Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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): 3.2 mg/L based on immobilisation of Daphnia magna (OECD 202)
ErC50 (72 h): 3.1 mg/L based on growth inhibition of Pseudokirchneriella subcapitata (OECD 201)
ErC10 (72 h): 1.4 mg/L based on growth inhibition of Pseudokirchneriella subcapitata (OECD 201)
Additional information
Acute toxicity studies evaluating the toxicity of the substance to aquatic organisms are available for two different trophic levels. All studies were performed according to international guidelines and GLP. No specific sensitivity between the species tested was found since the effect concentrations were in the same range. Testing with aquatic invertebrates resulted in an EC50 (48 h) of 3.2 mg/L whereas an ErC50 (72 h) of 3.1 mg/L and an ErC10 (72 h) of 1.4 mg/L was determined for aquatic algae. All effect values were based on nominal concentrations since the measured concentrations were within the range of 80-120% of nominal.
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.
