Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The NOEC for soil microorganisms can be set to 3 mg/kg soil dw of Chloramine T, this is equivalent to 2.3 mg/kg soil dw o-TSA.
Key value for chemical safety assessment
- Long-term EC10 or NOEC for soil microorganisms:
- 2.3 mg/kg soil dw
Additional information
No studies are available on this substance but one study is available on Chloramine T which is instantly converted to p-TSA in contact with organic material. p-TSA shows similar toxicity to organisms as o-TSA, therefore this study can be used here as well.
One study, valid with restrictions, is available for terrestrial microorganisms with Chloramine T (CAS 127 -65 -1). Natural soils with an organic carbon content of 0.58%, were exposed to 3 mg/kg soil dw in a 28d study according to OECD guideline 216, in which stimulation of nitrogen mineralization or no effect was found, therefore the NOEC can be set to 3 mg/kg soil dw of Chloramine T, this is equivalent to 2.3 mg/kg soil dw o-TSA.
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.
