Additional information
Conclusion on classification
The environmental classification of the substance is currently not harmonized according to the CLP Regulation (EC) 1272/2008.
The L(E)C50 values determined in the key acute ecotoxicity tests were all determined to be > 100 mg/L. The substance is not readily biodegradable and its logKow is < 4. Based on available data the substance should not be classified for Acute toxicity.
As the NOEC for algae is > 1 mg/L (25 mg/L; no other long-term studies are available) the substance should not be classified for chronic toxicity either, following section 4.1.2.6 of the 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.
