Additional information
Conclusion on classification
Classification-related information
Biodegradability: readily biodegradable (67.9 % biodegradation, OECD TG 301 D)
Partition coefficient: log Pow < 0.3 (OECD TG 117, HPLC method)
Ecotoxicological key results
Short-term (acute) toxicity
Fish: 96-hour LC50 > 5.6 mg/L (Danio rerio, OECD TG 203)
Aquatic invertebrates: 48-hour EC50 = 2.84 mg/L (Daphnia magna, OECD TG 202)
Aquatic algae: 72-hour ErC50 = 7.31 mg/L (Raphidocelis subcapitata, OECD TG 201)
Long-term (chronic) toxicity
Aquatic algae: 72-hour ErC10 = 1.70 mg/L (Raphidocelis subcapitata, OECD TG 201)
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 substance was determined to be readily biodegradable and its partition coefficient was measured to be < 0.3. The most sensitive aquatic species in short-term tests was Daphnia magna (48-hour EC50 = 2.84 mg/L). One long-term result based on grwoth rate is available for Raphidocelis subcapitata (72-hour ErC10 = 1.70 mg/L). Based on available data, the test item is neither classified and labelled 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 eighteenth time in Regulation (EU) 2022/692.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
