An emulsion is a two-phase system of two immiscible liquids, where one phase, the so-called internal or dispersed phase, is distributed as small droplets into the other, so-called external or continuous, phase. To prepare an emulsion, generally energy input into the two-phase system is required. Ultrasonic shear forces are well proven to be highly efficient to produce long-term stable emulsions with nano-sized droplets and of superior quality.
Oil-in-water (O/W) emulsions are widely used in many consumer products such as food, beverages, cosmetics, pharmaceuticals etc. as well as in industry (e.g. material science, polymers, paints, coatings, fine chemistry etc.).
An oil-in-water emulsion is a mixture in which an oily phase is dispersed in water or another aqueous liquid. Small droplets of oil are finely dispersed in the water phase (continuous phase) to create this oil-in-water emulsion. If oil (dispersed phase) is dispersed in water (continuous phase), it is an oil-in-water emulsion; if water droplets are added into an oily continuous phase, it is called a water-in-oil emulsion.
Ultrasonically Improved Emulsion Stability
The physical effects of ultrasound induced by acoustic cavitation results in the disruption of oil and water droplets and facilitates thereby the formation of stable O/W and W/O emulsions with very small droplets size in the micron- and nano-size. Due to very small droplet size and its high surface area, nanoemulsions offer extraordinarily high bioactive properties, which is important for foods and supplements, pharmaceuticals and cosmetic production. Due to the minute droplet size, the bioactive compound can penetrate cells rapidly. Also in material science and industry, nano-emulsions are important for the manufacturing of high-performance coatings, paints, polymers and other composites. Ultrasonically prepared nanoemulsions are usually significantly more stable than macroemulsions and do not show sedimentation, coalescence or flocculation.
