Application - BVO (Brominated Vegetable Oil)

BVO (brominated vegetable oil) is used in the food industry as an emulsifier.  BVO is synthesized by the bromination of oleic acid.  Normally the density of a fatty acid is less than that of water, however upon brominating its density increases to about the same as waters density (~1 gm/mL).  Becasue BVO is not soluble in water it forms an emulsion and appears cloudy.  Typically only a few ppm (parts per million) is required.  It's what makes some soda pops appear cloudy.  BVO is prohobited in foods in some other countries.  The FDA still allows it in foods i the Unites States.
