Description of key information

Abiotic degradation is not relevant due to ready biodegradation.

Key value for chemical safety assessment

Additional information

No experimental studies investigating the abiotic hydrolysis of triacetin (CAS 102-76-1) 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 triacetin in the environment (DT50 129.97 d at pH 7; 13.0 d at pH8; Müller, 2013).
