(10) Preparation Example 1: Manufacture of Mesh Net-Type Cushion Cosmetic Product

(11) The cosmetic compositions prepared according to the Examples and the Comparative Examples were in the form of solid balm formulations and thus were loaded in a high temperature state of 70-80 C. into mesh net-mounted cosmetic containers to manufacture mesh net-type cushion cosmetic products. FIG. 1 depicts a mesh net-mounted cosmetic container for use in a mesh-type moisture-release cushion cosmetic product according an embodiment of the present invention (100: cosmetic container, 110: container body, and 120: mesh net). The container body (110) of the cosmetic container (100) depicted in FIG. 1 was filled with the cosmetic composition on which the mesh net (120) was then mounted to manufacture a mesh net-type cushion cosmetic product. FIG. 2 is a photographic image of a mesh-type moisture-release cushion cosmetic product according to the present invention. When the mesh net was pressed, white (pearl) water drops appeared clearly.

Experimental Example 1: Comparison. Of Water-Drop Effect According to Type of Pearlescent Pigment

(12) The cosmetic compositions prepared according to the Examples could be observed with the naked eye to exhibit a water drop effect. FIG. 4 is a photographic image of a cross section of the loaded water-in-oil moisture release cosmetic composition according to the present invention.

(13) In order to compare water-drop effects according to types of pearlescent pigments, the composition of Example 3 which was high in dispersion stability as a result of the effective action of the emulsifier was used as a reference. Corresponding to the hollow-structured gloss pigment, 1% of each of Shimmer pearl A, Shimmer pearl B, non-coating TiO.sub.2 A, and non-coating TiO.sub.2 B were applied to the same process. Then, the compositions thus obtained were loaded to aluminum chalets in the condition of 80 C. and solidified at room temperature. Thereafter, observation was made of the formation of white drops while the surfaces were scraped.

(14) FIG. 5 is a photographic image showing comparison of degrees of white drop formation after the hollow pearl, the (non-hollow) Shimmer pearls, and the non-coating TiO.sub.2 were added in the same amount. As a result, the degree of formation of white drops was in the order of hollow-structured gloss pigment >Shimmer pearl >Non-coating TiO.sub.2. Water drops appeared most obviously from the hollow-structured gloss pigment. Although appeared, water drops were formed very slightly for the Shimmer pearls. No water drops were found from the non-coating TiO.sub.2.

(15) Experimental Example 2: Comparison of Water-Drop Effect According to Mesh Size and Shape

(16) In order to exhibit the moisture release characteristic of the formulation as much as possible, the effect was maximized by covering the formulation with a mesh net. The formation of white drops was observed according to mesh size and shape. As the mesh net shapes, a stocking-like mesh net the pore size of which could not be determined with the naked eye, a single mesh, a double mesh, and an embossed mesh were contemplated. Sizes with 0.1 mm-2 mm were applied to the mesh.

(17) According to a criterion for the uniform release of the composition and white drops, a use test was carried out and evaluated with the naked eye.

(18) FIG. 6 shows photographic images of the mesh-type moisture-release cushion cosmetic products of the present invention for comparison of water drop effects according to mesh size. In FIG. 6, No. 1 accounts for a single mesh type with a pore size of 1 mm, No. 2 for a single mesh type with a pore size of 0.1 mm, No. 3 for a double mesh type with a pore size of 0.1 mm, No. 4 for a single mesh type with a pore size of 0.5 mm, No. 5 for a thick mesh pattern with a pore size of 2 mm, and No. 6 for an embossed mesh type with a pore size of 2 mm.

(19) The best test result was obtained in the single mesh type, which is resilient. A thicker mesh, e.g., a double mesh, resulted in a smaller release amount of the cosmetic content and thus was not suitable for makeup cosmetic products. In addition, a denser mesh net made it more difficult to discharge the cosmetic content and allowed the elution of only white drops therefrom, thus resulting in an insufficient cosmetic effect. More of the content was applied to the face through a looser mesh net which is thus unsuitable for use in makeup cosmetic products. In FIG. 6, the mesh of No. 1 allowed the content and water to be most uniformly released in the white drop pattern. Through the mesh of No. 4, the content and water were smoothly released although to a lesser degree than the mesh of No. 1. Based on the test data, a resilient single mesh type with a pore size of 0.5-1.5 mm was determined to be the most suitable for releasing the content and forming white drops.

(20) Although some embodiments have been disclosed above, it should be understood that these embodiments are given by way of illustration only, and that various modifications, variations, and alterations can be made without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be limited only by the accompanying claims and equivalents thereof.
