Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
EC50 (48 h) Daphnia magna = 8.37 mg/L (geometric mean measured, OECD 202)
ErC50 (72 h) Pseudokirchneriella subcapitata = 21.3 mg/L (geometric mean measured, OECD 201)
ErC10 (72 h) Pseudokirchneriella subcapitata = 16.1 mg/L (geometric mean measured concentration, OECD 201)
Additional information
Experimental studies evaluating the toxicity of the substance to aquatic organisms are available for two different trophic levels (aquatic invertebrates and algae).
The studies were performed according to international guidelines and GLP. Daphnia magna turned out to be the more sensitive species with an EC50 (48 h) of 8.37 mg/L based on mobility of the test species. Testing with aquatic algae resulted in an ErC50 (72 h) of 21.3 mg/L and an ErC10 (72 h) of 16.1 mg/L. All effect values were based on the geometric mean measured concentrations.
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.
