For the quantitative estimation of yellowing due to the oxidation of oily soils, and their detergency, the autoxidation and yellowing of linoleic acid in the bulk phase were investigated by UV spectroscopy. The oxidized products were quantitatively separated by the TLC-FID method.
UV spectroscopy showed oxidation to occur more rapidly when more oxygen was present, and to be inhibited by the radical scavenger, galvinoxyl. A quantitative determination of oxidized products was possible by the TLC-FID method. A good linear relationship was observed between amounts of oxidized products and integral intensities of the UV spectra at 235 nm and 270 nm.
