Description of key information

Hydrolysis is not considered to be a relevant degradation pathway.

Key value for chemical safety assessment

Additional information

No experimental study is available forfatty acids, tall-oil, triesters with trimethylolpropane (CAS 94581-09-6) investigating the abiotic hydrolysis. In accordance with Regulation (EC) No 1907/2006, Annex VIII, column 2, 9.2.2.1 the testing of abiotic hydrolysis is not required as the substance is readily biodegradable. However, hydrolysis rates for the main components of fatty acids, tall-oil, triesters with trimethylolpropane were calculated using HYDROWIN v2.00 (Müller, 2014). The results show that the abiotic hydrolysis is not a relevant degradation pathway (7.77 - 23.31 yr at pH 7; 283.8 d - 2.33 yr at pH 8).
