ZINC DILAURATE:Toxicity data are not available for zinc dilaurate. A read-across is made to insoluble/ slightly soluble zinc substances.ZINC:NOEC and EC10 values are available for 18 different species. The NOEC/EC10 values vary between 32 mg Zn/kgdw for Trifolium pratense and Vicia sativa to 5855 mg Zn/kg dw for Triticum aestivum .
ZINC DILAURATE: As terrestrial toxicity data are not available for zinc dilaurate, a read-across is made to insoluble/ slightly soluble zinc substances. It is assumed that upon dissolution zinc dilaurate is changed in part to ionic zinc and that only ionic zinc is determining biological activities. The ecotoxic potential of the fatty acid chain, i.e. laurate, 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)). For a comprehensive overview of the toxicity of zinc, see the hazard assessment of "Zinc" within the framework of Regulation (EC) No 1907/2006 in Appendix 1 of the CSR and cited in excerpts below.
For plants, 45 individual high quality NOECs/EC10 values are selected for PNEC derivation, representing 18 different species. NOEC and EC10 values vary between 32 mg Zn/kgdw for Trifolium pratense and Vicia sativa (Van der Hoeven and Henzen, 1994) to 5855 mg Zn/kg dw for Triticum aestivum (Warne et al., 2008a).
All toxicity data are expressed as added Zn concentration in soil, based on either the nominal dose added or on measured, background corrected soil Zn concentrations.
