Structure and stability of W/O/W emulsions as influenced by WPC and NaCl in inner aqueous phase.

Effect of WPC and NaCl in internal aqueous phase (W) of W/O/W type double emulsions was studied. Pre-emulsion and final emulsion were prepared using microfluidizer and Ultra-Turrax high shear mixer, respectively. The emulsions prepared using salt exhibited uniform droplet size distribution and structural integrity.
