The basic principle of emulsion production is the increase of the specific interface, i.e. the phase correlated with volume. A result that is achieved by applying mechanical and thermal energy; the energy required to disperse the liquid into individual beads is described by the formula K=σ. Or, where σ is the interfacial tension and the new interfacial tension.

By using a suitable emulsifier system, the energy required by the process can be drastically reduced.

Emulsions are produced according to the following steps:
• Division of substances in two phases.
• Heating and mixing of the two phases.
• Creation of a vacuum.
• Introduction of one phase into the other while stirring.
• Emulsification and homogenization.
• Cooling.

The diagram on the following page describes the stages of a conventional Emulsification process.
