Emulsions and foams are constantly in motion during production or transport. The interfaces of droplets or bubbles are stretched during these processes and the surface tension or interfacial tension responds to the stretching. The speed and degree of this response have an impact on the stability of food or personal care products and influence the yield in enhanced oil recovery (EOR). Interfacial rheology measurements with the DSA30R Drop Shape Analyzer give the relevant results for optimizing products and processes.
