This review examined some approved formulations and discussed the advantages of using nanocarriers in cancer therapy. Emulsions are of great importance in the plastics industry ie in polymersparticularly in the detergent and cleaning products, in the production of lubricants, cosmetic compositions, veterinary or pharmaceutical eg ointments and ointments and, particularly in the technology of food products himself.

Since many emulsions comprise at least one hydrophilic liquid and at least one lipophilic liquid, a further distinction micelas lipidicas usually made, depending on the nature of the internal disperse phase, between oil-in-water emulsions and water in oil.

The internal phase or the external phase of the emulsion micelas lipidicas in turn be a disperse system and may, for example, comprise particles of solids dispersed in the respective liquid phase, referring to a system micelas lipidicas this type as multiphase emulsion.

Because the interfacial tension between the droplets of the internal phase and the droplets of the external continuous phase, the emulsions generally are thermodynamically unstable and thus after some time a phase separation which may be caused occurs, for example by sedimentation or coagulation of droplets.

micelas lipidicas When mixed together the at least two components in liquid phase, the initial result is a thick disperse crude emulsion.

By providing mechanical energy, the large drops of the crude emulsion are rolled and fine emulsion was intended forms.

The minimum droplet micelas lipidicas achievable under the last stage of the emulsification process depends not only on the respective input of power in the emulsifying equipment but can also be greatly influenced by the nature and concentration aids emulsification.

For example, to produce ultrafine emulsions, it is essential that the new contact surfaces are mechanically look occupied very rapidly by the emulsifier in order to prevent binding of the droplets.

Emulsions with a viscosity medium to high occurs primarily by rotor-stator micelas lipidicas, such as colloid mills or dispersing machines crown.

It is assumed that the breakage of the drops in this case is mainly attributable to the effect of cavitation.

A specific type of homogenizer is the microfluidizer, which operates at relatively low micelas lipidicas of about bar. However, high pressure homogenizers are not without disadvantages.

Especially when they are emulsifying polymerizable systems or when multiphase are emulsions comprising solid particles are micelas lipidicas, the narrow radial gap of the homogenizing nozzle may be clogged easily.
