The most stable emulsions are formed when the aqueous phase contains no salt and the least stable emulsions are formed at NaCl 1000 mM above this concentration the emulsion stability increases. Pickering emulsion biomaterials drug delivery microspheres nanoparticles. Oil-in-water Pickering emulsions stabilised by fluorescent Stöber silica have been produced. In this article, we give an overview of Pickering emulsions, focusing on some kinds of solid particles commonly serving as emulsifiers, three main types of products from Pickering emulsions, morphology of solid particles and as-prepared materials, as well as applications in different fields. Clegg a Here we study emulsification in a model experimental system comprised of water, an oil and colloidal particles. French,a Je Fowler,b Phil Taylorc and Paul S. Via the so-called Pickering mechanism, these colloidal particles can adsorb irreversibly at the oil-water interface, to sterically (i.e. Pickering emulsions can be applied in a wide range of fields, such as biomedicine, food, fine chemical synthesis, cosmetics, and so on, by properly tuning types and properties of solid emulsifiers. Influence of salt concentration on the formation of Pickering emulsions David J. In conventional emulsions, due to their amphipathic properties, stability and emulsification depend on the arrangement of surfactants at the oilwater interface. Oil-Water-Ratio (OWR), pH of water and brine phase salt concentration were. Besides, they are more biocompatible when solid particles employed are relatively safe in vivo. Pickering emulsions have recently entered the oil and gas sector (Amanullah. Substituting solid particles for traditional surfactants, Pickering emulsions are more stable against coalescence and can obtain many useful properties. Substituting solid particles for traditional surfactants, Pickering emulsions are more stable against coalescence and can obtain many useful properties. Pickering emulsion, a kind of emulsion stabilized only by solid particles locating at oilwater interface, has been discovered a century ago, while being extensively studied in recent decades. This observation challenges current wisdom that so-called Pickering emulsions are at most metastable and points to a new class of mesoscopic equilibrium structures. Pickering emulsion, a kind of emulsion stabilized only by solid particles locating at oil-water interface, has been discovered a century ago, while being extensively studied in recent decades. Once the emulsion has formed, salt has an influence on the final position of trapped particles as described by, w, the three-phase contact angle. We show that under appropriate conditions, mixtures of oil, water, and nanoparticles form thermodynamically stable oil-in-water emulsions with monodisperse droplet diameters in the range of 30-150 nm.
