Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
There are aquatic ecotoxicological data from three throphic levels available (fish, Daphnia magna and alga). The majority of the studies were conducted above the solubility limit without analytical monitoring. However, although above solubility, no effects were observed for fish and Daphnia. The algae study that was conducted according to current standard testing guidelines also did not reveal any effects at the highest soluble concentration. The EC50 for growth rate at 72 hours was estimated to be >38.6 mg/L. The data indicate that in the range of the water solubility limit dodecanedioic does not pose a significant hazard to aquatic organisms. Given that the NOEC for the alga study (11.1 mg/L measured) is lower than the endpoints reported for the fish and Daphnia studies, the ErC50 from the algae study will be used to derive PNEC values.
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.
