Dispersion creates a heterogeneous mixture from at least two substances that hardly dissolve in each other or combine chemically. One substance, the dispersed phase, is distributed as finely as possible in another, the dispersion medium or continuous phase.<\/p>

What happens during dispersion<\/h2>

At the interface between two phases, interfacial tension arises. It strives for the smallest possible interface and thus prevents a dispersed system<\/a>. Dispersing enlarges the interfaces of the individual phases and so creates a balance. It is therefore an intense, sudden reduction in size of liquid droplets and solid particles. Emulsifiers and stabilisers then make the product stable for a long time.<\/p>

Emulsions and suspensions<\/h2>

In industry, dispersing is mostly used to produce emulsions or suspensions. Both have a liquid continuous phase.<\/p>

<\/i>

Emulsion<\/h3>

The dispersed phase is also liquid, for example oil in water. More on our emulsification<\/a> page.<\/p><\/div>

Suspension<\/h3>

Here, solid particles spread in a liquid. More on our suspension<\/a> page.<\/p><\/div><\/div>

What matters in dispersion<\/h2>

Dispersing should be simple and efficient without compromising the quality of the end product. After all, nobody wants to buy a cream that separates into its phases after a while.<\/p>
