Nanoemulsions: What it is, Applications, Advantages and Processing
Nanoemulsions are formed by mixing two immiscible liquids, typically oil and water, into a stable emulsion with droplet sizes ranging from 20 to 200 nanometers. These droplets are significantly smaller than those found in traditional emulsions, giving nanoemulsions unique properties. They are kinetically stable and have a high surface area per unit volume, making them useful in various applications such as drug delivery, food products, cosmetics, pharmaceuticals, and materials science. Inner Structure of Nanoemulsions Properties: Nanoemulsions exhibit unique properties due to their small droplet size, which include: Enhanced Stability: The small size of the droplets reduces the likelihood of coalescence and phase separation, leading to longer shelf life. Increased Bioavailability: The large surface area of the tiny droplets allows for better absorption of active ingredients by the body. Optical Clarity: Unlike traditional emulsions, nanoemulsions can be clear or slightly hazy, maki
