Emulsions are used to manufacture polymer dispersions – polymer production in an emulsion 'phase' has a number of process advantages, including prevention of coagulation of product. Products produced by such polymerisations may be used as the emulsions – products including primary components for glues and paints.
In polymer chemistry, emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomers, and surfactants.The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.
Photographic emulsion is a light-sensitive colloid used in film-based photography. Most commonly, in silver-gelatin photography , it consists of silver halide crystals dispersed in gelatin . The emulsion is usually coated onto a substrate of glass , films (of cellulose nitrate , cellulose acetate or polyester ), paper, or fabric.
In some old processes, the film emulsion was hardened during the process, typically before the bleach. Such a hardening bath often used aldehydes, such as formaldehyde and glutaraldehyde. In modern processing, these hardening steps are unnecessary because the film emulsion is sufficiently hardened to withstand the processing chemicals.
The most commonly utilized emulsified fuel is a water-in-diesel emulsion (also known as hydrodiesel). [1] In these emulsions, the two phases are immiscible liquids—water and oil. Emulsified fuels can be categorized as either microemulsions or conventional emulsions (sometimes called macroemulsions to distinguish them from microemulsions).
Alternative names for these systems are often used, such as transparent emulsion, swollen micelle, micellar solution, and solubilized oil. More confusingly still, the term microemulsion can refer to the single isotropic phase that is a mixture of oil, water and surfactant, or to one that is in equilibrium with coexisting predominantly oil and ...
This type of emulsion is thermodynamically unstable, but can be stabilized for a period of time with applications of kinetic energy. [1] Surfactants (as the main emulsifiers) are used to reduce the interfacial tension between the two phases, and induce macroemulsion stability for a useful amount of time. Emulsions can be stabilized otherwise ...
Lipid emulsion or fat emulsion refers to an emulsion of fat for human intravenous use, to administer nutrients to critically-ill patients that cannot consume food. It is often referred to by the brand name of the most commonly used version, Intralipid , which is an emulsion containing soybean oil , egg phospholipids and glycerin , and is ...
