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 of 2,2-bis[[(1-oxoisononyl)oxy]methyl]-1,3-propanediyl diisononanoate (CAS 93803-89-5) 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 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.No effects on reproduction and mortaility were observed after an exposure period, therefore the NOEC (56 d) was determined to be ≥ 1000 mg/kg dw.
