Description of key information

Abiotic degradation is not relevant due to low water solubility.

Key value for chemical safety assessment

Additional information

No experimental studies investigating the abiotic hydrolysis of2,2-bis[[(1-oxoisononyl)oxy]methyl]-1,3-propanediyl diisononanoate(CAS 93803-89-5) are available. However, in accordance with Annex VIII, column 2, 9.2.2.1 of Regulation (EC) No 1907/2006, testing is not required since the substance is highly insoluble in water. The water solubility of the substance was determined to be below the detection limit (water solubility: < 0.05 mg/L) and therefore the hydrolysis study is probably technically not feasible due to the lack of suitable analytical methods. In addition, a supporting QSAR calculation (HYDROWIN v2.00) indicates, that hydrolysis is a negligible pathway for the environmental fate of2,2-bis[[(1-oxoisononyl)oxy]methyl]-1,3-propanediyl diisononanoatein the environment (DT50 (pH7) > 1 yr; Hopp, 2011).
