In general, an effective defoamer must satisfy the following conditions:

Must have a higher surface activity than a foaming surfactant, i.e. it must have a lower surface tension.

Easy to disperse in a system

It must be insoluble (at least partially insoluble) in the foaming medium, or it will act as a surfactant itself, i.e. to stabilize the foam.

The droplet size of the defoamer should be within the thickness range of the foam thin layer.

Chemical inertia

No residue or odor
