Pharmaceutical ointments<\/a> are single-phase, semi-solid and spreadable preparations with incorporated active ingredients<\/a>. The active ingredients are added according to a fixed recipe and dissolved, dispersed<\/a> or suspended in the base.<\/p>

Types of bases at a glance<\/h2>
<\/i>

Hydrophobic<\/h3>

They are very greasy, water-repellent and cannot be washed off with water. Only very small amounts of water are worked in by mechanical dispersion<\/a>.<\/p><\/div>

<\/i>

Hydrophilic<\/h3>

Their bases can be mixed with water. Although they are fat-like, they are not greasy. They are glossy, easy to spread and can be washed off with water.<\/p><\/div>

<\/i>

Water-absorbing<\/h3>

They absorb larger quantities of water when an emulsion is formed.<\/p><\/div><\/div>

An emulsion<\/a> is a finely distributed, stable mixture of two liquids that do not normally mix. One phase is distributed in the other in the form of fine droplets \u2013 either as a water-in-oil (W\/O) or an oil-in-water (O\/W) emulsion.<\/p>

Homogenising mixers for ointment production<\/h2>

Homogenising mixers are particularly well suited to the production of pharmaceutical ointments. Modern machines can:<\/p>
