Description of key information
Additional information
The substance is readily biodegradable and no hazard was identified for aquatic organisms (acute and long-term studies available in fish, aquatic invertebrates and algae). One short-term toxicity test on a soil macroorganism (nematods) is available in which the low toxicity was confirmed (LC50 =7960 mg/kg soil dw). This study was conducted according to ASTM E2172-01 guideline (2001). It was considered valid and used for PNECsoil derivation in accordance with the Guidance on information requirements and chemical safety assessment Chapter R.10: Characterisation of dose [concentration]-response for environment, and used in the risk assessment.
The chemical safety assessment indicates that the risks in the soil are controlled (PNEC/PEC < 1). Therefore, at this stage, in accordance with the Guidance on Information Requirements and Chemical Safety Assessment Chapter R.7c: Endpoint specific guidance and based on the available information on aquatic organisms and nematods indicating very low toxicity, long-term studies on the effects of the substance on soil macroorganisms except arthropods, terrestrial plants and soil microorganisms are waived.
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.
