Abstract: An objective of the invention is to provide an oil-in-water emulsion cosmetic with a transparent to translucent appearance, that can stably and finely emulsify even a relatively large amount of a polar oil with a small amount of a surfactant. The oil-in-water emulsion cosmetic according to the present invention is characterized by containing (A) a non-ionic surfactant that has an HLB of 8 to 12; (B) a polar oil that is liquid at 25° C. and that has an IOB of 0.1 or higher; and (C) a water-soluble solvent; wherein the (A)/(B) ratio is 0.4 to 3.
