Particle Stabilization of Oil-in-Water-in-Air Materials: Powdered Emulsions

Authors


Abstract

Drops of a particle-stabilised oil-in-water emulsion are encapsulated in air by using hydrophobic silica particles. Such systems, termed oil-in-water-in-air powdered emulsions, show free-flowing behavior. Successful preparation of the material is achieved by preventing oil droplets from creaming and coalescing.
