Active ingredients and carrier structure of defoaming agents

(1) Active ingredients

Function: Breaking and defoaming, reducing surface tension:

Representative substances: silicone oil, polyethers, higher alcohols, etc.

(2) Emulsifier

Function: Disperse the active ingredients into small particles, which are easy to disperse in water and have better defoaming and anti-foaming effects.

Representative substances: non(octyl)phenol polyoxyethylene ether, soap salt, op series, etc., Tween series, Span series, etc.

(3) Carrier

Function: It helps to combine the carrier and the foaming system, and is easy to disperse into the foaming system. Combining the two has low surface tension, helps suppress foaming, and can reduce costs.

Representative substances: solvents other than water, such as aliphatic hydrocarbons, aromatic hydrocarbons, oxygen-containing solvents, etc.

(4) Emulsifying additives

Function: Make the emulsification effect better.

Representative substances: dispersant: hydrophobic silica, etc.; tackifier: CMC, polyvinyl ether, etc.
