title: A quantified analysis of the dielectric dispersion in a simple emulsion system.
abstract: The dielectric response of a simple, self emulsifying, system, based on a polysorbate and a medium chain length triglyceride, has been investigated as a function of the water content in the range 0 to 80% by weight. The low frequency capacitive dispersions have been characterised in terms of an electrode barrier layer dispersion, and the bulk conductance and capacitance have been quantified. It is shown that the barrier parameters are essentially insensitive to the water content, over concentrations from 2.5 to 75% by weight, and that the magnitude of the bulk emulsion conductance determines the form of the dispersions which can be observed.
