[0002]

2. Description of the Related Art Cosmetics, especially make-up cosmetics, are cosmetics for dressing the skin beautifully. For such purposes, the color rendering effects of powders and coloring agents are used to make the actual skin. A cosmetic film with high color rendering properties is created on the top to make the skin look beautiful. The most problematic in such cosmetics aiming at the color rendering effect is the change over time of the decorative film that realizes the color rendering effect. Such changes over time include, for example, phenomena such as dull makeup, declining makeup, and exposing the skin. Among them, it has been known that dullness can be considerably suppressed by hydrophobizing the powder or using a composite powder, and exposure of the background can also be reduced by surface treatment of the powder or use of an oil agent with high adhesion. Is being overcome. However, due to excessive secretion of sebum,
At present, no measures have been taken for shininess caused by the excessive presence of oily components on the skin.

On the other hand, no cosmetics for preventing shine are known in the field of cosmetics, and it is not known at all that a combination of a translucent powder and silicone oil is extremely useful for preventing shine. Was.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION (1) Translucent powder which is an essential component of the shine cosmetic of the present invention The shine prevention cosmetic of the present invention is characterized by containing a translucent powder. . The translucent powder referred to in the present invention is 1
It means a powder having a transmittance of about 0 to 60%, which is hardly transparent, but not a light-transmitting material. Specifically, silica, methylsiloxane network polymer, crosslinked methylpolysiloxane, silicic acid-related compounds such as calcium silicate and magnesium silicate, polyamide compounds such as nylon powder and silk powder, acrylic acid, methacrylic acid and esters of these Preferred examples include acrylic resin powders such as polymers and copolymers, acrylic resin powders, methylsiloxane network polymers,
One or more kinds selected from crosslinked methylpolysiloxane powder, nylon powder and silk powder can more preferably be exemplified. For acrylic resin powder,
A hollow type having a blank inside is particularly preferable. The preferred content of the translucent powder in the anti-glare cosmetic composition of the present invention is 5 to 40%, more preferably 10 to 30% by weight. This is because if the amount is too small, the anti-glare effect may not be exhibited, and if the amount is too large, such effects may not only reach a plateau but also impair the flexibility of prescription.

(2) Silicone oil which is an essential component of the anti-glare cosmetic of the present invention The anti-glare cosmetic of the present invention contains silicone oil as an essential component. In the present invention, the term "silicone oil" is a general term for oregano silicone having a fluidity at 25 ° C. and 1 atm. Specifically, it has a linear, branched or cyclic structure. Particularly preferred are silicone oils commonly used in cosmetics such as alkylpolysiloxanes and alkylphenylpolysiloxanes. These silicone oils may contain only one kind or two or more kinds in combination. As a preferred embodiment, it is preferable to include a combination of a so-called volatile silicone oil having a boiling point of 200 ° C. or less at 1 atm such as decamethylcyclopentasiloxane and a silicone oil which hardly volatilizes at 25 ° C. at 1 atm. . Particularly preferred in such a combination is a combination of volatile silicone and phenylmethylpolysiloxane, the ratio of which is volatile silicone: nonvolatile silicone = 2: 1 to 1
The ratio is preferably 1: 4, more preferably 1: 1 to 1: 2. This is because if the amount of the volatile silicone is too large, the finish may be too powdery to impair the finish, and if the amount of the non-volatile silicone oil is too large, the antiglare effect may be impaired. The preferred content of these silicone oils in the anti-glare cosmetic of the present invention is 10% in total with respect to the total amount of the cosmetic.
To 70% by weight, more preferably 20 to 60% by weight.
It is. This is because too much silicone oil may impair moldability, while too little silicone oil may impair the cosmetic effect.

