Ghana What are the advantages of Free of silicone defoamers for water-based cleaning agents(3)
A substance that can reduce the surface tension of water, solution, suspension, etc., prevent the formation of foam, or reduce or eliminate the original foam. 
Defoaming agents should have the following properties: ① strong defoaming power and low dosage; ② Adding to the foaming system does not affect the basic properties of the system, i.e. does not react with the defoaming system; ③ Low surface tension; ④ Good balance with the surface; ⑤ Good heat resistance; ⑥ Good diffusion and permeability, high positive spreading coefficient; ⑦ Chemical stability, strong oxidation resistance; ⑧ Good gas solubility and permeability; ⑨ Low solubility in foaming solutions; ⑩ No physiological activity, high safety
Many people often have concerns when choosing to add water-based defoamers in the production of cleaning agents. Do water-based defoamers affect the viscosity, transparency, and performance of cleaning agents. In fact, the detergent that plays a decontamination role is a surfactant. When the surfactant is dissolved in water, it removes dirt by emulsifying, dispersing, and solubilizing oil. Therefore, the decontamination ability of the detergent is not necessarily related to its viscosity and transparency, so the water-based defoamer does not affect its viscosity and transparency. The decontamination ability of cleaning agents is mainly related to the formula, that is, surfactants, such as anionic surfactants, have more foam than non-ionic surfactants. On the contrary, the defoamer of water-based cleaning agent can also reduce the production of foam and make foam disappear where it should not be, thus greatly improving the effect of cleaning agent.
