Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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).
