Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Acute toxicity studies evaluating the toxicity of the substance to aquatic organisms are available for three different trophic levels. All studies were performed according to international guidelines and GLP. Freshwater fish (Danio rerio) turned out to be the most sensitive species with a LC50 (96 h) of 8.43 mg/L followed by aquatic algae (Pseudokirchneriella subcapitata; ErC10 (72 h) of 5.06 mg/L, ErC50 (72 h) of 15.7 mg/L) based on inhibition of growth and aquatic invertebrates (Daphnia magna; EC50 (48 h): 22 mg/L). The substance did not cause inhibition of biodegradation in a biodegradation study according to OECD 310 with activated sludge from a sewage treatment plant. Thus, significant inhibition of the subsequent degradation process in sewage treatment plants is not expected. Based on the result of the toxicity control a NOEC (14 d) of ≥ 20 mg/L was derived.
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.
