Description

  The present invention relates to a makeup cosmetic containing a composite powder having a function of hiding sagging and creating a youthful impression.

  Conventionally, makeup cosmetics have functions to hide skin spots, freckles, uneven color, dullness, conspicuous pores, wrinkles, etc., to make the skin look beautiful and to change the texture. However, as we enter an aging society, in addition to these functions, the function of hiding facial and skin sagging with age, wrinkles, etc. and making it appear as a youthful face will be important in the coming years. Conceivable.

  Among these, it is important to give the face a three-dimensional effect in order to hide the slack and give a youthful impression. For that purpose, the face is divided into upper and lower parts, using a foundation with different color tones at the top and bottom, and applied so that the brightness of the makeup cosmetics on the top is higher than the one on the bottom, shading, and the face line is clean How to show (Patent Document 1), by applying a foundation cosmetic blended with a mica titanium pigment that does not have interference color colored with low-order titanium oxide, and then the foundation is overlaid, the face line and nose are clearly shown A method of increasing the three-dimensional effect (Patent Document 2), a method of blending a fine pearl pigment and a spherical resin powder into a foundation or a makeup base with an optimal amount and an optimal mixing ratio (Patent Document 3), and the like are shown.

  However, in the method of painting differently depending on the location of the face as in Patent Document 1, the delicate boundary of the cosmetic coating is concerned, and it is difficult to say that the finish is natural, and in the method of Patent Document 2, makeup cosmetics are not used. Because they are used in combination, make-up techniques are required, and it is difficult to create a lifted impression. Furthermore, in the method as disclosed in Patent Document 3, the regular reflection of the light of the pearl pigment and the diffuse reflection of the light of the spherical resin powder cancel each other's light characteristics and give a sufficiently youthful impression. There wasn't.

  Furthermore, a shadow appears due to sagging of the face from the nose to the lower part of the cheek around the mouth, and this shadow sagging is recognized, and it has the effect of a reflex board that makes this shadow disappear and looks rejuvenated The composite powder is also introduced in Patent Document 4.

  However, with the use of this composite powder, the brightness of the mother mica titanium is greatly reduced due to the composite, and the face shadow actually decreases, but conversely, the face seems to expand. It seemed to give a fat impression.

  Further, as for the wrinkles on the skin and the conspicuous pores, the gloss of the pearl pigment is made by a composite powder in which spherical fine particles of acrylic resin are coated on the flaky pearl pigment at a concentration of 40 to 60% by weight as in Patent Document 5. It is controlled to control the intensity of uniform diffuse reflection, but there is still the naturalness and transparency of the skin, but the light reflected from the face spreads and the face seems to be fat with a blurred impression It tends to look like, and it emphasizes the sagging of the skin.

  In view of the above situation, there has been a demand for the development of a makeup cosmetic that has a function of hiding facial aging, skin sagging, wrinkles, etc., and showing it on a face with a youthful impression.

JP-A-9-208428 Japanese Patent Laid-Open No. 5-43417 JP-A-2005-97218 JP 2003-342127 A Japanese Patent Laid-Open No. 9-48707

  Accordingly, an object of the present invention is to provide a cosmetic material having a makeup effect that makes the face lift up and show youthfulness.

In such a situation, the present inventors have conducted intensive research. As a result, spherical surfaces with a particle diameter of 200 to 400 nm are formed on the surface of a pearl pigment formed by forming a metal oxide coating layer containing titanium oxide on the surface of a flaky substrate. Complex powder coated with 2.0 to 10.0% by weight of the total amount of organic powder through any of the following steps is added to makeup cosmetics and applied to make the face easier. The present invention has been completed by finding that it looks lifted up and gives a youthful impression.
(1) A step of uniformly dispersing spherical organic powder together with a surfactant in water, adding a pearl pigment, further dispersing, adding a flocculant, filtering, washing, and drying.
(2) A step of uniformly dispersing a dispersion of an emulsion-like spherical organic powder in water, adding a pearl pigment, further dispersing, adding a small amount of a flocculant, filtering, washing, and drying .

  That is, it is a composite powder in which a spherical organic powder having a particle diameter corresponding to a wavelength shorter than or shorter than the wavelength range of visible light is coated with a concentration that allows an appropriate gap on the surface of the pearl pigment. If present, the reduction of the brightness of the pearl pigment due to the coating can be suppressed, and the regular reflection can be enhanced without diffusing light while maintaining the brightness. Furthermore, if this composite powder is used in makeup cosmetics, , While making the whole face brighter, the convex part of the face shines more, and the part around the face looks relatively low brightness and the face does not look swollen, but youthful impression I found out that

  In other words, the functions of the composite powder aimed at in the present invention are as follows: (1) The diffused light is eliminated, and the regular reflection is further enhanced, so that the light is produced on the convex portions of the face and lifted up. On the other hand, in order to suppress the noticeable wrinkles and pores, which are conventionally said to be shadows if the regular reflection is increased, the shadows should be covered with fine light. (2) The brightness of the entire face is not impaired by suppressing the decrease in brightness due to the combination of pearl pigments.

