Conclusion on classification
Aquatic acute toxicity
48 h, EC50 (Daphnia magna): 74 mg/L (nominal)
72 h, ErC50 (Pseudokirchneriella subcapitata): > 74 mg/L (nominal)
96 h, LC50 (Onchorhychus mykiss): 1020 mg/L (nominal)
Aquatic chronic toxicity
72 h, NOEC (Pseudokirchneriella subcapitata): => 74 mg/L (mean measured, TWA)
Biodegradation: Readily biodegradable in a ten day window and after 28 days (99% degradation within 28 days)
Partition coefficient: Log Pow < -4.2 at 21.9 °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 most sensitive test for the aquatic compartment was the toxicity test to aquatic invertebrates (Daphnia magna). The test revealed a 72-h EC50 of 74 mg/L. The substance is readily biodegradable (99% degradation within 28 days) and has a log Pow below -4.2 at 21.9 °C. 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.
