Conclusion on classification
Classification related key information
Biodegradation:
The substance is readily biodegradable by OECD criteria (85.7 % biodegradation on day 28).
Partition coefficient:
Log Pow = -2.8 at 20 °C
Key information on aquatic toxicity
Aquatic acute toxicity
96 h, LC50 (Danio rerio): > 100 mg/L (nominal, OECD TG 203)
48 h, LC50 (Daphnia magna): > 100 mg/L (nominal, OECD TG 202)
72 h, EC50 (Raphidocelis subcapitata): > 100 mg/L (nominal, OECD TG 201)
Aquatic chronic toxicity
72 h, EC10 (Raphidocelis subcapitata): > 100 mg/L (nominal, 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 test substance was found to be readily biodegradable under the test conditions. The log Pow was determined to be -2.8. At the limit concentration of 100 mg/L no toxic effects towards fish, aquatic invertebrates and algae were observed. Hence, the 96-h LC50 (Danio rerio), the 72 -h EC10 and EC50 (growth rate; Raphidocelis subcapitata) and 48-h EC50 (Daphnia magna) were determined to be > 100 mg/L in nominal. Based on these results, the substance is neither classified for short term (acute) aquatic toxicity, nor classified for long term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP) as amended for the eleventh time in Commission Regulation (EU) 2018/669.
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.
