Defoamers are used in a wide variety of industries. They function both as antifoamers, to prevent build-up of foam, and as defoamers to destroy foams which have already formed. They are also used as de-aerating agents to accelerate the escape of entrapped air. The term "defoamer" is used to cover materials which have either antifoaming or defoaming efficiency or both. When used in "antifoaming", i.e. to prevent foam formation, the defoamer is added to the liquid which is liable to foam before any foam formation takes place. The efficiency of a defoamer in this context is measured by its effectiveness in preventing or minimising foam formation.

The term "defoaming" refers to the ability of a defoamer which shows good antifoaming activity may be expected to show also good defoaming activity, this is by no means always the case.
