Additional information

Aquatic toxicity

The following values have been obtained through GLP compliant studies conducted in accordance with recent guidelines. The studies were conclusive and the results are valid.

Short-term toxicity to fish: LC50(96h) = 6.5 mg/L, Tobler 2015

Short-term toxicity to aquatic invertebrates: EC50(48h) = 6.9 mg/L, Tobler 2015

Toxicity to aquatic algae and cyanobacteria: EC50(72h) = 18 mg.L, Tobler 2015

Toxicity to activated sludge: EC50(3h) > 1000 mg/L, Eisner 2015

The most conservative value LC50(96h) = 6.5 mg/L (fish) is carried forward for the purpose of risk assessment, classification and labelling.

Conclusion on classification

Acute aquatic toxicity

The lowest available effect level, LC50(96h) = 6.5 mg/L for Oncorhynchus mykiss (fish), does not trigger classification as an acute aquatic hazard according to CLP Regulation (EC) No 1272/2008, Section 4.1.2.6.

Chronic aquatic toxicity

Adequate chronic toxicity data are not available. However, the lowest available effect level LC50(96h) = 6.5 mg/L for Oncorhynchus mykiss (fish), triggers classification as a Hazardous to the aquatic environment Category Chronic 2, because the substance is not rapidly biodegradable according to CLP Regulation (EC) No 1272/2008, Table 4.1.0(iii).
