Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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, invertebrates and algae). The acute effect values for fish (Pimephales promelas), daphnids (Daphnia magna) and algae Desmodesmus subspicatus are >11 mg/L, >10 mg/L and 6.9 mg/L, respectively. Since the lowest acute toxicity value is > 1 mg/L, the substance does not need to be classified as acute aquatic toxic in accordance with EU CLP (EC 1272/2008 and its amendments)
Long-term aquatic toxicity data are available only for aquatic algae for which an ErC10 of 4.1 mg/L was determined. Based on the chronic data and the substance’ readily biodegradability, the substance does not need to be classified for chronic aquatic toxicity. As only one reliable long-term toxicity endpoint is available, chronic classification needs to be based on both chronic and acute data (of the other trophic levels) of which the most stringent outcome is used for the final classification. As the acute data of the other trophic levels (fish and daphnia) does not show toxicity up to the water solubility, the substance being readily biodegradable and a log Kow of 4.4 (no experimental BCF available) the substance does not need to be classified for chronic aquatic toxicity. Overall, it can be concluded that the substance does not need to be classified for chronic aquatic toxicity in accordance with EU CLP (EC 1272/2008 and its amendments).
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.