(3) Anti-shininess cosmetic of the present invention The anti-shininess cosmetic of the present invention contains the above essential components and is used for the purpose of preventing shin. The anti-glare cosmetic of the present invention can be used as an under-makeup under a make-up or as an over-make-up on a make-up. In any use, and in the use of under-makeup and over-makeup therapies, it is possible to prevent the color rendering effect of make-up due to shine from being reduced. A particularly preferred use is for under makeup. In the anti-glare cosmetic of the present invention, a combination of translucent powder and silicone oil exhibits anti-glare action, but in a form suitable for use, that is, a solid or semi-solid form It is preferable to use an organic thickener to form an oil gel formulation in order to form the oil gel formulation. Such organic thickeners can be used without any particular limitation as long as they are commonly used in cosmetics. Examples of such organic thickeners include organically modified bentonites and dextrin fatty acid esters modified with quaternary ammonium salts and the like. Can be preferably exemplified. In a normal oil gel, an oil gel structure is formed with waxes such as carnauba wax and polyethylene, but in such a form, waxes as an essential component may increase shine and impair the effects of the present invention. It is preferable to use an oil gel dosage form using an organic thickener since it may not be able to exert its effect. Particularly preferred organic thickeners include
A preferred example of dextrin fatty acid ester, "Leopearl KL", which is a dextrin palmitic acid ester commercially available from Chiba Flour Milling Co., Ltd., is preferably exemplified. Needless to say, dextrin and an acid chloride derived from a fatty acid may be reacted in the presence of an alkali to synthesize and use. The preferred content of such an organic thickener is 1 to 20% by weight, more preferably 5 to 10% by weight, based on the total amount of the cosmetic. If the amount is too large, the gel becomes too hard and the usability may be impaired. If the amount is too small, the hardness may not be obtained and the stability may be impaired.

The anti-glare cosmetic composition of the present invention may contain any component usually used in cosmetics as long as the effects of the present invention are not impaired. Examples of such optional components include, for example, hydrocarbons such as squalane, petrolatum, and microcrystalline wax;
Esters such as jojoba oil, carnauba wax, octyldodecyl oleate, triglycerides such as olive oil, tallow, coconut oil, etc., fatty acids such as stearic acid, oleic acid and ritinoleic acid, oleyl alcohol, stearyl alcohol, octyldodecanol and the like Higher alcohols, anionic surfactants such as sulfosuccinates and sodium polyoxyethylene alkyl sulfate, amphoteric surfactants such as alkyl betaine salts, cationic surfactants such as dialkylammonium salts, sorbitan fatty acid esters, fatty acid monoglycerides, These polyoxyethylene adducts, polyoxyethylene alkyl ethers, nonionic surfactants such as polyoxyethylene fatty acid esters, polyethylene glycol, glycerin,
Polyhydric alcohols such as 1,3-butanediol, aqueous thickening / gelling agents, antioxidants, ultraviolet absorbers, coloring agents, preservatives, powder, hyaluronic acid and salts thereof, trehalose and analogs thereof , A chondroitin sulfate and a salt thereof, a heparin-like substance, a polymer having a sugar chain in a side chain, or a moisturizing active ingredient such as collagen. In selecting such an optional component, it should be noted that a substance that increases shininess or a substance that causes shininess is not selected, and from this viewpoint, other than silicone oil that tends to enhance shininess. It is very advantageous and preferable that the oil composition does not contain any oil or wax component, in other words, the oil composition is only silicone oil. Further, the content of the nonionic surfactant is also large, so that the content is preferably 1% by weight or less, and more preferably, the nonionic surfactant is not contained. By treating these essential components and optional components according to a conventional method, the cosmetic for anti-glare of the present invention can be produced.

EXAMPLES Hereinafter, the present invention will be described in more detail with reference to Examples, but it goes without saying that the present invention is not limited only to these Examples.

<Examples 1 to 3> Cosmetics for preventing shine according to the present invention were prepared according to the following formulation. That is,
The component (a) was pulverized with a pulverizer equipped with a 0.1 mm herringbone screen, added to the component (b) preheated to 80 ° C., stirred well, cooled with stirring, and homogenized by rolling over three rolls. Was obtained as a gel. As a comparative example, one in which silicone oil was replaced with many oils was produced. These cosmetics were used as under-makeup cosmetics for three panelists with remarkable shine, and make-up was made with a foundation having the following formulation, and three hours later, the appearance of shine was examined. The appearance of the shine was evaluated by a sensory evaluation (face 0: no shine, score 1: shine was slightly felt only in the T zone, score 2:
Clearness is clearly recognized in the T zone. Rating 3: Clearness is recognized in addition to the T zone. Rating 4: Evaluation based on the criteria that clearness is clearly observed on the entire face) and standard color plate (black, gray, white) ), The luminance was corrected by three standard color plates, the average luminance of the entire face image was calculated, and the average luminance of the face image immediately after the make was obtained as a rate of increase. As a control, the case where no under makeup was used was used. The results are shown in Table 1 as average values. From this, it can be seen that under makeup, which is the anti-glare cosmetic of the present invention, is excellent in anti-glare action.
It can also be seen that this can be achieved by the use of silicone oil and that the effect of the combination of volatile silicone and non-volatile silicone increases as a combination of silicone oil.
