Nanostructured novel carrier for topical application

Nanoemulsions have attracted considerable attention in recent years for application in personal care products as potential vehicles for the controlled delivery of cosmetics and the optimized dispersion of active ingredients in particular skin layers. Of the many techniques that have been developed to measure droplet size of emulsions, 2 are of interest: laser light scattering and energy-filtering transmission electron microscopy used to measure the size of droplets in a nanoemulsion formed by a novel emulsifying agent that is able to spontaneously create emulsions with droplet sizes smaller than 300 nm.
