Additional information
Conclusion on classification
Although the substance itself is rapidly degraded (via hydrolysis, photolysis and/or thermal decomposition) with an estimated half-life of 10 days the substance is not considered as rapidly degradable due to the findings in the screening tests for biodegradation as well as the simulation study in surface water.
Furthermore, adequate ecotoxicological information on the degradation products are not available. Based on the findings in the available information on the aquatic toxicity the substance is consequently classified as Aquatic Acute Cat.1 and Aquatic Chronic Cat. 1.
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.
