Description

  The present invention relates to a powder cosmetic. More specifically, the present invention relates to a powdery cosmetic containing oil.

  Powder cosmetics are generally used as finishing cosmetics, and are widely used for the purpose of producing a transparent skin quality, suppressing sweat and sebum, and improving makeup retention. Since the powder cosmetic is in the form of a powder, it has a soft and soft usability when taken. However, since the main component is powder, the finish is powdery, and there is a drawback that a moisturizing feeling cannot be obtained. These drawbacks are remarkable in use in a low humidity season such as winter, and are particularly fatal for people with dry skin.

  On the other hand, various powder cosmetics containing a moisturizing oil in the powder have been developed. For example, a powdery cosmetic containing porous dextrin and an oil (see Patent Document 1), a powdered cosmetic containing a fluorinated powder and a specific oil component (see Patent Document 2), an ester with octenyl succinic anhydride A powdery cosmetic for cleansing cosmetics (see Patent Document 3) and the like, which is composed of modified starches such as chemicals and make-up-removed oil, are disclosed.

  However, conventional powder cosmetics have some deficiencies, such as insufficient moisturizing feeling, many cosmetics that are unsatisfactory in usability and usability, and unstable powder state. . For example, the powder cosmetic containing the fluorinated powder of Patent Document 2 employs a technique of coating the surface of the oil with powder to make it powder, so the stability of the system is poor due to weak adsorption For example, when the container is filled, an external force is applied, so that there is a drawback that the adsorption is easily broken. Accordingly, the present situation is that it is desired to develop a powder cosmetic material that does not impair the usability and the feeling of use, and that stably contains an oil and imparts a sufficient moisturizing feeling.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a powder cosmetic that has excellent moisturizing feeling, good feeling of use, and stability while maintaining the usability as a powder cosmetic. .

  As a result of diligent research to solve the above problems, the present inventor has found that the above problems can be solved by blending oil with a petal-like powder having a specific particle size to prepare a powder cosmetic. The present invention has been completed.

  That is, the first invention is a powder cosmetic containing a petal-like powder having an average particle diameter of 1.0 to 30.0 μm and an oil content of 5 to 75% by mass in the total amount of the powder cosmetic, wherein the oil content and the petal shape It is the said powder cosmetics whose mass ratio (oil content / petal-like powder (mass ratio)) of powder is 0.4-5.5.

  The second invention is the powder cosmetic according to the first invention, wherein the petal-like powder is petal-like calcium silicate.

  In the present invention, the powder cosmetic is a powder cosmetic whose appearance is in the form of a powder. Moreover, the display of the average particle diameter in this invention is measured by SEM. In the present invention, liquid, semi-solid, solid, solid and the like represent a state at normal temperature unless otherwise specified.

  According to the present invention, a petal-like powder with an average particle size of 1.0 to 30.0 μm and a powdery cosmetic powder containing 5 to 75% by mass of oil are mixed, and the mass ratio of oil to petal-like powder (oil content) / Petal powder (mass ratio) was adjusted to 0.4 to 5.5, and the powder cosmetic was prepared, and while maintaining the usability as a powder cosmetic, it had excellent moisturizing feeling, usability and stability. A good powder cosmetic is obtained.

  Hereinafter, the best mode for carrying out the present invention will be described in detail.

  In the present invention, petal-like powder is used. The petal-like powder is a porous powder having a petal-like crystal structure in which petal-like flake powder is grown in multiple directions to form an aggregate.

  The powder in the petal-like powder is not particularly limited as long as it is a powder that can form a petal-like aggregate, but calcium silicate, calcium phosphate, magnesium silicate, magnesium phosphate, magnesium carbonate, etc. are preferable, especially Calcium silicate is preferable, and the effects of the present invention are remarkably exhibited, such as containing oil stably.

  The petal-like calcium silicate powder preferably used in the present invention is a gyro represented by the general formula 2CaO · 3SiO 2 · nSiO 2 · mH 2 O (where m and n are positive numbers and n is 0.1 to 10). It belongs to light type calcium silicate.

