Description

The present invention relates to multicolored solid cosmetics.

Foundation is a base make-up cosmetic that has the function of making the skin look beautiful, and is a cosmetic that mainly exhibits skin color. As the foundation, there are dosage forms such as powder solid foundation, emulsified solid foundation, and oil solid foundation.

In order to make the appearance of the cosmetic itself attractive, a solid foundation is formed by multicolor filling (see, for example, Patent Document 1).
Further, since the selection of the coating color is very important especially in the foundation, a multicolor filling foundation in which the appearance color of the main part and the expected coating color are substantially the same has been proposed, and a plurality of filling compositions have been proposed. A foundation that keeps the chromaticity difference of the appearance color below a certain level is disclosed (see, for example, Patent Document 2).

As described in Patent Document 2, the selection of the coating color is very important in the foundation. Therefore, although there are the above proposals, foundations that still exhibit skin color are the mainstream.

Japanese Unexamined Patent Publication No. 2002-154930 Japanese Unexamined Patent Publication No. 2014-005262

Certainly, a foundation that exhibits a flesh color is advantageous from the viewpoint of selecting a coating color, but as a result of the examination by the present inventors, the foundation that exhibits a flesh color loses the original vividness of the pigment and the pigment, and therefore the depth. I came up with the problem that it is difficult to get a feeling.
An object of the present invention is to provide a multicolored solid cosmetic that can give a good sense of depth.

The present inventors have proceeded with research to solve the above problems, and have found that it is effective to combine advance color and receding color in order to give a sense of depth. However, even when the advanced color and the receding color are combined, if each colored solid composition is present as a large spot on the arrangement surface of each colored solid composition constituting the solid cosmetic, it is applied to the skin. When it was applied, it was recognized as color unevenness, and when it was present in a small spot, a sufficient sense of depth could not be obtained. Therefore, we have come up with the idea that a good sense of depth can be obtained by setting an appropriate number of spots on the surface of the colored solid composition of the multicolored solid cosmetics, and completed the present invention.

The present invention is a multicolored solid cosmetic in which a plurality of colored solid compositions are regularly arranged or arranged at random.
The plurality of colored solid compositions include at least one advanced color and at least one receding color.
A multicolored solid cosmetic having a number of colored solid compositions of more than 20 and less than 100 on the arrangement surface of the plurality of colored solid compositions.

In the present invention, the advanced color is selected from the colors classified into red, red-yellow, and yellow in the Mansell color system, and the receding colors are green, blue-green, and blue in the Mansell color system. It is preferably selected from the colors to be classified.
Further, it is preferable that the number of colored solid compositions is 30 or more and 95 or less on the arrangement surface of the plurality of colored solid compositions.
Further, it is preferable that the plurality of colored solid compositions are composed of less than 10 colors.
Further, it is preferable to have at least a part of the portion where the plurality of colored solid compositions are arranged in a marble shape.
Further, it is preferable that the foundation exhibits a skin color when applied to the skin.
Further, it is preferable that the pigment titanium oxide is contained in an amount of 1% by mass or more and 40% by mass or less with respect to the total amount of the multicolor solid cosmetics.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a multicolor solid cosmetic that can exhibit a good sense of depth and can achieve a lively skin appearance and a transparent skin appearance.

It is a schematic diagram which shows the schematic shape of the cosmetics prepared in Example 1. FIG.

Hereinafter, specific embodiments of the present invention will be described.
In the multicolored solid cosmetics according to the present embodiment, a plurality of colored solid compositions are regularly arranged or arranged at random to form a multicolored solid cosmetics. In the present specification, the arrangement direction of the plurality of colored solid compositions is the direction of application to the skin via a medium or directly. Specifically, in the case of a solid foundation, a plurality of colored solid compositions are applied in a plane direction in which the puff is slid to transfer cosmetics onto the puff, and in the case of a stick foundation, in a plane direction in which the puff is applied to the skin. Is placed.

The multicolor solid cosmetic is not particularly limited as long as it is composed of a colored solid composition having two or more colors, and may be two colors, three colors, four colors, or five or more colors. .. In some cases, 10 or more colors may be used, but it is preferable that the number of colors is less than 10 from the viewpoint of giving a good sense of depth to the cosmetic. Further, the multicolor solid cosmetic of the present embodiment is a cosmetic that exhibits a skin color when applied to the skin.

