[0022] In order to fully understand the drawings cited in the detailed description of the present invention, a brief description of each drawing is provided here.

[0023] Figure 1 The following are photographs showing the experimental results of Experimental Example 1. DETAILED DESCRIPTION

[0024] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which the invention belongs. Generally, the terms used in this specification are well known and commonly used in the art. Moreover, in the process of describing the embodiments of the invention, when it is judged that the specific description of the relevant known structure or function hinders the understanding of the embodiments of the invention, the detailed description thereof is omitted. In addition, the embodiments of the invention are described below, but the technical idea of ​​the invention is not limited thereto or limited thereto, and can be variously implemented by those of ordinary skill in the technical field to which the invention belongs by deforming it.

[0025] In this specification, when a component is referred to as "comprising" an element, unless otherwise expressly provided, it may mean that an element may further include other elements, instead of excluding any other elements. In this specification, the term "and / or" includes any and all combinations of one or more associated listed items.

[0026] According to an embodiment of the present invention, a powder cosmetic composition having a gradient effect is provided. The powder cosmetic composition according to an embodiment of the present invention may include spherical powder and oil.

[0027] Spherical powder has the property of evenly diffusing light in all directions, which can cover skin blemishes and also helps make cosmetics spread smoothly when applied to the skin.

[0028] In one embodiment, the spherical powder may include at least one selected from the group consisting of silica, polymethyl methacrylate (PMMA), polymethylsilsesquioxane (PMSQ), nylon, methyl methacrylate crosspolymer, and vinyl dimethicone / methicone silsesquioxane crosspolymer. However, the present invention is not limited thereto, and spherical powders conventionally used in the art may be used.

[0029] In an embodiment, the powder cosmetic composition may include 10.5% to 13.5% by weight of spherical powder based on the total weight of the above-mentioned powder cosmetic composition, specifically, 11% to 13% by weight of spherical powder. When the content of the spherical powder is lower than 10.5% by weight based on the total weight of the powder cosmetic composition, the powder agglomerates severely and the powder scatters less, which may result in obvious boundaries between different colors and inability to mix naturally. In addition, when the content of the spherical powder is 13.5% by weight based on the total weight of the powder cosmetic composition, the powder agglomerates less and the powder scatters severely, which may result in different colors mixing with each other, thereby reducing the gradient effect. However, the present invention is not limited thereto.

[0030] Oil can enhance the bonding and cohesion between powders, improve compression moldability, and prevent breakage when subjected to external impact, thereby minimizing powder scattering.

[0031] In an embodiment, the oil may include at least one of diisostearyl malate and dipentaerythrityl hexahydroxystearate / hexastearate / hexarosinate. By including diisostearyl malate and / or dipentaerythrityl hexahydroxystearate / hexastearate / hexarosinate, the specific volume value of the powder cosmetic composition can be appropriately adjusted, thereby providing an excellent gradient effect and minimizing the defect rate. However, the present invention is not limited thereto, and the powder cosmetic composition may also include various oils such as hexyl laurate, octyldodecyl myristate, cetyl ethylhexanoate, or isotridecyl isononanoate that can achieve a gradient effect.

[0032] In an embodiment, the powder cosmetic composition may include 5.0 wt % to 5.3 wt % of oil based on the total weight of the powder cosmetic composition. When the oil content is less than 5.0 wt % based on the total weight of the powder cosmetic composition, the powder agglomerates less and the powder scatters more seriously. In addition, when the oil content exceeds 5.3 wt % based on the total weight of the powder cosmetic composition, the powder agglomerates more seriously and the powder scatters less. However, the present invention is not limited thereto.

[0033] In an embodiment, the powder cosmetic composition may include 0.33 wt % to 0.67 wt % of diisostearyl malate based on the total weight of the above-mentioned powder cosmetic composition, and specifically, 0.4 wt % to 0.6 wt % of diisostearyl malate may be included. In addition, the powder cosmetic composition may include 0.63 wt % to 1.37 wt % of dipentaerythritol hexahydroxystearate / hexastearate / hexarosinate based on the total weight of the above-mentioned powder cosmetic composition, and specifically, 0.7 wt % to 1.3 wt % of dipentaerythritol hexahydroxystearate / hexastearate / hexarosinate may be included. By respectively including diisostearyl malate and / or dipentaerythritol hexahydroxystearate / hexastearate / hexarosinate within the above-mentioned content range, the specific volume value of the powder cosmetic composition can be appropriately adjusted to provide an excellent gradient effect and minimize the defect rate. However, the present invention is not limited thereto.

