7. Discuss the two types of emulsions

A. Oil-in-water emulsions are conventionally defined as a thermodynamically unstable systems which
include two immiscible liquids (generally water and oil), in which oil is distributed into the water. 
B. Water-in-oil emulsions one phase is mixed into the other. In other words, one liquid serves as a sort
of base into which another liquid is added. When an emulsion is “oil-in-water,” oil is the dispersed phase
that is distributed into the continuous phase, water.
