Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 550 mg/L
Additional information
The effect of 2,6 -xylidine (CAS 87 -62 -7) was studied in a short-term respiration test using domestic activated sludge as inoculum. The non-GLP study was performed according to OECD 209. The 30 -min EC20 value was determined to be ca. 150 mg/L, teh 30 -min EC50 was ca. 550 mg/L (nominal; OECD 209, BASF AG, 1992, rep. no.: 92/2467/08/1).
Therefore, it can be concluded, that the inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations.
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).
