Description of key information

EC50 (48 h)= 40 mg/L (nominal concentration) for Daphnia magna (OECD 202)
EC50 (48 h)= 28 mg/L (mean measured concentration) for Daphnia magna (OECD 202)

Key value for chemical safety assessment

Additional information

One study evaluating the acute toxicity of methyl hexanoate (CAS No. 106-70-7) to aquatic invertebrates is available (Kimmel, 2013). This test was conducted according to OECD Guideline 202, under GLP conditions. Daphnids were exposed to the test substance for 48 hours within a semi-static water regime at 20 ± 1 °C. Measurements of test concentrations (6.25, 12.5, 25, 50 and100 mg/L nominal) were performed through GC analysis. After 48 hours, 90% and 100% immobilization were reported at the two highest tested concentrations (50 and 100 mg/L, nominal). Therefore, the EC50 (48 h) was determined to be 40 mg/L (nominal), corresponding to a mean measured concentration of 28 mg/L.
