The dynamic maximum-bubble-pressure method was used to measure the dynamic surface tension of Triton X-100 solutions (at the CMC and at concentrations above the CMC). Measurements were performed at 30.0, 40.0, 50.0, and 60.0-degrees-C. The results at 30.0-degrees-C are in excellent agreement with the data obtained through other methods (oscillating jet and inclined plate). The demicellization rate constant is obtained according to a method previously described. It is found that this demicellization rate constant depends strongly on the surfactant concentration, in agreement with a previous investigation, using oscillating jet and inclined plate techniques. It is also found that this rate constant is nearly independent of the temperature, pointing to an entropic effect.
