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).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
