Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
At the limit concentration of nominal 10 µg/l, corresponding to the time weighted mean measured concentration of 5.73 µg/l and above the water solubility level, no effects of dodecyl methacrylate on reproduction and immobilisation of daphnids were determined.
Key value for chemical safety assessment
Additional information
In a chronic toxicity study on daphnia magna with dodecyl methacrylate, a 21-day NOEC of >= 5.73 µg/l was observed.
At the limit concentration of nominal 10 µg/l, corresponding to the time weighted mean measured concentration of 5.73 µg/l and above the water solubility level, no effects of dodecyl methacrylate on reproduction and immobilisation of daphnids were determined.
The test has some restriction on validity as the test concentration exceeds the water solubility of < 1 µg/l for dodecyl methacrylate. However, the absence of adverse effects to daphnia in the range of water solubility was clearly demonstrated.
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.
