Microemulsions have received great attention for applications in transdermal drug delivery. The use of curcumin for treating various skin diseases like scleroderma, psoriasis, and skin cancer was extensively reported. The solubility of curcumin in various oils, surfactants, and cosurfactants was studied herein in order to find the optimal components for a transdermal delivery vehicle. Microemul...

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...

Low-Tension-Foam (LTF) flooding is an emerging enhanced oil recovery technique for low-permeability carbonate reservoirs. Foam capacity closely related to the salinity environment (or, equivalently, phase behavior of oil/water/surfactant system). Therefore, interactions between microemulsion and foam components are primary importance in LTF process. In this study, system under equilibrium analy...

Topical microemulsion of capsaicin without surfactant was developed in this study. In these systems, the oil phase was benzyl alcohol, and the cosurfactant was propylene glycol and ethanol. The drop-size of the systems was measured by dynamic light scattering method in order to distinguish true solution from microemulsion. The transdermal performance of the microemulsions was evaluated in vitro...

We present an innovative methodology for the sustained delivery of hydrophobic drugs using composite hydrogels, prepared by embedding oil-in-water microemulsions in hydrophilic hydrogels. The hydrophobic nature of the microemulsion core enhances the solubilization of hydrophobic drugs, while the crosslinked matrix could be readily used as a solid controlled delivery vehicle. A microemulsion was...

The objective of this study was to select appropriate surfactants or blends of surfactants and oil to study the ternary phase diagram behavior and identify various phases obtained from the oil and surfactant/surfactant mixture combinations of different HLB. The phases include conventional emulsion, gel/viscous and transparent/translucent microemulsion. Pseudoternary phase diagrams of water, oil...

Thin-layer chromatography of nineteen amines has been performed on silica gel layers with a water-in-oil microemulsion (sodium dodecyl sulphate + water + heptane + n-pentanol, 8.0 g + 8.0 mL + 160.0 mL + 25.0 mL) as mobile phase. The effect of the basicity of the amines on their RF values was examined. The proposed thin layer chromatographic method was used to separate isomers of nitroaniline f...

We demonstrate a sol-gel approach, using a water-in-oil microemulsion as the template, for the synthesis of hollow and yolk/shell silica nanospheres, which can encapsulate pre-formed hydrophobic nanoparticles, and we then explore these multifunctional hollow nanospheres in cell-labeling applications.
