Additional information
No studies on terrestrial organisms are available for the substance.
In Annex X, Section 9.4, Column 2 of Regulation (EC) No 1907/2006, it is laid down that long-term toxicity testing shall be proposed by the registrant or may be required by the Agency if the chemical safety assessment indicates the need to investigate further the effects of the substance or of relevant transformation and degradation products on terrestrial organisms.
The integrated testing strategy for the assessment of effects on terrestrial organisms (REACH Guidance Document R.7c; ECHA, 2017) shown in Figures R.7.11-2 and R.7.11-3 lead to the following conclusions.
The substance is readily biodegradable (see IUCLID Ch. 5.2.1); therefore, indirect exposure of soil is not likely.
Data are not available for soil organisms; therefore, the ITS refers to the principle of the soil hazard categories (R.7c: Table R.7.11-2; ECHA, 2017), the substance is assessed as Hazard Category 1. This category includes substances where there is no indication for high adsorption (log Kow > 5, ionisable substances) or high persistence (DT50 > 180 d) as well as no indication for the substance being very toxic (LC/EC50 < 1 mg/L).
2-Ethylhexanoic acid is readily biodegradable (see IUCLID Ch. 5.2.1). The substance has no significant potential for adsorption based on estimated and experimental data (see IUCLID Ch. 5.4.1). The substance is with high probability acutely not harmful to aquatic organisms. In addition, long-term effects are not expected based on long-term testing with aquatic organisms (NOEC/EC10 > 10 mg/L).
As soil is not an environmental compartment of concern, no testing on toxicity to soil organisms is performed. The equilibrium partitioning method can be used for assessing the hazard to soil organisms if required.

The substance is with high probability acutely not harmful. In addition, long-term effects are not expected based on long-term testing with aquatic organisms (NOEC/EC10 > 10 mg/L). Therefore, the equilibrium partitioning method can be applied as a first screen.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
