Additional information

Conclusion on classification

The substance led to effects in fish, aquatic invertebrates and algae with aquatic invertebrates (Daphnia magna) being the most sensitive. As the lowest EC/LC50 value is > 1 mg/L, no acute classification is deemed appropriate for this substance in accordance with the CLP regulation (EC No. 1272/2008, as amended).

Chronic algae data is available on the substance providing a NOEC value (based on biological significance) of 2.2 mg/L. As this is > 1 mg/L (and the substance is deemed rapidly degradable) no classification for chronic effects is warranted. Taking into account available acute data to derive the chronic classification is not warranted as the substance is readily biodegradable and has a low Log Kow value.
