Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a multicolor powder cosmetic composition capable of being filled with powder cosmetics of a plurality of colors in a container so as to continuously change colors. It relates to a manufacturing method.

[Conventional technology]

Conventionally, for example, eye shadow, lipstick, foundation,
As a method for filling a single container with a plurality of types of powder cosmetics having oiliness such as blusher and having different colors, for example, JP-A-59-44205, JP-A-61-1610, etc. Those shown in are known. That is, in the former method, powder cosmetics are filled in each space in the container 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, each of the above-mentioned conventional methods is one in which powder cosmetics are filled in the powder state as they are, and then the preliminary press and the main press are performed to form a mold. There was a problem.

First, although the container for the usual cosmetics is small, it is not only inferior in workability to divide the container into a plurality of small area compartments and directly fill the compartments with the powder cosmetics. However, since it is a powder, there is a problem that it is likely to be 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 easily 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 above-mentioned drawbacks of the prior art, and as a result of being able to fill powder cosmetics of multiple colors in a container without performing a pressing step, it is possible to simplify the manufacturing process and improve manufacturing efficiency, Moreover, it is an object of the present invention to provide a method for producing a multicolor powder cosmetic in which the multicolor powder cosmetic can be continuously filled in the container in a state where the color changes.

[Means for solving problems]

In order to solve the problems described above, the means adopted by 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 a plurality of colors,
The slurry-like substances of the respective colors are arranged next to each other in the container so as to partially overlap each other, and simultaneously sprayed and then dried.

[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.

Examples of the fixing agent used in the present invention include organic bentonite. The organic bentonite has a function as a binder for the powder, and improves the impact resistance and breakage resistance of the powder cosmetic solidified into a thin film. 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.
