Description

Description: TECHNICAL FIELD The present invention relates to a method for producing a multicolor powder solid cosmetic having various color tones of multiple colors, various shades, and different gloss in a single container. .

Here, the powder-based solid cosmetics are solid cosmetics such as eyeshadows, blushers, and solid white powders, which are made into powder by using a binder in a container or a medium plate, and are applied to the skin. Point to.

[Conventional technology]

In the conventional powder-type solid cosmetics, as a manufacturing method for obtaining a product having a plurality of color tones in a single container, a partition is provided in the container, and each room formed by this partition is colored individually. After filling different powders, the partition was removed and then pressed. However, this manufacturing method involves complicated steps, and the finished pattern is limited to a determined and unnatural color tone because the boundaries between the colors are clear depending on the partition shape. In addition, when a complicated pattern or a large number of colors is desired, the partition shape is complicated, and the difficulty of filling individual powders is increased. Was difficult to mass produce.

As a recent method for producing a solid cosmetic of a multicolored powder system, for example, in JP-A-60-38311 and JP-A-61-36206, powdery compositions having a granular or spherical shape having different tones are provided in the same container. A method of co-existing simultaneously with compression molding, and JP-A-60-67
No. 405, JP-A-60-67408, JP-A-60-172917, and JP-A-60-172918 disclose that two or more mud substances of different colors, which are a solvent and a powder cosmetic, are contained in the same container. There is proposed a method in which the solvent is absorbed from the back surface of the molding head while performing compression molding using a molding head or the like made of a porous material. However, the former method requires careful attention to the process so as not to damage the aggregated state, and the color tone is clearly divided to obtain only a monotonous pattern, while the latter method is compression molding. At the same time, the solvent must be sucked in using a porous absorber, etc., and since the absorber is also not suitable for continuous use, the endless sheet method etc. is adopted, and as the number of colors increases, so does the device. It becomes large-scale and the filling of mud tends to be complicated.

[Specific Description of the Invention]

The present invention has been proposed by the present inventors as a method for solidifying and molding powder in carrying out the method, as disclosed in JP-A-61-10000.
It is effective to use the powder solidifying device disclosed in JP-A No. 61-15812, JP-A No. 61-17507, and Japanese Patent Application No. 60-142317. That is, after injecting and filling the powder dispersion into a cylindrical container such as a pencil container or a porous body molding die held on the screen means, pressurizing air is applied from the upper surface of the powder dispersion or by a screen or the like. It is preferable to apply a method of applying pressure to remove the solvent in the powder dispersion through the screen means or the porous mold, molding, and drying.

The powder used in the present invention is a powder that has been conventionally used in makeup cosmetics, for example, an extender pigment, a white pigment, a coloring pigment, a pearl pigment, a metal soap, a starch, a ninelon powder, and the like. The surface of the powder is treated with a silicone (for example, methyl hydrogen polysiloxane), a metal soap, or an amino acid (for example, acylglutamate) by a conventionally known method as disclosed in JP-A-60-243006. A powder having water repellency can be used. These powders are appropriately mixed and used according to the type and application of makeup cosmetics.

The solvent used in the present invention may be a volatile solvent commonly used in cosmetics, and preferably does not sufficiently dissolve the powder and binder, that is, disperses the powder and binder. It is preferable that the powder can be held in the state and solidified or easily removed by evaporation. As a volatile solvent,
Examples thereof include ketones, alcohols, esters, and hydrocarbons, which can be used alone or in combination. More specifically, it is preferable to use the volatile fluorinated hydrocarbon solvent disclosed in JP-A-60-243006. In particular, the volatile fluorinated hydrocarbon solvent has a low boiling point, so it has good drying properties, can be sufficiently volatilized and removed even at room temperature, and has low toxicity, so it has little effect on workers and is nonflammable. Therefore, it has an advantage that it is highly safe from the viewpoint of fire protection.

As the binder used in the present invention, any binder can be used as long as it can be dispersed in a volatile solvent and can solidify the powder by its cohesive force after removing the solvent, and has been conventionally used for powder-based makeup cosmetics. Binder and
The organic bentonites disclosed in 60-243006 are used. In particular, when organic bentonite is used as a binder for powders, it swells without being dissolved in a solvent, forms a network structure and adsorbs the powder, and after removing the solvent, makes the powder a uniform shape. It plays the role of holding and maintains a good usability and adhesiveness as a solid cosmetic,
It has the effect of imparting the required strength, hardness, breakage resistance, etc. to the product. The binder is added to the powder dispersion in an amount usually used. More specifically, when organic bentonite is used, it is added in the range of 0.01 to 40% by weight based on the powder.

In addition to the above-mentioned powder, solvent and binder, the present invention, as a binding aid, solvent-insoluble microcrystalline cellulose increases the auxiliary action of the organic bentonite, that is, strength, and serves to maintain the shape. A polar substance such as propylene, ethanol, or acid is added in a small amount to promote the improvement of the binder effect, and thus can be added as necessary. Further, in order to prevent the product from changing with time, known additives such as preservatives, antioxidants, and ultraviolet absorbers, which are usually used in the field of powder solid cosmetics, can be added in appropriate amounts, if necessary.

The present invention constitutes the powder dispersion from the raw material composition described above, preferably further prepared a granulated product from the powder dispersion,
It is filled in a predetermined container or the like by the method described above. The amount of the solvent in the powder dispersion for filling is about 0.3 to 1 with respect to the powder composition.
The range of 0 times (weight ratio) is preferable. If it is less than 0.3 times, it becomes difficult to mix the granulated product and the powder dispersion liquid, and if it is more than 10 times, the granulated product is easily dispersed and mixed in the powder dispersion liquid. It becomes difficult to develop a multicolored color tone, and the loss of the solvent also increases.

Granulation from a molded product that expresses a clear color difference due to changes in the method of adding and mixing the powder dispersion and the granulated product, the time spent from addition to filling molding, and differences in molding conditions. A wide variety of multicolored powder type solid cosmetics are obtained, including molded products that can express a unique and fantasy color tone with a light and shade in which the color of the product and the color of the powder dispersion are subtly mixed. To be Furthermore, when using granules of a plurality of colors, a multicolor powder type solid cosmetic having a complicated pattern due to not only the difference in color but also the difference in individual addition amount, change in shape, difference in size, etc. can get.

The granulated product of the powder composition used in the present invention is most preferably obtained in the same manner as in the method of the present invention using the above-mentioned powder dispersion, in which case the aimed granulated product is a mold for molding. Alternatively, it may be obtained directly from the above, or may be obtained by crushing a large molded body. Alternatively, the powder may be obtained by direct press molding or another granulation method.
