etc. are known.

[Problem to be solved by the invention]

However, in all of these marble-consolidated powder makeup cosmetics obtained by these conventional manufacturing methods, the color inside the cosmetic is the same as that on the surface, so it is always the same as before use. The appearance was monotonous.

Therefore, an object of the present invention is to provide a method for producing a solid powder makeup cosmetic that has a marble tone with a more complicated color scheme and that can enjoy changes in pattern and color as it is used.

[Means to solve the problem]

In order to achieve this object, the present inventors have conducted intensive research and have completed the present invention.

That is, the present invention is a method for producing a multicolor powder solid cosmetic, which is characterized in that multicolor cosmetic granules are placed in a cosmetic container and then compression molded.

The multicolored cosmetic granules used in the present invention are cosmetic granules having a plurality of color layers from the inner center to the outer surface, in other words, a plurality of color layers concentrically arranged in a cross section. Such multicolored cosmetic granules can be obtained by appropriately granulating powder bases of multiple colors so that adjacent layers have different colors.

Tar pigments such as No. 1, Green No. 204, Blue No. 201, and Green No. 205; carminic acid, laccaic acid, calsamine,
Lakes made from natural pigments such as brushlin and crocin,
and those obtained by treating the above-mentioned powder base with a silicone oil or the like to make it lipophilic. These can be used alone or in combination of two or more.

When granulating the powder base, oil agents, water-soluble polymers, oil-soluble polymers, binders, etc. commonly used in cosmetics can be blended as binders.

Examples of oil agents include hydrocarbons such as squalane, petrolatum, liquid paraffin, microcrystalline wax, and ceresin; higher fatty acids such as stearic acid, oleic acid, isostearic acid, palmitic acid, and myristic acid;
Higher alcohols such as cetyl alcohol, oleyl alcohol, stearyl alcohol; Esters such as isopropyl palmitate, isopropyl myristate, 2-octyldodecyl myristate, isostearyl isostearate; monostearic acid glyceride, 2-ethylhexanoic acid Glycerides such as triglyceride and coconut oil fatty acid triglyceride; Silicones such as dimethylpolysiloxane and methylphenylpolysiloxane; Lanolin such as lanolin, hydrogenated lanolin, white lanolin, and liquid lanolin; Waxes such as beeswax and gay wax; mink oil , animal oils such as sea turtle oil; vegetable oils such as olive oil, etc., and it is preferable to blend them in an amount of 0.1 to 40% by weight, particularly 0.5 to 25% by weight, based on the powder base. Incidentally, the oily agent may be used as an oily component for a purpose other than that of the binder.

Examples of water-soluble polymers include gelatin, casein, starch, gum arabic, guar gum, locust bean gum, gum tragacanth, starch derivatives, cellulose derivatives, polyvinyl alcohol, polyvinylpyrrolidone, etc. ~5% by weight,
In particular, it is preferably blended in an amount of 0.1 to 3% by weight.

Examples of oil-soluble polymers include ethyl cellulose, acetyl cellulose, nitrocellulose, vinyl acetate resin, acrylic resin, etc.
It is preferable to blend it in an amount of 0.1 to 3% by weight, particularly 0.1 to 3% by weight.

Note that these oil-soluble polymers may be used as a polymer emulsion.

As a binder, sodium magnesium silicate,
Magnesium aluminum silicate, fine particulate silicic anhydride, hydrophobized fine particulate silicic anhydride, etc. are included, and are blended as necessary.

In the present invention, one type or a combination of two or more types selected from the above-mentioned oil agent, water-soluble polymer, oil-soluble polymer, and binder can be used as the binder.

In addition, depending on the target product to be manufactured, oil-based ingredients, preservatives, medicinal ingredients, fragrances, surfactants, antioxidants, chelating agents,
Ultraviolet absorbers and the like can be added as necessary.

Examples of granulation methods for the powder base include known granulation methods such as fluidized bed granulation, centrifugal granulation, and agitation granulation; examples include names such as super mixer, Henschel mixer, and speed kneader. It is carried out by using a granulator called . Moreover, in addition to the above-mentioned binder, a solvent such as water or ethanol can be added during granulation.

For example, granulation is carried out by placing a powder base in a granulator and adding a binder while rotating it. Here, other components such as oily components may be added and mixed with the powder base in advance, or may be added together with the binder or added in a state dissolved or dispersed in the binder.

In this way, the core (the innermost layer of the granule) is first granulated [the first
Figure (1)], then a second layer is formed by gradually adding a powder base and a binder of a different color from that used for core granulation while stirring in the granulator [Figure 1 (2)]. )] is formed. Thereafter, by repeating this process, multicolored granules having a desired number of layers can be obtained. Note that the number of layers of multicolored granules can be any number, but from the viewpoint of use in cosmetics, it is preferably about 2 to 5 layers. Further, the diameter of the core is preferably in the range of 0.5 to 10 mm, the particle size of the multicolored granules is preferably in the range of 1 mm to 50 mm, and the shape is preferably spherical or approximately spherical.

The thus obtained multi-colored granules are placed in a cosmetic container such as a medium plate or a compact body (Fig. 1 (3)) and compression molded (Fig. 1 (4)). ].

Here, in order to facilitate compression molding, 10 to 60% by weight of a solvent such as water or ethanol may be added to the multicolored granules before compression molding. In this case, after molding, it is necessary to dry at room temperature to high temperature. When compression molding is performed using two or more multi-colored granules, the outermost layer may have the same color [Article 21ffl (1)] or different colors [Fig. 3 (1)]; , different sizes may be used. Further, multicolored granules and single granules may be used in combination.

The thus obtained multicolored powder solid cosmetic has the appearance of a monochrome solid cosmetic when multicolored granules with the same color on the outermost layer are compression molded, and multicolored granules with different colors on the outermost layer are compression molded. In this case, the appearance is simply that of a marble-containing cosmetic, but in either case, various colors appear inside as it is used, forming a complex pattern, and you can enjoy the changes.

Furthermore, by cutting the surface of the solid cosmetic after compression molding, it is possible to make the appearance more complex and beautiful before use [Figure 1 (5), Figure 2 (2), Figure 3 Figure (2
)].
