Conclusion on classification

Conclusion on classification

Degradation

Biodegradation: readily biodegradable: 62% after 28 d (CO2 evolution, 10-day window not applicable, OECD 310)

 

Bioaccumulation

log Kow: 4.4 at 40 °C (OECD 117)

 

Aquatic acute toxicity

Fish: 96 h, LC50 (Danio rerio): 8.43 mg/L (nominal)

Aquatic invertebrates: 48 h, EC50 (Daphnia magna): 22.0 mg/L (measured, geometric mean)

Algae: 72 h, ErC50 (Pseudokirchneriella subcapitata): 15.7 mg/L (nominal)

 

Aquatic chronic toxicity

Fish: no data available

Aquatic invertebrates: no data available

Algae: 72 h, ErC10 (Pseudokirchneriella subcapitata): 5.06 mg/L (nominal)

 

Classification according to CLP

Acute toxicity data are available for all three trophic levels whereas chronic data are only available for aquatic algae. The substance is considered to be rapidly degradable in the environment but a potential for bioaccumulation cannot be excluded based on the log Kow of 4.4. Fish was found to be the most sensitive species with a LC50 (96 h) of 8.43 mg/L. Thus, the test substance needs to be classified and labeled as “Aquatic Chronic 2” (H411) according to the 7th ATP of Regulation (EC) No 1272/2008 (CLP).
