Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cosmetic composition, and more specifically, a novel composition which is excellent in feeling in use, has a good feel after application, has sufficient strength and shape retention, and has good stability. It provides a variety of cosmetics.

[0002]

2. Description of the Related Art Cosmetics such as foundations and lipsticks are
It is mainly composed of various oils, surfactants, and powders, and in order to obtain a comfortable usability and a feeling of use as a cosmetic composition, a combination study of components having various shapes and properties has been conducted. In addition to these components, the blending of specific components has been investigated in order to form a stick-like shape or a solid powder-like shape as desired.

To improve the strength of stick-shaped cosmetics such as lipsticks, a large amount of high-melting wax is blended or an oil gelling agent such as sucrose fatty acid ester or organic modified clay mineral is added to solidify. Has been adopted so far. Further, in solid powder cosmetics such as powder foundation, a method of blending a paste-like viscous oil agent or a solid oil agent as a binder between powders has been used.

[0004]

However, although the above-mentioned conventional techniques improve the strength for maintaining the moldability, on the other hand, depending on the compounding amount and the combination with other components, there may be a problem in use and feel. was there. For example, if a large amount of high melting point wax is added to form a stick, the strength will be improved, but the elongation will be poor and the smoothness will be lost, and if solidified by adding a gelling agent, the liquid oil will become sticky and the feeling of use will increase. However, there are drawbacks such as deterioration of the oil and the liquid oil appearing on the surface over time. Further, if fumed silicic anhydride, which has a large oil absorption amount, or a plate-like powder is blended in order to eliminate this stickiness, the appearance is impaired, the system becomes brittle, and the strength is reduced, resulting in poor usability.

Further, in the case of a solid powder, although the molding strength upon standing is maintained to some extent by blending the above-mentioned oil agent, impact resistance during transportation and dropping is not sufficient, and if a large amount is blended, powder In some cases, the wetness of the product progressed and the feeling of use became heavy, or the system tightened over time and usability deteriorated. Therefore, it has been desired to develop a cosmetic having good strength and shape retention without impairing usability and usability.

[0006]

In view of the above circumstances, the present inventors have earnestly studied, and as a result, if a whisker-like calcium carbonate powder having a specific particle diameter was contained as an essential component,
It was found that an oil-based solidified cosmetic having good usability and usability, and having excellent strength and shape retention can be obtained,
The present invention has been completed. That is, the present invention has a minor axis: 0.
6~2.0μm, major axis: the particle size of the 5~40μm possess,
Whisker-like calcium carbonate powder having a specific surface area of 25.0 m ² / g or less, and solid fat and / or oil gelation
It is an oil-based solidified cosmetic characterized by containing an agent .
Hereinafter, the present invention will be described in detail.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The whisker-like calcium carbonate powder used in the present invention includes any production method including those produced by a conventionally known method. Minor diameter: 0.6-2 The particle diameter is 0.0 μm and the major axis is 5 to 40 μm. When the particle size is less than the above, sufficient strength and good shape retention cannot be obtained, and when calcium carbonate exceeding the above particle size is blended,
It is not preferable in terms of feeling in use, because it gives a feeling of roughness and fails to obtain good spread / spreading and smoothness. From the viewpoints of good usability and strength improvement, it is more preferable that the particles have the above-mentioned particle diameter and the bulk is a value measured by "K5101 pigment test method apparent specific volume (static method)" of JIS, It is 7.0-15.0 ml / g. Even within the range of the particle size and the bulk, when the specific surface area becomes large, that is, when the particle size becomes small, the cohesiveness of the powder tends to become strong, so that the specific surface area is 25.0
m ² / g not more than, good Mashiku is used as following 10.0 m ² / g. Examples of commercially available products having these characteristics include Whiskal A (manufactured by Maruo Calcium Co., Ltd.).

The content of the whisker-like calcium carbonate powder in the present invention is not particularly limited, but preferably,
1 to 45% by weight (hereinafter, simply referred to as "%") is blended. If used within this range, the effects of the present invention can be more exerted.

[0009] Oily solid cosmetic of the present invention, in addition to the above essential components, to blend the solid oil and / or oil gelling agent
It The solid oil agent is a so-called wax used in ordinary oily solid cosmetics, for example, candelilla wax, bead wax, carnauba wax,
Examples of the oil gelling agent include dextrin fatty acid ester, amino acid fatty acid ester, and 12-hydroxystearic acid. Oxy fatty acid esters such as and organic modified clay minerals.

In particular, among solid oil agents, the melting point is 80 to 1
The use of a wax at 05 ° C. is preferable because the stability at high temperature becomes better. Particularly preferred waxes include ceresin wax, paraffin wax, microcrystalline wax, Fischer-Tropsch wax, polyethylene wax, polyethylene polypropylene copolymer and the like.

The content of these solid oil agents is preferably 5 to 40%. Further, the content of the oil gelling agent is preferably 0.1 to 5%. When used in this range, a cosmetic having a good feeling of use and excellent shape retention can be obtained.

In addition to the above-mentioned essential components, the cosmetics of the present invention are used in other ordinary cosmetics, such as squalane, liquid paraffin, castor oil, liquid lanolin, silicone oil, and fluorine-based oil agents. Liquid oil, semi-solid oil such as petrolatum and lanolin, extender pigment, organic or inorganic color pigment, white pigment, pearl agent, powder component such as organic powder (these are metal soap, surfactant, silicone compound, It may be surface-treated with a fluorine compound, etc.), organic silicone resin, organic silicone gum, surfactant,
Polymer compounds, gelling agents, ultraviolet absorbers, antioxidants,
Preservatives, polyhydric alcohols, fragrances, beauty ingredients, salts, water and the like can be appropriately selected and used within a range that does not impair the effects of the present invention.

The oily solid cosmetic of the present invention can be used in any of skin care cosmetics, makeup cosmetics and hair cosmetics, but it is not limited to foundations, foundation cosmetics,
Eye shadow, cheek color, lipstick, lip balm,
Makeup cosmetics such as concealer is not preferred.
