The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations.
As key study a GLP test according to OECD 209 was performed with modified Isophoronediamine (BASF AG 2005, report no. 08G0405/053154). As inoculum actived sludge from a municipal wastewater plant in Mannheim/Germany was used, the pH of the test solutions was adjusted. The EC20 after 180 min was determined to be 450 mg/L (BASF AG, 2005). The test is valid according to OECD criteria.
