Advanced Nanoemulsions

Abstract

Recent advances in the growing field of nanoemulsions are opening up new applications in many areas such as pharmaceuticals, foods, and cosmetics. Moreover, highly controlled nanoemulsions can also serve as excellent model systems for investigating basic scientific questions about soft matter. Here, we highlight some of the most recent developments in nanoemulsions, focusing on methods of formation, surface modification, material properties, and characterization. These developments provide insight into the substantial advantages that nanoemulsions can offer over their microscale emulsion counterparts.

Microemulsion of Brazil nut oil as a natural product to improve superoxide release in human phagocytes

“…[1][2][3][4][5] Microemulsions have also been identified as potential delivery systems for bioactives in foods, pharmaceutical and cosmetic formulations. 6 There are several types of nanostructures, and microemulsions (MEs) are one of them, that can be used as carriers for lipophilic bioactive compounds, drugs or nutrients. [7][8][9][10] MEs are thermodynamically stabilized oil-water dispersions (100 nm droplets) that are macroscopically homogeneous, translucent and stabilized by a surfactant and cosurfactant interfacial film.…”

Production of Tocols Nanoemulsion by Ultrasonication

“…Brij 35 has smaller molecular weight compared to Tween 80 or Tween 20 thus can be quickly adsorbed onto the newly formed oil-water interface during homogenisation to prevent coalescence of droplets. As the droplet size in the emulsion system decreases to less than 100 nm in diameter, it appears visibly from white to transparent or translucent due to the light being weakly scattered by these fine oil droplets (Fryd and Mason, 2012). As shown in Figure 5, the Particle size and size distribution of these droplets are critical criteria that affect the stability of emulsion.…”

A comparative study of efficiency of different ivermectin medicinal forms for treating helmintosis in live-stock animals

“…Nanoemulsions are also known as miniemulsions, ultradisperse emulsions and submicronic emulsions. Nanoemulsions are emulsions with an average particle diameter from 10 to 1000 nm [6]. The particle size depends on the quantitative composition of the emulsion and the ratio of active and auxiliary components [8].…”
