Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a multilayer makeup cosmetic composition in which a makeup base material is used for the first layer and a makeup finish material is used for the second layer, which is particularly suitable for concealing skin troubles. Regarding

[0002]

2. Description of the Related Art Conventionally, azams made with makeup cosmetics,
For the concealment of so-called skin troubles such as spots and freckles, sunscreens and the like, those containing titanium dioxide which is a white pigment are mainly used.

However, such titanium dioxide makeup cosmetics have a limited hiding power (or light-shielding power) and are effective for mild skin troubles, but for severe skin troubles. Is not very effective and, on the contrary, may make the affected area more noticeable. In addition, since it is thick, a natural finish cannot be obtained, which is often a problem.

For example, in the case of pigmented troubles such as severe bruising and severe liver cirrhosis, the concealing power of conventional titanium dioxide cosmetics causes the transmission of transmitted light even if there is scattering of transmitted light in the foundation layer. Part of the skin reaches the skin, and the reflection from the pigmented part, which is the affected part, cannot be escaped, and the skin trouble can be seen at a glance. There is also a problem that the adhesion and the durability are still insufficient.

On the other hand, JP-A-2-304015 proposes a makeup cosmetic containing aluminum powder and a film-forming agent. The aluminum powder used in this makeup cosmetic has excellent hiding power, but on the finish, it gives a thick makeup feeling and is unnatural.
It has a problem of impairing the skin feeling.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the above problems and provide a make-up cosmetic composition which is excellent in adhesiveness and durability in addition to the ability to conceal skin troubles and has a good finish. And

[0007]

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems, the present inventors applied a makeup base material containing an adhesive substance to the affected area having skin troubles. When a make-up finish containing a layer of aluminum powder is applied as a second layer thereon, a coating film having excellent hiding power due to the effect of shielding light and having improved adhesion, durability and finish can be obtained. This has led to the completion of the present invention.

[0008] That is, the present invention provides a multilayer makeup cosmetics in which a first layer make-up base material containing an adhesive substance and a second layer make-up finish material containing aluminum powder are combined. ..

The present invention will be described in detail below. First, the makeup base of the present invention is used for the first layer which is applied directly to the skin. This make-up base material contains a sticky substance. The adhesive substance not only adheres to the first layer, but also improves the adhesion, adhesion and durability of the aluminum powder used for the second layer on the first layer, and also provides a thin and light-shielding makeup. It is used for the purpose of forming a film and preventing deterioration of skin feeling.

As the adhesive substance, any substance used in ordinary cosmetics may be used.
When tested by the method specified in IS Z-0237, the following performance tack: 5-20 Adhesive strength (stainless steel plate): 500-2000 g / 25 m
m. This adhesiveness test method will be described in more detail. A sample of an adhesive substance is applied to a release paper, dried, attached to a coated paper, and then the release paper is peeled off to give an adhesive tape, which is kept at room temperature (25 ° C). ) And perform the test according to the following method. (Test method) Tack: Tack according to the test method specified in JIS Z-0237 Adhesive force: Adhesive force according to the 180-degree peeling method specified in JIS Z-0237 (g / 25 mm) (Substrate: Stainless plate) Specific examples of such an adhesive substance include a polymer obtained by copolymerizing an acrylic acid ester as a main component monomer with a polymerizable carboxylic acid (hereinafter referred to as an acrylic copolymer); a three-dimensional reticulated silicone or the like. Can be mentioned.

To explain these adhesive substances in more detail, first, an acrylic copolymer is obtained by copolymerizing 1 to 10% by weight of a polymerizable carboxylic acid with an acrylic ester, and its average molecular weight is 10,000-10
It is about 0,000.

Examples of the acrylate ester include methyl acrylate, ethyl acrylate, propyl acrylate,
Examples thereof include butyl acrylate, isobutyl acrylate, hexyl acrylate, and 2-ethylhexyl acrylate, and these can be used alone or in combination of two or more.

As the above-mentioned polymerizable carboxylic acid, an unsaturated carboxylic acid having a low carbon number can be mentioned, and acrylic acid, methacrylic acid, itaconic acid, maleic acid and the like can be preferably exemplified. These can be used alone or in combination of two or more.

In addition to the acrylic ester which is the main component monomer, one or more of vinyl acetate, methyl methacrylate, and acrylamide may be used as a subcomponent monomer. Similarly to the above, a polymer having an average molecular weight of 10,000 to 1,000,000 obtained by copolymerizing a main component monomer and a subcomponent monomer with 1 to 10% by weight of a polymerizable carboxylic acid based on the total amount of these monomers is used. In this case, the weight ratio of the main component monomer and the sub-component monomer is 99: 1 to 7
It is preferably 0:30.

Commercially available acrylic copolymers are, for example, SE-753 sold by Taisei Kako Co., Ltd.
A, there is 3LX-174. Next, the three-dimensional reticulated silicone can be obtained, for example, by hydrolyzing an organic trichlorosilane (RSiCl ₃ ) and an organic dichlorosilane (RSiCl ₂ ), then condensing and crosslinking. Examples of commercially available products include Silicone KF7613B manufactured by Shin-Etsu Chemical Co., Ltd.

The content of the above-mentioned adhesive substance is usually about 0.5 to 70% by weight based on the total amount of the makeup base material. In addition, the make-up base material may contain a diluent, a moisturizing agent, an antiseptic agent, a perfume and the like which are commonly used in cosmetics. On the other hand, the makeup finishing agent of the present invention is used for the second layer (foundation) applied on the first layer composed of the makeup base material. This make-up finish contains aluminum powder. Aluminum powder is used for the purpose of improving the hiding power of skin troubles. The content of the aluminum powder is usually 5 to 40% by weight, preferably 10 to 30% by weight, based on the total amount of the second layer make-up finish.

If the aluminum content in the second layer is less than 5%, the hiding power may decrease. When the content is 40 to 100%, a normal finishing foundation is applied as a third layer on the second layer for use.

The average particle size of the aluminum powder is usually 10 to 70 μm, preferably 2 to 50 μm. If the average particle size is less than 10 μm, dullness may occur in the aluminum powder itself, which may be unacceptable in terms of cosmetic finish, and if it exceeds 70 μm, a rough feeling may occur and a discomfort may be felt.

Other make-up finishes include various powders of organic, inorganic and pearlescent agents used in ordinary make-up finishes; pigments; solid, semi-solid or liquid oils; surfactants; pigment dispersions. Agents, plasticizers, fragrances, preservatives and the like may be contained in amounts that do not reduce the hiding power.
