emulsiomien

Emulsiomien are a class of hierarchical emulsions in colloid science, characterized by droplets of one immiscible liquid contained within droplets of another immiscible liquid, forming nested structures such as water-in-oil-in-water (W/O/W) or oil-in-water-in-oil (O/W/O).

They are typically produced by sequential emulsification steps, membrane emulsification, or advanced microfluidic methods that generate nested droplets with controlled sizes. Stabilization is achieved with surfactants, interfacial polymers, or solid particles (Pickering stabilization), often in combination to reduce coalescence between phases.

Key properties include droplet size distribution, interfacial area, rheology, and stability under temperature and shear. Emulsiomien can exhibit unique optical and transport properties due to multiple interfaces, and are susceptible to coalescence, Ostwald ripening, and phase leakage if stabilizers are inadequate.

Applications are speculative but include controlled delivery of active ingredients in pharmaceuticals, encapsulation of flavors or fragrances in foods, cosmetic emulsions with layered release, and the synthesis of advanced materials where multi-layered confinement is advantageous.

The term emulsiomien is uncommon in mainstream literature and often appears in theoretical discussions of multi-phase emulsions. It is sometimes used in fictional or speculative contexts to describe nested emulsions. See also emulsions, double emulsions, and Pickering stabilization.
