Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
There are no terrestrial toxicity data available for Monopentaerythritol tetraesters and dipentaerythritol hexaesters of 2-ethylhexanoic and n-valeric acids. Therefore, read-across to the structurally related 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) was conducted in order to fulfil the standard information requirements in compliance with Annex XI, 1.5, of Regulation (EC) No 1907/2006. Based on the high degree of similarity between the structural and physico-chemical properties of the target and source substances, the source substances are considered as suitable representatives for the assessment of the toxicity to soil macroorganisms. A detailed analogue approach justification is provided in the technical dossier (see IUCLID Section 13).
The toxicity to soil macroorganisms was determined according to OECD 222 for the source substance Triisononanoic acid, triester with 2,2’-[oxybis(methylene)]bis[2-(hydroxymethyl)propane-1,3-diol] tris(2-ethylhexanoate) (CAS 68443-84-5). For the source substance Decanoic acid, mixed esters with heptanoic acid, octanoic acid, pentaerythritol and valeric acid (CAS 71010-76-9) the toxicity was determined in a short-term study according to OECD 207. No effects were observed and a of NOEC (56 d) of ≥ 1000 mg/kg dw for Eisenia fetida was determined.
No terrestrial toxicity is expected for other trophic levels compared to soil macroorganisms as well, as there is no indication of terrestrial toxicity.
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.
