Defoamer - Wikipedia

Properties. Generally a defoamer is insoluble in the foaming medium and has surface active properties. An essential feature of a defoamer product is a low viscosity and a facility to spread rapidly on foamy surfaces. It has affinity to the air-liquid surface where it destabilizes the foam lamellas.This causes rupture of the air bubbles and breakdown of surface foam.
