Conclusion on classification

Classification related key information

- Biodegradation in water: readily biodegradable (69% after 28 d, OECD 301 D)

- Bioaccumulation: log Kow 1.44 (OECD 117)

- Aquatic acute toxicity:

Fish: LC50 (96 h) Danio rerio > 6.2 mg/L (arithmetic mean measured, OECD 203)

Aquatic invertebrates: EC50 (48 h) Daphnia magna = 20 mg/L (geometric mean measured, OECD 202)

Algae: ErC50 (72 h) Pseudokirchneriella subcapitata = 1.6 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 = 0.86 mg/L (geometric mean measured, OECD 201)

Classification justification according to CLP

Based on the data above, the substance is considered to be rapidly degradable in the environment. Bioaccumulation is not expected. Aquatic algae turned out to be the most sensitive organism (ErC10 (72 h) = 0.86 mg/L). Thus, the substance has to be classified and labelled as “Aquatic Chronic 3” (H412) according to the consolidated version Regulation (EC) No 1272/2008 (CLP) and considering all further amendments.
