Nanoemulsions: Applications and Benefits
Nanoemulsions FAQ
What is a nanoemulsion?
Nanoemulsions are nano-sized emulsions, which are manufactured for improving the delivery of active pharmaceutical ingredients. These are the thermodynamically stable isotropic system in which two immiscible liquids are mixed to form a single phase by means of an emulsifying agent, i.e., surfactant and co-surfactant.
What are the properties of nanoemulsions?
In terms of physicochemical properties, nanoemulsions are positioned between microemulsions and traditional emulsions. The particle size range is between 30 and 100 nm which causes their typical blue-shining appearance. These small particle sizes prevent creaming, and, as a result, nanoemulsions often have satisfactory long-term stability.
How are nanoemulsions formed?
Nanoemulsions are formed when an emulsifier is involved in the mixture of two immiscible liquids to form stable but kinetic dispersions with droplet sizes and diameters of ≤ 100 nm and 20–200 nm, respectively.
What is the size of a nanoemulsion?
Nanoemulsions have droplets with diameter on the order of 100 nm. As the droplet size is significantly smaller than the wavelength of visible light, nanoemulsions are often transparent in appearance ( Fig. 8 ).
Are nanoemulsions kinetically stable?
Nanoemulsions are kinetically stable liquid-in-liquid dispersions with droplet sizes on the order of 100 nm. Their small size leads to useful properties such as high surface area per unit volume, robust stability, optically transparent appearance, and tunable rheology.
Why are nanoemulsions important?
Their small size leads to useful properties such as high surface area per unit volume, robust stability, optically transparent appearance, and tunable rheology. Nanoemulsions are finding application in diverse areas such as drug delivery, food, cosmetics, pharmaceuticals, and material synthesis.
