Conclusion on classification
Degradation
Biodegradation: Not readily biodegradable: 0% after 28 d (O2 consumption, EU Method C.4-E)

Fish: 96 h, LC50 (Danio rerio): 42.4 mg/L (nominal)
Aquatic invertebrates: 48 h, EC50 (Daphnia magna): 52 mg/L (measured, geometric mean)
Algae: 72 h, ErC50 (Pseudokirchneriella subcapitata): 115 mg/L (nominal)
Aquatic chronic toxicity
Fish: no data available
Aquatic invertebrates: no data available
Algae: 72 h, ErC10 (Pseudokirchneriella subcapitata): 43.3 mg/L (nominal)
Classification according to CLP
Acute toxicity data are available for all three trophic levels whereas chronic data are only available for algae. The test substance is not considered to be rapidly degradable and has a low potential for bioaccumulation (log Kow < 4). Fish was found to be the most sensitive species with a LC50 (96 h) of 42.4 mg/L. Thus, the test substance needs to be classified and labeled as “chronic category 3” (H412) according to the 9th ATP of Regulation (EC) No 2015/1221 (CLP).
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.
