Millimeter-sized silica-clay coated droplets were observed in oil-in-water (o/w) emulsions stabilized by two different particle types, hydrophilic fumed silica nanoparticles (0.007 µm, 0.0014 µm) and Cloisite 20A. Preparation of these silica-clay o/w emulsions demonstrated the possibility to influence droplet size and stability by varying the particle-particle ratio. Incorporating both inorganic and organic particles into o/w emulsions affords interesting pathways for controlling not only droplet size and stability but affinity for encapsulated substances, thereby suggesting interesting applications in the food, cosmetic, and pharmaceutical industries.
