Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
EC50 (48 h)= 1.1 mg/L (measured average concentration) for Daphnia magna (OECD 202)
Key value for chemical safety assessment
Additional information
One study evaluating the acute toxicity of methyl decanoate (CAS No. 110-42-9) to aquatic invertebrates is available (Bouwman, 2010). 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 (loading rate at 100 mg/L and dilutions) were performed through GC analysis. After 48 hours, effects on daphnids mobility were reported at the two highest tested concentrations, 1.9 and 4 mg/L (measured average)(90 and 100% immobility, respectively), whereas no significant effects were observed at lower concentrations (0.74 mg/L and below (measured average)). Therefore, the EC50 (48 h) was determined to be 1.1 mg/L (measured average concentration).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
