Kinetics of aerobic oxidation of ascorbic acid in the presence of nonionic surfactants.

The effect of two nonionic surfactants, poloxalkol and polysorbate 80, on the aerobic oxidation of ascorbic acid was studied at 67° and pH 4.55 and 6.60. Results show a relationship between surfactant concentration and oxidation rate, the rate increasing at surfactant concentrations well below the surfactant's CMC and decreasing as the surfactant concentration approaches its CMC. The thermodynamic parameters were obtained for ascorbic acid solutions containing 1% surfactant.
