We developed an oil‐based make‐up remover still having a cleansing function even in a bath by utilizing polygycerol fatty acid esters, which are widely used in food industry fields. The polyglycerol fatty acid esters that have superior self‐emulsification were synthesized by adjusting the molar ratio of fatty acids and polyglycerols. The phase diagrams were constructed to recognize the cleansing mechanism. In the phase diagram of a water/surfactant/oil system, W/O type microemulsion that solubilizes a small amount of water forms near the surfactant‐oil axis. Regarding the washing process as proceeding from surfactant‐oil axis toward water vertex in the phase diagram, it is supposed that this is the reason why the ordinary remover cannot be used in the presence of water. It was found that the amount of solubilized water could be increased by adding middle‐chain alcohols as co‐surfactants in the present system. By utilizing a polyglycerol ester of the middle‐chain fatty acid instead of such alcohols, the amount of water dissolving in the microemulsion remarkably increased like the added alcohol system. Consequently, the make‐up remover containing the polyglycerol ester of the middle‐chain fatty acid could be used even in a bath, and easily removed the oil soil, dispersed in water as fine emulsion droplet.