The multicolor solid cosmetic according to the present embodiment is a cosmetic that exhibits a good sense of depth. This was clarified by the following experiment. Hereinafter, an experiment conducted to clarify the difference in the sense of depth using the powder foundations of Example 1, Comparative Example 1 and Comparative Example 2 described later will be shown. The powder foundation of Example 1 was evaluated to give a feeling of depth to the skin when applied to the skin, and Comparative Example 1 and Comparative Example 2 were evaluated to give a feeling of depth to the skin. Is.

<Experiment 1: Uneven distribution of pigments on a micro basis>
The powder foundations of Example 1 and Comparative Example 1 described later were prepared.
A film was uniformly formed by a 0.5 mil doctor blade using Polyjoint JN (manufactured by Taisei Fine Chemical Co., Ltd.). The powder foundations of Example 1 and Comparative Example 1 were uniformly applied thereto, and these were used as test samples. Four random images were taken from each test sample to analyze the degree of uneven distribution of the pigment. A video microscope (KEYENCE HVX1000) was used for image analysis.
As a result of visually observing the 600-fold image, it was confirmed that the pigment was unevenly distributed in the test sample coated with the foundation of Example 1. On the other hand, in the foundation of Comparative Example 1, uneven distribution of pigments could not be confirmed.
In addition, the pigment content area ratio (ratio of the pigment in a certain area) (%) in the test sample was calculated for the red pigment and the yellow pigment, and the standard deviations of the content area ratio were compared. The results are shown in Table 1.

From Table 1, it was confirmed that the foundation of Example 1 had a large variation in pigments, that is, the pigments were unevenly distributed at the time of application.

<Experiment 2: Monochromatic image histogram at the time of application>
The powder foundations of Example 1, Comparative Example 1 and Comparative Example 2 described later were prepared.
A test sample prepared by the same method as in Experiment 1 was imaged, and the obtained digital image was converted into an RGB image by using Photoshop CS6 to convert the color distribution of the pixels constituting the image into an RGB image, and a fixed area (200 x 200 pixels). A histogram analysis was performed on the subject. Since the B image has the largest standard deviation as compared with the R image and the G image, a histogram analysis was performed using the B image to evaluate the color variation. The results are shown in Table 2.

From Table 2, it can be understood that the powder foundation of Comparative Example 1 has a small color variation and the powder foundation of Comparative Example 2 has a large color variation. On the other hand, in Example 1, it can be understood that the color variation is moderately large.

<Experiment 3: Observation of puffs to which cosmetics have been transferred>
The powder foundations of Example 1, Comparative Example 1 and Comparative Example 2 described later were prepared.
Each foundation was transferred to a 4 cm × 5 cm puff, the puff after the foundation transfer was imaged, and a histogram analysis was performed from the digital image using the B image in a certain area in the same manner as in Experiment 2, and the color variation was evaluated. .. The results are shown in Table 3.

From Table 3, it was suggested that by increasing the color variation of the foundation transferred to the puff, a foundation exhibiting a good sense of depth can be obtained. Based on these suggestions, it was found that a good sense of depth can be obtained by increasing the number of spots when transferred to the puff, that is, the number of colored solid compositions on the plane on which the puff is slid in the solid cosmetics. Obtained.

<Experiment 4: Change in depth depending on the number of spots>
In response to the above experiments 1 to 3, an experiment was conducted to see how the sense of depth changes by changing the number of spots of the foundation transferred to the puff and the number of spot colors. The colors that make up the spot are as follows. In addition, each spot contained at least one kind of advanced color and at least one kind of receding color.
2 colors: orange, green 3 colors: red, yellow, blue 4 colors: red, yellow, blue, green 8 colors: red, orange, yellow, yellow green, blue, green, gray, white 10 colors: red, pink, Orange, yellow, yellow-green, blue, green, bluish-purple, white, gray

Each foundation transferred to the puff was applied to the subjects, and the sense of depth was evaluated. The evaluation was conducted by 10 panelists, and the evaluation criteria are as follows. The results are shown in Table 4.
XXX: Feels flat with a single color.
XX: Recognized as color unevenness.
X: Recognized as slightly uneven color.
Δ: I feel a little depth.
○: Feel the depth.
◎: I feel a lot of depth.

