Description of key information

No effects up to the water solubility limit for Daphnia magna (OECD 211).

Key value for chemical safety assessment

Additional information

One experimental study is available investigating the chronic effects of Fatty acids, vegetable-oil, esters with dipropylene glycol (CAS 95009-41-9) to the freshwater invertebrate Daphnia magna (Muckle, 2014). The study was performed according to OECD 211 as a limit test. A test substance concentration of 1000 mg/L was prepared as water accommodated fraction (WAF) and the corresponding loading rate was tested. Chemical analysis by GC could not quantify the substance in the test solutions as the measured concentrations were below the Limit of Quantification (LOQ; 0.057 mg/L). The reproduction of Daphnia magna was not inhibited after 21 d resulting in a NOELR of ≥ 1000 mg/L (corresponding to ≥ 57 µg/L based on the LOQ).
