Application of surfactants in the pharmaceutical field

Surfactants have functions such as wetting, emulsifying, and solubilizing, and are therefore widely used as excipients for pharmaceutical preparations. They are especially used more and more widely in the pharmaceutical microemulsion technology developed in recent years. In drug synthesis, surfactants can be used as phase transfer catalysts, which can change the solvation degree of ions, thereby increasing the reactivity of ions, allowing the reaction to proceed in a heterogeneous system, greatly improving the reaction efficiency, and drug In analysis, especially in drug fluorescence spectrometry, surfactants are often used as solubilizing and sensitizing agents. In the pharmaceutical industry, for preoperative skin disinfection, wound or mucous membrane disinfection, instrument disinfection and environmental disinfection, surfactants can be used as bactericides and disinfectants because they can strongly interact with bacterial biofilm proteins, causing them to denature or lose their function. being widely used.
