DETERGENT-FOAM - generation, regulation, destruction ? testing and evaluation

Foam plays an important role in many processes, both in industry and in the home. Sometimes foam is desirable and, indeed, a typical product characteristic; examples are shampoo and the head on beer. Often foam makes an important contribution to product performance, for example in washing and cleaning. On the other hand, in textile and paper manufacture, for example, foam disrupts the process and must therefore be prevented. So depending on the application, foam must be specifically produced, regulated or destroyed and its properties fitted to the specific requirements. In many areas where surface activity plays a role, this opens possibilities for improved products and processes. Such developments require a basic understanding of the physical and molecular processes of foam formation and behaviour, a well as the ability to use laboratory methods for a realistic study of practical applications. The choice of appropriate test methods is of considerable importance
