Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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, algae and microorganisms were 2.0, 13, and 60 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 registered substance has a log Pow of << 3 resulting in a low likelihood to partition to sediment and is only moderately toxic to pelagic aquatic organisms. Therefore, the registered substance is not expected to cause adverse effects on sediment organisms. Consequently sediment toxicity tests do not need to be conducted to assess the risk for sediment-dwelling organisms. The PNECs for these endpoints will be calculated using the partition coefficient method.

The fish were the most sensitive trophic level with an acute LC50 of 2.0 mg /L. This value will be used as worst case scenario for the risk assessment of aquatic organisms.
