WATER TRANSFER WITHIN MULTIPLE W O/W EMULSIONS AT A FIXED SUBAMBIENT TEMPERATURE/

Differential Scanning Calorimetry of W/O/W multiple emulsions maintain ed at subambient temperatures has pointed out a water transfer from th e inner undercooled water phase towards the outer frozen aqueous phase . The water fluxes have been expressed considering irreversible thermo dynamics applied to the emulsions pictured as liquid membranes. The va lues of water transfer diffusion coefficients deduced from a solution- diffusion water transfer mechanism are in good agreement with predicte d values from the Stocke-Einstein Equation.
