“…As the cavitational events occurring during the process of ultrasonication increase with time of sonication and power of ultrasound, collision of these events near the surface of the droplets will direct the droplets to break further into small droplets. Increase in the emulsifier concentration decreases the chances of coalescence and/or aggregation as the emulsifier load which is the excess surface concentration of the emulsifier at saturation at the interfacial region decides the extent of coalescence of the droplets [17]. If the concentration of the emulsifier is less than the emulsifier load, then droplet coalescence will occur and it also depends on the volume fraction of the oil.…”

“…Usually, homogenizers or ultrasonicators are used to impart external forces that help in formulation of NE [9] . Main factors that influence the size of NE include energy intensity and duration, the surfactant type and concentration, and the physicochemical properties of the oil and water phases [8,10] .…”

The present study was carried out to fabricate the food grade vitamin E acetate nanoemulsion (NE) using edible mustard oil and to evaluate its improved bioactivities. A food-grade vitamin E acetate nanoemulsion was fabricated using the edible mustard oil and surfactant tween-80 and flocculation was not observed for 15 days. The nanoemulsion was characterized for droplet morphology and size distribution using atomic force microscope and zetasizer respectively. We observe a stable nanoemulsion of spherical morphology and a size distribution of 86.45 ± 3.61 nm. Further, the HPLC method was used to determine the vitamin E acetate concentration and encapsulation efficiency for the stable nanoemulsion. These nanoemulsions showed improved bioactivity -antioxidant and antimicrobial activity and could be potentially used to increase the shelf life of fruit juice.

“…During one of the low pressure cycles, cavitation results in formation of bubbles. These bubbles contract and expand until implosion, creating disturbance in the local flow field which ultimately breaks the droplet [20][21][22] ( Fig. 1(b)).…”

Controlling and predicting droplet size of nanoemulsions: scaling relations with experimental validation

et al. 2016

a Nanoemulsions possess powerful nano-scale properties that make them attractive for diverse applications such as drug delivery, food supplements, nanoparticle synthesis and pharmaceutical formulation. However, there is little knowledge in nanoemulsion literature about controlling and predicting droplet size. In this article, we propose a scaling relation to predict the dependence of nanoemulsion droplet size with physical properties such as viscosity of the droplet phase and continuous phase, and process parameters such as input power density. We validate our proposed scaling with a wide range of droplet size data from nanoemulsions prepared with high pressure homogenization and ultrasonication. Our proposed scaling also compares favorably with experimental data from literature. The scaling relation can serve as a guiding principle for rational design of nanoemulsions.
