Description of key information
The chemical safety assessment according to Annex I of Regulation (EC) No. 1907/2006 does not indicate the need to investigate further the toxicity to terrestrial arthropods.
Key value for chemical safety assessment
Additional information
In accordance with Regulation (EC) No 1907/2006, Annex IX, column 2, 9.4 further studies on the effects on terrestrial organisms do not have to be conducted since the chemical safety assessment indicates that there is no need. No experimental data on toxicity to terrestrial arthropods are available for Monopentaerythritol tetraesters and dipentaerythritol hexaesters of 2-ethylhexanoic and n-valeric acids. The test substance is characterised by a high log Koc (log Koc > 5) indicating a considerable potential for adsorption to soil particles. Tests with soil-dwelling organisms like the earthworm allows potential uptake via surface contact, soil particle ingestion and porewater (ECHA, 2017). Thus, this study is most relevant for the evaluation of soil toxicity of substances with a high potential for adsorption.
Read-across in accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5 from the structurally related source substances Triisononanoic acid, triester with 2,2’-[oxybis(methylene)]bis[2-(hydroxymethyl)propane-1,3-diol] tris(2-ethylhexanoate) (CAS 68443-84-5) and Decanoic acid, mixed esters with heptanoic acid, octanoic acid, pentaerythritol and valeric acid (CAS 71010-76-9) resulted in no toxicity to terrestrial macroorganisms (NOEC (56 d) ≥ 1000 mg/kg soil dw). Thus, the available data investigating the toxicity to terrestrial macroorganisms are sufficient to assess the hazard of Monopentaerythritol tetraesters and dipentaerythritol hexaesters of 2-ethylhexanoic and n-valeric acids to terrestrial organisms and no further studies are considered necessary.
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.
