readily biodegradable

Additional information

N,N'-bis(3-aminopropyl)ethylenediamine was tested in a GLP guideline study following OECD 301B (CO2 Evolution Test; enhanced test period). The substance was degraded by 70% after 28 days and by 81% after 60 days (based on CO2/ThCO2). The 10 -days window was met. Hence, the substance is readily biodegradable according to OECD criteria (BMG, 2012; BASF report No. 22G0402/04X047).

This result is supported by a biodegradation study performed in activated sludge units conducted similar to OECD 303 A. Based on TOC removal, the substance was degraded by 85% after 42 days (Popp, 1977).
