Currently, the design of microemulsions is focussed on the formulation of environmentally compatible systems formed by non-harmful amphiphiles and oils. The use of sugar-based surfactants allows the design of microemulsions where, instead of the temperature, the addition of short- or medium-chain alcohols tunes the curvature of the amphiphilic interface. In this work, the resulting temperature ...

the use of an inorganic phase in water-in-oil (w/o) microemulsion has recently received considerable attention for preparing metal oxide nanoparticles. this is a technique, which allows preparation of ultrafine metal oxide nanoparticles within the size range 40 to 80 nm. preparation of nano chromium (iii) oxide studied investigated in the inverse microemulsion system. therefore the nucleation o...

Mixing two immiscible liquids (such as oil and water) using emulsifier and energy inputs has been the matter of study for decades. In early 1890’s extensive work have been carried out on macroemulsions (i.e. oil dispersed in water in the form of fine droplets or vice versa) (Becher, 1977) and several theories and methods of their formation have been vastly explored (Lissant 1976 and 1984). Howe...

microemulsion formulation of cyclosporin a (csa) in autoimmune hepatitis (aih)

in this work needle like hydroxy apatite were synthesized in a reverse microemulsion droplets of water in cyclohexane, separated by a cationic surfactant and co-surfactant, in the presence of na-polyacrylate (paa) as an anionic polyelectrolyte. characterization of the as formed hap nanoparticles at the room temperature were carried out by x-ray diffraction (xrd) and fourier transform infrared s...

the behavior of nanoscale energetic materials is quite different from micronsized energetic materials inmany ways. recently, some techniques such as sol-gel method, high speed air impaction and vacuum codeposition have been employed to obtain nanoscale energetic materials. however, only few attentionswere paid to nanoscale energetic materials because of the fabrication difficulty. in this paper...

the aim of this study was to develop a microemulsion system as a medium for laccase-catalyzed reactions. phase behavior studies were conducted by constructing partial pseudo-ternary phase diagrams for systems comprising of cetyltrimethylammonium bromide (ctab), various organic solvents as the oil phase (i.e., hexane, cyclohexane, heptane, octane, isooctane, toluene, isopropyl myristate), two co...

results the results showed that the maximum oil was incorporated in microemulsion system that contained surfactant to cosurfactant ratio of 4:1. the mean droplet size range of microemulsion formulation was in the range of 5.09 to 159 nm, and its refractory index (ri) and ph were 1.44 and 7, respectively. viscosity range was 57-226 cps. drug release profile showed that 48.18% of the drug release...

the available minoxidil formulations for topical application suffer with major drawback having less contact time with the scalp which requires repeated application. hence, the present study was aimed to investigate the effect of microemulsions and microemulsion based hydrogel systems (mehs) for increased percutaneous penetration of minoxidil. minoxidil microemulsions were developed by following...
