- 24 mg/L
Additional information
The acute toxicity of the substance was studied in a valid GLP test according to OECD 202. The test was performed under semi-static conditions in closed vessels over a period of 48 hours. The 48-hour EC50 was determined to be 24 mg/L with 95%-confidence limits of 21 and 27 mg/L. The NOEC was determined being 12.5 mg/l (48h) and the LOEC 25 mg/l (48h). This finding is supported by the finding with ethyl cinnamate, a structural homologue of methyl cinnamate with similar physico-chemical properties, having an EC50 value (daphnia magna Straus, 48h) of 15 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
