Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic for skin which has reduced makeup collapse and makeup loss due to perspiration, such as a makeup cosmetic containing a glossy plate-like powder.

[0002]

2. Description of the Related Art Conventionally, as one of makeup methods for making the face and neck circumference, and arms and feet look beautiful, there is a method of applying beautiful powder to the skin to give a beautiful shine. Heretofore, fish scale foil collected from natural fish has been used as this brightener, but this is expensive because of natural products, and its quality varies. On the other hand, luster pigments collected from minerals such as mica have the advantage of being inexpensive and readily available.However, since they have problems with color stability, it is difficult to impart gloss uniformly and beautifully to the skin. difficult. Therefore, aluminum (Japanese Patent Laid-Open No.
9-94714), iron oxide (JP-A-51-179).
No. 10) and titanium (Japanese Patent Application Laid-Open No. 51-143027) have been proposed in which a metal film is formed to improve the glossiness. But these were not satisfactory either.

[0003] As a new brightener instead of the above-mentioned gloss pigment, there is one obtained by cutting a film-like polymer obtained by laminating two or more kinds of resins in multiple layers into powder. This was colored with metals such as aluminum and iron oxide yellow, or legal dyes in order to impart various colors to the gloss (Japanese Patent Application Laid-Open No. 59-118704). Since these can obtain powders of various particle diameters depending on the cutting width, they have unprecedented glossiness and can be supplied in a stable and uniform product as appropriate, so they have been applied in a wide range of fields. . That is, in addition to makeup cosmetics for the skin of the face and body, it is used as a nail polish or a brightener for hair makeup agents for hair (Japanese Patent Publication No. 230004/1990).

[0004]

The characteristics of the glossy plate-like powder are as follows: the quality does not vary, the uniformity is high even when blended into a product, and after coating on the skin, That is, uniform gloss can be provided. However, this has a problem that it is easily affected by sweat generated by perspiration as compared with other brighteners, becomes uneven on the skin surface, and easily peels off from the skin.

On the other hand, spreaders have been frequently used in the past to improve the adhesion of makeup cosmetics to the skin. Conventionally, metal soap has been frequently used as a spreading agent, but recently, fatty acids, higher alcohols, silicone derivatives and the like have been used (JP-A-61-103814). Examples include liquid paraffin, squalane, petrolatum, castor oil, isopropyl myristate, isopropyl palmitate, stearic acid, oleic acid, methylpolysiloxane, methylphenylpolysiloxane, decamethylcyclopentasiloxane, and the like. In this case, a silicone derivative is preferably used from the viewpoint of adhesion and ease of compounding. As a method of using the spreading agent, there are a method in which the spreading agent is directly blended into the cosmetic, and a method in which the spreading agent is impregnated or covered with a powder or the like in advance. However, the method using these spreading agents is not sufficiently effective in improving the adhesion of the film-shaped resin plate powder.

[0006] In order to absorb perspiration and reduce the influence of perspiration, a composition containing a superabsorbent polymer has been proposed, but it is satisfactory in terms of usability and sustainability of the effect. No. (JP-A-60-81120).

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and reduces makeup collapse and makeup loss due to sweating of a cosmetic containing a glossy plate-like powder, and reduces the effects of the glossy plate-like powder for a long time. An object of the present invention is to provide a skin cosmetic that can be stably exhibited.

[0008]

Means for Solving the Problems and Embodiments of the Invention The present inventors have conducted intensive studies to achieve the above object, and as a result, have found that a skin cosmetic containing a glossy plate-like powder is
By blending the antiperspirant active ingredient, the unevenness of the plate-like powder is reduced, the peel-off of the glossy plate-like powder after make-up is prevented, and excellent skin adhesion persistence is provided.
The inventors have found that the makeup effect can be maintained for a long time, and have accomplished the present invention.

Hereinafter, the present invention will be described in more detail.
The cosmetic for skin of the present invention is a combination of a glossy plate-like powder and an antiperspirant active ingredient.

