heal.abstract	Stable paraffin oil-in-water (OW) emulsions with Tween 20 (polyoxyethylene sorbitan monolaurate) as emulsifier have been prepared over a wide range of concentration. The dielectric behaviour of the emulsions has been studied by the depolarisation thermocurrent (DTC) method in the temperature range 85-250K, to obtain information about the state of water in the emulsion. Four peaks, numbered I-IV, have been observed at temperatures of about 120, 135, 210 and 235K respectively. The DTC peaks I and II have been attributed to the reorientation of free and bound or hydration H2O molecules in the emulsion respectively. Evidence has been obtained that DTC peaks III and IV are due to Tween 20.	en
