Description of key information

The inhibition of the degradation activity of activated sludge is not anticipated when 2-ethyl-N,N-bis(2-ethylhexyl)hexylamine is introduced in appropriate low concentrations.

Key value for chemical safety assessment

Additional information

The toxicity to microorganisms was determined in a GLP short-term respiration test similar to OECD guideline 209 using domestic activated sludge. After 180 min the EC10 was 970 mg/L based on nominal concentrations (BASF, 2010). An inhibition of the activity of microorganisms in wastewater treatment plants is not expected up to the maximum water solubility.
