Description of key information

The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
10 000 mg/L

Additional information

No data on the toxicity of the test substance to microorganisms are currently available. In a guideline study according to DIN 384 12, Part 27, which was conducted with the structurally similar substance CAS 102242 -49 -9, an EC0 (30 min) of 10000 mg/L was determined (Henkel R 0800124, 1988). Hence, the inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
