Description
A water‑in‑oil‑in‑water emulsion created by nesting a secondary aqueous phase within a primary water‑in‑oil emulsion.
Technical
The primary W1/O emulsion is stabilized by lecithin or polysorbate 80, which lowers interfacial tension and yields 1–5 µm droplets at 25–30 °C under high shear. Adding a second aqueous phase (W2) and re‑homogenizing at 20–25 °C creates larger 10–50 µm droplets, encapsulating water within oil droplets that are themselves dispersed in water. Precise control of temperature, emulsifier concentration (≥0.5 %), and shear prevents coalescence, oxidation, and phase inversion.
Science
Primary Reaction
