Additional information
Conclusion on classification
Classification related key information
Biodegradation in water: under test conditions no biodegradation observed
Bioaccumulation: Bioaccumulation in organisms is negligible, based on the calculated log Pow of -3.42 to -2.60
Acute toxicity:
- to fish: LC50 (96h) = 420 mg/L (nominal)
- to aquatic invertebrates: EC50 (48h) = 24.1 mg/L (nominal)
- to algae: ErC50 (72h) = 6.8 mg/L (nominal)
Chronic toxicity:
- to fish
- to aquatic invertebrates: EC10 (21d) = 1.9 mg/L (nominal; read across)
- to algae: NOErC (72 h): 0.5 mg/L (nominal)
Classification justification according to CLP
According to the data listed above the substance is not readily or inherently biodegradable. The acute aquatic toxicity L(E)C50 is >1 mg/L. The chronic NOEC is <0.5 mg/L. Based on the available data the is classified as Aquatic Chronic 2 according to the consolidated version of Regulation (EC) No 1272/2008 (date: 01.03.2018) and further amendments (ATPs).
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).
