Cryo-sem images of multilayer lamellar vesicles made from a mixture of stearic acid
(50% by weight) and palmitc acid (50% by weight). The neutralisation degree is 33%
with TEA and the total surfactant concentration is 20% by weight.
10 µm
Cryo-sem image at 2 hours storage time
10 µm
Cryo-sem image at 18 hours storage time
The images show that the vesicles are more stable than those made using pure stearic
acid.
