Description of key information


Key value for chemical safety assessment

Additional information

Based on the REACH Regulation, (Annex IX, specific rules for adaptation from Column 1) further biotic degradation testing shall be proposed only if the Chemical Safety Assessment according to Annex I indicates the need to investigate further degradation of the substance and its degradation products.

Based on the Chemical Safety Assessment the exposure of water and sediment will be negligible, since the substance is used in closed systems at 100 %. Plants are provided by internal recycle systems and all production residues are re-used. No dispersive use is reported.

No further tests on biodegradation on water and sediments are proposed.
