The aim of the present study was determine optimum processing conditions and nanoemulsion formulation for preparation gingerol shogaol from ginger extract-based subcritical water. For this purpose, nanoemulsions were prepared with rotor-stator homogenizer varied surfactant cosurfactant concentrations (24%, 26% 28% v/v), stirring speed (22,000 rpm, 24,000 rpm). time is adjusted to 30 minutes. de...

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...

Objective: The study aims to develop a Self-nanoemulsifying drug delivery system (SNEDDS) of Quercetin enhance its oral bioavailability.
 Methods: In the present study, was formulated into SNEDDS using various oils, surfactants, and co-surfactants. developed formulations were subjected studies like content analysis, droplet size thermodynamic stability, in vitro release studies.

in this work, we report on the synthesis of superparamagnetic iron oxide nanoparticles at room temperature using microemulsion template phase consisting of cyclohexane, water, ctab as cationic surfactant and butanol as a cosurfactant. surface modification have been carried out by using poly(ethyleneglycol) (peg). the structure,morphology, and magnetic properties of the products were characteriz...

2014 The roughening transition of the interface in a model mixture of amphiphilic diblock copolymers, two immiscible solvents and a monomeric cosurfactant is examined. The equivalence of this model with the solid-on-solid Ising magnet implies the existence of a critical cosurfactant composition XRAB for the transformation of a lamellar microemulsion phase into a bicontinuous disordered structur...

In the present work specific adsorption phenomena of metal ions at the water –oil interface are studied. Bicontinuous microemulsions were chosen as a model system because of their high specific surface between water and oil phases. Mixing an extremely hydrophobic extractant considered here as the co-surfactant with an extremely hydrophilic sugar surfactant we succeed to formulate microemulsion ...
