Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

 According to Regulation (EC) No. 1907/2006, Annex IX, simulation testing on biodegradation in soil should be provided as part of the information requirements for REACh. Simulation testing on biodegradation in soil is relevant for those substances showing high adsorption potential (Annex IX, Column 1, 9.2.1.4). Based on the Koc values a low adsorption potential of the reaction mass can be expected. Furthermore, the results of an inherent biodegradation test, showed 84% degradation after 28 days of exposure. This value indicates that the substance can be ultimately biodegraded under environmental conditions. Based on the information above, simulation testing on biodegradation of the substance in soil is not deemed necessary.

Nevertheless, one non-standard biodegradation test for the reaction mass in soil is available (Nitsche, 2012). In this supporting study, 20 mg/L test substance was added to a certified universal standard soil (LUFA, Germany). With HPLC-analyses a half-live of 10.4 hours was determined for the reaction mass.