  In the present invention, the pearl pigment formed by forming a metal oxide coating layer mainly composed of titanium oxide on the surface of a flaky substrate has a particle diameter of 1 to 150 μm and a thickness of 5 μm or less, preferably 1 μm or less. It is a pearlescent pigment in which the surface of a flaky substrate such as mica, synthetic mica, or glass flake is uniformly coated with titanium oxide having a crystal form such as a rutile type or anatase type. In addition, the present invention includes those that change the thickness of the titanium oxide layer to be coated to give an interference color, that are coated with a part of titanium oxide replaced with iron oxide, or that are further coated with silicic anhydride. Pearl pigment.

This pearl pigment is a powder that emits strong luster and has an effect of making the face look brighter. However, a pearl pigment having a large particle diameter shines loosely on the skin, and the skin looks uneven and rough. Therefore, in order to make the skin look bright with a uniform coating film, a fine pearl pigment with a fine particle is preferable as the mother powder to be coated of the present invention, and the particle diameter of the pearl pigment is 60 μm or less. Among them, for example, as a commercial product, Ultima SB-100, Ultima SD-100, TIMRON STARLUSTER
MP-115, TIMIRON SUPERSHEEN MP-1001, TIMIRON SUPERSILK MP-1005, TIMIRON SUPER GOLD, TIMIRON SPLENDID GOLD, XIRONA VOLCANIC FIRE, TIMIRON FINE GOLD MP-20, COLORONA RED GOLD, COLORONA BRIGHT GOLD, TIMICA EXTRA BRIGHT, FLAMENCO SATIN PEARL , FLAMENCO ULTRA SILK, FLAMENCO SATANA, FLAMENCO VELVET, FLAMENCO ULTRA FINE, FLAMENCO PEARL, FLAMENCO SUPER PEARL, FLAMENCO GOLD, FLAMEN CO ORANGE, FLAMENCO SATIN GOLD, FLAMENCO SATIN ORANGE, FLAMENCO SUMMIT GOLD, CLOISONNE GOLD, CLOISONNE COPPER, CLOISONNE SATIN COPPER, CLOISONNE SATIN GOLD, CLOISONNE NU-ANTIQUE GOLD, DUOCROME YG, DUOCROME YR, there is such GEMTONE TAN OPAL, brightness The color tone is adjusted so as not to impair the color, and one or more of these pearl pigment series can be used.

  The spherical organic powder in the present invention is, for example, a spherical particle made of an organic natural product such as cellulose and an organic compound such as polyethylene, nylon, poly (meth) acrylate, polystyrene, or a methylsiloxane network polymer. Spherical polymer particles used as a raw material. In addition, the latter spherical powder by organic synthesis is a powder of a core shell structure in which a single polymer of these organic compounds or two or more kinds of copolymers, and further, different organic compounds are overlapped in two or more layers. is there. In the present invention, one or more of these spherical organic powders can be used.

  In the present invention, in order to make the convex part of the face brighter while brightening the entire face, the compounding of the powder is reversed without diffusing light while suppressing the decrease in the brightness of the pearl pigment due to the coating. Since the aim is to enhance regular reflection, the particle size of the spherical organic powder corresponds to a wavelength slightly shorter than the wavelength of visible light, in which light is not easily scattered or blocked, taking into consideration the average major axis of the pearl pigment used. 200 to 400 nm is used.

  The coating amount of the spherical organic powder in the present invention is 2.0 to 10.0% by weight in consideration of being able to change the reflection characteristics and not impairing the brightness of the pearl.

  In the present invention, a commercially available spherical organic powder can be used. However, in consideration of obtaining a desired particle diameter, a polystyrene-based resin, poly (meth) acrylic, which can easily control the particle diameter by emulsion polymerization or the like. It is better to use an acid ester-based resin, a copolymer of two or more of these, or a powder having a core-shell structure. In particular, polymethyl methacrylate, methyl methacrylate cross polymer, acrylates cross polymer, acrylates copolymer, (styrene / DVB) copolymer (DVB: divinylbenzene) can be easily controlled to various particle sizes, and can be used in powders and emulsions. There are many commercially available dispersions dispersed in water.

The manufacturing method of the composite powder which coat | covered the pearl pigment with spherical organic powder in this invention is as follows. (1) After dispersing spherical organic powder uniformly in water with a small amount of surfactant, a pearl pigment is added. A method of further dispersing and adding a small amount of an aggregating agent such as aluminum sulfate or polyaluminum chloride, filtering, washing and drying, (2) After uniformly dispersing the dispersion of emulsion-like spherical organic powder in water The pearl pigment is added and further dispersed, and a small amount of an aggregating agent such as aluminum sulfate or polyaluminum chloride is added, followed by filtration, washing, and drying .

