Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 aquatic toxicity tests with the substance in different freshwater species from three trophic levels are available.
There was no acute toxicity in freshwater fish (Fathead minnow, 96-hours static, LC50 = 934 mg/L), in freshwater invertebrates (Daphnia magna, 48-hours static, EC50 = 700 mg/L) and in freshwater green algae (Pseudokirchneriella subcapitata, 72-hours static, ErC50 = 43.1 mg/L). The long-term toxicity of the substance of the most sensitive aquatic freshwater organisms algae shows a 72h-ErC10 = 13.5 mg/L and a 96h(72h) NOEC = 3.2 mg/L. Data for the toxicity to marine organisms are not available (for waiving arguments refer to CSR section 7.1.1.2. and 7.1.2.2.).
There was no inhibitory toxicity of the substance to activated, predominantly domestic sewage sludge. The 3h-IC50 value in an activated sludge respiration inhibition test was 321.4 mg/L (95 % confidence interval: 186.9 –657.4 mg/L) and the 3h-IC10 = 54.4 mg/L (95 % confidence interval: 29.1 - 82.2 mg/L).
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.
