Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
EC10 (3 h) > 100 mg/L (nominal) for respiration inhibition of activated sludge (OECD 209)
Key value for chemical safety assessment
Additional information
One study investigating the toxicity of Ditetradecyl fumarate (CAS 10341-03-4) to aquatic microorganisms is available. The static test was conducted according to OECD 209 and GLP using domestic activated sludge as inoculum (Hammer, 2013). Concentrations of 62.5, 125, 250, 500 and 1000 mg/L (nominal) were tested. The test substance was added in the required amounts according to the test concentrations directly to the test vessels. No respiration inhibition was observed up to the highest test substance concentration. The EC10 and EC50 are therefore > 1000 mg/L.
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.
