Additional information

The key study is selected as the most recent study which was conducted according to a standard guideline method and GLP. The study indicates that the test substance is not toxic to waste water (activated sludge) bacteria at a loading rate of 100 mg/l.

A non-standard study is available (Evonik/Degussa). The result is Pseudomonas putida respiration inhibition EC10 1.4 ml/l.

An IC50 >2500 mg/l is reported in secondary literature (handbook, Chandra).
