emulsion

 [e-mul´shun]
a mixture of two immiscible liquids, one being dispersed throughout the other in small droplets; a colloid system in which both the dispersed phase and the dispersion medium are liquids. Margarine, cold cream, and various medicated ointments are emulsions. In some emulsions the suspended particles tend to join together and settle out; hence the container must be shaken each time the emulsion is used.
film emulsion a dehydrated gel emulsion of light- or radiation-sensitive silver halide that is applied to a suitable base.

e·mul·sion

(ē-mŭl'shŭn),
A system containing two immiscible liquids in which one is dispersed, in the form of small globules (internal phase), throughout the other (external phase) (for example, oil in water [milk] or water in oil [mayonnaise]).
[Mod. L. fr. e-mulgeo, pp. -mulsus, to milk or drain out]

emulsion

Pharmacology A suspension of droplets of one liquid in another–eg, oil, water. See Emulsifier.

These emulsions showed good stability against ionic strength change, but low pH may affect their stability.
To minimize the negative effect of micelles on the stability of the emulsions and [alpha]-tocopherol therein [19], the minimum emulsifier concentrations (MECs) required to prepare highly stable emulsions with mostly small droplets were determined in our previous study [7].
In order to examine the stability of prepared emulsion, the prepared emulsions were stored in clean air tight vessels and studied as a function of storage time.
The water resistance increases with the increasing emulsion content, however the explosive power per pound will generally decrease as the emulsion content is increased.
Emulsion and gel could be mixed in preparation called emulgel,5 O/W emulsion for lipophilic materials while W/O for hydrophilic materials.6 Emulgels are thixotropic, greaseless, easily spreadable, easily removable, emollient, non-staining, bio-friendly, transparent and cosmetically acceptable.2 They also have good cutaneous penetration7 and long shelf-life.8 This all make emulgels an advantageous topical drug delivery system.
These calculators take into account things like the size of the walls, windows and doors, but not the type of emulsion you're using or the state of the walls themselves.
Although the Sweet Sap has been used successfully in making emulsions, and subsequently paints, the major challenge was to stabilize it by preventing the initiation of fermentation.
BME said the long shelf-life of the emulsions makes them easier to store, allowing mines to reduce supply chain risk where distances and accessibility make transportation difficult; and they do not require dedicated magazine facilities, saving on cost and administration.
Table 2 shows the values of viscosity and dispersion of emulsions prepared using this apparatus.
Western Emulsions is a a supplier of branded and standard asphalt emulsions, and raw asphalt used for pavement preservation, repair and restoration projects.
In addition to the above emulsion, few researches included concepts of introducing three-phase emulsions and comparative studies on the effect of two-phase and three-phase on the diesel engine performance also available.
Several quantities characterize nuclear emulsions as a particle detector.
