The basic role of Surfactants
Surfactants are amphiphilic molecules that enable them to have two interfacial (surface) adsorption functions in aqueous solutions. First, the surface tension of water can be rapidly reduced through "positive adsorption", reflecting the wetting and penetrating effects of surfactants; Second, through "micellarization", a large number of micelles can be formed in water and the interfacial tension between the two phases can be effectively reduced, so that liquids, solids, and gases can exist stably in water, which reflects the emulsification, dispersion, foaming, and emulsification of surfactants. Solubilization, etc. The washing action is a comprehensive process in which the surfactant exerts various functions such as wetting, emulsifying, dispersing, foaming, and solubilizing. Below, we briefly discuss the wetting, emulsifying, dispersing, foaming, solubilizing, washing and ot...
