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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Degradation of the test substance was evaluated using two sets of models. The first set (i.e., Biowin 5 and 6) was used to estimate the potential for the test substance to biodegrade under aerobic conditions in a sewage treatment facility. The second set (i.e., Biowin 1 and 2) was used to estimate the test substance's potential to biodegrade under aerobic conditions, but not for a particular medium. Both sets of models predicted that the test substance would have a biodegradation half life under aerobic conditions of weeks to months.
Key value for chemical safety assessment
Additional information
In a weight-of-evidence approach based on information from biodegradation in aqueous media, DETDA is not expected to biodegrade in soil. This assumption is supported by Biowin 5 and Biowin 6 model estimations: DETDA would not readily biodegrade in the Japanese MITI (Ministry of International Trade and Industry) ready biodegradation test (i.e., OECD 301C). Biowin 1 and Biowin 2 models predicted that DETDA will not undergo rapid biodegradation under aerobic conditions.
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.
