Thermodynamically Stable Droplet size 10 - 100 nm (transparent) High surface area: 200 m2/g Ultra Low O/W IFT (10-2 – 10-3 mN/m) W/O , O/W and Bicontinuous types Forms at CPP = 1 |
Kinetically Stable 1-10 mm (opaque) Low surface area: 15 m2/g O/W IFT 1-10 mN/m W/O or O/W types Forms at CPP > or < 1 |
