Description

The present invention relates to multicolor solid cosmetics.

Base makeup is makeup that is used to make the skin look beautiful. Base makeup cosmetics include makeup bases that make foundation easier to apply, foundations that even out skin tone, and concealers that make blemishes and dark circles less noticeable. Furthermore, base makeup cosmetics generally have a composition of a single color such as skin color.

In recent years, in order to make the appearance of cosmetics such as foundations attractive, solid cosmetics have been formed by filling with multiple colors (see Patent Document 1, etc.). These multicolored solid cosmetics are usually used by mixing compositions of multiple colors when applied to the skin. It has also been reported that a good sense of depth can be imparted to the skin by using a multicolor solid cosmetic in which the multicolor composition mixed here includes a combination of an advancing color and a receding color (patented). References 2, 3).
In addition, in order to obtain the desired multicolor effect from the beginning to the end of use of the multicolor solid cosmetic, the horizontal arrangement of the coloring compositions of each color is maintained in the same way in the upper and lower vertical directions. A multicolored solid cosmetic has also been disclosed (Patent Document 4).

Japanese Patent Application Publication No. 2017-178878 JP2019-064988A JP2020-007242A JP2020-186210A

In recent years, there has been a trend towards makeup that covers imperfections while giving a natural finish and a glossy feel. However, conventional multicolored solid cosmetics have not always provided a satisfactory glossy feeling on the skin after application. In particular, oil gel formulations tend to cause shine, making it difficult to obtain a desired glossy feel.

ADVANTAGE OF THE INVENTION The present invention provides an oil gel type multicolored solid cosmetic that has a glossy, transparent, and natural finish. Furthermore, in a preferred embodiment, the resulting color balance is maintained even as the product is used, so that the above-mentioned effects of gloss, transparency, and natural finish are also maintained.

This is a photograph taken from directly above of cosmetics prepared in four colors: red, yellow, green, and white. This is a photograph taken from directly above of cosmetics prepared in three colors: red, yellow, and green. 2 is a graph showing the presence rate of ultra-high brightness areas on skin to which Example 3 and Comparative Example 2 were applied.

Hereinafter, specific embodiments of the present invention will be described.
In the multicolor solid cosmetic of the present invention, a plurality of coloring compositions are arranged regularly or randomly to form a multicolor solid cosmetic. In this specification, the direction in which the plurality of coloring compositions are arranged is the direction in which they are applied to the skin via a medium or directly, and is usually a horizontal direction parallel to the opening surface of the container. Specifically, if it is a cake-type cosmetic, it will be applied in the direction of the plane where the puff is slid to transfer the cosmetic onto the puff, and if it is a stick-type cosmetic, it will be applied in the direction of the application plane where it is applied to the skin. A plurality of colored compositions are arranged.
In addition, "solid" here means that there is no fluidity|liquidity at room temperature (25 degreeC).

The multicolor solid cosmetic is not particularly limited as long as it consists of a coloring composition of three or more colors, and may have three colors, four colors, or five or more colors. In some cases, ten or more colors may be used, but if the number of colors in each coloring composition of the cosmetic is too large or too small, the sense of depth will be lost, and the cosmetic may be perceived as a single color and flat. Therefore, it is preferable that the number of colors is less than 10.
The reason for this is that skin color is not constant, but varies in brightness and hue depending on location, and cosmetics are also a collection of different colors, so it is possible to express skin color by dispersing the colors appropriately. It is thought that a sense of depth can be obtained.
Further, the multicolored solid cosmetic of the present invention preferably exhibits a skin color when applied to the skin.

