• The object of this paper is to investigate the effect of the ratio of the viscosities of dispersed and continuous phases, μ<SUB>d</SUB>⁄μ<SUB>c</SUB>, on the particle-size distribution in o/w-type emulsions. The viscosity ratios (μ<SUB>d</SUB>⁄μ<SUB>c</SUB>) used were 0.836 : 1, 0.271 : 1, 0.0992 : 1, 0.0280 : 1, and 0.00133 : 1. The size of the dispersed liquid droplets was measured by the microphotographic method. The mean diameter and the particle-size distribution were determined, and, further, the specific interfacial energy was evaluated. When the viscosity ratio was much smaller than unity, the particle-size distribution showed a skewed curve. On the contrary, the specific interfacial energy increased remarkably as the viscosity ratio approached unity.
