The present invention relates to a cosmetic composition in which a W/O (water-in-oil) cosmetic composition with low viscosity is packaged in an airless container, and more specifically, to a cosmetic composition with low viscosity which enhances the stability of easily-separable low viscosity materials and improves user convenience by impregnating the W/O cosmetic composition with low viscosity into a urethane foam and packaging the composition in the airless container.
