Description

Solid Cosmetic Composition with Improved Stability and Method for Preparing Same}

The present invention relates to a solid cosmetic composition having excellent stability and a method for manufacturing the same, and more particularly, it is sensitive to the temperature of the skin, so that it is easily applied, adheres to the hand, or improves stickiness, and is not easily broken by external shock or melting at room temperature. It relates to a solid cosmetic composition with improved stability and a method of manufacturing the same.

In general, cosmetics with solid formulations have excellent adhesion, excellent ability to cover skin flaws, and have excellent expressiveness of color, so they are used as various types of cosmetics such as foundation, two-way cake, lipstick, and shadow. have. These solid cosmetics are prepared by mixing various types of powders for expressing color while covering the defects of the skin with the underlying wax and oil.

On the other hand, most of the waxes used as a main material in such solid cosmetics remain in a solid state at room temperature, but as the temperature increases, they melt and change into a liquid state, so that the formulation of the solid cosmetics is not stable. In order to solve such a problem, Korean Patent Registration No. 10-1055164 discloses an oil-dispersed makeup cosmetic composition having a smoother application by changing from a solid to a gel state by high coverage and applying force without using wax. Although disclosed, there is a problem that excessive oil is used instead of using wax, so that the formulation of the cosmetic is soft, and when applied to the skin, there is a problem that it is very shiny and easily removed. In addition, there is a problem of sweating due to oil, and the formulation is softened as the temperature increases due to a low melting point.

Therefore, there is a growing need for cosmetics that have a stable formulation, less gloss, and excellent gloss while simultaneously using wax and oil that can improve the melting point, and oil and wax are simultaneously used as in Korean Patent No. 10-0698941. Various technologies are being studied for used cosmetics.

Korean Patent Registration No. 10-0698941 discloses a cosmetic composition containing wax, colorants, and volatile oils having a melting point of 60 to 100°C. However, as a mixture of wax and volatile oil, There was a problem that the formulation was unstable because each component was separated. In addition, there is a problem in that the glossiness is deteriorated and the spreadability is deteriorated due to excessively added wax to improve the melting point.

In addition, the above solid cosmetics are mainly used for color cosmetics or sunscreens, and for cosmetics containing skin-effective ingredients, the desirable melting point range is narrow and it is difficult to maintain a solid formulation while containing skin-effective ingredients. It is a situation that is not being utilized.

Experimental example: solid cosmetic composition physical property test

1(a) and (b) are images comparing the appearance of the solid stick-type cosmetic products of Example 1 and Comparative Examples 1 and 2, respectively.

In Fig. 1(a), the solid stick of Example 1 has a smooth cross section and is stably positioned in the container, but the solid stick of Comparative Example 1 has a non-smooth surface and a gap is formed in the rim, indicating that the formulation is unstable. .

When the solid stick was pushed out in FIG. 1(b), the stick of Example 1 had a clean cross-section as it was raised upward, so that the formulation was stable. On the other hand, the stick of Comparative Example 2 can be confirmed that the formulation is soft, the surface is not smooth, and the shape is collapsed.

2(a) and (b) show the appearance after applying a solid stick cosmetic product to the skin.

In Fig. 2(a), the solid stick of Example 1 is evenly applied to the skin, and there is no greasy or stickiness.

On the other hand, in the solid stick of Comparative Example 3, it can be seen that the lump is oozing out during the application process and the formulation is collapsed.

In Fig. 2(b), it was confirmed that the shape of the solid stick of Comparative Example 4, which used an excessive amount of sunflower seed oil and a small amount of bead wax, and used an excessive amount of sorbitan olivate, was completely collapsed in a single use. .

It is shown in Figure 3 to compare the appearance of the solid stick according to the manufacturing method.

In FIG. 3, the solid stick prepared by the method of the present invention was prepared with a smooth and smooth surface without lifting, but the stick of Comparative Example 6 in which the stick of Comparative Example 5 and the tissue were set at a high melting temperature for a short time at a low temperature was It can be seen that the rim is raised or an oil band is formed.
