The influence of electric dipole moments of nonionic surfactants on inertia-dominated film thinning between two bubbles has been calculated. The repelling force due to dipole moments cannot be the cause of coalescence inhibition, as was suggested by G. Keitel and U. Onken, Chem. Eng. Sci. 37, 1635 (1982) and H. K. Tsao and D. L. Koch, Phys. Fluids A 6, 2591 (1994).
