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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
Description of key information
No simulation tests on the biodegradation of the test substance in water and sediments are deemed necessary.
Key value for chemical safety assessment
Additional information
In accordance with Regulation (EC) No 1907/2006, Annex IX, Section 9.2 and 9.2.1.2, Column 2, the simulation test on ultimate degradation in surface water does not need to be conducted as the chemical safety assessment according to Annex I indicates that there is no need to investigate further the degradation of the substance and its degradation products. In addition, due to the results of the available tests on ready biodegradability, 1,4-dioxane is considered as poorly biodegradable. Further testing on biodegradation in water would not add further information and is therefore 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.
