A stable FC emulsion is described. The FC emulsion of the present
invention comprises a continuous FC immiscible hydrophilic liquid phase
and a dispersed phase comprising FC suspended as droplets within the
continuous phase. The emulsion further comprises an emulsifying agent and
a stabilizing agent. The stabilizing agent of the present invention
reduces the ability of the FC droplets to move within the continuous
phase. The present invention also provides a method of making a FC
emulsion. The method comprises mixing an FC immiscible hydrophilic liquid
and a solid emulsifying agent by agitation at a temperature elevated
above the phase transition temperature of the emulsifying agent and below
the boiling temperature of the FC immiscible hydrophilic liquid, and
adding FC to the mixture of step (a) and agitating at the elevated
temperature to disperse droplets of FC in the FC immiscible hydrophilic
liquid to form the FC emulsion. The invention also provides another
method of making an FC emulsion, which does not require a solid
emulsifying agent. The method comprises mixing an FC immiscible
hydrophilic liquid and an emulsifying agent to form a first mixture;
mixing a stabilizing agent with the first mixture to form a second
mixture; and mixing FC with the second mixture to form a third mixture to
disperse droplets of FC in the FC immiscible hydrophilic liquid and to
form the FC emulsion, wherein the stabilizing agent reduces ability of
the droplets to move within a continuous phase of the FC emulsion.
