What is a surfactant? What are the types that can be classified according to their water dissociation properties?
Surfactants are a type of chemical substance that can reduce surface or interfacial tension. They can gather on the interface in water or other solutions, change the characteristics of liquid-liquid or liquid-solid interface, and make it show good wetting, dispersion, emulsification, foam stability and other properties. According to the dissociation properties of surfactants in water,…
