Development of Surfactant-Free Cosmetic Ingredients Using Focused
Ultrasound Technology
A cylindrical ultrasonic generator focuses ultrasonic energy toward the center,
creating a powerful energy concentration at the focal point. As the sample flows through the focused
zone, it is exposed to ultrasonic energy at a set flow rate, enabling uniform emulsification and
dispersion. The sample tube is surrounded by a cooling system, ensuring temperature control and
preventing thermal damage to the sample caused by ultrasonic heating.
