Molecular formula :
nature : can significantly reduce the interfacial tension of the material. Its molecular structure is with hydrophilic and hydrophobic parts components. As part of hydrophilic hydrophilic based or oil-based dredging, or by ion polar group composition; As part of hydrophobic oil-based or water-repellent - is usually straight-chain, branched chain or belt aryl hydrocarbon composition. For example, 60 ° C water to the surface tension 66.233mN / m, add the surfactant sodium salt dodecanol, the concentration of 0.0156mol / L, the surface tension of water dropped to 30.40mN / m. Many types, and can be divided into cationic, anionic and non-ionic, in addition to amphoteric surfactants. A wide range of uses. Commonly used for detergents, wetting agent, emulsifier, dispersant, foaming agent, demulsifier and penetrant, Defoamer, flotation agent, softener, waterproofing agents, antistatic agents agents. Cationic surfactants have excellent bactericidal effect can be used as a fungicide.
