Description

  The present invention relates to a powder cosmetic suitable for use in retouching makeup.

  Make-up cosmetics, especially foundations such as foundations, are required to have effects that correct skin problems such as spots and dullness and produce various finishes, while maintaining the effects for a long time. It is also demanded that the makeup does not collapse and the makeup lasting is good. In order to meet such demands, attempts have been made to include in makeup cosmetics materials that improve makeup retention. For example, an attempt has been made to improve the longevity of cosmetics by adding a powder surface-treated with a perfluoroalkylalkoxysilane compound to cosmetics and imparting water and oil repellency to the cosmetics (see, for example, Patent Document 1). ). However, even with such a technique, when makeup is applied to the skin for a long time, makeup collapse occurred and the makeup effect was not sufficient.

In order to solve such problems, a method has been used in which makeup loss is corrected with a makeup retouching cosmetic every time makeup makeup occurs after applying makeup to the skin. In particular, for ease of use, powder cosmetics have been frequently used for these cosmetics. Is the functions required for face lift powder cosmetics, cosmetics spreadability on the skin, the better the so-called elongation, it has high affinity with the skin is obtained. In order to meet these demands, attempts are made to improve the spread using talc with a specific average particle size and particle size distribution (see, for example, Patent Document 2), and the surface of talc, sericite, mica, etc. is treated with metal soap. However, attempts have been made to lower the average friction coefficient of the powder, improve the slipperiness of the cosmetic, and improve the spread (for example, see Patent Document 3).

However, in these attempts, since the compatibility with the skin is insufficient and the slipping property between powders is insufficient, it is applied on the skin where makeup breakup has occurred and the makeup has been applied once. In such a case, there is a problem that the effect of re-dressing is insufficient, and there has been a demand for a powder cosmetic that can provide a sufficient re-dressing effect even when applied on the skin where makeup remains.
On the other hand, a powder having a sufficient retouching effect even if it is applied on the skin where makeup remains by reducing the average coefficient of friction of talc and incorporating it in a retouching powder cosmetic, regardless of the surface treatment. It has never been known that cosmetics can be obtained.

  It is an object of the present invention to provide a powder cosmetic that can be applied evenly on the skin where makeup has been lost and has an excellent retouching effect.

In view of such a situation, the present inventors conducted extensive research on the relationship between the physical properties of various talc and the re-dressing effect of the powder cosmetic for re-dressing containing the talc. The powder cosmetic containing talc is uniformly applied on the skin where makeup has been lost, has an excellent retouching effect, and further contains a plate-like powder coated with a polymer having a phosphorylcholine group. The inventors have found that the effect is promoted and have reached the present invention. That is, the present invention is as follows.
1) A powder cosmetic for retouching, containing talc having an average coefficient of friction (MIU) of 0.30 or less.
2) The powder cosmetic for retouching according to 1), wherein the content of talc having an average coefficient of friction (MIU) of 0.30 or less is 20 to 50% by mass relative to the total amount of the cosmetic.
3) The powder cosmetic for retouching according to 1) or 2), further comprising a plate-like powder coated with a polymer having a phosphorylcholine group.
4) The powder cosmetic for retouching according to any one of 1) to 3), which is loose.

It is possible to provide a powder cosmetic that can be applied evenly on the skin where makeup has been lost and has an excellent retouching effect.

It is the figure which showed the application | coating state of the loose powder of Example 5 in Test Example 2. FIG. 6 is a diagram showing a loose powder application state of Comparative Example 4 in Test Example 2. FIG. 6 is a view showing a loose powder application state of Comparative Example 5 in Test Example 2. FIG.

(1) Talc with an average friction coefficient of 0.30 or less of the present invention The powder cosmetic of the present invention contains talc with an average friction coefficient (MIU) of 0.30 or less as an essential component as an essential component. . Here, the average friction coefficient is measured by the following method.

A measurement sample was obtained by uniformly applying the measurement powder on artificial leather with a finger so as to be 1 mg / cm ^2, and measured with a Kato Tech friction tester KES-SE under a load of 50 g.

  The talc having an average coefficient of friction (MIU) of 0.30 or less according to the present invention is, for example, formed into a slurry by dispersing talc in water at a high concentration, and by applying a strong mechanical force to the slurry, the shape of the talc surface is changed. It can be manufactured by a method such as a smooth finish. Further, since there are commercially available products, it is also possible to obtain and use these commercially available products. Specific examples of such commercially available products include “Talc EX-15” (manufactured by Yamaguchi Mica).

