Description of key information

The substance is readily biodegradable.

Key value for chemical safety assessment

Additional information

According to Regulation (EC) 1907/2006, Annex IX, Section 9.2.1.2 and 9.2.1.4, Columns 2, a simulation study on ultimate degradation in surface water as welll as sediment simulation testing do not need to be conducted if the substance is readily biodegradable. Propylenediamine (CAS 78 -90 -0) is readily biodegradable (see IUCLID Ch. 5.2.1). Therefore, no simulation study will be provided.
