ABSTRACT
The stability and breaking of a foam is a subject of great importance because foams occur both as a desirable product and as an undesirable entity in many industrial processes, such as firefighting, froth flotation, foam fractionation, food products (cream, sponges), personal care products, foamed latex, expanded poly mers, and so forth. In all these applications, stable foams of varying degrees are necessary [1-7]. Foams can also be undesirable in many industrial processes. Examples are their occurrence in the refining of crude oil, sugar processing, steel production, paper manufacturing, and so forth [8-13].
