Pure liquids, free of surfactants do not foam.

Foam is a state of a higher energy level (dispersion of a gas in a liquid). Therefore

foam is only stable in systems containing surface active substances (eg. surfactants).

Theory

What is foam?

10

Theory

Definitions

The term “Foam Control Agent” (FCA) is a collective name for:

1. Antifoams are used to prevent foam formation.

2. Defoamers are added to destroy existing foam at the surface.

3. Air release agents remove (micro) air bubbles from the liquid and

help them to rise to the surface.

Often the differences between these terms are not obvious or unclear. Therefore it is

important to understand the requirements and the application.
