Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Key value for chemical safety assessment
Additional information
In the aquatic toxicity studies microorganisms (EC50[180min]=140 mg/L) were clearly less sensitive than fish (EC50[96h]=4.6-10 mg/L), Daphnia magna (EC50[48h]=3.5 mg/L) and algae (EC50[72h]=97 mg/L) indicating that prokaryotic cells are less sensitive than eukaryotic cells. The most sensitive acute endpoint is 50-fold lower than the result of the activated sludge respiration inhibition test. Hence it is very unlikely that terrestric micro-organisms are more sensitive than terrestrial plants.
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.