Multicolored solid cosmetics are divided into multiple coloring compositions by color, but the number of multiple coloring compositions arranged here (number of divisions, number of spots) is greater than the number of colors of the coloring compositions. If so, it is not particularly limited, and the upper limit is preferably 100 or less.
The size (area of the compartment) of each colored solid composition is not particularly limited, but the ratio of the total area of each colored solid composition with the largest area to the colored solid composition with the smallest area is 1.5 or less, and 1 It may be less than .4, may be less than 1.3, and may be less than 1.25, and it is preferable that the sizes of the respective colored solid compositions are approximately the same. Since the area of each color is approximately the same in this way, when applied to the skin, a natural skin color is exhibited, and a desirable feeling of gloss and transparency is exhibited. If there is a large variation in the area of each color, the skin will have an unnatural finish after application. In particular, if the area of the white colored solid composition is too small, the gloss and transparency will be impaired.
In addition, the area of the minimum colored solid composition may be 0.04 cm2 ^or more, may be 0.25 cm2 or more, and may be 3 ^{cm2 or} less, from the viewpoint of good depth, and may be 1.5 cm2 or more. It may be ² or less.

In this specification, the "area" of a cosmetic or a composition refers to the area of the surface (surface) of the cosmetic or composition filled in a container or the like that is exposed from the container. Usually, the surface on which the puff slides, or the surface on which it is applied when directly applied to the skin, corresponds to the "surface."

The multicolored solid cosmetic of the present invention has a plurality of colored compositions on the plane on which the puff slides, or on the application plane when directly applied to the skin, and does not have a single color. As a result, colors are unevenly distributed in the cosmetic film, thereby covering defects and providing a natural finish and sense of depth. Note that uneven distribution of color refers to large variations in the content area ratio of pigments contained in each of a plurality of coloring compositions (ratio of pigments in a certain area) when a cosmetic is applied.
In addition, as will be described later, the presence of white among the colors that are unevenly distributed in the cosmetic film forms many color gradations including ultra-high brightness areas on the skin, giving it a good sense of gloss and transparency.
Normally, when you try to cover up skin imperfections, you tend to end up with an unnatural finish that makes you feel the presence of a makeup film, but the multicolored solid cosmetic of the present invention has a natural finish with a glossy and transparent feel and coverage. It is possible to achieve both.

The multicolor solid cosmetic of the present invention includes a plurality of coloring compositions including white, at least one advancing color, and at least one receding color.

Advancing color is a general term for colors that stand out from the background color and appear to be closer to each other, and are usually classified as red-purple, red, red-yellow, yellow, and yellow-green in the Munsell color system. selected. Generally, colors have high brightness and high saturation. Specifically, representative colors include red, orange, and yellow.
A receding color is a general term for a color that appears to recede from the background color, and is usually selected from colors classified as green, blue-green, blue, blue-violet, and violet in the Munsell color system. Generally, colors have low brightness and low saturation. Specifically, representative colors include green, blue-green, blue, blue-violet, and violet.

The white colored solid composition exhibits white color and exhibits an L* value of preferably 90 or more, more preferably 95 or more, and still more preferably 98 or more. Usually substantially free of colored pigments.
"Substantially free" means preferably 0.01% by mass or less, more preferably 0.001% by mass or less of the entire composition.

In the multicolor solid cosmetic of the present invention, the surface area occupied by the white colored solid composition is 15 to 40%, more preferably 20 to 35%, and even more preferably 20 to 35% of the entire surface of the cosmetic. is 25-30%.
By setting this range, when mixing multiple colors, the white content (uneven distribution amount) will be appropriate, and it will be possible to give good gloss and transparency to the skin to which the cosmetic is applied. .

The content of the pigment titanium oxide in the white colored solid composition is preferably 1 to 20% by mass, more preferably 5 to 20% by mass, and even more preferably 10 to 15% by mass based on the total amount of the white colored solid composition. It is.
By setting it within such a range, a natural finish can be imparted to the skin to which the cosmetic has been applied. If the content of the pigment titanium oxide in the white colored solid composition is too large, the overall brightness may become too high when the cosmetic is applied, making it difficult to obtain an appropriate skin color. In addition, if you try to lower the brightness while increasing the content of the titanium oxide pigment in the white colored solid composition, it will be necessary to increase the amount of other pigments (red, yellow, etc.), resulting in uneven color when the cosmetic is applied. may occur.

