Not relevant due to ready biodegradation

Key value for chemical safety assessment

Additional information

No experimental data evaluating the hydrolysis of 2,3-dihydroxypropyl laurate (CAS No. 142-18-7) are available. However, according to Regulation (EC) No. 1907/2006, Annex VIII, column 2,, testing for hydrolysis is not required since the substance is readily biodegradable. The results from the supporting QSAR calculations performed with HYDROWIN v2.00 indicate that indeed hydrolysis is not expected to be a relevant degradation pathway for this substance, with half-lives of 7.7 years (pH 7) and 282 days (pH 8)(López Parrón, 2011).
