Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The available studies show that DCBS is not readily biodegradable. It was suggested that the lack of biodegradation is due to the high concentrations used in those tests (100 mg/L) which is high above the water solublity of 1 -5 µg/L. Therefore, inherent tests with lowered concentrations (10 mg/L, 67 µg/L) were performed. However due to shortcomings in the analysis of the parent and degradation products the mass balance at the start of the study was not confirmed.
A simulation study in soil finally showed DCBS to be rather stable in soil. During the study period of 120 days DCBS declined to 75 to 87% of its original concentration resulting in half-lives of 315 to 615 days at 12°C.
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.
