Many of the materials we use each day are structured fluids.
Most foods, cosmetics, pharmaceuticals and paints contain
particles or droplets of an immiscible fluid suspended in a
carrier liquid. A number of soft semisolid materials also fall
under the category of structured fluids since they have a
multiphase structure and exhibit complex flow behavior.
Some examples would be cheeses, lipstick, caulk, and bread
dough.
