Conclusion on classification
Classification related key information
- Biodegradation in water: not readily biodegradable (14% after 28 d, OECD 301 F)
- Bioaccumulation: log Pow 4.36 (OECD 123)
- Aquatic acute toxicity:
Fish: LC50 (96 h) Gobiocypris rarus = 5.17 mg/L (geometric mean measured, OECD 203)
Aquatic invertebrates: EC50 (48 h) Daphnia magna = 6.44 mg/L (geometric mean measured, OECD 202)
Algae: ErC50 (72 h) Pseudokirchneriella subcapitata = 9.62 mg/L (geometric mean measured, OECD 201)
- Aquatic chronic toxicity:
Fish: No data available
Aquatic invertebrates: No data available
Algae: ErC10 (72 h) Pseudokirchneriella subcapitata = 2.22 mg/L (geometric mean measured, OECD 201)
Classification justification according to CLP
Based on the data above, the substance is not considered to be rapidly degradable in the environment and bioaccumulation cannot be excluded. Based on the chronic data from aquatic algae (ErC10 (72 h) = 2.22 mg/L) and the acute toxicity to fish (LC50 (96 h) = 5.17 mg/L) the substance has to be classified and labelled as “Aquatic Chronic 2” (H411) according to the Regulation (EC) No 1272/2008 (CLP) and the Regulation (EU) No 1297/2014 (6th ATP).
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).
