Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Bioconcentration and bioaccumulation in aquatic organisms is not expected since the log Kow value of Chloramine B trihydrate is < 3 (0.14). Furthermore contamination of the aquatic environment is unlikely for the following reason: Though Chloramine B trihydrate is not biodegradable (see DOC IIIA 7.1.1.2), experiments showed that during its application and its discharge in wastewaters, complete degradation occurs by fast dechlorination (see DOC III-A_7.3.3_1 and DOC III-A_7.3.3_2), The dechlorinated form of Chloramine B, benzenesulphonamide (BSA), is readily biodegradable (see DOC IVA / A29 and A30). Hence at the proposed use concentrations, chloramine B trihydrate degrades completely and does not enter the environment. Therefore, no further tests for fish and aquatic invertebrates are being proposed.
Key value for chemical safety assessment
Additional information
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.
