Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 = 2.3 mg/L (arithmetic mean measured, OECD 202)
ErC50 (72 h) Pseudokirchneriella subcapitata = 0.23 mg/L (geometric mean measured, OECD 201)
ErC10 (72 h) Pseudokirchneriella subcapitata = 0.15 mg/L (geometric mean measured, OECD 201)
Additional information
Two OECD guideline studies (GLP) are available, which assessed the aquatic toxicity of the substance on two different trophic levels. The aquatic algae (Pseudokirchneriella subcapitata) turned out to be the most sensitive organism with an ErC50 (72 h) of 0.23 mg/L (geometric mean measured concentration) based on the inhibition of growth rate followed by the aquatic invertebrates (Daphnia magna; EC50 (48 h): 2.3 mg/L based on arithmetic 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.
