Additional information
Conclusion on classification
Aquatic short-term (acute) toxicity
48-h EC50 (Daphnia magna): > 100 mg/L (nominal)
72-h EC50 (growth rate; Raphidocelis subcapitata): > 3.02 mg/L (geometric mean measured)
Aquatic long-term (chronic) toxicity
EC10 (grwoth rate; Raphidocelis subcapitata): 2.45 mg/L (geometric mean measured)
Biodegradation in water: screening tests
The substance is readily biodegradable (according to OECD criteria).
Partition coefficient octanol/water
Using KOWWIN v1.68 the log Pow of the test item was calculated to be -5.05 at 25 °C.
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was found to be readily biodegradable by OECD criteria. The log Pow of the test item was calculated to be -5.05 at 25 °C. The most sensitive test for the aquatic compartment was the toxicity test to algae (Raphidocelis subcapitata). The 72-h ErC10 and the ErC50 (growth rate) of the test substance was determined to be 2.45 and > 3.02 mg/L (geometric mean measured), respectively. The 72-h NOEC-values for both inhibition of growth rate and yield after 72 hours were 1.90 mg/L (geometric mean measured). The 48-h EC50 for Daphnia magna was determined to be > 100 mg/L (nominal). Based on these results, the substance is neither classified for short term (acute) aquatic toxicity, nor for long term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP) as amended for the tenth time in Commission Regulation (EU) 2017/776.Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
