Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Soil toxicity studies of zinc bis(2-ethylhexanoate) are not 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.

Zinc: Chronic toxicity data are available for soil macro-organisms, plants and micro-organisms and the lowest respective endpoints are as follows: EC10 (42-d) = 35.7 mg Zn/kg soil dw (annelid, E. albidus), EC10 (28-d) = 14.6 mg Zn/kg soil dw (collembolan, F. candida), NOEC (24-d) = 32 mg Zn/kg soil dw (plant, V. sativa) and a NOEC (45-d) = 17 mg Zn/kg soil dw (microorganism, respiration), respectively.

2 -ethylhexanoic acid: Soil toxicity data of 2-ethylhexanoate are not available. However, the potential for aquatic toxicity is low and the QSAR-based estimate for earthworms (Ecosar V. 2.0) points to very low (if any) potential for toxicity to soil organisms. In addition, 2-ethylhexanoic acid is readily biodegradable and degrades during STP processes so that soil exposure is highly unlikely.


In sum, zinc bis(2-ethylhexanoate) seems to have some potential for toxicity to soil organisms.
