Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Chloramine B trihydrate is not intended for disinfection of soil and solid waste, but it is used in industrial, professional and private facilities. Hence a direct contamination of soil is unlikely.
Indirect contamination of the soil environment is unlikely, too, for the following reasons.
Chloramine B trihydrate is not biodegradable (see DOC IIIA However, 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.
As the substance – via fast dechlorination to its metabolite BSA – is readily biodegradable, further investigations with respect its fate and effects in soil ecosystems are obsolete.
