Foam Analysis

The importance of foam in a liquid and the requirements for it vary considerably depending on the application. Foam is a desirable feature in shower gels and shampoos, in detergents, in shaving creams, or in beverages such as beer; whereas in industrial processes, it often causes problems and must therefore be avoided. For this reason, the properties of foam—from its formation to its breakdown—are defined and tested during the product development phase.
