A thin film ruptures when a fluid layer gets thinner than a critical thickness. In other literature, this critical thickness has been attempted to predict using the instability criteria for a wavy interface of the film. However, the predictions of those models deviate from experimental observations in the case of aqueous films at low surfactant concentrations. The discrepancy results from the hydrophobic force in the film, but the origin of the force has not been well understood yet. The force can be typically evaluated from film thinning kinetics data. On the other hand, there has been no model yet to incorporate it with the rupture. In this chapter, a model for predicting the critical rupture thickness has been derived by assuming that the hydrophobic force causes the instability of air-water film interfaces. As a result, the model could predict the rupture thickness and the time of rupture in the presence of the hydrophobic force.
