Ionic surfactants tend to accumulate in the interfacial region of ultrasonic cavitation bubbles (cavities) because of their surface active properties and because they are difficult to evaporate in cavitation bubbles owing to their extremely low volatilities. Hence. sonolysis of ionic surfactants is expected to occur in the interfacial region of the cavity. In this study. https://herbsdailyes.shop/product-category/glandulars/
