The substance is not readily biodegradable
according to OECD criteria .
The ready biodegradability of the 1,1,3,3
-Tetramethylguanidine (CAS 80 -70 -6) was tested in an
GLP-biodegradability Closed Bottle test according to OECD 301D (Lonza
Ltd, Rep no.: 698 -301 -0729R, 2015). After an exposure of 28 days the
degree of biodegradation of the test substance was 5.2% based on
BOD/ThOD measurement. A domestic non-adapted activated sludge was used
as an inoculum. Therefore, 1,1,3,3-Tetramethylguanidine(CAS
is not readily biodegradable according to OECD criteria .
