Additional information

- Short-term toxicity to fish: Key study. Method according to OECD TG 302 / EU Method C.1, GLP study. The 96h-EC50 of the test item in zebrafish was determined to be higher tan 100 mg/L and the NOEC was 100 mg/L, both based on mortality.

- Short-term toxicity to aquatic invertebrates: Key study. Method according to OECD TG 202 / EU Method C.2, GLP study. The 48h-EC50 in Daphnids was determined to be higher than 100 mg/L and the 48h-NOEC was determined to be 100 mg/L, both based on mobility.

-Toxicity to aquatic algae and cyanobacteria: Key study. Method according to OECD TG 201 / EU Method C.3, GLP study. The 72h-EC50 of the test item in freshwater algae was determined to be > 100 mg/L, the overall NOEC was determined to be 100 mg/L and the overall LOEC > 100 mg/L, all based on growth rate.

Conclusion on classification

Based on available data (96h-EC50 in fish > 100 mg/L, 48h-EC50 in Daphnids > 100 mg/L, 72h-EC50 in algae > 100 mg/L) and since the substance is readily biodegradable, with a Log Kow < 4, the test item is not classified for aquatic toxicity, according to CLP regulation (EC) No. 1272/2008.
