“…However, surfactants have limited surface effects when the bubble's lifetime is too short. [45] While a direct link between these concepts has not yet been firmly established in the literature, it is suggested that chemical powders, and gases play a role in influencing the instability and efficiency of the bubble structures in sonochemistry, possibly through changes in the chemical and/or physical environment.…”

Sonochemistry is the use of ultrasonic waves in an aqueous medium, producing acoustic cavitation. In this context, sonochemistry emerged as a focal point over the past few decades, starting as a manageable process such as radar or cleaning technique; now, it is finding wide‐ranging applications across various chemical, physical, and biological processes, creating an opportunity area of analysis between these areas. Sonochemistry is a powerful and eco‐friendly technique often called “green chemistry” for less energy use, toxic reagents, and residues generation, among others. It is increasing the number of applications achieved through the ultrasonic irradiation (USI) method. Sonochemistry has been established as a sustainable and cost‐effective alternative in comparison with the traditional industrial methods, promoting scientific and social well‐being, offering no‐destructive advantages, including rapid processes, improved process efficiency, enhanced product quality, and, in some cases, the retention of key quality characteristics of the products. This versatile technology has significantly contributed to the food industry, materials technology, environmental remediation, and biological research. This review is created with enthusiasm and focus on shedding light on the manifold applications of sonochemistry. It delves into this technique's evolution and current applications in cleaning, environmental remediation, microfluidic, biological, and medical fields.

“…Once the droplet begins to slide, the advancing angle is the maximum stable contact angle and the receding angle is the minimum angle [23]. The critical sliding angle can be predicted by simulating droplet deformation and equilibrium under gravity forces that depend on the surface tension at each interface, the density and the volume of the droplet [24]. A perfect non-return mechanism is one in which the receding angle is 0 and the advancing angle is the same as the static contact angle.…”

“…At this point, the idea of combining high-frequency sound (ultrasound) with eco-detergents emerges as a potential solution. It must be taken into account that depending on the frequency and amplitude of vibration, ultrasonic cavitation can degrade the surfactant [24] in a process called sonolysis. However, rather than being a drawback, this could actually accelerate biodegradation after cleaning.…”

Green chemistry faces a major challenge imposed by the Sustainable Development Goals (6, 14 and 15) defined in the 2030 Agenda. In the case of cleaning products (detergents), the challenges often become a paradox: even if it is biodegradable, no surfactant is harmless to aquatic life. Compared to other studies in the field, this paper covers ultrasound–detergent interactions beyond the cavitation removal process. It also considers synergistic effects with regard to the initial wetting phase and final rinsing. It concludes that the best detergent–ultrasound combination is that which minimises receding and critical sliding angles. At the same time, detergent concentration should be reduced so as to just to capture grease in micelles and avoid reattachment during rinsing. In combination with ultrasound, the concentration of eco-detergents can thus be reduced by up to 10% of their nominal value while attaining the same results.
