Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 studies are available for three trophic levels. The most sensitive organism in acute toxicity testing was Danio rerio with a LC50 of >1.57 mg/l. In Daphnia magna an EC50 of 3.7 mg/l was determined. The EC50 detected in algae (Desmodesmus subspicatus) was > 9.42 mg/l (anal.) and >100 mg/l (nom.) based on algal growth rate.
Chronic aquatic toxicity studies are not available. Considering the a/c-ratio, corresponding studies are not considered to have a relevant influence on the risk assessment and thus no further studies are proposed.
The PNEC calculations are based on the results of the acute toxicity test performed with Danio rerio.For the sediment and terrestric compartments the equilibrium partitioning method has been used.
The PNEC STP was calculated using the EC50 of >1000 mg/l determined in a respiration inhibition test conducted with domestic, activated sludge.
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.
