Description of key information

There are four reports available for this endpoint, with only one out of the four with a good quality EC10 i.e. the study with ethoxylated amines C16-18 saturated (CAS no 90367-28-5). For risk assessment purposes however will the EC10 of 15 mg/L as observed by Diefenbach be used despite the fact that the calculated EC10 is below the lowest test concentration applied.

Key value for chemical safety assessment

EC50 for microorganisms:
128 mg/L
EC10 or NOEC for microorganisms:
15 mg/L
