Description of key information

The Biodegradation in water screening test demonstrated that, although the submission item did not meet the 10d-window criteria for being considered as “Ready Biodegradable”, there was substantial microbial metabolism of the submission item. Therefore, it is likely that the submission item also significantly degrades in sediment and soil. An experimental verification of this assumption is not deemed necessary.

Key value for chemical safety assessment
