Conclusion on classification
Short-term toxicity results for Daphnia and algae are available for the substance. The EC50 value for Daphnia is 3.7 mg/L. The ErC50 for algae is 4.9 mg/L. Since all acute L(E)C50 values are > 1 mg/L, the substance does not need to be classified for acute aquatic toxicity. One chronic value is available for algae being EC10 of 1.7 mg/l on which bases there is no need for chronic classification: according to Table 4.1.0, (b) (i). However when only one chronic value is available the classification needs to be derived on both acute and chronic information and the most stringent outcome should be leading:
As the EC50 value for Daphnia is >1 - <=10 mg/L and the substance is not readily biodegradable, the substance needs to be classified for chronic toxicity in Category 2 according to Table 4.1.0, (b) (iii). This is the most stringent outcome. This means that overall, it can be concluded that the substance needs to be classified for environmental hazards as Chronic Cat. 2: H411 according to EU CLP (EC 1272/2008 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.
