SUBMICRON HOMOGENEOUS EMULSIONS
WHAT IS SUBMICRON HOMOGENIZATION?
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
THE APPLICATION CHALLENGE
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® SOLUTION
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.
