Pickering nanoemulsions: An overview of manufacturing processes, formulations, and applications

There is an increasing demand for emulsions with low viscosity, a large fraction of dispersed phase, high transparency, or long shelf life. Emulsions consisting of nanosized dispersed droplets meet these criteria, but conventional nanoemulsions require large quantities of surfactants, some of which...