From Table 4, it can be understood that when the number of spots is more than 20 and less than 100, the foundation exhibits a good sense of depth. When the number of spots is 20 or less, the result is that color unevenness is recognized. On the contrary, if the number of colors is too large, the sense of depth is lost, and the result is that a single color is recognized as flat. Also, it can be understood that the number of colors is preferably less than 10.
The reason for this result is that the skin color is not constant and the brightness and hue vary depending on the location, and even in cosmetics, it is a collection of different colors, and the skin color is appropriately dispersed. The present inventors consider that the expression provided a good sense of depth.

From the above, the multicolored solid cosmetics of the present embodiment include at least one advance color and at least one receding color in the plurality of colored solid compositions, and are colored on the arrangement surface of the plurality of colored solid compositions. A multicolored solid cosmetic having more than 20 and less than 100 solid compositions.

Advance color is a general term for colors that appear to stand out from the background color and appear to be close to each other. Be selected. Generally, it is a color with high lightness and high saturation. Specifically, red, orange, yellow and the like are typical colors.
The receding color is a general term for colors that appear to be recessed from the background color, and is usually selected from the colors classified into green, turquoise, blue, bluish purple, and purple in the color system of Mansell. Generally, it is a color with low lightness and low saturation. Specifically, green, blue-green, blue, bluish-purple, purple and the like are typical colors.

The number of colored solid compositions in the multicolored solid cosmetics is preferably 25 or more, more preferably 30 or more, further preferably 35 or more, and particularly preferably 40 or more. Further, it is preferably 95 or less, and more preferably 90 or less.
The size (area) of each colored solid composition is not particularly limited, but the area ratio of the colored solid composition having the maximum area to the colored solid composition having the minimum area may be 5 or less, and may be 4 or less. It may be 3 or less, and may be 2 or less, and it is preferable that the sizes of the colored solid compositions are substantially the same. Further, the area of the minimum colored solid composition may be 0.04 cm ² or more, 0.25 cm ² or more, 3 cm ² or less, and 1.5 cm from the viewpoint of good depth. It may be ² or less.

In order for the multicolored solid cosmetic to exhibit a skin color on the skin, it is preferable to contain a black powder, but when the black powder is added to the colored solid composition containing red, reddish yellow, and / or yellow, the appearance is obtained. It tends to be dull. Therefore, it is preferable that the black powder is not substantially blended in the colored solid composition containing the advanced color. In addition, "substantially not blended" is intended not to blend to the extent that the vividness of the colored solid composition including the advanced color is dull. For example, the black powder is 0. It may be 8% by mass or less, 0.5% by mass or less, 0.3% by mass or less, 0.1% by mass or less, and 0.05% by mass or less. It may be 0.01% by mass or less.

On the other hand, even if the black powder is blended with the colored solid composition containing the receding color, the gorgeous appearance is not easily lost. Therefore, it is preferable to add the black powder to the colored solid composition containing the receding color. In this case, the content of the black powder to be blended in the colored solid composition containing blue, blue-green, and / or green is usually 0.05% by mass or more, preferably 0.1% by mass, based on the total amount of the colored solid composition. % Or more, and usually 2.0% by mass or less, preferably 1.5% by mass or less.

The shape of the plurality of colored solid compositions in the arrangement surface direction is not particularly limited, and may be any of a round shape, a rectangular shape, a polygonal shape, an amorphous shape, a marble shape, and the like. From the viewpoint of design, it is preferable to have at least a part of the portion arranged in the marble shape. Further, these may be arranged regularly or at random. From the viewpoint of keeping the chromaticity of the cosmetic scraped by the puff constant, a plurality of colored solid compositions having substantially the same shape may be regularly arranged.

In the case of a powder foundation, the shape of the multicolored solid cosmetic according to the present embodiment is usually round or substantially rectangular in consideration of compact storage, but is not limited thereto. Here, the substantially rectangular shape means that the shape is close to the shape of a rectangle, but includes those having four rounded corners. The round shape has the advantage that the solid cosmetics can be used evenly until the end. Further, the thickness of the powder foundation is not particularly limited, and may be usually 0.1 cm or more, 0.2 cm or more, and usually 2.5 cm or less, preferably 1.0 cm. It may be as follows.