The glossy plate-like powder used in the present invention includes polyethylene terephthalate / aluminum / epoxy laminated powder, polyethylene terephthalate / polyolefin laminated powder, polyethylene terephthalate / polymethyl methacrylate laminated powder, polyethylene terephthalate / gold laminated powder. Powder, polyethylene / polyester laminate powder, polyethylene / polyethylene terephthalate laminate powder, and the like.

These plate-like powders are obtained by laminating two or more kinds of resins in multiple layers, the number of layers is 2 to 300, and the average thickness is in the range of 0.005 to 0.1 mm. Is preferred. A plate-like powder having a thickness smaller than this range may not be able to be uniformly attached to the skin. On the other hand, with a plate-like powder having a thickness exceeding this range, the powder tends to peel off from the skin and may give a rough feeling. These plate-like powders have an average major axis of 0.01 to 2.
A rectangular, circular or elliptical shape having a range of 0 mm, preferably 0.1 mm or less is preferable. With a plate-like powder having an average major axis smaller than 0.01 mm, satisfactory gloss may not be obtained in some cases. On the other hand, the average major axis is 2.
A plate-like powder larger than 0 mm can sufficiently impart gloss, but cannot provide uniform and beautiful gloss and may give a rough feeling.

[0012] By passing these materials through a filter, a powder having a small particle size distribution can be obtained.

These plate-like powders can also be obtained from commercial products. For example, DC glitter and iridescent glitter manufactured by Diachemco Co., Ltd. may be mentioned. The DC glitter is made of polyethylene terephthalate / aluminum / epoxy laminated powder, and uncolored silver C and gold I colored with yellow iron oxide are commercially available. Silver C has three layers and Gold I has four layers, each having a thickness of about 15 μm.
It is. The iridescent glitter IF4101 is made of a rectangular powder composed of a laminated powder of polyethylene terephthalate and polyolefin, the number of laminated layers is 113, and the thickness is about 18 μm. Both are 0.1mm, 0.15mm,
What passed through the mesh of 0.3 mm and 0.4 mm diameter is marketed.

The amount of the above-mentioned platy powder can be arbitrarily set according to the purpose, but is preferably 0.01 to 20% by mass, and more preferably 0.1 to 5. 0
% By mass is desirable.

On the other hand, the antiperspirant active ingredients used in the present invention include chlorohydroxyaluminum, aluminum chloride, allantoin / aluminum derivative, aluminum sulfate, aluminum potassium sulfate, aluminum / zirconium chlorohydrate / glycine complex, aluminum phenol citrate Aluminum sulfonate, aluminum β-naphthol disulfonate, p
-Zinc phenolsulfonate, zinc oxide, lead acetate, sodium perborate and the like.

The amount of the compound varies depending on the effective antiperspirant component, but is preferably 0.05 to 30% by mass. 0.05
If the amount is less than mass%, the antiperspirant effect may not be expected for any of the components. On the other hand, if it exceeds 30% by mass, a sticky feeling may occur during use.

Further, to the cosmetic for skin of the present invention, metal soap, fatty acid, higher alcohol, silicone derivative or the like may be added as a spreading agent for the purpose of enhancing spreadability. Examples include liquid paraffin, squalane, petrolatum, castor oil, isopropyl myristate, isopropyl palmitate, stearic acid, oleic acid, methylpolysiloxane, methylphenylpolysiloxane, decamethylcyclopentasiloxane, and the like. Preferably, a silicone derivative is desirable from the viewpoint of adhesion and ease of compounding.

The preferred compounding amount is 0.1 to 20% by mass. If the amount is less than 0.1% by mass, the spreading effect cannot be sufficiently expected. If the amount exceeds 20% by mass, a sticky feeling may be caused.

The skin cosmetic of the present invention can be prepared in various dosage forms such as a roll-on type, an aerosol type, a stick type, a spray type, a powder type, a gel type, a cream type, a lotion type, and the like. And various kinds of skin cosmetics, especially make-up cosmetics, can be prepared by a conventional method. In addition, make-up cosmetics for facial skin are eyebrows,
