[P1.030] Preparation of nano-emulsions using SPG Membrane Emulsification -Application to Vitamin E Encapsulation

Preparation of uniform particle-stabilized emulsions using SPG membrane emulsification.

Various aspects of particle-stabilized emulsions (or so-called Pickering emulsions) have been extensively investigated during the last two decades, but the preparation of uniform Pickering emulsion droplets via a simple and scalable method has been sparingly realized. We report the preparation of uniform Pickering emulsions by Shirasu porous glass (SPG) membrane emulsification. The size of the ...

On the preparation of lecithin-stabilized oil-in-water emulsions by multi-stage premix membrane emulsification

Ferulic Acid Lecithin-Based Nano-Emulsions Prepared by Using Spontaneous Emulsification Process

Ferulic acid (4-hydroxy-3-methoxycinnamic acid), an effective component of medical plant, is a phenolic acid with low toxicity that can be absorbed and easily metabolized in the human body. The solubility of Ferulic Acid (FA) is very low in aqueous solutions which can cause problem in preparation of pharmaceutical products, but it can easily be dissolved in oil/water interface of <...

Water fluxes and encapsulation efficiency in double emulsions: impact of emulsification and osmotic pressure unbalance.

We study the influence of the emulsification process on encapsulation efficiency of drugs in double water-in-oil-in-water emulsions. Two drugs were used, first vitamin B12 which can be considered as a model drug and secondly a suspension of Cydia pomonella Granulovirus (CpGV), a virus used in organic agriculture to protect fruits against the Carpocapse insect. Encapsulation is measured by class...

Optimization and Evaluation of Monodispersed Tetrandrine-Loaded PLA Microspheres Prepared With A SPG Membrane Emulsification Technique

To improve pulmonary drug concentrations and to maximize the effectiveness and minimize the adverse side effects, uniformsized tetrandrine-loaded polylactide (PLA) microspheres with a suitable particle size for pulmonary inhalation were prepared by the Shirasu Porous Glass (SPG) membrane emulsification technique. The main parameters influencing PLA microsphere properties were investigated: tran...
