Active ingredients           
Function: breaking and defoaming, reducing surface tension:           
Representatives: silicone oil, polyether, higher alcohol, mineral oil, vegetable oil, etc.           
Emulsifier           
Function: make the active ingredients disperse into small particles, easy to disperse in the water, and play a better role in defoaming and antifoaming.           
Representative products: nonoxyphenol polyoxyethylene ether, soap salt, Op series, Tween series, Sipan series, etc.           
carrier           
Function: it is conducive to the combination of carrier and foaming system, and easy to disperse into the foaming system. When the two are combined, its own surface tension is low, which is conducive to foam suppression, and can reduce the cost.           
Representative: solvent other than water, such as aliphatic hydrocarbon, aromatic hydrocarbon, oxygenated solvent, etc           
Emulsifying agent           
Function: better emulsification effect.           
Representative: dispersant (hydrophobic silica, etc.); tackifier: (CMC, polyethylene ether, etc.).
