Key value for chemical safety assessment

Additional information

According to the Regulation (EC) No 1907/2006 (REACH) Annex VIII Column 2 a study on hydrolysis as a function of pH does not have to be conducted for substances highly insoluble in water. As the water solubility of Fatty acids, C18-unsaturated, trimers, hydrogenated is very low (< 0.001 mg/L), hydrolysis in water was not determined. Furthermore Fatty acids, C18 unsaturated, trimers, hydrogenated does not contain functional groups that are susceptible to hydrolysis and thus it is expected to be stable and not to hydrolyse under environmental conditions.
