Conclusion on classification

Environmental fate and pathways


Not readily biodegradable: 4% in 28 d (activated sludge, domestic, non-adapted, OECD 301 F)


log Kow = 3.94 at 22.7 °C (OECD 117, HPLC method)


Aquatic acute toxicity

Aquatic invertebrates

EC50 (48 h) = 1.34 mg/L (geom. mean measured conc., D. magna, OECD 202)


ErC50 (72 h) = 6.49 mg/L (geometric mean measured, P. subcapitata, OECD 201)


Aquatic chronic toxicity


ErC10 (72 h) = 1.01 mg/L (geometric mean measured, P. subcapitata, OECD 201)



Acute effect concentrations are available for two trophic levels (aquatic invertebrates and algae) and one chronic effect concentration is available for a single trophic level (algae). Both EC50 values for acute toxicity are in the same order of magnitude and > 1 mg/L. Therefore, no acute hazard arises from the substance for the environment. However, the EC50 values are < 10 mg/L and the substance is not readily biodegradable according to OECD criteria (4% in 28 d, OECD 301 F). Therefore the substance is classified and labelled as Category Chronic 2 for environmental hazards, according to the consolidated version of Regulation (EC) No 1272/2008 (dated: 01.01.2017) and further amendments (ATPs).
