How do defoamers work?

How do defoamers work?

In general, a defoamer is a product that is not soluble in a foaming media and has surface acting properties.  

Some defoamers with very low viscosities spread rapidly on liquids with foamy surfaces.  They destabilize foam and cause bubbles to rupture on the surface of the liquid.

Some defoamers reduce the viscosity and elasticity of the liquid surface by destroying the structures that hold the foam bubbles together.  Insoluble substances cause a reduction in foam elasticity and cause the bubbles to pop.

Still other defoamers form monolayers on a liquid surface that replace foam stabilizing surfactants.  They reduce surface tension and stop foam growth.
