Defoamers are used where foaming problems exist in aqueous systems. Foam control agents are effective in acidic or alkaline media, dispersible by dilution in cold or hot water with gentle agitation. They have low viscosity and spread rapidly on foamy surfaces. They have an affinity for the air-liquid surface, destabilizing the foam lamellae, which causes the rupture of the air bubbles and the disappearance of the foam.
