Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is acutely toxic to aquatic organisms.
Additional information
Short-term toxicity to fish
Based on a weight-of-evidence approach using experimental and estimated data, it can be concluded that the substance is acutely harmful to fish (96 -h LC50 > 10 to 306 mg/L).
Short-term toxicity to aquatic invertebrates
The substance is acutely harmful to aquatic invertebrates based on the results from an experimental study (OECD 202, GLP, Daphnia magna). The 48 -h EC50 was 32 mg/L (nominal; analytically verified; BASF SE, 2019; report no.50E0503/17X374).
Toxicity to algae
The substance is acutely toxic to fish based on the results from an experimental study (OECD 201, GLP, Pseudokirchneriella subcapitata). The 72 -h ErC50 was 4.96 mg/L and the 72 -h ErC10 was 1.56 mg/L (geometric mean measured; BASF SE, 2019; report no.60E0503/17X373).
Toxicity to microorganisms
The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations based on the results of a respiration inhibition study (OECD 209, GLP, activated sludge, municipal). The 3 -h EC50 was 290 mg/L (nominal; BASF SE, 2019; report no. 08G0503/17G679).
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.
