Description of key information

The biodegradability of Cyclohexane, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethyl-, homopolymer, caprolactam-blocked was examined in a "Manometric Respirometry Test"-test according to EU-Method C.4 -D and OECD 301 F (IBACON GmbH 2001). Oxygen consumption was measured continuously (at least daily) over a period of 28 days. Cyclohexane, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethyl-, homopolymer, caprolactam-blocked was observed to be "not readily biodegradable" under the present test conditions (1% biodegradation within 28 days). 

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed
