Conclusion on classification
Based on the data of substance:
Biodegradation: the substance is not readily biodegradable
Partition coefficient: logKow = 3.1
Short-term toxicity to aquatic invertebrates: EC50 (Daphnia magna) at 48h = 0.1 mg/L
Toxicity to aquatic algae and cyanobacteria: ErC50 (Scenedesmus subpsicatus) at 72h > 12.4 < 22.1 mg/L, NOEC(growth rate) at 72h = 9.1 mg/L
Acute aquatic toxicity classification: according to Regulation (EC) No. 1272/2008 the substance should be classified as H400 (category acute 1) as the most sensitive EC50 is <1 mg/L.
Chronic aquatic toxicity classification: according to Regulation (EC) No. 1272/2008 the substance should be classified as H410 (category chronic 1) as the most sensitive EC50 is 0.1 mg/L and the substance is a non-rapidly degradable substance.
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.