  The petal-like powder is a known substance, and is produced by a known method, for example, a method described in JP 54-93698 A, JP 9-25108 A, JP 2003-26196 A, or the like. Can do. For example, in the case of petal-like calcium silicate, a sodium silicate aqueous solution and a calcium chloride aqueous solution are mixed at room temperature, and the resulting suspension is heated in an autoclave and reacted at a temperature of, for example, 180 ° C. To produce petal-like calcium silicate. The resulting product is produced by washing and drying with ion-exchanged water and ethanol.

  The petal-like powder in the present invention has a high oil absorption capacity due to a special petal-like structure. The oil absorption capacity is preferably one having an oil absorption of 1.5 ml / g or more from the viewpoint of sufficiently exerting the effects of the present invention. Thereby, even in the presence of oil, the powdery state can be sufficiently maintained, and the powder cosmetic can be stably powdered. More preferably, it is 2.0 ml / g or more. The upper limit of the oil absorption is not particularly limited, but 6.0 ml / g is sufficient from the viewpoint of maintaining the powder form and sufficiently exhibiting a moisturizing feeling. In the present invention, it is particularly preferably 1.5 to 6.0 ml / g. More preferably, it is 2.0-5.0 ml / g. The oil absorption amount can be measured by a method using linseed oil in JIS pigment test method K5101, which is a conventional method, and the oil absorption amount in the present invention is a value determined by this method.

  The petal-like powder having an average particle size of 1.0 to 30.0 μm is used. By using a powder having a mean particle size (hereinafter simply referred to as “particle size” is also an average particle size) within this range, a powdery dry feeling of powder cosmetics can be obtained, and cosmetics can be used. It is possible to obtain an excellent effect with no smearing due to the feeling of use such as smoothness and elongation of the cosmetic application. When the particle diameter is less than 1.0 μm, a feeling of good elongation cannot be obtained particularly when a powder cosmetic is applied. On the other hand, if it exceeds 30.0 μm, a smooth feeling of use when a powder cosmetic is applied cannot be obtained. In either case, the dry feeling of the powder cosmetic is also reduced. A preferable particle diameter is 2.0 to 20.0 μm. In order for the petal-like powder to be aggregated to have a particle size of 1.0 to 30.0 μm, the longitudinal direction is 0.1 to 30 μm and the thickness is 0.001 to 0.1 μm. preferable. A more preferable particle size is 4.0 to 20 μm.

  In the use of the petal-like powder, when the powder is pulverized and the particle diameter is adjusted, a pulverizer is generally used, and the petal-like powder is used as long as the petal shape is not impaired. As the pulverizer, for example, a compression pulverizer, a shear pulverizer, an impact pulverizer, a ball medium pulverizer, an airflow pulverizer, or the like can be used. The classification includes a natural sedimentation method and a cyclone method, but is not particularly limited.

  As the petal-like powder in the present invention, a commercially available product can be used. In use, the commercially available product is used as it is or after being pulverized and classified. Examples of commercially available products include, for example, Florite R (petal calcium silicate, particle size 25 μm) (manufactured by Tokuyama Corporation), Polonex C (petal calcium carbonate / calcium phosphate complex, particle size 10 μm) (Maruo Calcium Co., Ltd.) Company-made). The chemical formula of the above fluorite R is 2CaO · 3SiO 2 · nSiO 2 · mH 2 O (where m and n are 2 <m <3 and 1 <n <2), and the crystal system is a modified gyrolite. . The particle size (D50) is 20 to 30 μm, and the pore radius has a peak in the vicinity of 0.1 μm.

  In the present invention, by using a petal-like powder having an average particle size of 1.0 to 30.0 μm, it is possible to obtain a powdery cosmetic powder with a dry feeling even if a large amount of oil is blended. This powder cosmetic is stable and provides a sufficient moisturizing feeling. Furthermore, it has an excellent feeling of use such as smoothness and elongation of the cosmetic application when using the cosmetic.
