Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 daphnids and freshwater fish as well as acute and chronic data are available for freshwater algae. Since the registered substance is readily biodegradable, the toxic control as performed together with the biodegradation tests and at a concentration relevant for STP will be used for the assessment of toxicity to aquatic microorganisms. Long-term studies for fish and daphnia are not available for the registered substance. Supporting information from a read across source substance is available for the endpoint long-term invertebrates. The supporting read across information will not be used for the risk assessment. Experimental information about toxicity on marine organisms is not available.
The short-term EC50/LC50 values for fish, Daphnia, algae were > 600.4, 602, and > 995.7, respectively. The EC10 for algae is > 995.7 mg/L.
The registered substance has a log Pow of << 3 resulting in a low likelihood to partition to sediment and is readily biodegradable. 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 (freshwater sediment and marine sediment) will be calculated using the partition coefficient method.
At the tested concentrations, the registered substance is not toxic to aquatic organisms. For the risk assessment the lowest EC50/LC50, will be used, i.e., 600.4 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.
