Dow Solutions That Allow Highly Stable Emulsions And Microemulsions Dow offers a broad portfolio of solutions that, when combined, provide highly stable emulsions and microemulsions. The ability to not only control but also maintain the well defined size of nanoclusters is key to a scientific understanding as well as their practical application. here, we report a synthetic protocol to prepare and stabilize nanoclusters of different metals and even metal salts. the approach builds on a pickering stabilization effect inside a microemulsion system. we prove that the emulsion.
Highly Stable Oil In Water Emulsions With A Gemini Amphiphilic Microemulsions exhibit high stability against droplet aggregation and gravitational separation, which may improve the bioavailability of highly lipophilic phenolic compounds. in addition, the preparation conditions of microemulsion are simpler than those of nanoemulsion, and the active ingredients can be better encapsulated in the interior. Although being isotropic dispersions of two nonmiscible liquids (oil and water), significant differences are encountered between microemulsions and nanoemulsions. microemulsions are thermodynamically stable o w emulsions of mean droplet size approximately 100–400 nm, whereas nanoemulsions are thermodynamically unstable o w emulsions of mean. An emulsion is defined as a two phase system of two or more immiscible liquids that are thermodynamically and or mechanically stabilized by an emulsifier. nanoemulsions could be used for delivery of both hydrophobic and hydrophilic drugs , and the internal droplet size range is limited to 20–200 nm (solans and solé 2012). Here, we report a synthetic protocol to prepare and stabilize nanoclusters of different metals and even metal salts. the approach builds on a pickering stabilization effect inside a microemulsion system. we prove that the emulsion interface plays a critical role in the formation of nanoclusters, which are encapsulated in situ into a silica.
