The novel carriers have been exploited through almost all the routes of administration. Association of drugs with carriers is normally noncovalent, based on collective strength of weak binding forces. Many newer carriers are evolving with the advent of technology and the demand of targeted delivery like microemulsions. Microemulsions are clear, stable, isotropic mixtures of oil, water and surfa...

A combination of electrical conductivity, dynamic viscosity, dynamic light scattering and small angle X-ray scattering methods was used to study the properties of the water + propylene glycol/mixed nonionic surfactants/ peppermint oil + ethanol U-type microemulsions which can be diluted with any amount of water. The surfactants were sucrose laurate and ethoxylated mono-di-glyceride. The mixing ...

In this study, pseudoternare phase diagrams were made and oil: water: surfactant: cosurfactant (O:W:S:CoS) weight ratios corresponding to microemulsion states were highlighted. Soybean oil was used as the oily phase (O) and a mixture of water and glycerol in a ratio of 4:1 (wt / wt) was used as the aqueous phase (W). As a surfactant (S) was used sorbitan monooleate (Span 80) and cosurfactants (...
