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 isononanoic acid, C16-18 alkyl esters (CAS 111937-03-2) 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 readily biodegradable. Since isononanoic acid, C16-18 alkyl esters is readily biodegradable, 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 representative components of isononanoic acid, C16-18 alkyl esters in the environment (DT50 > 1 yr (pH 7); Müller, 2011).
