The present invention 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.
