Emulsion cosmetic containing titanium dioxide powder

An emulsion cosmetic maintains a concealing ability, allows light in a long wavelength region to transmit efficiently (i.e., an excellent red light selective transmit function), is spread easily, wherein a powder likeness cannot be felt upon use, and provides a natural finish when applied onto the skin. A titanium dioxide powder therefore is composed of particles having an apparent average particle diameter of 100 nm or more and less than 500 nm, an average crystallite diameter of 15 to 30 nm as measured by a X-ray diffraction method and a specific surface area of 10 to 30 m.sup.2/g, and each has a shape with radially projected needle-like projections are coagulated, and has a ratio of a longer axis to a shorter axis (i.e., a (longer axis)/(shorter axis) ratio) in the shape of 1.0 to 2.5. The emulsion cosmetic contains 0.1 to 25% by mass of the titanium dioxide powder, 0.1 to 5% by mass of disteardimonium hectorite and 0.1 to 8% by mass of a silicone surfactant.
