Question

A class of these materials is commonly formed via the addition of octenyl-succinic-acid-derivatized starch granules. “Double” examples of these materials, known as O/W/O (“owo”) or W/O/W (“wow”), are commonly used as vaccine adjuvants due to their increased activity. Types of these materials stabilized by solid particles are named for either Ramsden or Pickering. The presence of essential (15[1])oils can cause the spontaneous formation of these materials in the (*) ouzo (“OO-zo”) effect. Low-pressure methods of (-5[1])forming (-5[1])these materials, such as by forcing a phase through a membrane, (-5[1])are replacing high-pressure (10[1])methods such as homogenizers. (-5[1])These materials (-5[1])can be stabilized by amphiphilic surfactants, (10[1]-5[1])such as egg yolk lecithin in mayonnaise. (10[1])These materials (-5[1])can be destroyed by buoyant forces in creaming and by droplet flocculation. (10[1])For 10 points, name these colloids that are mixtures (10[1])of two immiscible liquids. ■END■ (10[5]0[2])
