Surfactant is one of the main components in soap making. When air bubbles are blown into the surfactant, foam will form. And within a certain time, the foam will disappear. One of the factors that affect how quickly the foam dissipates is the size of the bubble being blown. Some studies show that the foam can last longer if the air bubbles are blown smaller. Small air bubbles have a smaller surface area to volume ratio, making them more stable and not easily broken. As a result, the foam that is formed can also last longer.

The study of foam stability is one of the research focuses at the Nano Center Indonesia. The bubbles used are in the nanoscale, so the stability of the resulting foam is very high. Research on high stability foam can be applied to oil and gas mining to push petroleum out.
