Production, stability, and breaking of multiple emulsions . The production, stability and breaking of multiple emulsions are dependent on many factors, some of which are definable theoretically, some empirically. The stability of an emulsion is characterized by the interplay and superposition of interparticular interactive forces and rheological properties of the continuous phase. Interface‐active substances are adsorbed at the phase boundary and form an interfacial film, whose mechanical properties exert a strong influence on the stability of the droplets. Repulsive forces and interfacial film form an energy barrier. If this is overcome by increasing the thermal energy, by increasing the mobility of the particles or by external energy influences, the film breaks and the droplets coalesce. These processes are demonstrated theoretically and practically with the aid of individual methods of demulsification.
