The results of vitamin C atmospheric oxidation in the N-oxide surfactant solutions obtained by UV-Vis spectroscopy are presented. As follows from our studies, in the solutions containing N-oxides vitamin C undergoes atmospheric oxidation more readily than in pure water and the rate of oxidation increases with the increasing surfactant concentration. The stabilizing effect of high surfactant concentration on vitamin C was not observed as it was the case of ionic surfactants: SDS and CTAB. (C) 2012 Elsevier By. All rights reserved.
