Additional information

Conclusion on classification

The following key information was used for the environmental classication:

Lowest acute E(L)C50 value 3.0 mg/L to Daphnia magna (Noack, 2001)

Lowest chronic NOEC value 25 µg/L to Daphnia magna (Dow Chemical Co., 1991)

Ready biodegradable in an OECD 301B test (Noack, 2001)

Log Kow: <-1.4 (Brekelmans, 2013)

GHS:

Acute: As the lowest EC50 value (to Daphnia magna) was >1 mg/L, the substance is not classified.

Chronic: Two chronic NOEC values are available (to daphnia and algae). As the lowest NOEC value (to Daphnia magna) was > 0.01 mg/L and ≤0.1 mg/L and the substance is ready biodegradable, the substance has to be classified in the Category Chronic 2 with H411.

DSD:

As the lowest EC50 value (to Daphnia magna) was >1 mg/L, the substance is ready biodegradable and the Log Kow <3, the substance is not classified.
