The objective was to develop an elemene oil/water (o/w) microemulsion and evaluate its characteristics and oral relative bioavailability in rats. Elemene was used as the oil phase and drug, polysorbate 80 as a surfactant along with ethanol, propylene glycol, and glycerol as the cosurfactants. The microemulsion was prepared by mixing method, or ultrasonication method in an ultrasonic bath. Its t...

Use of microemulsion in enhanced oil recovery has become more attractive in recent years because of its high level of extraction efficiency. Experimental investigations have been made on characterization of microemulsions of oil-brinesurfactant/cosurfactant system for its use in enhanced oil recovery (EOR). Sodium dodecyl sulfate, propan-1-ol and heptane were selected as surfactant, cosurfactan...

The aim of this study is to develop a microemulsion product from a plant essential oil having the highest anti-tyrosinase activity. The in vitro anti-tyrosinase activity of six essential oils extracted from six edible plants was compared. The oil of Cymbopogon citratus demonstrated the highest activity which was significantly nontoxic to normal human cells. The GC-MS data indicated that gerania...

Pd–Co–Au/C catalysts synthesized by the conventional borohydride reduction method and reverse microemulsion method followed by heat treatment at 500–900 C in a reducing atmosphere have been characterized by X-ray diffraction, transmission electron microscopy, and polarization measurements for oxygen reduction reaction (ORR) in proton exchange membrane fuels cells. While a single phase Pd–Co–Au ...

The present paper demonstrates the increased photostability of isotretinoin when loaded in microemulsion. The photodegradation of isotretinoin, in methanol and microemulsion formulation was studied under direct sun light. The photodegradation process was monitored by UV spectrophotometry. In methanol solution, isotretinoin undergoes complete photodegradation just within a few minutes of light e...

he photon correlation spectroscopy and small-angle X-ray scattering is used for study the mixture of C12E5 microemulsion with PEG in order to determine structure and dynamic of the system. Photon correlation spectroscopy experiment showed an exponential relaxation for pure C12E5 microemulsion that come from Brownian motion of oil nano-droplets in water. The shape of the relaxation changed with ...

Microemulsion science has provided a wide range of possibilities in materials fabrication. Here, we describe a novel approach to the synthesis of SrTiO3 nanoparticles of different shapes from a microemulsion. We show that the microemulsion structure plays a critical role in the shape of the nanoparticles, with diffusion-limited growth when normal or reverse micelles are present to nanocuboids w...

BACKGROUND The aim of this study was to develop new systems for transdermal delivery of paeonol, in particular microemulsion gel and cubic gel formulations. METHODS Various microemulsion vehicles were prepared using isopropyl myristate as an oil phase, polyoxyethylated castor oil (Cremophor(®) EL) as a surfactant, and polyethylene glycol 400 as a cosurfactant. In the optimum microemulsion gel...
