Conclusion on classification
Aquatic acute toxicity
48 h, EC50 (Daphnia magna): 3.42 mg/L (meas. TWA)
72 h, ErC50 growth rate (Pseudokirchneriella subcapitata): 0.045 mg/L (meas. geom. mean)
96 h, LC50 (Danio rerio): 14.8 mg/L (nominal)
Aquatic chronic toxicity
72 h, ErC10 growth rate (Pseudokirchneriella subcapitata): 0.029 mg/L (meas. geom. mean)
Classification, Labeling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data of the substance are reliable and suitable for classification purposes under Regulation (EC) No. 1272/2008. The test item was determined be not readily biodegradable based on read-across. In the aquatic tests conducted, the test substance showed toxic effects on the tested species. The determined EC50 for Daphnia magna was 3.42 mg/L and for Pseudokirchneriella subcapitata was 0.045 mg/L (growth rate), while the LC50 in Danio rerio was 14.8 mg/L. The EC10 (growth rate) for Pseudokirchneriella subcapitata was determined to be 0.029 mg/L. Based on these results, the substance is considered as classified for short-term (acute) aquatic toxicity Category Acute 1 (H400: Very toxic to aquatic life, M factor = 10) and classified for long-term (chronic) aquatic toxicity Category Chronic 1 (H410: Very toxic to aquatic life with long lasting effects, M factor = 1) according to Regulation (EC) No 1272/2008 (CLP).
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.