In order for a multicolored solid cosmetic to exhibit a skin color on the skin, it is preferable to include black powder, but if black powder is blended into a coloring composition containing red, red-yellow, and/or yellow, the appearance becomes dull. There is a tendency. Therefore, it is preferable that black powder is not substantially blended into the coloring composition containing the advancing color. Note that "substantially not blended" means that the coloring composition containing the advanced color is not blended to the extent that the brightness of the coloring composition is dulled. % or less, 0.5% by mass or less, 0.3% by mass or less, 0.1% by mass or less, 0.05% by mass or less , 0.01% by mass or less.

On the other hand, even if black powder is blended into a colored composition containing a receding color, the gorgeous appearance is unlikely to be lost. Therefore, it is preferable to blend black powder into a colored composition that includes receding color. In this case, the content of the black powder added to the coloring composition containing blue, blue-green, and/or green is usually 0.05% by mass or more, preferably 0.1% by mass or more based on the total amount of the coloring composition. The content is usually 2.0% by mass or less, preferably 1.5% by mass or less.
Examples of black powder include black iron oxide, carbon black, titanium black, and the like.

The plurality of colored solid compositions in the multicolored solid cosmetic of the present invention preferably satisfy the following conditions (a) to (d) when their G'' (loss modulus) is measured over temperature.
(a) All of the colored solid compositions have a G'' of 2.0 to 60 in the entire range of 70°C to 80°C (also referred to as "first temperature range" or "first region"). It's within.
(b) Over the entire range of 70°C to 80°C, the average amount of change in G''(ΔG''/Δt, Δt=1°C) for multiple colored solid compositions when the temperature rises by 1°C is - It is within the numerical range of 0.80 to -15.
(c) All colored solid compositions have a G'' of 0.10 to 8.0 over the entire range of 81°C to 130°C (also referred to as "second temperature range" or "second temperature range"). Within the numerical range.
(d) In the entire range of 81°C to 130°C, when the temperature rises by 1°C, the average change in G''(ΔG''/Δt, Δt=1°C) of multiple colored solid compositions is -0 It is within the numerical range of .00 to -0.50.

In addition, the amount of change in G''(ΔG'' when the temperature in conditions (b) and (d) above rises by 1°C is
/Δt, Δt=1° C.) is the slope of the temperature change graph of G″. Moreover, the average of a plurality of colored solid compositions is the average calculated for the amount of change (inclination) of a plurality of colored solid compositions at the same temperature.

In the present invention, G'' is a value measured using a rheometer AR-G2 (manufactured by TA Instruments).

In this way, the plurality of coloring compositions satisfy predetermined viscoelastic properties in each of the first and second temperature regions, and specifically, the change in G'' over temperature in the first region is relatively large, and the Because the change in G'' over temperature in the two regions is relatively small, the arrangement of the coloring compositions of each color constituting the multicolor solid cosmetic in the planar direction is maintained in the same way in the upper and lower vertical directions. structure can be formed. Further, since the filling of the coloring composition of each color in the planar direction proceeds uniformly, it becomes easier to fill the coloring composition so that the area of each color is approximately the same.
More specifically, the disclosure of JP 2020-186211 can be referred to, but when G'' of the plurality of colored compositions satisfies the above conditions (a) to (d), the colored composition of the plurality of colors This makes it easier to arrange the multicolored solid cosmetic material in a plane direction evenly. Moreover, the same arrangement as the appearance can be easily maintained both above and below the multicolor solid cosmetic in the vertical direction. In other words, the boundaries of each coloring composition are not disturbed, and the intended arrangement is maintained vertically upward and downward, so even if the cosmetic application progresses, the effect of gloss, transparency, and natural finish can be maintained. You can continue to get it.
If G'' of the plurality of coloring compositions does not satisfy the above range, even if the appearance of the arrangement in the planar direction is uniform, the arrangement in the planar direction will be different between the upper and lower parts in the vertical direction, or the arrangement in the planar direction will be different. The appearance may become uneven.

