Water-in-Oil (W/O) emulsions are widely used in cosmetics. However, O/W (Oil-in-Water) emulsions are generally superior to W/O emulsions in terms of stability. In this study, we investigated the changes of viscosity, the size of emulsion droplets, and rheological properties of emulsions prepared using distearyldimonium chloride (DDC), magnesium aluminum silicate (MAS) and quaternium-18 hectorite (QH). In addition to the changes of the composition, we tested the condition of homogenization including rotation per minute of the mixer and the mixing time. The viscosity of emulsions with DDC and AMS were not changed with time and the stability of emulsions was stable during the storage time. However, the fluidity of emulsions were low due to the forming gel network in the emulsions. The gelling power of the emulsions with QH was rather weaker than that of the emulsions with DDC and MAS. The viscosity of emulsions with QH was gradually reduced and the phase separation of emulsions with high concentration of oil was observed throughout the storage time, however, the stability of emulsions with DDC, MAS and QH was excellent, the fluidity of emulsions was enhanced, and the viscosity of emulsions was sustained for a long time after setting of emulsions.
