The substance is inherently biodegradable since significant mineralization of 57% was found within 60 days under conditions of a ready biodegradation study.
Two valid GLP studies show that the substance is not readily
biodegradable. This is the case for exposure to activated sludge (key
study) and to sewage (supporting study). Both studies detected
biodegradation at a low extent (maximum 10.4% and 13% within 28 days of
exposure). The key study (which had been conducted with activated
sludge) demonstrated maximum 13% biodegradation within 28 days in one
replicate, plateau not reached yet. The 10% trigger value was reached on
day 25. Furthermore, prolongation of the study to 60 days showed
biodegradation of 57%. Based on the potential for biodegradation, the
substance is considered to be inherently biodegradable.
