Emulsion stability basics Processing Magazine

An increase in continuous phase viscosity will greatly improve emulsion stability by retarding the inevitable rise of the oil droplets to the top In most circumstances this more stable finished product is the overriding concern and a decision to gain this advantage at the expense of overcoming a higher interfacial tension in the mechanical processing step is gladly accepted
