Surfactants: Role in Pharmaceutical Formulation

Surfactants are compounds that lower the Surface tension of a liquid, allowing easier spreading, and lowering the Interfacial tension between two liquids or between a liquid and Solid. Surfactants are amphiphilic in nature. Possessing both hydrophilic and lipophilic properties. Surfactants act as foaming agents, Emulsifiers and dispersants for Suspending Immiscible liquids or Solids, respectively, in water or Some other Liquid. The present review deal with suitable surfactants in different pharmaceutical doses form with their merits and demerits. The article also highlights Compatibility of Surfactants in different formulation with application of the Surfactants.
