The terms defoamer and anti-foam are often used interchangeably, but they are not the same. A defoamer destroys an existing stabi­lized foam at the air interface. On the other hand, an anti-foam prevents the formation of a stable foam. However, it is difficult to distinguish between their mechanisms, and quite often, commer­cial products generally perform both tasks. We will use the term defoamer in subsequent discussion.
