 Emulsion - Wikipedia, the free encyclopedia
An emulsifier (also known as a surfactant or surface active material) is a substance which stabilizes an emulsion.
Examples of food emulsifiers are egg yolk (where the main emulsifying chemical is lecithin), and mustard, where a variety of chemicals in the mucilage surrounding the seed hull; proteins and low-molecular weight emulsifiers are common as well.
Generally, the Bancroft rule applies: emulsifiers and emulsifying particles tend to promote dispersion of the phase in which they do not dissolve very well; for example, proteins tend to form oil-in-water emulsions.

 Oilfield Glossary: Term 'oil-mud emulsifier'
An oil-mud emulsifier lowers the interfacial tension between oil and water, which allows stable emulsions with small drops to be formed.
Emulsifiers can be calcium fatty-acid soaps made from various fatty acids and lime, or derivatives such as amides, amines, amidoamines and imidazolines made by reactions of fatty acids and various ethanolamine compounds.
Emulsifier molecules that cannot fit around drops form clusters (micelles) in the oil phase or adsorb onto solids.

 Shear emulsifiers and emulsion with emulsion stability - Admix Rotostat
The patented mixing head of the emulsifier consists of an internal rotor surrounded by a freely revolving stator.
The rotor of the emulsifier draws the product into the stator of the emulsifier where the high shear action between the high-speed rotor blades and the slowly revolving stator rim subjects the material to very effective milling and grinding action prior to being expelled with high velocity through outlets in the stator rim.
When passing through these outlets, of the emulsifier, particles, agglomerates, solids, etc. are exposed to intense cutting and disintegrating action for a further reduction of particle sizes.

Setser's analysis shows that cakes made with the emulsifier were -- to a crumb -- lower in fat and lower in calories than traditional cakes.
Controlling the proportions of the ingredients, including the pre-formed emulsifier, is what determines a cake's structure, which can be varied from the denseness of pound cake to the airiness of sponge cake.
Setser is hopeful the commercial baking industry will adopt the patented pre-formed emulsifier for new products, and she foresees at least one possible use in frozen bakery goods.

An emulsifier consists of molecules with a hydrophile end, which is polar of ionic or non-ionic nature, and a lipophile end, which is a hydrocarbon chain of a certain length.
An emulsifier which binds with equal strength to both phases is ideal for just that emulsion.
The hydrocarbon chain of the emulsifier must then be quite long in order for it to bind sufficiently strongly to oil phase.

 Oily Waste Control with Alken 860 De-emulsifier, page 1   (Site not responding. Last check: 2007-11-07)
Seawater acts as a natural emulsifier, increasing the viscosity of the oil-water waste which makes it difficult to pump the waste from the barges to shore tanks for processing.
When the flash point of the emulsified oil is high enough that it is unlikely to create a fire hazard, steam heat, in a temperature range of 150° F to 200° F, may be injected to the emulsified oil to increase the speed of the emulsion break-up.
The resulting clarification, or emulsion breaking, is believed to result from the destruction of the emulsifying agents by neutralizing or reversing interfacial film electrical charges, and in turn, by agglomeration of the precipitated floc, and adsorption of the suspended oily matter on the floc surface.

 Tech Notes - New York SCC
When studying the sequence of the emulsifier (system) numbers, it was noticed that these were roughly the same for the low-performing emollient as well as the high-performing emollient, but, more importantly, also for all three efficacies.
This indicates the performance of an emulsifier to be independent of the type of emollient studied (which dictates the type of efficacy) as well as the quality of this emollient in achieving this effect.
When the emulsifier with a medium EEE is used, the average increase when adding 6% glycerin is 11.4% for the low-performing emollient and 10.1% for the high performing emollient.
