Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 three trophic levels (fish, aquatic invertebrates, and algae). The lowest observed acute effect concentration was 105 mg/L in daphnids (Daphnia magna). Consequently, the substance does not need to be classified for acute aquatic hazard.
Long-term aquatic toxicity data are available only for aquatic algae, for which no effect level could be derived due to the absence of toxic effects (ErC10 > 222 mg/L). Based on this chronic data, the substance does not need to be classified for chronic hazard.
As only one reliable long-term toxicity endpoint is available, chronic classification needs to be based on both chronic and acute data of which the most stringent outcome is used for the final classification. As the (lowest) acute effect value is > 100 mg/L, the substance does not need to be classified for a chronic hazard based on acute data. Therefore, the substance is not classified for aquatic hazard as accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
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.
