Description

TECHNICAL FIELD The present invention relates to a thin film powder solid cosmetic suitable for use in a small amount.

[Conventional technology]

Conventionally, powder cosmetics such as eye shadows, foundations, and blushers are known to be fixed in a thin film on a mount in order to be used for trial use, small amount use such as portable or disposable. The applicant of the present application filed Japanese Patent Application Laid-Open No. 63-
The manufacturing method was proposed by Japanese Patent No. 139109. This thin film powder solid cosmetic preparation method comprises mixing powder, organic bentonite and / or ethyl cellulose, and a volatile solvent to form a slurry, and spraying the slurry on a mount in a thin film. After that, by drying, the thin film powder cosmetic is fixed on the mount, the time of the drying process can be shortened, and uneven coloring and uneven drying can be prevented. It has excellent advantages such as the ability to form a very small amount of powder cosmetics in the form of a thin film.

[Problems to be Solved by the Invention]

By the way, in the above-mentioned conventional technique, since so-called CFC gas such as trichlorotrifluoroethane is used as a volatile solvent for forming a powdery substance, an organic bentonite or the like into a sprayable slurry, the conventional technique is used. When, for example, a sample is manufactured by the above method, there are the following unsolved problems.

That is, for a powder solid cosmetic material to be accommodated in a compact case as an actual product, a powder cosmetic composition such as powder and binder is filled in a gold plate and compression-molded using a molding machine. As a result, it is solidified, and the oily component of the binder is in a state of enclosing the powder.

On the other hand, in the prior art in which the powder cosmetic composition is made into a slurry and sprayed, a solvent such as CFC gas is used, and therefore the oily component of the binder is in a state of permeating the powder.

Thus, the powder solid cosmetic product actually used by the customer and the sample according to the prior art differ in the dispersion state of the oily component, and as a result, the quality and feel of the sample differ from the actual product. The problem is that

In addition, since the conventional technique uses the spraying means, in order to form a pattern on the surface of the thin film powder solid cosmetic, a press for pattern formation must be performed, which increases the number of steps. There is a drawback that.

Furthermore, since the thin film powder solid cosmetic according to the prior art is simply attached to the mount, and the adhesive force to the mount is weak, the thin powder solid cosmetic with the mount has a desired size, There is a defect that a part of the cosmetic material is cut off when it is cut into a shape, and the cosmetic material is easily peeled off from the mount.

Furthermore, from the viewpoint of environmental protection, the use of CFCs is gradually regulated, and when CFCs and the like are used as a solvent, the conventional technique is required to cope with the situation.

The present invention has been made in view of the above-mentioned unsolved problems and drawbacks of the related art, and is lacking because the usability can be the same as that of an actual product and the adhesiveness to the mount is excellent. The present invention provides a thin film powder solid cosmetic having excellent durability without peeling or peeling.

[Means for Solving the Problems]

Means of the present invention, which is configured to solve the above-mentioned problems, is a backing sheet, and a top surface side is a cosmetic material holding section having innumerable minute recessed portions, and a bottom surface side is a sticking section to be stuck to the backing sheet. And a powdery cosmetic composition which is compression-molded into a thin film solid form on the cosmetic material holding portion side of the cosmetic material holding sheet.

[Action]

The powder-to-cosmetic composition solidified by compression-molding in the cosmetic-retaining portion of the cosmetic-retaining sheet having the above-described configuration has the lower side filled in the innumerable minute concave and convex portions. The thin film powder solid cosmetic is securely retained without peeling.
