Description of key information
Additional information
A reliable measured biodegradation study in water for KEL3587 is available and included in the dossier. Reliable studies on the biodegradation in sediment and soil are not available, however a waiver is justified for these endpoints.
A reliable (Klimisch 1) biodegradation study has been conducted for KEL3587 and is included in this dossier. The key study, Kronenberger et al (2007), determined that KEL3587 is readily biodegradable, based on 77% degradation in 28-days passing the 10-day window. Consequently this study will be taken for the biodegradation in water endpoint.
Waiver. In accordance with Column 2 of REACH Annex IX, the simulation test on ultimate degradation in surface water, the soil simulation test and the sediment simulation test (required in Sections 9.2.1.2, 9.2.1.3 and 9.2.1.4 respectively) do not need to be conducted as direct or indirect exposure of surface water, soil and sediment is unlikely as substance is readily biodegradable.In the environment, ready biodegradability means it can be assumed that KEL3587 will be biodegraded within the STP process and as a consequence a transfer to the terrestrial compartment via STP effluent is not expected. Furthermore, for substances not passing the STP-process but being readily biodegradable, it can be assumed that they will be also biologically degraded in the surface water within a short time.The chemical safety assessment does not indicate any need to investigate further the degradation of the substance and its degradation products. Also, the substance’s low log octanol-water partition coefficient (Log Kow) of<=- 0.46 at a neutral pH indicating low adsorptive potential. Therefore, no additional degradation testing is necessary based on unlikely exposure. Identification of degradation products (required in Section 9.2.3) is also not necessary.
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.
