An objective of the present invention is to provide an external preparation for concealing roughness that is easy to spread when applied, while also having effects of concealing roughness such as fine wrinkles. The external preparation for concealing roughness of the present invention comprises (a) 1% to 15% by mass of a wax; and (b) 4% to 25% by mass of a non-spherical powder; and has a viscosity of 50,000 to 150,000 mPa·s.

External preparation for concealing roughness

A low-viscosity water-in-oil cosmetic emulsion preparation gives a smooth use feeling, lightly spreads when applied, and has excellent dispersed-powder stability. The cosmetic emulsion preparation has (A) a polar oil which is liquid at 25&#xb0; C. and has an IOB value exceeding 0.1, (B) a hydrocarbon oil, (C) a polyoxyalkylene; and alkyl-modified organopolysiloxane represented by general formula (I), and (D) a powder surface-treated with both an N-acylamino acid and methylpolysiloxane. (In formula (I), R represents a hydrogen atom or a C1-5 alkyl group, x is an integer of 5-50, y is an integer of 1-30, z is an integer of 20-200, a is an integer of 2-20, b is an integer of 1-5, c is an integer of 2-20, and d is an integer of 0-20). 

Water-in-oil emulsion cosmetic

The purpose of the present invention is to provide a water-in-oil emulsified solid cosmetic having a relatively high internal-aqueous-phase proportion (about 40% or higher), the cosmetic being a makeup which has an excellent concealing effect and gives a natural finish and which is stable and has satisfactory applicability. The present invention relates to a solid cosmetic in water-in-oil emulsified type characterized by comprising (A) at least one fatty acid glyceryl ester selected from the group consisting of glyceryl isostearate, poly(2-glyceryl) diisostearate, and glyceryl oleate, (B) an aqueous component, (C) an oily component, and (D) a powdery component, the oily component (C) comprising a solid oil (C1) and an oil-soluble film former (C2) and the powdery component (D) comprising titanium dioxide (D1) having a primary-particle diameter of 0.05-0.5 &#x3bc;m in an amount of 10 mass % or more relative to the whole cosmetic preparation and further containing a pearl pigment (D2).

Water-in-oil type emulsification cosmetic

Provided is an elastomer that improves the skin feel of an inorganic powder. The elastomer according to the present invention is an elastomer comprising: (A) an amino group-containing silicone polymer; and (B) a carboxyl group-containing silicone polymer or a carboxyl group-containing acrylamide polymer, wherein a molar ratio Y/X between amino groups and carboxyl groups is within a range of 0.1 to 1.2, wherein Y denotes the molar amount of carboxyl groups contained in the component (B), and X denotes the molar amount of amino groups contained in the component (A).

Elastomer

The present invention provides a water-in-oil type emulsion cosmetic which has a fresh and smooth feeling to the touch; forms a uniform coating film once applied; can make skin unevenness such as pores look less prominent while covering discolorations such as age spots and freckles; and does not give an impression of thick application. The water-in-oil emulsion cosmetic is characterized by including (A) 0.1-10% by mass of a pigment-grade titanium dioxide and (B) 0.01-2% by mass of sodium acrylate grafted starch. It is preferred that this cosmetic further includes (C) spherical particles and/or (D) a silicone elastomer.

Water-in-oil type 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.

Cosmetic including liquid cosmetic impregnated into impregnated body

The present invention provides a water-in-oil emulsion solid cosmetic that is further improved in terms of an excellent feeling in use (good spreadability and fresh feeling (texture)) obtained by incorporating a powder in a water phase, and that also has sufficient covering ability, stability even at high temperature, and long-lasting property. The present invention provides a water-in-oil emulsion solid cosmetic comprising an external oil phase comprising a liquid oil thickened or solidified with (A) wax and (B) disteardimonium hectorite, and an internal water phase comprising (C) an internal phase powder dispersed in an aqueous medium.
