Quadro® equipment successfully overcomes the problems inherent in submicron homogenizing by maximizing productivity while cutting production costs during the emulsification and homogenization process.


The preparation of a nano-scale or submicron homogeneous emulsion involves the homogenization of oil-in-water liquid phases with a mean droplet size ranging from 50nm to less than 1000nm. The stability of a submicron emulsion, achieved through submicron homogenizing, depends on droplet size and the surfactant chemical system (and its concentration) used in the formulation.

Benefits of submicron emulsion:

  • Reduced droplet sizes have desirable effects, including:
    • Stability is improved while reducing the need for thickening agents
    • Submicron droplets in creams or lotions enhance the penetration of active ingredients and improve the protection characteristics of sunscreens
  • Multiple emulsions can be used for sustained release of additive ingredients over time


Several processing methods are used to produce submicron emulsions, but they all suffer from the same limitations: restricted capacity, high energy consumption and frequent maintenance requirements, all of which add to the cost of processing. 


The Quadro® HV-Emulsifier provides more process shear energy than a conventional rotor-stator mill, so submicron droplet size is easily achieved without the subsequent processing of a high-pressure homogenizer. Unlike colloid mills or valve homogenizers, the HV technology effectively creates a submicron emulsion from two separate liquid phases — for example, the homogenization of oil in water — in a single step. This means that the traditional setup of a rotor-stator mixer feeding a valve homogenizer can now be replaced with one machine — the Quadro® HV-Emulsifier — while increasing productivity and reducing cost.

Choose the Quadro® HV-Emulsifier for your submicron homogenizing and experience the benefits of higher capacity, lower energy usage and reduced maintenance.
