	Reference.com/Encyclopedia/Emulsion
		Emulsions tend to have a cloudy appearance, because the many phase interfaces (the boundary between the phases is called the interface) scatter light that passes through the emulsion.
		Although the terms colloid and emulsion are sometimes used interchangeably, emulsion tends to imply that both the dispersed and the continuous phase are liquid.
		There are three types of emulsion instability: flocculation, where the particles form clumps; creaming, where the particles concentrate towards the surface (or bottom, depending on the relative density of the two phases) of the mixture while staying separated; and breaking and coalescence where the particles coalesce and form a layer of liquid.

		Place the emulsion in a square of cheesecloth and fold the cloth over it.
		Hold the emulsion in a pan of cold water and twist the cloth so it is squeezed through the pores in the cheesecloth, making a kind of gelatin spaghetti.
		The use of distilled water is recommended, to reduce the possibility of unknown contaminants in the emulsion.

	Wikinfo \| Emulsion (Site not responding. Last check: )
		An emulsion is a stable and homogenous mixture of two liquids which do not normally mix (they are immiscible between themselves), such as Vegetable oil and water.
		Emulsions can be true colloids or less stable mixtures, such as salad dressing (a mixture of balsamic vinegar and olive oil), which tend to separate in a short time.
		An emulsion paint (often abbreviated to emulsion) is a water-based paint commonly used for painting indoor surfaces.

	Emulsion Summary
		Emulsions tend to have a cloudy appearance, because the many phase interfaces (the boundary between the phases is called the interface) scatter light that passes through the emulsion.
		Fluid emulsions can also suffer from creaming, the migration of one of the substances to the top of the emulsion under the influence of buoyancy or centripetal force when a centrifuge is used.
		Although the terms colloid and emulsion are sometimes used interchangeably, emulsion tends to imply that both the dispersed and the continuous phase are liquid.

	Oilfield Glossary: Term 'emulsion'
		Two emulsion types are used as muds: (1) oil-in-water (or direct) emulsion, known as an "emulsion mud" and (2) water-in-oil (or invert) emulsion, known as an "invert emulsion mud." The former is classified as a water-base mud and the latter as an oil-base mud.
		Emulsions can form when fluid filtrates or injected fluids and reservoir fluids (for example oil or brine) mix, or when the pH of the producing fluid changes, such as after an acidizing treatment.
		Emulsions are normally found in gravel packs and perforations, or inside the formation.

	Emulsion - Pharmpedia
		Emulsions are biphasic systems consisting of two immiscible liquids, one of which (the dispersed phase) is finely subdivided and uniformly dispersed as droplets throughout the other phase (the dispersion medium).
		An emulsion is said to cream when the oil or fat rises to the surface, but remains in the form of globules, which may be redistributed throughout the dispersion medium by shaking.
		W/o emulsions are oily and greasy in nature, not easily removable from the surface of the skin whereas o/w emulsions are non greasy and easily removable from the skin surface.

	Oil Analysis and Lubrication Dictionary
		a separator that divides a mixture or emulsion of two immiscible liquids using the interfacial tension between the two liquids and the difference in wetting of the two liquids on a particular porous medium.
		Emulsions may be of two types: oil-in water (where water is the continuous phase) and water-in-oil (where water is the discontinuous phase).
		Three common types of fire-resistant fluids are: (1) water-petroleum oil emulsions, in which the water prevents burning of the petroleum constituent; (2) water-glycol fluids; and (3) non-aqueous fluids of low volatility, such as phosphate esters, silicones, and halogenated hydrocarbon-type fluids.

	U.S. Screen Print and Inkjet Technology - Choosing The Best Emulsion
		Emulsion is a light-sensitive liquid that is coated onto a screen or film that is adhered with the use of water.
		The newest of the three, diazo-photopolymer emulsion (also called "dual-cure emulsion") Although it must be mixed like diazo, because it also is sensitized with diazo, dual-cure arrives from the manufacturer with some light sensitivity because the base has a photoreactive resin, Dennings says.
		Apply emulsion from the substrate side of the screen and coat as many times as it takes for the emulsion to surface on the squeegee side, Dennings says.

	Emulsions
		The process is done under water where the emulsion is removed, then arranged onto a variety of mediums while wet, often with intentional wrinkles and strategic tears that create a dynamic and almost dimensional version of the original image.
		The emulsion was placed on paper with a special silver-painted finish, which gives the original a beautiful shiny glow throughout the image.
		Emulsions can also be layered or overlapped on paper or glass, or on multiple sheets of paper or glass.

	Etherington & Roberts. Dictionary--emulsion (Site not responding. Last check: )
		The droplets of the dispersed liquid are known as the inner phase of the emulsion because it appears to be inside the liquid medium.
		To form a stable emulsion, a third ingredient must be present; it is called an emulsifier, or emulsifying agent, and forms absorbed films around the tiny globules of the dispersed fluid to prevent them from coalescing.
		Emulsions are generally opaque or milky because of the refraction and dispersion of light by the minute droplets, but when dry they become transparent, or nearly so.

	Emulsion System (Site not responding. Last check: )
		These two requirements mean that we need an emulsion for which the dispersed (oil) phase and the continuous (“water”;) phase are refractive index matched, to remove opacity, and density matched, to eliminate creaming.
		This “frogspawn” image shows an emulsion in which the dispersed phase is a hexane-FC-72 mix, but because the emulsion temperature dropped below the consolute point the oil phase separated, giving a double emulsion comprising droplets of one oil inside droplets of the other.
		The resulting aggregated emulsion system is sufficiently transparent and languid that we are able to extract full 3D images using confocal microscopy.

	Emulsion based explosives \| explosive demolition \| explosive safety
		An emulsion is made up of a mixture of two liquids that do not normally mix with one another, as one liquid is oil-based, and the other liquid is water-based.
		Emulsion explosives are, therefore, prepared in the form of water-in-oil emulsions.
		Since each microcell of the oxidizer is coated with an oily exterior, the emulsion has excellent water resistance and does not rely on a pack-age for their ability to function efficiently in water.

	Emulsion Polymerization
		The reaction proceeds at 50 degrees C for 12 hours until the conversion reaches 72%, then the reaction is terminated by the addition of hydroquinone to minimize crosslinking.
		The molecular weight gain may be higher for emulsion polymerization may be higher than for a similar bulk polymerization.
		Emulsion does not require a vigorous mechanical separation (e.g., stirring) which is necessary for suspension polymerization to keep the monomer bubbles from coming together to form one phase.
