Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
Short-term aquatic toxicity data are available for freshwater species of three trophic levels (fish, aquatic invertebrates and aquatic algae). The acute effect values for fish (C. carpio), daphnids (D. magna) and algae (P. subcapitata) are 4.1 mg/l, 3.4 mg/l and 5.3 mg/l, respectively. The substance does not need to be classified for acute aquatic hazard because all acute values are > 1 mg/l. Long-term aquatic toxicity data are available only for aquatic algae for which ErC10 and NOEC values were determined at 2.0 and 1.1 mg/l, respectively. As the available chronic effect values are >1 mg/l, chronic classification needs to be based only on acute data. The substance is readily biodegradable, has a log Kow of 5.5 an in vitro BCF indicating a value of 502 and a lowest acute effect value in the range of 1-10 mg/L based on which it is classified as Chronic 2 (H411: Toxic to aquatic life with long lasting effects) according to Regulation 1272/2008/EC (CLP) and its updates.
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.
