Oil in water emulsions are currently used as safe solvents for vaccines. [23] It is important that these emulsion are stable and remain so for long periods of time. Polyelectrolyte stabilized emulsions could be used to increase the shelf life of vaccines. Researchers have been able to develop polyelectrolyte emulsions with more than six month ...
It is commonly used as a viscosity modifier or thickener and to stabilize emulsions in both food and non-food products. It is used primarily because it has high viscosity , is nontoxic, and is generally considered to be hypoallergenic , as the major source fiber is either softwood pulp or cotton linter .
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]
Emulsions contain both a dispersed and a continuous phase, with the boundary between the phases called the "interface". [5] Emulsions tend to have a cloudy appearance because the many phase interfaces scatter light as it passes through the emulsion. Emulsions appear white when all light is scattered equally.
A Ramsden emulsion, sometimes named Pickering emulsion, is an emulsion that is stabilized by solid particles (for example colloidal silica) which adsorb onto the interface between the water and oil phases. Typically, the emulsions are either water-in-oil or oil-in-water emulsions, but other more complex systems such as water-in-water, oil-in ...

A dispersant or a dispersing agent is a substance, typically a surfactant, that is added to a suspension of solid or liquid particles in a liquid (such as a colloid or emulsion) to improve the separation of the particles and to prevent their settling or clumping. [1]
The woman managed to free herself and called the police. She was unharmed but told officers Godoy’s comments had made her fear for her life. “Obviously she was terrified,” Alexander said ...
