Microemulsions are psuedohomogeneous mixtures which may show special performance towards reaction equilibria, nanoscale synthesis and reaction dynamics. Rate of reaction are most often accelerated in microemulsion media compared to that in water. This study is an effort to review some important reaction kinetics measured in reverse micro emulsion media. In the same time some pioneering research...

Microemulsion based cyclosporine has demonstrated better absorption with laser pharmacokinetic variability. For the clinical use of any new microemulsion based product, bioequivalence testing with existing formulation is necessary. Panimun Bioral (Test) and Sandimmun Neoral (Reference) were evaluated in different transplant centers using both volunteers as well as renal transplant patients. All...

The paper is focused on the formation of hydroxyapatite nanoparticles (HAp) in polyelectrolyte-modified microemulsions, in a microemulsion template phase consisting of cyclohexane, water, cationic surfactant and cosurfactant, in the presence of Na-polyacrylate (PAA) as an anionic polyelectrolyte. It is shown that PAA, can be incorporated into the individual inverse microemulsion droplets. The m...

We used microsecond time scale atomistic simulations to study the relaxation dynamics of the microemulsion water/octane/C(9)E(3) system. In order to determine what transport mechanism occurs under the conditions of surfactant excess, we studied the system under a wide range of temperatures (7-88 °C) and showed that the surfactant acts as an effective solvent for water and carries out passive wa...

There has been a continuously increased interest during recent years in the use of topical vehicle systems that can enhance drug penetration through the skin barrier into the skin or the systemic circulation. In particular, transdermal drug delivery (TDD) is an attractive alternative to conventional oral and injectable dosage forms. Since its introduction about twenty years ago, TDD has generat...

Mannosylerythritol lipid-A (MEL-A) is a glycolipid biosurfactant abundantly produced from soybean oil by microorganisms at a yield of up to 100 g/L. In this study, the formation of water-in-oil (W/O) microemulsion based on the single component of MEL-A was confirmed using dynamic light scattering (DLS) and freeze fracture electron microscopy (FF-EM). DLS and FF-EM measurements revealed that the...

Ž . Ultrafine lead titanate PbTiO powders in tetragonal form have been successfully prepared via two processing routes, 3 Ž . Ž . namely, conventional coprecipitation CPC and microemulsion-refined coprecipitation MCP . The formation process of lead titanate from the resulting precursors was monitored using techniques such as thermal analyses, FTIR spectroscopy, Raman scattering spectroscopy and...

Microemulsions prepared by using either sodium dodecyl sulfate (SDS) or trimethyltetradecylammonium bromide (TTAB) were tested with regard to the migration time, selectivity and number of theoretical plates using a set of both water-soluble and lipid-soluble vitamins. While in the separations where SDS was used as the surface-active agent for microemulsion preparation, better resolutions were o...

The enantiomeric separation of basic drugs was successfully demonstrated by using a novel chiral microemulsion electrokinetic chromatography (MEEKC). An interesting finding was that the chiral oil core ((S)-(+)-2-octanol) within the microemulsion droplets appeared to play an important role in the chiral separation mechanism. In addition, the enantioselectivity of the analyte-selector complex co...
