Description of key information

Hydrolysis is not considered to be a relevant abiotic degradation process.

Key value for chemical safety assessment

Additional information

No experimental studies investigating the abiotic hydrolysis of 1,3-butylene diacetate (CAS 1117-31-3) 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. In addition, a supporting QSAR calculation (HYDROWIN v2.00) indicates, that hydrolysis is a negligible pathway for the environmental fate of 1,3-butylene diacetate in the environment (DT50 > 1 yr (pH 7); Müller, 2011).
