Additional information

Conclusion on classification

Environmental fate and pathways

Biodegradation

Readily biodegradable: 70% after 28 d (OECD 301 F)

Bioaccumulation

Log Kow = -4.38 (EpiSuite v4.11, KOWWIN v1.68)

 

Aquatic acute toxicity

Fish

No effects after 70 h, up to 415 mg/kg body weight (nominal, Cyprinus, carpio, non-guideline, non-GLP, RA-A CAS 520-45-6)

Aquatic invertebrates

EC50 (48 h) > 100 mg/L (nominal, Daphnia magna, OECD 202)

 

Algae

ErC50 (72 h) = 32.1 mg/L, (nominal, P. subcapitata, OECD 201)

 

Aquatic chronic toxicity

Aquatic algae

ErC10 (72 h) = 23.9 mg/L (nominal, Pseudokirchneriella subcapitata, OECD 201)

 

Classification according to CLP

Algae were the most sensitive trophic level. The ErC50 (72 h) of algae was 32.1 mg/L and the ErC10 (72 h) was 23.9 mg/L. Since the substance is readily biodegradable and shows no potential for bioaccumulation, it is not classified and labelled for environmental hazards according to 7th ATP of Regulation (EC) No 1272/2008 based on the available data.
