Additional information

Abiotic degradation of Fatty acids, C18 unsaturated, trimers, 2-ethylhexyl esters (CAS No. 173832-46-7) is not a relevant pathway. Since the substance is not likely to be present in the atmosphere (vapor pressure < 0.0001 Pa), indirect photodegradation in air will not occur to a significant degree. Abiotic hydrolysis is not relevant, since the substance is poorly soluble in water. Additionally, the estimated half-lives for hydrolysis calculated for representative components are > 1 yr).
