Description of key information

Hydrolysis is not relevant in regard to abiotic degradation in the environment (DT50 > 24 h). 

Key value for chemical safety assessment

Additional information

No experimental studies investigating the abiotic hydrolysis of 1,2,3-Propanetriol, homopolymer, diisooctadecanoate (CAS 63705-03-3) are available. However, in accordance with Annex VIII, column 2, 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 1,2,3-Propanetriol, homopolymer, diisooctadecanoate (DT50 = 96.13 d – 1.41 yr at pH 8; DT50 = 2.63 yr – 14.15 yr at pH 7; Hopp 2011, Marwitz 2012).
