Description of key information

Ready biodegradability (Manometric Respirometry) 91 % biodegradation after 28 d. (440 g/mol average molecular weight)

Inherent biodegradability results ranged between 20 and 66% in 28 days for 440 - 720 g/mol average molecular weight.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Biodegradation in water was tested in four screening studies, according to EU C.4-D ("ready biodegradability") Manometric Respirometry test and 302B (inherent biodegradability) and Environmental Science Research Test Methods from The Dow Chemical company. Ready biodegradability results showed 91 % biodegradation in 28 days for a test material with 440 g/mol average molecular weight. Inherent biodegradability results ranged between 20 and 66% in 28 days for 420 - 720 g/mol average molecular weight.
