Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a method for producing multicolor makeup cosmetics that allows makeup cosmetics of multiple colors to be filled into a single container with a good surface finish. [Prior Art] Generally, there are two types of makeup cosmetics: powder cosmetics and oil-based cosmetics.In the case of powder cosmetics, the method of filling the makeup cosmetics into a container is to A molding method in which compression molding is performed using a molding machine, and a pouring method in which powder cosmetics or oil-based cosmetics are made into a slurry and the slurry is poured into a container and solidified are known. When filling and molding powder cosmetics of multiple colors using the first molding method, for example,
As shown in Publication No. 44205, preliminary pressing is performed by filling powder cosmetics of each color into spaces within a container divided by partitions, and then main pressing is performed with the partitions removed. In addition, when filling and molding powder or oil-based cosmetics of multiple colors using the second pouring method, pour the slurry-form cosmetics of each color into each filling space in the container divided by partitions. , solidification is performed with the partitions removed. [Problems to be Solved by the Invention] The following problems exist with the above-mentioned prior art stamping methods. The first is that when the inside of a cosmetic container is defined into small filling spaces and each space is filled with powder cosmetics of different colors, the powder cosmetics tend to scatter. This is due to the fact that it gets mixed into the compartments and causes color mixing on the surface of the cosmetic. Second, when performing the main press on powder cosmetics molded by preliminary pressing, the partitions are removed from the container, but at this time the boundaries between the powder cosmetics of each color become misshapen, and colors are mixed on the surface. This is due to the formation of parts. Thirdly, when compressing powder cosmetics, the basis weight is applied with a release paper interposed between the press and the cosmetics in order to prevent impression marks from forming. The disadvantage is that it is discarded after each drying operation, which increases manufacturing costs. On the other hand, the pouring method of the prior art has the following drawbacks. The first problem is that when an oil-based cosmetic is slurried and poured into a container, traces of pouring appear on the surface of the solidified cosmetic as uneven color. Second
For example, in the case of an oil-based cosmetic A containing a scaly powder such as a pearl agent, in order to prevent the scaly powder from settling, the base material of the oil-based cosmetic A is lower than that of a solid oil-based cosmetic base B that does not contain a scaly powder. It is necessary to reduce the mixing amount or to cool rapidly. However, when solid oily cosmetic base A containing scaly powder and solid oily cosmetic base B not containing scaly powder are poured into a single small container, each of the cosmetic bases A, B Solid oily cosmetic base A differs in solidification speed.
There is a problem that the surface of (B) is solidified while remaining uneven, resulting in unevenness and uneven coloring. Furthermore, when makeup cosmetics of multiple colors are filled in a single container, the cosmetics of each color are mixed to form an intermediate color upon use, but none of the methods of the prior art It has been difficult to fill in advance a neutral color that changes continuously between different color make-up cosmetics. The present invention was developed in view of the above-mentioned drawbacks of the prior art, and it is possible to mold the surface of makeup cosmetics of multiple colors filled into a container into a beautiful finish without color unevenness or unevenness, and furthermore, the surface can be formed continuously if desired. To provide a method for producing a multicolor make-up cosmetic that can be molded into a state in which the color has changed, thereby allowing a user to check in advance the intermediate blended color of each color of the make-up cosmetic. [Means for Solving the Problems] The means adopted by the present invention to solve the above-mentioned problems is to fill makeup bases of multiple colors in parallel in a container, and to create makeup cosmetics of multiple colors. A slurry of multiple colors obtained by slurrying the base is sprayed onto the upper surface of the multicolored makeup cosmetic base filled in the container in a manner corresponding to the color scheme of each makeup cosmetic base. That's what I did. [Detailed Description of the Invention] Make-up cosmetic bases containing pigments of various colors used in the present invention include powder cosmetic base C and oil-based cosmetic base D. Each of the bases C and D will be explained below. The powder cosmetic base C consists of extender pigments, organic pigments, inorganic pigments, metal soaps, pearlescent agents, oily substances, and the like. The powder cosmetic base C is filled into a container by a conventional molding method or a pouring method, but when using the pouring method, the powder cosmetic base C is filled with a volatile solvent. Forms into a slurry. More preferably, a fixing agent may be added. The fixing agent includes organic bentonite, which functions as a binder for the powder and improves the impact resistance and breakage resistance of the solidified powder cosmetic. . Examples of the organic bentonite include stearyldimethylbenzylammonium hectorite, dimethyldihydrogenetated tallow ammonium hectorite (trade name "Bentone 38", manufactured by National Lead Company, USA), and the like. Moreover, ethyl cellulose can be used in combination with or selectively with organic bentonite. When organic bentonite and ethyl cellulose are used together, the appropriate blending ratio is in the range of 20:1 to 1:1. The blending ratio of the organic bentonite and/or ethyl cellulose mentioned above and the powder is 1.0:99.0
A range of ~20.0:80.0 is suitable in terms of adhesion and impact resistance. Further, the volatile solvent has a boiling point of 200°C or less, but preferably one with a boiling point of about 30 to 100°C that can be volatilized at room temperature. Volatile solvents include trichlorotrifluoroethane (“Fronsiowa 113” manufactured by Showa Denko K.K.), ethanol, acetone, and low-boiling hydrocarbons (Humble Oil & Co., Ltd., USA).
There are products such as ``Isopar A'' manufactured by Refining Company. The appropriate amount of the volatile solvent to be used is 0.5 to 10 times (by weight), preferably 3 to 7 times, the total amount of the powder and the fixing agent. Furthermore, in addition to the above-mentioned powder, fixing agent, and volatile solvent, preferably 1.0 to 20.0% by weight of crystalline cellulose, organic bentonite, and swelling of ethyl cellulose to the volatile solvent are added to improve the "removal" of the powder. Propylene carbonate as accelerator from 0.5 to
5.0% by weight of each may be added and mixed instead of powder. On the other hand, oil-based cosmetic base D is liquid paraffin,
It consists of liquid oils such as synthetic ester oils and olive oil, solid raw materials such as solid paraffin, wood wax, beeswax, and carnauba wax, and pigments used in the production of make-up cosmetics and fragrances used in the production of solid perfumes. . As the volatile solvent for slurrying the oil-based cosmetic base D, the volatile solvent used for melting the powder cosmetic base described above is used. The amount of volatile solvent used varies depending on the components of the oil-based cosmetic base D, and also differs depending on whether it is poured into a container or when it is sprayed, as will be described later. In the present invention, the oil-based cosmetic base D may be melted using a heating means instead of the above-mentioned volatile solvent to form a slurry. The heating melting temperature in this case is 70 to 100°C, which is higher than the melting point. The molding process according to the present invention is as follows.
