Accumulation of Surfactant in the Top Foam Layer Caused by Ruptured Foam Films

A. Introduction Foam science has been developed very systematically. Attention was paid to the structure, to the forces, to surface rheology, and to numerous sub-processes [1-5], however, stability remains the main target. The progress achieved in these analytical studies are the prerequisites for the elaboration of a model which would describe the stability of a foam as a whole.
