Description of key information

No toxic effects up to the limit of water solubility (< 0.0004 mg/L in aqua dest) for Daphnia magna (OECD 202)

Key value for chemical safety assessment

Additional information

One study investigating the short-term toxicity of Bis(2 -ethylhexyl) azelate (CAS 103-24-2) to aquatic invertebrates is available. The semi-static study was conducted by a Japanese authority according to GLP and OECD guideline 202 using Daphnia magna as test organism (MOE, 2004). A technical product of the substance (77.2% purity) was tested at a nominal test concentration of 0.1 mg/L using HCO-40 as vehicle. A measured test concentration of 0.0931 mg/L can be considered as highest achievable test substance concentration using a vehicle under test conditions. No mortality was observed during an exposure time of 48 h. Hence, the 48 h-EC50 is determined to be > 0.0931 mg/L (meas.) and thus above the solubility of the substance in water.
