Additional information
In a key study, the acute aquatic toxicity towards Daphnia magna was investigated according to OECD guideline 202 under GLP. Daphnids were exposed to nominal concentrations (corrected for active ingredient) of 40, 72, 128, 224 and 400 mg/L. No effects were observed after 48 hours. The 24h- and 48-EC50 were found to be > 400 mg a.i./L.
Two supporting studies (both limit tests with reliability 4) report 48h-NOECs and 48h-EC50s of > 100 mg (a.i.)/L.
Work on a similar substnce that is being used for some read-across, sodium β-Alanine, N-(2-carboxyethyl)-, N-coco alkyl derivs., EC 290-476-8, suggested slightly higher toxicity to Daphnia.
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.
