Conclusion on classification

Degradation

Biodegradation: not readily biodegradable: 2% after 28 d (OECD 301C)

Bioaccumulation

Log Kow: < 0.3 (OECD 117)

Aquatic toxicity

96 h, LC50 (Oryzias latipes): > 100 mg/L (nominal), > 94.5 mg/L (measured)

48 h, EC50 (Daphnia magna): > 100 mg/L (nominal), > 91.3 mg/L (measured)

72 h, ErC50 (Pseudokirchnerialla subcapitata): > 100 mg/L (nominal), > 89.6 mg/L (measured)

72 h, NOEC (Pseudokirchnerialla subcapitata): 9.5 mg/L (nominal), 4.56 mg/L (measured)

 

Classification according to CLP

Based on the data above, the acute aquatic toxicity L(E)C50 is > 1 mg/L. The test substance does not need to be classified and labeled as acute aquatic hazard according to the 2nd ATP of the Regulation (EC) No. 1272/2008 (CLP).

Chronic aquatic toxicity data are available for algae. Based on the NOEC (72 h) of 4.56 mg/L (measured) which is > 1 mg/L the test substance which is not readily biodegradable does not need to be classified and labeled as chronic aquatic hazard according to the 2nd ATP of the Regulation (EC) No. 1272/2008 (CLP).

Classification according to DSD

Based on the data above, the test substance is considered to be not rapidly degradable and has low potential for bioaccumulation. The acute aquatic toxicity endpoints for fish, daphnids and algae are > 1 mg/L. Thus, the test substance does not need to be classified and labeled according to Directive 67/548/EEC.
