) and Fatty acids, C16-18, zinc salts to Danio rerio are > 10 mg/L
and > 10,000 mg/L, respectively, and thus above the water solubility
limit of zinc ditetradecanoate of 1.14 mg/L. Thus, zinc salts of
shorter- and longer-chained fatty acids appear to have a low potential
for toxicity to freshwater fish. A similar low potential is assumed for
Further, data available for soluble
zinc substances and myristic acid indicate that the moiety of
ecotoxicological concern are zinc cations. Aquatic toxicity data of
myristic acid point to a low toxic potential to aquatic fish as it is
part of their daily diet. The ecotoxic potential of the fatty acid
chain, i.e. myristate, is assumed to be negligible. Fatty acids are
generally not considered to represent a risk to the environment, which
is reflected in their exclusion from REACH registration requirements
(c.f. REACH Annex V (Regulation (EC) No 987/2008)).
