Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Short-term aquatic toxicity data is available from studies with representatives of 3 trophic levels (fish, aquatic invertebrates, and algae). Long-term aquatic toxicity data is available only from a study with algae. No short-term toxicity is recorded at levels in excess of solubility in test medium, the L(E)C50 for classification purposes may be considered to be greater than the measured solubility in mdeium. Therefore, no hazard was identified and no PNECs derived.
No sediment/soil toxicity data is available for the substance, or required for this tonnage level. As no PNECaqua is available, not equilibrium partitioning method calculation for PNECs for sediments and soil can be performed.
Conclusion on classification
No acute aquatic and/or chronic toxicity was recorded at levels up to the limit of solubility in test medium. The substance is assessed to be 'rapidly degradable' based on the findings in a biodegradation screening study (OECD TG 301B) and supported by BIOWIN calculations. Therefore, the substance is not classified for the environment.
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.
