Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification
Short-term aquatic toxicity data are available for two trophic levels (aquatic invertebrates and aquatic algae). The acute effect value, EC50 for Daphnia is 24 mg/l and for the ErC50 for Algae is 9.7 mg/l. Based on the lowest available acute data, for algae the substance does not need to be classified for acute aquatic hazard (CLP 2008, and its amendments: Table 4.1.0 (a). As for only one trophic level chronic toxicity data are available, both chronic toxicity data (in combination with biodegradability) and acute toxicity data (in combination with biodegradability and/or Log Kow) need to be assessed and the most stringent outcome needs to be applied for long-term hazard classification (CLP 2008, and its amendments: Figure 4.1.1.). In view of the substance being readily biodegradable, log Kow of 3.0 and the chronic available value of the ErC10 of algae being 2.8 mg/L, the substance does not need to be classified for long-term aquatic hazard according to Table 4.1.0(b)ii. Based on the acute toxicity data of the other trophic level, being acute Daphnia EC50 of 24 mg/l, and the substance being readily biodegradable and having a Log Kow of 3, the substance does not need to be classified 4.1.0(b)iii according to Regulation 1272/2008/EC (CLP) 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.
