Key value for chemical safety assessment

Additional information

The available data demonstrate that multi-constituent substance Tinuvin 292 does hydrolyse and is partially biodegradable. Therefore, Tinuvin 292 is not persistent in the environment and further biodegradation tests are not required. This is confirmed by the risk assessment performed for this substance. For all of the uses identified, safe use was demonstrated for all relevant compartments including water and sediments.
