The average droplet size of nanoemulsions, a type of emulsion, ranges from 20 to 200 nanometers. A system of two immiscible liquids, such as oil and water, is stabilised by the addition of an emulsifying agent to form an emulsion. As their name suggests, nanoemulsions include particles on the nanoscale, giving them a high surface area-to-volume ratio ...

Nanoemulsion is the major vehicle for delivering different types of drugs, nucleic acids, and imaging agents. Due to their attractive properties, it has been extensively used for diagnostics of cancer therapy and imaging. However, nanoemulsion is designed through multiple functions by modifications in surface and encapsulation of active compounds ...

A nanoemulsion is an emulsion with droplet size of 100 nm or less. The emulsifiers used in nanoemulsions include non-ionic emulsifiers such as polysorbates and sucrose esters, Zwitterionic emulsifiers such as lecithin, and food polymeric emulsifiers such as starch sodium octenyl succinate (OSA - starch).

On the growth mechanisms of nanoemulsions
Journal of Colloid and Interface Science, 2013The shelf stability of nanoemulsions made by ultrasound, phase inversion composition, and the Ouzo effect was studied using a range of hydrocarbons, as the model oils, and surfactants. The cube of the average drop radius of the nanoemulsions displayed a linear increase with time. Both Ostwald ripening and coalescence can exhibit such behaviour.

Due to transparency at high droplet volume fraction, improved bioavailability or diffusion levels and improved pharmaceutical shelf-life, nanoemulsions have the potential in pharmaceutical industries. Nanoemulsions are thermodynamically stable structures of colloidal dispersion consisting of two immiscible liquids combined with emulsifiers (surfactants

Structure of concentrated nanoemulsions
The Journal of Chemical Physics, 2005We use extreme shear to create a dispersion of nanoscale droplets of silicone oil in an immiscible water phase containing an anionic surfactant sodium dodecylsulfate. Using centrifugal size fractionation, we obtain nanoemulsions having a well-defined average radius of a=75nm.

Surfactant Partitioning in Nanoemulsions
Langmuir, 2018Using a fractionated silicone oil-in-water nanoemulsion (NEM), which has a high ratio of surface area-to-volume, we investigate surfactant partitioning between the bulk continuous phase and the adsorbed interfacial phase. By adjusting the droplet volume fraction of this fractionated NEM and by using gravimetric and electrical conductivity methods, we ...

Emulsions have wide applications in the food industry, and nanoemulsions, which have a smaller size and exhibit prominent physicochemical properties, have also attracted much attention and gained increasing use in various food sections. Emulsions and nanoemulsions are thermodynamically unstable systems, and it is, therefore, critical to select ...

Expert Opinion on Drug Delivery, 2016
The efficacy of many hydrophobic bioactives (pharmaceuticals, supplements, and nutraceuticals) is limited due to their relatively low or highly variable bioavailability. Nanoemulsions consisting of small lipid droplets (r < 100 nm) dispersed in water can be designed to improve bioavailability.The major factors limiting the oral bioavailability of ...
