Description of key information
For the substance as such, zinc bis(2-ethylhexanoate), no aquatic toxicity studies are available. Thus, read-across to the assessment entities soluble zinc substances and 2-ethylhexanoic acid is applied since the ions of zinc bis(2-ethylhexanoate) determine its fate and toxicity in the environment.
2-ethylhexanoic acid: The lowest 48-h EC50 of 85.4 mg 2-Et/L was derived from three reliable studies with Daphnia magna in a weight-of-evidence approach.
Zinc: Reliable 48h-EC50 values for Ceriodaphnia dubia range from 0.147 mg Zn/L (geomean) at neutral/high pH and low hardness to >0.53 mg Zn/L (single value) at low pH and high hardness.
Thus, zinc bis(2-ethylhexanoate) has potential for short-term toxicity to aquatic invertebrates.
