Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
