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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to Fig. 3.2 of the TNsG, long-term tests with earthworm or other soil non target organisms are required when there is an indication of risk for the terrestrial compartment based on the data for aquatic toxicity. The PEC/PNEC for the terrestrial compartment was calculated > 1 for all calculated scenarios.
Therefore, long term effects are not expected and consequently, reproduction tests with earthworms or other soil non-target organisms are not necessary.
Furthermore, Chloramine B trihydrate is not intended for direct use on soils, 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 7.1.1.2). 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.
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.
