Description

  The present invention relates to a makeup cosmetic, and more particularly to a makeup cosmetic that maintains the optical effect of pearly luster powder.

  In cosmetics, makeup cosmetics have the effect of covering unsatisfactory pigments such as skin spots and freckles and making them inconspicuous due to their optical effects. Such an effect depends on the optical effect of the contained color material, but if the optical effect of the color material changes, the make-up function will naturally change, which is very different from the situation where the use is started. For this reason, the makeup function itself is often impaired, and such a phenomenon is recognized as the quality of makeup collapse. The reason why the optical effect of such a color material changes with time is mainly due to a change in the physical presence state of the color material. For example, the spectral value is changed by wetting, and the alignment of the flat powder is changed and the cooperation of the optical effect is impaired. With regard to the removal from the skin, the inclusion of adhesive materials such as silicone elastomers and acrylic polymer emulsions can prevent the removal and improve the longevity of the makeup (see, for example, Patent Document 1 and Patent Document 2). It is known that the durability of cosmetics can be improved by hydrophobizing treatments such as hydrogen methylpolysiloxane baking treatment and perfluoroalkylsilane treatment for changes in optical effects due to material wetting. (For example, see Patent Document 3 and Patent Document 4). In addition, by applying additive color mixture and relying on the optical effect of makeup cosmetics only on the combination of interference color materials, it is possible to significantly suppress the color material from becoming dull due to sebum wettability (for example, Patent Documents). 5).

  However, these methods are all closely related to cosmetic dosage forms, and in the emulsification system, only the improvement of adhesion using an acrylic polymer emulsion is used. There was no current situation. If surface treatment is performed, the dispersibility in the emulsification system may be impaired, and the additive color mixture is an additive color mixture material. The dispersion orientation of the interference light pearl may not be obtained in the emulsion system. This is because there are not many. That is, here, in order to realize additive color mixing in the emulsification system, in the emulsifier form containing the interference light pearl powder, the technology for uniformizing the orientation during dispersion of the interference light pearl powder. It can be said that development was desired.

On the other hand, it is an emulsified cosmetic containing 1 to 20% by mass of interference light pearly luster powder having a particle size of 50 μm to 200 μm, and containing one or more core-shell type acrylic polymer emulsions. No makeup cosmetics are known, and it is not known at all that makeup cosmetics employing such a configuration maintain the original optical effect for a long time and exhibit an excellent makeup-holding effect. .

It is an object of the present invention to provide a technique for uniforming the orientation in time.

In view of such a situation, the present inventors, in order to achieve additive color mixing in the emulsification system, in the emulsifier form containing the interference light pearl powder, when the interference light pearl powder is dispersed. As a result of earnest research efforts to find the technology to make the orientation uniform in this way, we found that such additive color mixing is possible in emulsification using a core-shell type acrylic polymer emulsion.

  According to the present invention, it is possible to provide a technique for making the orientation uniform when dispersing the interference light pearl powder in the emulsifier form containing the interference light pearl powder.

(1) Interference light pearly luster powder which is an essential component of the makeup cosmetic of the present invention The makeup cosmetic of the present invention comprises 1% by mass to 20% by mass of interference light pearly luster powder as an essential component. Preferably, 3 to 10% by mass is contained. Further, the preferable particle diameter of the interference light pearl luster powder is a particle diameter measured with a Coulter counter, and is preferably 50 μm to 200 μm. If this is too small, the effect of the interference light may not be sufficient. In such a case, it may be difficult to perform color mixing by additive color mixing. If it is too large, the dispersion in the emulsified system may occur. This is because stability may be lost and sedimentation may occur. Here, the interference light pearly luster powder is a general term for powders in which a metal oxide is coated on a flake powder and emits an interference color by a diffraction grating formed by the metal oxide. Examples of the powder powder include mica, sericite, glass flake, borosilicate glass and the like, and examples of the metal oxide to be coated on these surfaces include zinc oxide and titanium dioxide. . If desired, a spacer such as zirconium oxide, alumina, or anhydrous silicic acid can be interposed in the metal oxide.

In addition to this, titanium mica that expresses interference light can also be used. As such titanium mica, “Flamenco Series (registered trademark)” of BASF can be suitably exemplified, and specifically, flamenco (registered trademark). SP100, Flamenco (registered trademark) Satin 100, Flamenco (registered trademark) Red 100, Flamenco (registered trademark) Gold, Flamenco (registered trademark) TX-EYF, Flamenco (registered trademark) Green, and the like can be suitably exemplified. These can contain only the seed | species, and can also be made to contain in combination of 2 or more type. In the makeup cosmetic of the present invention, since it is used as an additive color mixture, it is preferable to contain at least two colored interference light pearly luster powders.

In such a case, the ratio of the white interference light pearly luster powder to the total amount of the interference light pearly luster powder is preferably 10 to 30% by mass, and more preferably 15 to 25% by mass. This is because if the content is too small, it is difficult to adjust the brightness range, and if it is too much, it is difficult to adjust the color.

These can contain only the seed | species, and can also be made to contain in combination of 2 or more type. When such a water-insoluble polymer is used in the makeup cosmetic of the present invention, the content is preferably 1 to 30% by mass, more preferably 1% to 30% by mass in terms of the resin content relative to the total amount of the cosmetic. 5 to 20% by mass. In such a content, such a component has the effect of dispersing the interference light pearly luster powder in an orientation in which the directionality is adjusted and the interference color easily develops. In addition, as a secondary effect, it also has an effect of improving the adhesion of a decorative film formed on the skin.

Can be illustrated. Also, it is preferable to disperse the interference light pearly luster powder in the outermost phase in order to adjust the orientation of each powder. In addition, since it is an emulsifier type, it contains a surfactant for emulsification, but as such a surfactant, one that does not interfere with the dispersion orientation of the interference light pearl is preferable.
