ferulic acid lecithin-based nano-emulsions prepared by using spontaneous emulsification process

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 <...

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

Formation and stability of Vitamin E nano-emulsion based delivery systems by spontaneous emulsification method: Glycerol as a co-solvent

There is considerable interest in using nano-emulsions (NEs) as delivery systems for lipophilicbioactive ingredients. In this study, the influence of G on the properties of vitamin E (VE) enriched NEsprepared using spontaneous emulsification (SE) method, were investigated. The particle size and optical clarityof the NEs depended strongly on the co-solvent presence, absence, an...

Dispersion of oil into water using lecithin-Tween 80 blends: The role of spontaneous emulsification.

Lecithin-rich mixtures of the nontoxic surfactants lecithin and Tween 80 are effective marine oil spill dispersants, but produce much higher oil-water interfacial tension than other, comparably effective dispersants. This suggests interfacial phenomena other than interfacial tension influence lecithin-Tween 80 dispersants' effectiveness. The interface between seawater and dispersant-crude oil m...

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 ...

Studies on the formation of O/W nano-emulsions, by low-energy emulsification method, suitable for cosmeceutical applications.

The formation of oil/water (O/W) nano-emulsions suitable for cosmeceutical application was studied. Nano-emulsions were prepared by using phase inversion composition (PIC) method, one of the low-energy emulsification methods. The process consist of stepwise water addition to oil/surfactant mixture, at T = 25°C. Caprylic/capric triglycerides (GTCC), propylene glycol dicaprylate/dicaprate (PC) an...
