The apparent viscosity of stable emulsions has been measured and evaluated. The systems studied consisted of various oil in water emulsions, utilizing a series of six n-paraffins from heptane to octadecane. The system was stabilized with a conventional emulsifying agent. The apparent viscosity of these emulsions was studied in relation to (a) the concentration of the disperse phase and, (b) the viscosity of the hydrocarbon used as the continuous phase.
It was established that the volume concentration of the disperse phase had considerable effect on the apparent viscosity of the emulsion. An increase in the concentration of the disperse phase resulted in. an increase of the apparent viscosity.
It was also shown that the viscosity of the hydrocarbon comprising the contiguous phase had considerable effect upon the apparent viscosity of the emulsion. The increase in apparent viscosity was still greater than the increase in the viscosity of the external phase. This shows that an interaction of effects exists between the concentration of the disperse phase and viscosity of the external phase.
An equation was developed which related apparent emulsion viscosity and concentration of the disperse phase with type and concentration of emulsifier as the correlating parameter.
