The purpose of the present invention is to provide a water-in-oil type emulsion cosmetic that has a replenishing and smooth feel-of-use, that, once applied, forms a uniform coating, and that can minimize the appearance of skin roughness such as pores while covering discoloration such as spots and freckles, but that does not give an impression of a thick coating. The present invention provides a water-in-oil type emulsion cosmetic characterized by containing (A) 0.1-20 mass % of metallic soap-treated powder, and (B) a water-absorptive polymer having 0.01-2 mass % of a carboxyl group. The (B) water-absorptive polymer having a carboxyl group of this cosmetic preferably can absorb 10-1,000 times its own weight.

Water-in-oil emulsion cosmetic

An elastomer improves the feel of inorganic powder on the skin. An emulsion cosmetic is characterized by containing: (A) 0.5-20 mass % of an inorganic powder having an elastomer coating layer containing (a1) and (a2); and (B) 20-80 mass % of an oil component. The elastomer is characterized by comprising: (a1) a silicone polymer having an amino group; and (a2) a carboxyl group-containing silicone polymer or a carboxyl group-containing acrylic polymer, wherein the molar ratio of the amino group to the carboxyl group, Y/X is in the range of 0.1-1.2 (Y is the molar amount of the carboxyl group contained in the component (a2), and X is the molar amount of the amino group contained in the component (a1)).

Emulsion cosmetic

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/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.

Emulsion cosmetic containing titanium dioxide powder

A cosmetic having high portability including a liquid cosmetic impregnated in an impregnated body is provided, which is excellent in usability and cosmetic effects while keeping an ultraviolet light protection factor (SPF). A liquid cosmetic including an (A) ultraviolet light absorber in an amount of 1 to 10 mass %, and a (B) ultraviolet light scattering agent and a pigment grade titanium dioxide in an amount of 10 to 25 mass % is impregnated in an impregnated body. The liquid cosmetic is taken from the impregnated body by a finger or an applicator to be applied to the skin.
