Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was found to be readily biodegradable under the test conditions. Furthermore, a log Kow of 4.8 was taken into account for classification. The most sensitive test for the aquatic compartment was the toxicity test to aquatic invertebrates (Daphnia magna). The 48h EC50 of the test substance was determined to be 3.7 mg/L. Based on these results, the substance is classified as long term (chronic) aquatic toxicity Category 2 (H411: Toxic to aquatic life) according to Regulation (EC) No 1272/2008 (CLP) as amended for the thirteenth time in Commission Regulation (EU) 2018/1480.
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.
