Additional information
Conclusion on classification
According to criteria of CLP regulation the substance is not classified.
Longterm results from three species representing three trophic levels are available. The lowest NOEC was obtained in a study with Daphnia (NOEC adult mortality, 21 days = 1.02 mg/L). NOEC values for fish and algae were >10 mg/L indicate a low chronic aquatic toxicity.
The substance is neither readily nor inherently biodegradable and the log Kow is -0.3. Therefore the substance is not classified according to CLP regulation.
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.
