Most often this means application to body surfaces such as the skin or mucous membranes to treat ailments via a large range of classes including creams, foams, gels, lotions, and ointments.
Ointment Emulsion Results
Ultrasonic emulsification is to point to in the role of ultrasonic energy, make the two (or more than two) are not solution mixing body form disperse system, one of the liquid is uniformly distributed in another liquid and the processes of forming emulsion. Ultrasonic emulsification and emulsion technology and equipment, such as screw, colloid mill and homogenizer, etc.), compared with high quality of emulsification, emulsifying stability, low product emulsion stability and the required power, etc.
The Effect of Ultrasonic Emulsion Machine
Ultrasonic emulsification equipment use strong ultrasonic effect causes the liquid in the crushed into insoluble solid (or other liquid) particles and mixed with the fluid surrounding the full form of emulsion technology. The physical mechanism of ultrasonic emulsification equipment is thought to be ultrasonic cavitation effect. Ultrasonic cavitation effect refers to the strong under the action of ultrasonic, liquid will produce a lot of bubbles, small bubbles will growth and increased gradually along with ultrasonic vibration, and then suddenly burst and division, division of bubbles and continuous growth and burst. These small bubbles collapse rapidly to produce the high temperature and high pressure in the bubble, and because of air bubbles in the fluid surrounding the high-speed into bubbles near the bubble in a liquid has a strong local shock, also formed the local high temperature and high pressure, result in ultrasonic grinding, ultrasonic emulsification.
