Key value for chemical safety assessment

Additional information

In accordance with column 2 of Regulation (EC) No 1907/2006 Annex VIII, IX and X further biotic degradation tests shall be proposed if the result of the Chemical Safety Assessment indicates the need to investigate further the degradation of Fatty acids, C16-18 and C18-unsatd., hexaesters with dipentaerythritol (CAS 68604-38-6) and its degradation products. The substance is poorly biodegradable in water and therefore is likely to persist in the environment. Furthermore the substance is assessed to be neither acutely or chronically toxic nor to accumulate in organisms. Since the substance is not expected to cause an environmental risks further degradation studies are not proposed.
