Description of key information

Hydrolysis is not relevant in regard to abiotic degradation in the environment (DT50 > 1 yr).

Key value for chemical safety assessment

Additional information

No experimental studies investigating the abiotic hydrolysis of isononyl isononanoate are available. However, in accordance with Annex VIII, column 2, of Regulation (EC) No 1907/2006, testing is not required since the substance is readily biodegradable. Due to the ready biodegradability of isononyl isononanoate, it is expected to be eliminated from the aquatic environment within a short period of time. In addition, a supporting QSAR calculation (HYDROWIN v2.00) indicates, that hydrolysis is a negligible pathway for the environmental fate of the components of isononyl isononanoate in the environment (DT50 > 1 yr (pH 7); Müller, 2012).
