Description of key information
NOEC (56 d) ≥ 1000 mg/kg dw (OECD 222)
Key value for chemical safety assessment
Additional information
One study investigating the long-term toxicity ofcarboxylic acids, C5-9, hexaesters with dipentaerythritol (CAS 67762-52-1)to earthworm is available. The GLP study was performed with Eisenia fetida according to OECD 222 (Eisner, 2013). The test substance was homogeneously mixed into artificial soil with the following nominal concentrations 62.5, 125, 500 and 1000 mg/kg dw soil. Earthworms were exposed to treated soil for four weeks. The cocoons and juvenile earthworms remained in the vessels for additional four weeks. Since no effects on reproduction and mortality were observed, the NOEC (56 d) was determined to be ≥ 1000 mg/kg dw.
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.