  The content of talc having an average coefficient of friction (MIU) of 0.30 or less in the powder cosmetic of the present invention is preferably 20 to 50% by mass, and preferably 30 to 40% by mass with respect to the total amount of the powder cosmetic. Is more preferable. If the content is too small, it is difficult to uniformly apply the powder cosmetic on the skin, and the retouching effect may not be sufficiently exhibited, which is not preferable. On the other hand, when the content is too large, the adhesion to the skin is lowered, and the finish of the powder cosmetic may become powdery, which is not preferable.

<Manufacture example 1> Manufacture example of talc whose average friction coefficient (MIU) is 0.30 or less 300 g of talc (Talcan powder PK, Hayashi Kasei Co., Ltd .; average friction coefficient 0.36 measured by the above method) was added to 700 g of water. A talc slurry was prepared by uniformly dispersing at 2000 rpm using a disper. Further, this slurry was treated at 7000 rpm for 30 minutes using a disper, and then treated talc 1 was obtained through filtration and drying steps. The average friction coefficient of the treated talc 1 was measured by the above-described method and found to be 0.28.

(2) A plate-like powder coated with the polymer having a phosphorylcholine group of the present invention.
Since the powder cosmetic of the present invention improves the affinity between the powder cosmetic and the skin, the powder cosmetic preferably further contains a plate-like powder coated with a polymer having a phosphorylcholine group. As a polymer having a phosphorylcholine group used for coating, for example, a phosphorylcholine group together with a group such as an alkyl group on a polymer substrate usually used in cosmetics such as a polyacrylic acid structure and a polymethacrylic acid structure, directly or via a spacer Mention may be made of bound polymers. Specific examples of such a polymer include poly-2-methacryloyloxyethyl phosphorylcholine, 2-methacryloyloxyethyl phosphorylcholine / butyl methacrylate copolymer, 2-methacryloyloxyethyl phosphorylcholine / butyl methacrylate / methacrylic acid copolymer, 2-methacryloyloxyethyl. Examples include phosphorylcholine / stearyl methacrylate copolymer.

  Such a polymer can be obtained by polymerizing a monomer having a corresponding structure by a conventional method, but since there are many commercially available products, such commercially available products can be obtained and used. Specific examples of commercially available products include “Lipidure HM”, “Lipidure PMB”, “Lipidure A”, “Lipidure S”, and “Lipidure NR” (all manufactured by NOF Corporation).

  Specific examples of the plate-like powder as the base for coating the polymer described above include talc, mica, sericite, titanium mica, boron nitride and the like. Of these, talc and sericite are particularly preferred.

  The coating amount of the polymer having a phosphorylcholine group on the base powder is preferably 0.01 to 5% by mass, more preferably 0.05 to 2% by mass in the coated powder. When the coating amount is too small, the powder cosmetic containing the powder is not preferable because it may not be applied uniformly on the skin due to insufficient feeling of adhesion to the skin. On the other hand, when the amount is too large, the powder cosmetic containing the powder aggregates due to the aggregation of the coated powders, which may not be applied uniformly on the skin.

  The plate-like powder coated with the polymer having a phosphorylcholine group of the present invention is obtained, for example, by dissolving the above-described polymer in a solvent such as water, mixing the plate-like powder serving as a substrate, and stirring the mixture. However, since it can be produced by a method in which the solvent is volatilized, since there are commercially available products, such commercially available products can be obtained and used. Specific examples of such commercially available products include “Lipidure Talc” (manufactured by NOF Corporation: 2-methacryloyloxyethyl phosphorylcholine / stearyl methacrylate copolymer 0.1% by mass coated with 99.9% by mass of talc). It can be illustrated.

  The content of the plate-like powder coated with the polymer having a phosphorylcholine group in the powder cosmetic of the present invention is preferably 1 to 20% by mass, and more preferably 5 to 15% by mass. When the content is too small, the powder cosmetic containing the powder lacks the feeling of close contact with the skin, and may not be uniformly applied on the skin, which is not preferable. On the other hand, when the amount is too large, the powder cosmetic containing the powder aggregates due to the aggregation of the coated powders, which may not be applied uniformly on the skin.

<Production Example 2> Production Example of Plate-shaped Powder Coated with Polymer Having Phosphorylcholine Group 0.2 g of poly-2-methacryloyloxyethyl phosphorylcholine was dissolved in 500 ml of water to obtain a uniform aqueous solution. Sericite ("Sericite FSE" manufactured by Sanshin Mining Co., Ltd.)
99.8g was added and it stirred on 2000 rpm conditions using the disper, and obtained the uniform dispersion | distribution slurry. The slurry was dried at 105 ° C. for 48 hours to obtain polymer-treated sericite 1.
