“…In particular, mixtures of nonionic fast-adsorbing aroma molecules and conventional (ionogenic) micellar-forming surfactants are an interesting model system with significant applied potential. 24,25,47 In the following, we describe the interfacial behavior of SDS−benzyl acetate mixtures under dynamic conditions. Figure 6a shows the surface tension, measured with the MBP method, of SDS and benzyl acetate individual solutions, as well as of their mixtures with a constant fraction of benzyl acetate of 0.5 and 0.25 versus the total molar concentration of surfactants in solution.…”

“…Depending on its composition and targeted application, each multicomponent surfactant system requires a specific choice of measuring methods and adjustment of experimental conditions with regards to the time scale and concentration range. In particular, mixtures of nonionic fast-adsorbing aroma molecules and conventional (ionogenic) micellar-forming surfactants are an interesting model system with significant applied potential. ,, …”

“…However, the use of classical equilibrium methods of colloid chemistry has led to a misapprehension of the effect of aroma molecules on dynamic interfacial processes. It is only recently, that individual interfacial activity − and fast-adsorbing behavior of aroma molecules ,, have been unveiled by measuring dynamic and equilibrium surface tension of individual and of mixed surfactant solutions. These studies indicated the high potential of aroma amphiphilic molecules in dynamic interfacial processes.…”

Multicomponent heterogeneous systems containing volatile amphiphiles are relevant to the fields ranging from drug delivery to atmospheric science. Research presented here discloses the individual interfacial activity and adsorption–evaporation behavior of amphiphilic aroma molecules at the liquid–vapor interface. The surface tension of solutions of nonmicellar volatile surfactants linalool and benzyl acetate, fragrances as such, was compared with that of the conventional surfactant sodium dodecyl sulfate (SDS) under equilibrium as well as under no instantaneous equilibrium, including a fast-adsorbing regime. In open systems, the increase in the surface tension on a time scale of ∼10 min is evaluated using a phenomenological model. The derived characteristic mass transfer constant is shown to be specific to both the desorption mechanism and the chemistry of the volatile amphiphile. Fast-adsorbing behavior disclosed here, as well as the synergetic effect in the mixtures with conventional micellar surfactants, justifies the advantages of volatile amphiphiles as cosurfactants in dynamic interfacial processes. The demonstrated approach to derive specific material parameters of fragrance molecules can be used for an application-targeted selection of volatile cosurfactants, e.g., in emulsification and foaming, inkjet printing, microfluidics, spraying, and coating technologies.

“…Related studies have shown that surface tension and viscosity can significantly affect the collision and agglomeration behavior of droplets [10,11], which can alter the particle size and velocity distribution of droplets in the spray field and consequently affect the atomization effect. Compared to atomization, factors such as pressure, surface tension, and viscosity have a more significant impact on the atomization effect [12,13].…”

To investigate the influence of surface tension and viscosity on the atomization performance of solid cone nozzles and improve their dust reduction efficiency in industrial and mining enterprises, this study employed a self-built PDPA dust-fog coupling experimental system to explore the effects of different surface tension and viscosity solutions on atomization performance from three aspects: axial, radial, and fog field distribution. The experimental results indicate that compared with surface tension, surface tension has a greater influence on droplet size and velocity in the axial direction. In the radial direction, increasing surface tension and reducing viscosity within a certain range can make the droplet size and velocity distribution more uniform. Additionally, surface tension and viscosity significantly affect the fog field distribution. It was found that a decrease in surface tension can result in a closer proximity of the droplet velocity and size expansion area to the nozzle, while an increase in viscosity can lead to a more prolonged stable area. Furthermore, optimizing the surface tension and viscosity can significantly enhance the efficacy of dust reduction for respirable dust. Consequently, the application of the aforementioned atomization principles to regulate the fog field characteristics of solid cone nozzles can effectively mitigate dust in the production process and augment the dust reduction rate of industrial and mining enterprises.
