Key value for chemical safety assessment
Additional information
In Annex IX, column II (9.1) of Regulation (EC) No 1907/2006, it is laid down that a long-term toxicity test shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on aquatic invertebrates. The hazard assessment of Reaction product of fatty acids C14-18/C16-18 unsaturated with dihydrogendioxide and ammonia reveals that aquatic invertebrates are the most sensitive organisms. However, the 48h-EC50 is measured to be > 10 mg/L indicating that the substance is not acute toxic but harmful to aquatic invertebrates. Given the very fast biodegradation of the substance in the environment (> 50% in 5 days /~ 80% in 15 days) and the very low bioaccumulation potential (log Kow = 1.48) chronic toxicity of the substance is not indicated. In addition, an exposure assessment and a subsequent risk characterisation performed using PNECs derived on the basis of the available aquatic short-term toxicity tests (EPM; including a conservative assessment factor of 1000) indicate no risk for the aquatic environment. Therefore, a long-term toxicity test in aquatic invertebrates is not provided.
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.
