Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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


The environmental hazard assessment for (fresh-) water organisms and sediment habitats is supported by several acute studies (pelagic compartment) and by using scientific argumentation (sediment dwelling organisms).

For the environmental hazard assessment of the registered substance acute toxicity studies for freshwater fish, daphnids, freshwater algae and STP microorganisms are available. Long-term studies for fish and daphnids are waived. Experimental information about toxicity on marine organisms is not available.

The short-term EC50/LC50 values for fish, Daphnia and algae were 2.0, 13, and 60 mg/L. A 21 day chronic reproduction study with Daphnia resulted in an EC10 of 1.1 mg/L. Based on the toxic control of a ready biodegradation study with a read across substance, no toxic effects on STP organisms were found at 17 mg/L.

The fish were the most sensitive trophic level in acute tests with an acute LC50 of 2.0 mg /L For algae and daphnids long-term data are available. For long-term studies, Daphnids are the most sensitive species having an EC10 of 1.1 mg/L. The EC10 (1.1 mg/L) value will be used for the risk assessment of aquatic organisms.