In the multicolor solid cosmetic of the present invention, it is preferable that the arrangement of the coloring compositions of each color constituting the same in the plane direction is maintained in the same way above and below in the vertical direction. As a result, even if the use of multicolored solid cosmetics progresses and the remaining amount of cosmetics decreases, it is possible to continue to maintain and provide the same desired application color as at the beginning.

``Maintaining the same desired applied color as originally'' is due to the fact that there is a small difference in the color of the cosmetic transferred to the applicator and the skin between the initial use of the cosmetic and the advanced use. It can be confirmed. More specifically, the multicolored solid cosmetic is divided into five equal layers, and the top surface of each layer, the top layer (first layer) and the bottom layer (fifth layer), is coated with a wet urethane repellent. This can be confirmed by a test in which the surface of the multicolored solid cosmetic is rubbed with a 52 x 44 x 8.5 mm cosmetic puff made of water-treated material under a load of 2.9 N. Note that "thickness" here refers to the length of the cosmetic in the vertical direction, and "layer" refers to the cosmetic divided in the horizontal direction.
In the multicolored solid cosmetic of the present invention, in the test, the chromaticity difference ΔE between the chromaticity of the cosmetic rubbed off with the first layer and the chromaticity of the cosmetic rubbed off with the fifth layer is preferably It is 2.0 or less, more preferably 1.5 or less, and even more preferably 1.0 or less. The chromaticity difference ΔE is an index that numerically represents the color difference when two arbitrary colors are expressed as Lab values, and can be calculated using the following equation.
ΔE _ab = [(ΔL) ² + (Δa) ² + (Δb) ² ] ^1/2
The number of times each layer is rubbed and measured is preferably 10 or more times, more preferably 15 times or more, and it is preferable to use the average chromaticity of each layer when calculating the chromaticity difference.

The cosmetic puff made of wet urethane water-repellent material and measuring 52 x 44 x 8.5 mm is a popular cosmetic puff used in the market, and the load when rubbing off the cosmetic is 2.9N. This assumes the load normally applied when a woman rubs off cosmetics with a puff.
In addition, the chromaticity difference of cosmetics can be determined by, for example, applying the rubbed off cosmetics onto an acrylic white board using a puff used to rub off the cosmetics, and then applying the spectral color to the makeup film on the acrylic white board. The color can be measured by measuring the color using a meter (Nippon Denshoku SD5000, D65 light source).
In addition, the demonstration that when G'' of a plurality of coloring compositions satisfies the above conditions (a) to (d), the same desired coating color as originally applied in a multicolored solid cosmetic is maintained is disclosed in JP-A No. Please refer to the disclosure of Publication No. 2020-186211.

The multicolored solid cosmetic of the present invention can be produced by filling a container such as a metal plate with the plurality of colored compositions.
The temperature conditions during filling are preferably 70 to 130°C, more preferably 80 to 100°C, and still more preferably 85 to 95°C. Usually, after filling, the solid cosmetic is cooled to room temperature to obtain a solid cosmetic.
When manufacturing the multicolor solid cosmetic of the present invention, it is preferable that the plurality of coloring compositions are filled into a container at the same time. Here, "simultaneously" means that the start and end of filling the container are at the same timing. More preferably, the filling speeds of the plurality of coloring compositions are approximately the same.

The shape of the plurality of coloring compositions in the direction of the arrangement surface is not particularly limited, and may be any shape, such as round, rectangular, polygonal, amorphous, or marbled. From the viewpoint of design, it is preferable to have at least a portion or the entire portion arranged in a marble shape. Moreover, these may be arranged regularly or randomly. From the viewpoint of keeping the chromaticity of the cosmetics rubbed off with a puff constant, a plurality of coloring compositions having approximately the same shape may be regularly arranged, for example, a spiral marble pattern having approximately the same width (Figure 1). Examples include layouts such as a checkerboard pattern or a checkered pattern.

