Description of key information
Additional information
Regarding the environmental fate and pathways there are only few data available. The substance has a high reactivity towards OH radicals in the atmosphere and hydrolyses rapidly, but it is not readily biodegradable in aqueous systems. As no biodegradation (0%) was observed in a study on ready biodegradability, it is not expected that a significant degradation would occur in a simulation test. The test substance is considered as non-biodegradable in surface water and sediment compartment. Moreover, biodegradation is irrelevant as primary degradation step because immediate hydrolysis takes place. Due to the rapid hydrolysis, the determination of bioaccumulation in aquatic systems is not possible.
Furthermore it is not necessary to determine the adsorption/desorption potential since the substance hydrolyses rapidly. Under the test conditions required for covering this endpoint, the primary degradation product will react further. Therefore its adsorption / desorption also cannot be measured. Quantifying the adsorption / desorption of the resulting polymer is technically not feasible because of its inhomogeneous composition, its low mobility inhibiting equilibration, and analytical limitations.
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.