[0034] According to an embodiment, the powder cosmetic composition may further include plate-like powder. The plate-like powder may play a role of a support for the powder cosmetic composition to maintain its shape, and at the same time has the characteristics of being smooth and having excellent spreadability, thereby improving the feeling of use.

[0035] In an embodiment, the plate-like powder may include at least one selected from the group consisting of talc, boron nitride, mica, synthetic mica, sericite, alumina, barium sulfate, and kaolin. However, the present invention is not limited thereto, and the plate-like powder conventionally used in the art may be used.

[0036] In an embodiment, the powder cosmetic composition may include 50 wt % to 65 wt % of plate-like powder based on the total weight of the powder cosmetic composition. By including the plate-like powder within the above content range, the specific volume value of the powder cosmetic composition can be appropriately adjusted to provide an excellent gradient effect. However, the present invention is not limited thereto.

[0037] In an embodiment, the powder cosmetic composition may be a gradient composition. Here, the gradient composition may refer to a cosmetic composition that exhibits a gradient effect. In this case, when the composition is filled into a container before application, the color can be gradually and evenly changed, thereby enhancing the beauty of the appearance, and when applied to the skin, a vivid and diverse makeup effect can be exhibited.

[0038] In an embodiment, the specific volume of the powder cosmetic composition may be 1.2ml / g to 1.55ml / g, specifically, 1.25ml / g to 1.5ml / g, and more specifically, 1.3ml / g to 1.45ml / g. Wherein, the specific volume refers to the volume per unit mass at 25°C. By properly adjusting the type and content range of the spherical powder and / or oil, the powder cosmetic composition may have a specific volume within the above range. When the powder cosmetic composition has the above-mentioned specific volume range, the defect rate (for example, color spots and spot phenomena caused by mixing different colors, obvious boundaries between different colors, etc.) can be minimized during the compression molding process, and the colors can be gradually and naturally mixed to provide an excellent gradient effect. However, the present invention is not limited thereto.

[0039] According to an embodiment, the powder cosmetic composition may further include additives conventionally used in the art within the scope of not damaging the effects of the present invention. For example, the powder cosmetic composition may also include pigments, functional ingredients, emulsifiers, pH regulators, neutralizers, isotonic agents, surfactants, stabilizers, preservatives, preservatives, bactericides, moisturizers, barriers, skin conditioners, whitening agents, colorants, organic pigments, inorganic pigments, spices and vitamins, etc. Those skilled in the art can easily select the mixing amount of the above ingredients within the scope of not damaging the purpose and effects of the present invention.

[0040] According to the embodiment, the powder cosmetic composition can be made into a variety of products. For example, it can be made into blush, contour powder, brightening powder, primer, foundation, pressed powder, concealer or two-way foundation and other compressed powder cosmetics. However, the present invention is not limited thereto.

[0046] Table 1

[0047]

[0048] The specific preparation method is as follows. Except for the oil, the remaining ingredients are put into a Henschel mixer and mixed at a high speed. Subsequently, the oil is fully heated to about 70°C and mixed before being put into the Henschel mixer again and mixed at a high speed. Samples of different colors are placed on a plate through a gradient device and pressed with sufficient pressure to complete Example 1.

[0049] (2) Preparation of Comparative Examples 1 to 11

[0050] Comparative Examples of compositions according to the present invention were prepared using the ingredients listed in the following Table 2. The unit of the ingredient content in Table 2 is weight %.

[0051] Table 2

[0052]

[0053]

[0054] The specific preparation method is the same as that of Example 1. Comparative Examples 1 and 2 are compositions containing spherical powder in an amount outside the range of the examples, Comparative Examples 3 and 4 are compositions containing oil in an amount outside the range of the examples, Comparative Examples 5 to 9 are compositions using components outside the range of the examples as oils, and Comparative Examples 10 and 11 are compositions containing diisostearyl malate and dipentaerythritol hexahydroxystearate / hexastearate / hexarosinate in an amount outside the range of the examples.

[0055] Experimental example

[0056] (1) Experimental Example 1: Evaluation of Gradient Effect

[0057] In order to evaluate the gradient effect of the above-mentioned Example 1 and Comparative Examples 1 to 4, the surface appearance was analyzed, and the results are listed in Table 3 and Figure 1 Specifically, Figure 1 Part (a) is a photograph showing the surface appearance of Example 1, Figure 1 Part (b) and Part (c) are photographs showing the surface appearances of Comparative Examples 1 and 2, respectively.

