Additional information

Conclusion on classification

Classification related key information

- Biodegradation in water: inherently biodegradable, not fulfilling specific criteria (EU Method C.4-E)

- Hydrolysis: Half-live of 133h (pH7) (OECD 111)

- Bioaccumulation: log Pow 4.39 (OECD 123)

 

- Aquatic acute toxicity:

Fish: LC50 (96 h) = 6.72 mg/L (OECD 203)

Aquatic invertebrates: EC50 (48 h) = 9.1 mg/L (EU Method C.2)

Algae: ECr50 (72 h) = 2.7 mg/L (OECD 201)

- Aquatic chronic toxicity:

Fish: No data available

Aquatic invertebrates: No data available

Algae: ErC10 (72 h) = 0.61 mg/L

Classification justification according to CLP

Based on the data above, the substance is considered to be rapidly degradable in the environment (half-live < 16 days and degradation products not classified as hazardous) but bioaccumulation cannot be excluded. Based on the chronic data from aquatic algae (ErC10 (72 h) = 0.61 mg/L) and the acute toxicity to fish (LC50 (96 h) = 6.72 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).
