Antifoam agents are agents which are themselves surface-active, accumulating at the interface between water and air (or more generally defined: between liquids and a gas). They thus greatly reduce the stability of the foam lamellae.
They are: esters of oleic and lauric acid with glycerol, ethylene glycol, sorbitol and polyethylene glycol derivatives (PEGs). Silicone-based antifoams have also proved to be effective.
