Experiments have been made with two kinds of O/W type emulsions. Compositions of the emulsions are shown in Table 1. The flow properties of these emulsions and their dispersion mediums have been studied in the range of low rates of shear. Effect of the flow properties due to addition of salts or lower alcohols are also observed. The two kinds of emulsions stated above, reveal different behaviours under shearing stress. One of them (emulsion I) reveals the Newtonian flow in the range of low dispersion concentrations. The other (emulsion II) behaves as the non-Newtonian fluid over all the range of concentrations. In the former, the dispersed particles may retain the dispersion state comparatively similar to that in the case of the static condition and this structure may be destroyed under shearing stress. This difference may be caused by the difference in the thickness and character of the hydration layer of the particles. These results may be well explained by assuming that the thickness and the character of hydration layer depend on the kind of the hydrophilic group of the emulsifying agent.
