Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for producing multicolor makeup cosmetics that can be molded into a multi-ring shape such as an annual ring pattern.

[Conventional technology]

In general, there are two types of makeup cosmetics: powder cosmetics and oil-based cosmetics.In the case of powder cosmetics, the makeup cosmetics are filled into a container and then put into a mold using a molding machine. A molding method in which compression molding is used, 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, Japanese Patent Laid-Open No. 59-442
As shown in Publication No. 05, 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-formed cosmetics of each color into each filling space in a container divided by partitions, and remove the partitions. It solidifies in the removed state.

[Problem that the invention seeks to solve]

In any of the conventional methods described above, makeup cosmetic bases of multiple colors can be arranged horizontally in a container by molding. It has not been possible to produce a novel multicolored makeup cosmetic in which molded layers are laminated concentrically in the radial direction and molded into a multi-ring shape.The present invention was created in view of the drawbacks of the prior art described above. To provide a method for producing a multicolor makeup cosmetic that can be molded into a multi-ring shape in which molded layers of each color appear concentrically and has a novel shape different from a conventional planar shape.

[Means for solving problems]

The means of the present invention configured to solve the two problems is to form a slurry of makeup cosmetic bases of multiple colors using a volatile solvent or heating means, and to form the slurry of each color into a slurry. It consists of sequentially repeating the steps of depositing the material in a thin film form on the outer surface of a rod-shaped core material rotating at a predetermined speed and solidifying it.

[Detailed description of the invention]

Make-up cosmetic bases containing pigments of various colors used in the present invention include powder cosmetic base A and oil-based cosmetic base B. Each of the bases A and B will be explained below.

Powder cosmetic base A consists of extender pigments, organic pigments, inorganic pigments, full-strength soaps, pearlescent agents, oily substances, and the like. The powder cosmetic base A is filled into a container by a conventional molding method or a pouring method, but when using the pouring method, the powder cosmetic base A is mixed into a slurry using a volatile solvent. Generate into things. More preferably, a fixing agent may be added, and the fixing agent includes organic bentonite, and the organic bentonite has a function as a binder for the powder, and the powder is solidified in a thin film. It improves the impact resistance and breakage resistance of cosmetics. Examples of the organic bentonite include stearyldimethylbenzylammonium hectorite, dimethyldihydrogenated 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 using organic bentonite and ethyl cellulose together, the blending ratio is 20:
A range of 1 to 1:1 is suitable.

The mixing ratio of the above-mentioned organic bentonite and/or ethyl cellulose and the powder is 1.0:99.0-20.
A range of 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. In addition, volatile solvents containing water may be used. Examples of volatile solvents include trichlorotrifluoroethane ("Fronshowa 113J" manufactured by Showa Denko K.K.), ethanol,
Acetone, a low boiling point hydrocarbon ("Isopar AJ" manufactured by Hemble Oil and Refining Company, USA), etc. are preferred.The amount of volatile solvent used is 0.5 to 10 times the total amount of powder and fixing agent. (weight ratio), preferably in the range of 3 to 7 times.

Furthermore, in addition to the above-mentioned powder, fixing agent, and volatile solvent, preferably 1.0 to 20.0% by weight of crystalline cellulose and an organic compound with respect to the volatile solvent are added in order to improve the "lodgeability" of the powder. Propylene carbonate is used as a swelling accelerator for bentonite and ethyl cellulose at a concentration of 0.5 to 5. OgL amount % may be added and mixed instead of powder.

On the other hand, oil-based cosmetic base B includes liquid paraffin, synthetic ester oil, liquid oil such as olive oil, solid paraffin, solid raw materials such as wood wax, beeswax, and carnauba wax, and pigments for producing makeup cosmetics. It consists of

The volatile solvent used to form the oil-based cosmetic base B into a slurry is the volatile solvent used to melt the powder cosmetic base described above. The amount of volatile solvent used varies depending on the components of oily cosmetic base B.

The bases can be made into a slurry using a known method, namely, if it is a powder cosmetic base, it is melted using a volatile solvent [■], whereas if it is an oil-based cosmetic base, it is melted using a volatile solvent or by heating. A method of melting by means [either (1) or (2) can be used.

Next, a zero-color slurry is applied to the outer surface of the rod-shaped core material rotating at a predetermined speed by flowing it down in the form of a thin film through, for example, a slit. When a volatile solvent is used, it can be vaporized naturally or by forced vaporization such as hot air or lamp irradiation.
In addition, when a heating means is used, the zero color slurry is solidified by blowing cooling air [e], and a C color makeup consisting of a thin film layer with a desired thickness of, for example, about 0.5 to 5 cm is formed. A make-up cosmetic layer is formed on the outer surface of the core material. After that, the 0-color slurry is deposited on the upper surface of the C-color makeup cosmetic layer in the form of a thin film and solidified (6))

As described above, makeup cosmetic layers of 0 color, D color, and E color are formed in a multilayered manner on the outer surface of the rod-shaped core material, and if necessary, this thin film is applied while flowing down, and solidified. After repeating the process of forming a cylindrical material, a multi-ring-shaped multicolored makeup cosmetic can be produced by removing the rod-shaped core material.

In addition, in the molding process, a multi-ring-shaped multicolored makeup cosmetic is molded on the outer surface side of a rod-shaped core material using makeup cosmetic bases of three colors, color 0, color D, and color E. ,
The present invention is not limited to make-up cosmetics of three colors, but can mold make-up cosmetics of two or four or more colors into a multi-ring shape. Also, 0 color, D color, E
The order in which the makeup cosmetics of each color are stacked can be selected as desired.

Furthermore, by appropriately selecting the rotational speed of the rod-shaped core material, the number of rotations in each step, the concentration of the slurry, and the film pressure when flowing down, each color makeup #I layer can be formed to the desired thickness. be able to.
