Description of key information

BisP-IOTD is designated as not readily biodegradable in a test according ot OECD 301D.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The relative biodegradation values calculated from the O2 measurements performed during the test period of 28 days revealed no signficant biodegradation of BisP-IOTD at both concentrations.

In the toxicity control, BisP-IOTD was found not to inhibit microbial activity.

Since all criteria for acceptability of the test were met, this study was considered to be valid.

In conclusion, BisP-IOTD is designated as not readily biodegradable.
