This means that the oil or water droplets will not coalesce. On their own, hydrophobic surfactants cannot stabilize an emulsion. Although they are attracted to oil, and an oil-in-water emulsion forms, the emulsion will not stay stable for long and will eventually coalesce. [10]
Emulsified fuels are a type of emulsion that combines water with a combustible liquid, such as oil or fuel. An emulsion is a specialized form of dispersion that contains both a continuous phase and a dispersed phase. The most commonly utilized emulsified fuel is a water-in-diesel emulsion (also known as hydrodiesel). [1]
Second, they can form a water-in-oil emulsion, in which water is the dispersed phase and oil is the continuous phase. Multiple emulsions are also possible, including a "water-in-oil-in-water" emulsion and an "oil-in-water-in-oil" emulsion. [1] Emulsions, being liquids, do not exhibit a static internal structure.
A lower water content makes the concrete stronger and more impervious to water penetration. [2] Similarly, dispersants are used as plasticizers in the gypsum slurry during wallboard manufacture, to reduce the amount of water used. The lower water usage allows lower energy use to dry the wallboard. [3]
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.

Demulsifiers, or emulsion breakers, are a class of specialty chemicals used to separate emulsions, for example, water in oil. They are commonly used in the processing of crude oil, which is typically produced along with significant quantities of saline water. This water (and salt) must be removed from the crude oil prior to refining.
Fill the pan with warm water and mild dish soap, allowing it to sit for 15-20 minutes. This allows time for the stuck pieces to absorb the water, soften, and become easier to loosen. Then begin ...
