Description of key information

No biodegradation in water and sediment simulation test data are available. A ready biodegradation study showed the substance to be readily biodegradable; therefore, further biodegradation testing is not necessary.

Key value for chemical safety assessment

Additional information

The provision for biodegradation in water and sediment simulation testing is contained within Column 1 of Annex IX. Column 2 of this Annex, describing the Specific Rules for Adaptation from Column 1, states that such biodegradation testing is not required if the substance is readily biodegradable. A ready biodegradation screening study of the substance (see IUCLID Section 5.2.1) concluded it to be readily biodegradable. Therefore, in accordance with the Standard Information Requirements laid down by REACH (Annexes VII to X), further biodegradation testing is not necessary.
