Description

  The present invention relates to a multicolor powdered solid cosmetic, and more particularly to a multicolored solid foundation.

The foundation is a base makeup cosmetic that functions to make the skin look beautiful, and is a cosmetic that mainly exhibits skin color. As the foundation, there are dosage forms such as a powdered solid foundation, an emulsified foundation and an oily foundation.
Conventionally, when producing a powdered solid foundation, various kinds of powders have been mixed and kneaded to prepare a skin-colored foundation composition, and the composition has been filled in a dish.

On the other hand, in order to make the appearance of the cosmetic itself attractive, a powder solid foundation is formed by multicolor filling (for example, see Patent Document 1).
In addition, since the selection of the application color is very important especially in the foundation, a multicolor filling foundation in which the appearance color of the main part and the expected application color are substantially the same has been proposed, and a plurality of filling compositions have been proposed. There has been disclosed a foundation in which the chromaticity difference between appearance colors is equal to or less than a certain value (for example, see Patent Document 2).

  As described in Patent Document 2, in a foundation, selection of a coating color is very important. For this reason, despite the above proposals, foundations that still exhibit flesh color are the mainstream.

JP-A-2002-154930 JP 2014-005262 A

  Certainly, a foundation exhibiting a flesh color is advantageous from the viewpoint of selection of a coating color.However, the present inventors have studied and found that a foundation exhibiting a flesh color has lost the original vividness of a pigment. did. In other words, foundations that exhibit flesh color create a flesh color by mechanically mixing and kneading multicolor pigments, but when pigments are mixed, they have the property of absorbing each other's wavelength range. A phenomenon called subtractive color mixing occurs in which the colors overlap to darken.

Although the problem of the subtractive color mixture was thought to be solved by using a multicolor filling foundation, the present inventors conducted repeated studies and found that in the multicolor filling foundation, a puff was slid to mix multiple colors. At that time, they conceived that there was also a problem that the same skin color was exhibited, that is, it was difficult to maintain the required coating color. Such a problem is not considered at all in the above patent document.
An object of the present invention is to provide a makeup cosmetic, particularly a foundation, which can simultaneously solve the above two problems.

The present inventors have conducted research to solve the above-mentioned problems.When the puff is slid and the multicolor powdered solid cosmetic is scraped, irregularities are generated on the surface of the solid cosmetic as it is used. It was conceived to make it difficult to exhibit the same flesh color due to the variation in the amount of removal. Then, they have found that the above two problems can be solved simultaneously by adjusting the hardness of each color constituting the multicolor powder solid cosmetic.

The present invention is a multicolor powdered solid cosmetic, in which a plurality of colored solid compositions are arranged with regularity or at random in a planar direction,
In a test of rubbing the surface of a multicolor powdered solid cosmetic with a load of 2.9 N using a cosmetic puff made of NBR (nitrile rubber), the chromaticity of the cosmetic rubbed for the first time and the cosmetic rubbed for the 300th time Is a multicolor powdered solid cosmetic having a chromaticity difference ΔE with the chromaticity of 2.0 or less.
In addition, the plurality of colored solid compositions is preferably in a form containing red, red yellow, and / or yellow in the Munsell color system, including black powder, and in the Munsell color system, red, red yellow, The and / or yellow colored solid composition preferably has a form substantially not containing black powder.
In addition, the plurality of colored solid compositions preferably include blue, blue-green, and / or green in the Munsell color system, and preferably include blue, blue-green, and / or green colored solids in the Munsell color system. The composition preferably includes a black powder.
Further, a form containing at least 1 to 15% by mass of the pigmented titanium oxide based on the total amount of the multicolor powder solid cosmetic is preferable, and the difference between the maximum value and the minimum value of the hardness of the plurality of colored solid compositions measured with a rheometer is A form of 160 or less is preferable, and the plurality of colored solid compositions of the same shape are regularly arranged, or at least a part of the plurality of colored solid compositions arranged in a marble shape at least in part thereof. Is preferred.
