Additional information
Conclusion on classification according to CLP Regulation (EC) no. 1272/2008:
Based on available acute tocxicity tests performed on alga and daphnia magna the test substance does not need to be classified for acute toxicity. Also, based on chronic toxicity data available for alga the test substance does not need to be classified either. However, a value of L(E)C50 between 1 -10 mg/L has been obtained from the acute tocicity test on daphnia and hence the substance is classified for chronic aquatic toxicity category 2, H411, since it was determined to be not readily biodegradable.
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.
