Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder solid make-up cosmetic composition which has good usability and is excellent in the effect of holding makeup.

[0002]

2. Description of the Related Art Heretofore, various properties have been required for the function of makeup cosmetics. In particular, a lot of researches have been made in recent years as an important function especially for makeup retention. Conventional powder-solid makeup cosmetics are liable to sweat, sebum, or oil content of other cosmetics, which may cause makeup discoloration such as floating and runoff, and thus makeup must be frequently corrected. As a conventional technique for preventing such makeup deterioration and improving makeup retention, it has been known to incorporate a high-viscosity oil component in order to enhance the adhesion of the cosmetic to the skin.

[0003]

However, only by blending the above-mentioned high-viscosity oil component, the spreadability on the skin may be poor and stickiness may occur, which is not always satisfactory in terms of usability and prevention of makeup damage. It wasn't something.

[0004]

[Means for Solving the Problems] In view of such circumstances, the inventors of the present invention have conducted extensive studies and as a result, have found that in powder solid makeup cosmetics, a high aspect ratio having a specific aspect ratio to a specific high-viscosity dimethylpolysiloxane It has been found that by combining the powders in combination, it is possible to obtain a cosmetic having good makeup retention, smooth feel, and excellent usability, and has completed the present invention.

That is, the present invention has a viscosity of 1000 cs or more.
A high-viscosity dimethylpolysiloxane of 10000 cs was added to 0.2 .
The present invention relates to a powder solid make-up cosmetic , which comprises 5 to 10% by weight and 1 to 25% by weight of a high aspect ratio powder having an aspect ratio of 50 or more .

The structure of the present invention will be described in detail below. The high-viscosity dimethylpolysiloxane used in the present invention is represented by the following general formula (1).

[0007]

[Chemical 1]

The high-viscosity dimethylpolysiloxane of the above-mentioned general formula (1) used is usually classified by viscosity and is generally about 1000 to 10000 cs, but in the present application, it is 30.
Those of 00 to 10,000 cs are preferably used. 10
When it is 00 cs or less, the effect of the present invention cannot be exhibited, and when it is 10000 or more, usability tends to deteriorate.

The blending amount is 0.5% by weight to 10% by weight, preferably 1.0% by weight to 7.0% by weight. If the blending amount is less than 0.5%, the effect of the present invention is not sufficient, and if it exceeds 10.0% by weight, the meltability tends to be poor and caking may tend to deteriorate the usability. As a result of blending with this high-viscosity dimethylpolysiloxane and high-aspect ratio powder, a powder press-type makeup cosmetic having a smooth usability and a very long-lasting cosmetic effect can be obtained.

The high aspect ratio powder used in the present invention is a plate-like powder having an aspect ratio of 50 or more. The aspect ratio can be calculated from the value of major axis / thickness by measuring the thickness and major axis of 20 particles from an image obtained by a scanning electron microscope. Examples of the high aspect ratio powder include thinly peeled muscovite, phlogopite, synthetic mica (fluorinated phlogopite, potassium tetrasilicon mica, etc.), phlogopite, biotite, lithia mica, sericite, etc. The ore is coarsely crushed and then finely crushed. As the coarse crusher, a compression crusher, a shear crusher, an impact crusher, a roll type or a stamp type coarse crusher can be used. As the fine pulverizer, a ball medium mill, a stirring medium mill, a jet pulverizer, a wet high speed rotary mill, a stone mill type mill, etc. can be used.
It is not particularly limited to these. Further, after the pulverization, classification may be performed and the particle sizes may be adjusted appropriately. Classification is the natural sedimentation method,
The cyclone method or the like may be used. Before classification, or
Treatment such as acid treatment or heat treatment may be performed after classification. Among the above-described mica, synthetic mica (synthetic fluorine phlogopite, potassium tetrasilicon mica, sodium fluorine mica, etc.) is most preferable in terms of smooth usability and good adhesion.

In addition to mica, the high aspect powder has the effect of improving the makeup retention if it is plate-shaped, and examples thereof include metal oxides and metal sulfates. Titanium oxide,
Examples thereof include metal oxides such as zinc oxide, silica, iron oxide, and cerium oxide, and complex compounds of the above oxide metals. The method for producing these oxides or complex oxides can be obtained, for example, by applying a metal alkoxide aqueous solution on a smooth surface, scraping after drying, and firing. These high aspect ratio powders may be treated with silicone, fluorine, metal soap, fatty acid, surfactant, amino acid, dextrin fatty acid, or acids, alkalis, inorganic salts, and these Combined processing may be performed.

In the present invention, this aspect ratio is 5
0 or more is preferable. The upper limit of the aspect ratio is not particularly limited, and the effect tends to be more excellent as the aspect ratio is larger, but it is usually about 120 in manufacturing. Below 50,
It is difficult to obtain the effect of the present invention. The blending amount is usually 1 to 25% by weight based on the total amount of the cosmetic, preferably 2.0.
~ 15% by weight. If the amount is 1.0% by weight or less, the effect of the present invention cannot be sufficiently obtained, and if the amount is 30% by weight or more, the luster becomes excessive and the finish becomes unnatural, which is not preferable.

In addition to the above-mentioned essential components, the solid powder makeup cosmetic of the present invention contains a preservative, an antioxidant, a drug, a fragrance, an ultraviolet absorber, a moisturizer, etc. within a range that does not impair the effects of the present invention. Can be blended. However, the components are not limited to the above components as long as they are components usually used in the field of cosmetics.
