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 ecotoloxicological concern are zinc cations. Species NOECs of 7 freshwater species range from 0.044 to 0.530 mg Zn/L (dissolved). The NOEC available for one marine fish species amounts to 0.025 mg Zn/L (dissolved). The14-d NOEC of 2.22 mg/L neodecanoic acid for growth of Oncorhynchus mykiss supported by the chronic Value (ChV) of 1.6 mg/L (QSAR-based estimate) for fish indicate a low potential for long-term toxicity of neodecanoate to fish.
