Additional information
Conclusion on classification
The substance is not been shown to be rapidly biodegradable, and has an aquatic toxicity of 2.2 mg/L (i.e., the 21 -day NOEC in Daphnia magna), indicative of an aquatic hazard chronic classification of Category Chronic 3, in accordance with the GHS classification in Regulation EC No. 1272/2008. Therefore, the substance is assigned the hazard statement "H412: Harmful to aquatic life with long-lasting effects", Precautionary statement prevention P273 and Precautionary statement disposal P501. This determination is not sufficient to show rapid degradation, in the absence of information regarding the classification of the degradation products in accordance with Section R.7.9.5 ofGuidance on information requirements and chemical safety assessment: Chapter R.7b: Endpoint-specific guidance (ECHA, May 2008, pp. 182-187).
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.
