Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
LC50 (10 d) = 8643.55 mg/kg sediment dw (OSPARCOM, Corophium volutator)
Key value for chemical safety assessment
Additional information
One experimental marine study investigating the toxicity of Fatty acids, C16-18, tetraesters with 3,3'-oxybis[1,2-propanediol] (CAS 91050-80-5) to Corophium volutator is available (Hudson, 2008). The study was conducted according to OSPARCOM (2005) under GLP conditions. Corophium volutator was exposed to five nominal concentration between 100 and 10000 mg/kg sediment dw with natural sediment in a semi-static test for 10 days. An LC50 (10 d) of 8643.55 mg/kg sediment dw was derived. The substance is readily biodegradable and available acute data for sediment and aquatic organisms and chronic data for terrestrial organisms indicate low toxicity. Long-term testing of sediment organisms is therefore not considered necessary.
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.
