Description of key information

Hydrolysis is not expected to be a relevant degradation pathway for Fatty acids, C16-18 and C18-unsatd, hexaesters with dipentaerythritol.

Key value for chemical safety assessment

Additional information

No experimental studies investigating the abiotic hydrolysis of Fatty acids, C16-18 and C18-unsatd., hexaesters with dipentaerythritol (CAS 68604-38-6) are available. The substance is characterised by a low water solubility (<0.15 mg/L; Frischmann, 2012). In accordance with column 2 of Annex VIII 9.2.2.1 of EC 1907/2006 testing of hydrolysis as a function of pH is not required because the substance is highly insoluble in water. Calculated half-lives for the substance components (DT50 [pH7] > 1 yr) indicate that abiotic degradation by hydrolysis is not relevant regarding the environmental fate of the substance (HYDROWIN v2.00, Blum 2011).
