The present invention is characterized by blending irregularly shaped plate-like or spherical fine particle powder with high uniformity in particle size. The aim is to provide a cosmetic that gives a uniform, mild luster and translucent skin feel through use and excellent adhesion, and has a natural finish without leaving any thick spots. . Conventionally, there are various powders commonly used in cosmetics, but most of them are derived from natural minerals, and their particle sizes are generally irregular, making them difficult to use in actual cosmetics. What you have is
For example, the particle size is 1 to 40μ, and the average particle size is 5μ.
Particles with a wide range of particle diameters, such as ~20μ, and with a relatively large average particle diameter, have been frequently used. However, when cosmetics using such powders contain a large amount of powder with large particle diameters, the resulting cosmetics give a feeling of elasticity when applied to the skin, but feel heavy and grainy. It also has poor consistency and is thick. On the other hand, if the powder with a small particle size becomes large, the adhesion of the obtained cosmetic will improve when applied to the skin, but it will feel squeaky and slippery, and it will also become more whitish and powdery. It had drawbacks such as an unnatural finish. Since conventional powders are a mixture of a wide range of particle sizes, it has been difficult to overcome the above-mentioned drawbacks, and it has been impossible to obtain desirable cosmetics. Therefore, the inventor of the present invention has carried out various experimental studies in an attempt to solve the above-mentioned drawbacks and to obtain a new cosmetic that has a particularly mild feeling of use and a natural finish.
By blending fine particle powder with a specific shape with high uniformity in particle size, this drawback is eliminated.
In addition, we have found a cosmetic that has the desired cosmetic effect. The present invention is composed of an irregularly shaped plate-like powder or a spherical powder, and the powder has a particle size of 1 to 10μ, of which the ratio of 1 to 5μ is 50% by weight or more, and furthermore, the total average particle size is The present invention relates to a cosmetic composition characterized by containing one or more types of fine particle powder having a particle diameter of 2.5 to 5μ. The fine particle powder applied to the present invention is a powder having an irregular plate-like or spherical shape, and examples of inorganic powder include irregularly-shaped plate-like powders made of talc, sericite, synthetic mica, kaolin, bentonite, etc. Examples include powder, composite oxides such as magnesium silicate and calcium silicate, and hollow porous microspheres made of silica alone. Examples of the organic powder include spherical powder made of nylon powder, polyethylene powder, and the like. These powders have particularly excellent adhesion to the skin, and also have fluidity and smoothness of spread due to the shape of the powder, which is plate-like or spherical. In addition, the particle diameters of these fine particle powders are all 1 to 10μ, and 50% by weight or more of them are 1 to 10μ.
Particles with a particle size of ~5μ dominate, and the total average particle size is 2.5 to 5μ, preferably 2.5 to 3μ. If the particle size is smaller than 1μ, when used as a cosmetic, it will not feel slippery, and the makeup will have a white, powdery finish, lack transparency, and lose its skin feel. Moreover, if it exceeds 10μ, the roughness will be noticeable when used, it will not blend well with the skin, it will have poor adhesion, and the makeup will have a thick and flaky finish, which is undesirable. Here, a major feature of the present invention is to specify the particle size of the powder at the same time as specifying the shape of the powder. By using powder with so-called uniform grains, it not only solves the various drawbacks mentioned above, but also provides a mild feel (uniform softness to the touch) and a natural finish (many of its effects are due to the uniform softness of the touch). (originating from light scattering) can be obtained. Then, one or more types of fine particle powders are selected from the various types of fine particle powders mentioned above and blended into cosmetics, with a blending ratio of 0.5 to 95% by weight depending on the dosage form of the cosmetic.
It is blended within the range of. In addition, in the present invention, cosmetic raw materials other than the above-mentioned fine particle powders, such as powders and pigments having normal particle diameters, various oils represented by squalane, jojoba oil, cetanol, etc., surfactants, and moisturizers are used. agent,
Flavors and the like can be appropriately selected depending on the purpose of the product and can be used within a range that does not impair the effects of the present invention. In addition, there are a wide range of cosmetic formulations that can be applied to the present invention, including powder cosmetics such as face powder and pressed powder that are mainly composed of powder, oil-based cosmetics such as foundation, and even Examples include emulsified cosmetics such as creams. Evaluation Test 1 In order to confirm that the fine particle powder having a specific shape and specific particle size applied to the present invention is optimal for cosmetics, the present inventor has tested powders of thin plate shape, spherical shape, and other shapes (polygonal crystal shape, irregular shape, etc.). The results were the same for both regular and spindle-shaped powders.
3μ), less than 1μ, and more than 10μ in particle size were applied to the skin and tested for wearability, and a comparative evaluation was performed. The results are shown in Table-1.

[Table] As is clear from the results in Table 1, powders that are plate-like or spherical have good spreadability due to their shape, and do not feel rough or thick. In addition, when the particle size is 1 to 10μ, it spreads and provides an excellent cosmetic effect over all aspects including a natural finish and skin feel. Evaluation Test 2 Next, in order to confirm the effects of the obtained cosmetics of the present invention, the inventors tested various types of cosmetics shown in Examples 1 to 4 below and the corresponding commercial products (types of powder). The same products as in each example were used, but the particle size was wide and the average particle size was larger than the range of the present invention.) and a comparative product (in which the fine particle powder of each example was replaced with light calcium carbonate). (However, the particle size and average particle diameter are the same as those described in Cited Example 1.) A long-term continuous use test for 3 months was conducted by 100 women and a comparative evaluation was conducted. .
The results are shown in Table-2.
