Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The potential for biodegradation of diethanolamine has been investigated in a manometric respirometry test conducted according to OECD 301 F following GLP. Diethanolamine was determined to be readily biodegradable (according to OECD criteria) since the substance was degraded by 93 % after 28 days related to BOD. Activated sludge from a laboratory wastewater treatment plant treating domestic sewage was used as inoculum (BASF AG, 1992; report no. 1/91/1168/26/2).

In conclusion, diethanolamine is readily biodegradable (according to OECD criteria).
