Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
ASRIT: EC50 = > 100 mg/L NOEC = 100 mg/L
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 100 mg/L
Additional information
An activated sludge microbial growth inhibition assay has been undertaken following OECD/EU test methods.
BTN/A had no significant effect on the respiration rate of activated sludge. The EC50 could not therefore be calculated but must be greater than 100 mg/L, the highest concentration employed in the test.
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.
