Classification according to CLP
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was found to not be readily biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the long-term toxicity test to fish. This study revealed a 215-d EC10 of 1.27 µg a.s./L. Based on these results, the substance is classified as short-term (acute) aquatic toxicity Cat. 1 (M-Factor = 10) and is classified as long-term (chronic) aquatic toxicity in Cat. 1 (M-Factor = 10) according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Commission Regulation (EU) 2020/1182.
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.
