Whether in the Chemical, Pharmaceutical, Cosmetics or Food Industry, the costs for raw materials is permanently increasing all over the world and in all fields.
Manufacturing companies search for new processes and new possibilities to remain competitive and distinguish themselves from their competitors. Occasionally, they are successful by, for example, substituting expensive raw materials with cheaper ones.
Another possibility for savings is to reduce the raw materials consumed in production but, if quality is to be maintained, it is often necessary for processing steps to be modified or improved.
A large variety of products, such as lacquer and paint, glue and binders, baby food and beverages, detergents and shampoos, as well as drugs and creams are being produced based on a number of dispersions. A prevalent type of dispersion is the suspension, consisting of heterogeneous liquids with finely dispersed particles in it. The two components do not dissolve or combine chemically and will eventually sediment if left unattended.