When the multicolored solid cosmetic of the present invention is cake-type, it is usually round or substantially rectangular in consideration of compact storage, but it is not limited to this. Here, the term "substantially rectangular" refers to a shape that is close to a rectangular shape, but includes a shape with four rounded corners. Note that the round shape has the advantage that the solid cosmetic can be used evenly to the end. The thickness of the cake is also 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 about 1.0 cm or less. It's fine.
On the other hand, in the case of a stick type, it is usually stick-shaped, and its length and diameter are set as appropriate.

The multicolor solid cosmetic of the present invention is in the form of an oil gel.
Further, embodiments of the multicolor solid cosmetic of the present invention include foundation, concealer, cheek color, eye color, etc., and are not particularly limited, but foundation and concealer are more preferred. Concealer may be applied before or after foundation, but if it is applied afterwards, it will be more effective in giving a sense of shine, transparency, and depth. This is preferable because it also suppresses the wobbling of the cosmetic film (Japanese Patent Application Laid-open No. 2020-007242).

<Preparation of multicolor solid cosmetic>
According to the formulation shown in Table 1, multicolored solid cosmetics consisting of four colored colored compositions were prepared.
First, A was heated to 105 to 110°C and stirred and mixed, and after adjusting the temperature to 85 to 90°C, B was added and stirred and mixed to prepare colored compositions of each color.
G'' of each colored composition before filling was measured using a rheometer AR-G2 (TA Instru
(manufactured by Ments Inc.) under the following conditions, and it was confirmed that the above-mentioned conditions (a) to (d) were satisfied.
Program: Temperature sweep Vibration stress: 30Pa
Measurement temperature: 20℃~150℃
Gap: 1000μm
Coloring compositions of four colors were simultaneously poured into a circular gold plate with a diameter of 5 cm at 85° C. to obtain a multicolored solid foundation divided into four colors as shown in the photograph shown in FIG. In addition, the ratio of the area of each of the four coloring compositions on the surface of the cosmetics of the smallest color to the largest color was calculated from the number of pixels of each color measured from a digital photograph taken from directly above the cosmetics. . Further, as Comparative Example 2, a multicolored solid cosmetic consisting of a colored composition of three colors excluding white was similarly prepared as shown in the photograph shown in FIG.

<Sensory evaluation>
When each cosmetic is applied to the skin using a puff that has been wiped around the surface of the product, it is evaluated whether it has a natural skin tone, whether it has a glossy feel, whether it has a sense of transparency, and whether it has a sense of transparency. ``Does it have coverage?'', was evaluated by an experienced evaluator on a four-level scale (◎: very good, ◯: good, △: average, ×: bad).
The results are shown in Table 2.

Comparing Example 3 and Comparative Example 2, it is recognized that the presence of white in the plurality of colored solids provides an excellent gloss and transparency, resulting in a more natural finish.
From the results of Comparative Example 1 and Examples 1 to 4, by setting the ratio of the area of each coloring composition of the area of the largest color to the area of the smallest color to be 1.5 or less, glossy and natural transparency can be achieved. It can be seen that a certain finish is good.

<Measurement of ultra-high brightness area>
Each cosmetic of Example 3 and Comparative Example 2 was applied to the subject's face, and a photograph of the front of the subject's face was taken in standard light photography mode using a skin measurement device VISIA-Evolution (Canfield Scientific Inc.). did. The test subject wore a gray cape and with his eyes closed, a photograph was taken along with a color chart for image correction (CASMATCH). In the obtained photograph, a 500×500 pixel area was cut out below the eyes and next to the nostrils, and the brightness of each pixel in the area was measured at 250 gradations. The ratio of the number of pixels in the ultra-high brightness area (230 to 250 gradations) included in the area was calculated as the existence rate of the ultra-high brightness area.
The results are shown in Figure 3. Compared to Comparative Example 2, which is a multicolored solid cosmetic that does not contain white, Example 3, which is a multicolored solid cosmetic that contains white in a plurality of colored solids, has a higher abundance of ultra-high brightness regions and has a clearer feel. It was recognized that it can produce a certain glossy feeling.