[0058] The experimental method is as follows. For the samples of the above-mentioned embodiments and comparative examples, 30 evaluators in their 20s and 40s in each group were asked to apply the powder on the back of their hands or cheeks with their fingers or brushes (applicators), and then evaluate the degree of powder scattering and the degree of powder agglomeration. The feeling of the evaluation items was evaluated on a 10-point scale, with 1 point added for each level. The average of the total score was calculated and the deviation was deducted for evaluation. The closer the powder scattering score and the powder agglomeration score were to 5 points, the better the gradient effect was evaluated.

[0059] Table 3

[0060] Classification Powder scattering Powder agglomeration Example 1 5 5 Comparative Example 1 2 9 Comparative Example 2 9 2 Comparative Example 3 8 3 Comparative Example 4 3 8

[0061] The experimental results show that the surface appearance colors of Example 1 gradually blend naturally (refer to Figure 1 In (a) above, both powder scattering and powder agglomeration were rated 5 points, indicating an excellent gradient effect.

[0062] On the other hand, in the case of Comparative Example 1 containing a low content of spherical powder and Comparative Example 4 containing a high content of oil, a clear boundary between different colors appeared in the surface appearance, and the mixing was not natural (refer to Figure 1 In part (b), the powder is severely agglomerated and the powder is less scattered, which shows that the gradient effect is reduced.

[0063] In addition, in the case of Comparative Example 2 containing a high content of spherical powder and Comparative Example 3 containing a low content of oil, multiple colors were mixed with other colors in the surface appearance (refer to Figure 1 In part (c), there are fewer powder lumps and more powder scattering, which indicates that the gradient effect is reduced.

[0064] (2) Experimental Example 2: Determination of specific volume and defect rate

[0065] The specific volume and defect rate of the above-mentioned Example 1 and Comparative Examples 5 to 11 were measured, and the results are listed in Table 4.

[0066] The experimental method is as follows: The specific volume is measured by a specific volume meter, and the specific method is as follows, that is, a certain amount of sample is weighed and placed in a measuring cylinder, and after confirming the initial volume scale, it is pressed, and finally the final volume after pressing is confirmed, and the specific volume value is calculated.

[0067] As for the defect rate, 1000 products were mass-produced for each of the above-mentioned embodiments and comparative examples. Among the produced products, products with spots such as spots or spots due to the mixing of different colors or obvious boundaries between different colors were evaluated as defective products, and the defective product ratio among the 1000 products was calculated as the defect rate.

[0068] Table 4

[0069] Classification Specific volume (ml / g) Defect rate (%) Example 1 1.35 1.0 Comparative Example 5 1.68 33 Comparative Example 6 1.05 30 Comparative Example 7 1.55 25 Comparative Example 8 0.95 38 Comparative Example 9 1.22 15 Comparative Example 10 0.96 40 Comparative Example 11 1.72 34

[0070] The experimental results show that the specific volume measurement value of Example 1 is 1.35 ml / g, showing an appropriate specific volume, and the defect rate is 1%, indicating that the defect rate is minimized during the pressing process and can provide an excellent gradient effect.

[0071] On the other hand, in the case of Comparative Example 5 in which dipentaerythritol hexahydroxystearate / hexastearate / hexarosinate was replaced with diglycerol triisostearate, the specific volume was measured to be high at 1.68 ml / g, and color spots appeared in large numbers, and the defect rate was measured to be 33%. In addition, in the case of Comparative Example 6 in which polyisobutylene was used instead of dipentaerythritol hexahydroxystearate / hexastearate / hexarosinate, the specific volume was measured to be low at 1.05 ml / g, and boundaries between colors appeared in large numbers, and the defect rate was measured to be 20%.

[0072] In the case of Comparative Example 7 in which diisostearyl malate was replaced with diglyceryl triisostearate, the specific volume was measured at a high value of 1.55 ml / g, color spots slightly appeared, and the defect rate was measured at 25%. In the case of Comparative Example 8 in which diisostearyl malate was replaced with polyisobutylene, the specific volume was measured at a low value of 0.95 ml / g, the boundaries between colors appeared a lot, and the defect rate was measured at 38%.

[0073] In addition, in the case of Comparative Example 9 in which diisostearyl malate and dipentaerythritol hexahydroxystearate / hexastearate / hexarosinate were replaced with diglyceryl triisostearate and polyisobutylene, respectively, the specific volume measurement value was a lower 1.22 ml / g, a boundary between colors was slightly present, and the defect rate was measured to be 15%.

[0074] In addition, in the case of Comparative Example 10 including a low content of diisostearyl malate and a high content of dipentaerythritol hexahydroxystearate / hexastearate / hexarosinate, the specific volume measurement value was low at 0.96 ml / g, and the boundaries between colors appeared in large quantities, and the defect rate was measured to be 40%.
