Description of key information

Read-across to the assessment entities soluble zinc substances and neodecanoic acid is applied for the assessment of zinc neodecanoate, basic since the ions of zinc neodecanoate, basic determine its fate and toxicity in the environment. Reliable data available for soluble zinc substances and neodecanoate indicate that the moiety of ecotoxicological concern are zinc cations. Regarding the toxicity of zinc to freshwater algae, the lowest IC50 value amounts to 0.136 mg Zn/L and the lowest NOEC/EC10 values to 0.019 mg Zn/L and 0.0078 mg Zn/L for freshwater algae and marine algae, respectively. Data for neodecanoic acid indicate a low toxic potential to freshwater algae with a 72-h EL50 of >100 mg/L neodecanoic acid.
