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.
Submicron emulsions are beneficial for products across numerous industries, including food & beverage, consumer beauty, personal care & cosmetics, and pharmaceuticals. Using a homogenizer for emulsion to produce these types of goods — which might include sauces, seasonings, cosmetic creams, pharmaceutical suspensions, and more — is often the most effective way to create the smaller droplet sizes and higher molecular density that these commodities require. The emulsion process provides numerous advantages, such as:
High-pressure homogenization as a process for emulsion formation is sometimes viewed as cost or energy prohibitive. However, in addition to the above benefits — which cannot be achieved through other methods with the same level of quality and consistency — emulsification technology is continually evolving to offer improved productivity and more favorable resource usage and cost.
Each emulsion product and application will have different ideal droplet sizes. In most cases, sizes between two and five microns will be suitable, though there are many instances where much smaller droplets are required in order to achieve the necessary material properties and quality levels. When considering a homogenizer, remember that:
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.
