Description

TECHNICAL FIELD The present invention relates to a method for producing a thin film-like multicolor powder cosmetic, which is suitable for use in a small amount and whose color continuously changes.

[Prior art]

Conventionally, for example, lipstick, eye shadow, foundation,
In order to use multicolored powder cosmetics with oiliness such as blusher for small use such as trial use, portable use or disposable use, small-sized cosmetic containers are filled with powdered cosmetics of each color and solidified. The way to do is done.

In this way, a single container is filled with powder cosmetics of multiple colors,
As a method of solidifying, for example, those disclosed in JP-A-59-44205 and JP-A-61-1610 are known. That is, in the former method, powder cosmetics are filled in each of the spaces partitioned by the partition to perform preliminary pressing, and then the main pressing is performed with the partition removed. On the other hand, in the latter method, the powder cosmetic is filled in the space formed by one of the mold pieces and prepressed by the other mold piece, and then by the other mold piece. The space formed is filled with powder cosmetics, pre-pressed with one die, and then the main press is performed using an adjusted die.

[Problems to be Solved by the Invention] However, in the above-mentioned respective prior arts, when the powder cosmetic is filled, the powder is filled in the powder state, and then the preliminary press and the die press by the main press are performed to form However, there are the following problems.

Firstly, although the cosmetic container which is usually used in a small amount is small, it is inferior in workability to divide the container into a plurality of small area compartments and directly fill the compartment with the powdered cosmetic composition. In addition, since it is a powder, there is a problem that it is easily scattered around due to a slight change in movement, etc., and it mixes with other compartments to cause color mixing.

Secondly, a powder molded product is first made by preliminary pressing, and this powder molded product is transferred to another female mold, or the main pressing is carried out by using another male mold or shaping die. There is a problem that the manufacturing process becomes very complicated because of the large number of processes and the need for various types of press dies.

Thirdly, in a small container, a sufficient compression force cannot be applied at the time of punching, so that the powder cosmetic material is cracked by vibration during transportation, Because you need a certain amount of powder cosmetics,
It is necessary to mold an unnecessary amount for a small amount of use,
There is a problem of waste.

The present invention has been made in view of the problems of the method for producing a multicolor powder cosmetic by the above-mentioned die-casting method.By spraying a slurry-like material of each color on a mount, a multicolor powder including an intermediate color is obtained. It is an object of the present invention to provide a method for producing a thin film multicolor powder cosmetic, which can fix the body cosmetic on the mount and can be suitably used for a small amount of use.

[Means for solving problems]

In order to solve the above problems, means adopted by the method of the present invention is a powder containing pigments of different colors, a fixing agent, and a volatile solvent are mixed to form a slurry of multiple colors,
The slurry-like materials of the respective colors are next to each other so as to partially overlap each other on the mount, and sprayed in a thin film at the same time, and then dried so that the color of the thin film multicolored powder continuously changes on the mount. It is to fix the body cosmetics.

[Specific Description of the Invention]

Powders containing pigments of each color used in the present invention include extender pigments, organic pigments, inorganic pigments, metallic soaps, pearlescent agents, and mica, which have been conventionally used as materials for makeup cosmetics.

The adhesive used in the present invention includes, for example, organic bentonite, which has a function as a binder for the powder, and has impact resistance and breakage resistance of the powder cosmetic solidified into a thin film. It improves the sex. Examples of the organic bentonite include stearyl dimethyl benzyl ammonium hectorite, dimethyl dihydrogenated tallow ammonium hectorite (trade name "Benton 38" manufactured by National Lead Co., USA), and the like.

In addition, ethyl cellulose can be used in combination with or selectively with organic bentonite. When using organic bentonite and ethyl cellulose together, the compounding ratio is 20: 1 ~
A range of 1: 1 is suitable.

The compounding ratio of the aforementioned organic bentonite and / or ethyl cellulose to the above powder is preferably in the range of 1.0: 99.0 to 20.0: 80.0 in terms of adhesion and impact resistance.

The volatile solvent used in the present invention has a boiling point of 200 ° C. or less, and preferably has a boiling point of about 30 to 100 ° C., which can be vaporized at room temperature. As a volatile solvent, trichlorotrifluoroethane (“Front Shower 11 manufactured by Showa Denko KK”
3 ”), ethanol, acetone, low boiling hydrocarbons (“ Isoper A ”manufactured by Humble Oil and Refining Company, USA), etc. The amount of the volatile solvent used is appropriately 3 to 10 times (weight ratio), preferably 5 to 7 times, the total amount of the powder and the adhesive.

In the present invention, the powder of each color, the fixing agent, and the volatile solvent described above are essential components, but preferably 1.0 to 20.0% by weight of crystalline cellulose and volatile in order to improve the “melting” of the powder. 0.5 to 5.0% by weight of propylene carbonate as a swelling promoter for organic bentonite and ethyl cellulose against solvents
Each may be added and mixed in place of the powder.

Further, as the mount used in the present invention, a synthetic resin sheet is used in addition to pulp paper. The hardness of the mount is not particularly limited, and the mount may be as soft as sulfuric acid paper.

The molding process according to the present invention is as follows.

Powders of colors A, B, and C are respectively put into the mixer tanks of each color, a volatile solvent is added to the powders of each color, and mixed and stirred by each mixer [, ′, ″].
A volatile solvent is added to the organic bentonite and / or ethyl cellulose, and the mixture is similarly mixed and stirred by a mixer [, ′, ″].
