Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Additional information

There are no studies available for the substance itself. However, a valid studiy on a structural analogue substance (CAS 7023 -61 -2) is available.

The available study did not reveal any inhibitory effect in the highest tested concentration of 100 mg/L. Therefore, the NOEC was deteremined to be >= 100 mg/L which clearly exceeds the water solubility of the compound. Therefore, it can be assumed that the substance has no inhibitory potential of the degradation activity of activated sludge.
