Nanoemulsions provide advantages for extract oil and active ingredients with low bioavailability by:
   ① Increasing bioavailability and reducing response time, dose and adverse effects
   ② Masking the taste of the extract oil
   ③ Producing translucent droplet sizes of less than 100nm
An emulsion is a biphasic system in which one phase is dispersed in the other phase in the form of minute droplets with diameter up to 100μm. A nanoemulsion is a colloidal dispersion form including oil and surfactant that can potentially improve the bioavailability of active agents. In additon to the main excipients, nanoemulsions can also include membrane stabilizers, co-emulsifiers, taste-blockers, pH modifiers, osmotic adjusters and anti-oxidants. The droplet size of nanoemulsions typically falls in the range of 20-200 nm. Due to their small size, nanoemulsions are transparent. 
A structure of Nanoemulsion
The four steps of nanoemulsion preparation are:
        ① mixing emulsifier and oil with a stirrer;      ② homogenizing to nanoemulsions;
        ③ sterilization by filtration at 0.22μm;           ④ quality analysis by a particle sizer.  
Genizer provides solutions for nanoemulsions, suitable for batch preparation from 25mL to 10L, or continuous manufacturing from 10mL/min to 20L/hour.

While sonication is effective for small batch nanoemulsions, it is not especially suitable for processing large quantities of certain types of tissues.
The NanoGenizer, a high-pressure homogenizer, is able to produce nanoemulsions with the combined forces of microfluidization and shear. NanoGenizer maximizes particle reduction, speeds up processing and lowers the time and overall cost of production.
Not only can high-pressure homogenizers be used for large batches production of nanoemulsions, they can be set up as part of an inline process, allowing mixing, homogenization, sterilization of large volumes of nanoemulsions without interruption.
Genizer offers the NanoGenizer high-pressure homogenizer for preparation and online sterile filtering for sterilization of nanoemulsions without interruption.  In addition, Genizer also provides the light scattering particle sizer for measuring the size of nanoemulsions.
