Microemulsion –A Multidimensional Formulation

TL;DR: In this article , the authors reviewed the structure of microemulsion and their components like oil, surfactant, cosurfactant and water and discussed the multiple importance of micromulsion.

Abstract: ---------------------------------------------------------------------------------------------------------------------------------------ABSTRACT The trend of developing new formulation for drug delivery is growing worldwide due to introduction of new drugs as well as to solve problems of existing drugs. However, the formulation for lipophilic drugs needs much concern due to low aqueous solubility and bioavailability issues in oral route . Microemulsion plays an important role in drug delivery due to its ability to reduce interfacial tension between oil and water to a large extent as well its high solubilization ability. This paper reviews the structure of microemulsion and their components like oil, surfactant, cosurfactant and water. HLB value was considered for the selection criteria of surfactant that is the essential component of microemulsion. The method os preparation as well as characterization parameters were also discussed This review also discussed the multiple importance of micromulsion. The microemulsion formulation can be used for the different route of drug administration like parenetaral, oral etc.. This paper also described the application of microemulsion in cosmetic as well as washing applications.
