Description of key information

No degradation of the test item was observed after 28 days. The test item reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) is not readily biodegradable following ISO 14593:2005.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The ready biodegradation of reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) was tested according to ISO 14593:2005 under GLP. No significant degradation (14%) of the test item was observed after 28 days. Reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) is not readily biodegradable.