  In order to impart water repellency and oil repellency, the obtained composite powder may be blended in cosmetics by performing various surface treatments such as metal soap treatment, silicone treatment, fluorine-containing compound treatment, and amino acid treatment. These treatments may be used alone or in combination of two or more.

  The present invention is a makeup cosmetic containing the above-mentioned composite powder. Specifically, makeup foundation, powder foundation, cream foundation, liquid foundation, oil-based solid foundation, emulsified solid foundation, face powder Cosmetics such as concealer, control color, teak color and eye shadow.

  Further, the amount of the composite powder to be blended into these makeup cosmetics is not particularly limited, but while brightening the entire face, the convex part of the face is more brilliant and the part around the face is relatively In order to obtain a youthful impression that is lifted up without the brightness appearing low and the face appearing to swell, 0.5 to 15.0% by weight is preferable. In particular, 1.0% by weight or more is good if the cheeks appear to be raised while being more consciously bright. When it mixes exceeding 15.0 weight%, there exists a tendency for gloss to be too strong and it may look like metallic skin.

  In addition to the composite powder described above, the cosmetics of the present invention include water, fats and oils, waxes, carbonized components that are blended in ordinary cosmetics as long as the effects of the present invention are not impaired as necessary. Hydrogen, fatty acid, alcohol, alkyl glyceryl ether, ester, silicone oil, fluorine oil, polyhydric alcohol, saccharide, polymer, surfactant, moisturizer, UV absorber, chelating agent, pH adjuster, antioxidant, metal Sequestering agents, bactericides / preservatives, dyes, fragrances, pigments, plasticizers, organic solvents, drugs, animal and plant extracts, pearl pigments, surface-treated powders, composite pigments, amino acids and peptides, vitamins, etc. However, the present invention is not limited to these.

  With the makeup cosmetics of the present invention, it is possible to obtain a youthful impression that brightens the entire face while making the convex part of the face brighter and lift up. Further, since the blended composite powder is a powder that suppresses diffused light and enhances regular reflection, this composite concept can be used in other fields as a technique for limiting the direction of light reflection.

Composite powder evaluation by gloss measurement While brightening the entire face, the convex part of the face is more shining, and the parts around the face appear to be relatively low in brightness, and the face does not appear to swell and lift up In order to realize a cosmetic that gives a youthful impression, the prepared composite powder was evaluated for light reflection characteristics by gloss measurement. First, a 40 mm width double-faced tape made by Nichiban was applied to the black portion of OPERITY CHARTS made by LENETA, and each powder sample was uniformly applied with a cosmetic cheek brush. The coated sample was fixed at an incident angle of 45 degrees with a digital variable angle gloss meter manufactured by Suga Test Instruments Co., Ltd., and the gloss intensity at each light receiving angle was measured.

  In general, micron-sized spherical powders and aggregates are said to diffuse light on the powder surface to hide wrinkles and pores from the skin. For example, when Mizupearl K-300 manufactured by Mizusawa Chemical Co., Ltd., which is a powder in which fine silica particles are aggregated, is measured by the above method, the angle dependence of the reflected light intensity is positive as shown in FIG. The graph changes in a hill-like shape with the reflection angle of 45 degrees as a vertex and a gentle skirt on the left and right. On the other hand, since the pearl pigment that easily gives the effect of three-dimensional effect has strong regular reflection, for example, as in the case of TIMIRON SUPERSHEEN MP-1001, the angle of regular reflection is 45 degrees and the peak reflection curve Indicates.

Actually, these two powders are blended into a makeup base with the following formulation (described as a powder to be examined during formulation) and applied to a doll for makeup training in half-face to prevent light from entering from outside. In an observation box surrounded by colored fabrics, observation was performed by illuminating at a certain distance with a D65 fluorescent lamp for color comparison / inspection from an angle of about 45 degrees to the left and right. The actual photograph is FIG. 2 and FIG. The right side of the face is applied with a makeup base containing the study powder, and the left side is applied with a makeup base prepared by replacing the study powder with purified water.

The water phase components (10) to (13) are mixed with stirring and heated to maintain 85 ° C. The components (1) to (9) of the oil phase part are mixed and dissolved by heating to 80 ° C. Then, after adding the above-mentioned water phase part to this oil phase part and pre-emulsifying, and emulsifying uniformly with a homomixer, the component (14)-(()) which dissolved the component (15), stopping a homomixer and continuing stirring. Add the mixture up to 17). Subsequently, cooling is started and component (18) is added at about 70 ° C., and further cooled to 35 ° C. to obtain a makeup base.

  Fig. 2 shows a makeup base formulated with Mizpearl K-300. When observed by five monitors, those who formulated Mizpearl K-300 on the right side of the five were reflected from the skin surface. The incoming light diffused and a so-called soft focus effect was felt, but on the other hand, it was evaluated that the face on the right side seemed to swell from the left side. On the other hand, the one containing TIMIRON SUPERSHEEN MP-1001 was applied with a makeup base containing MP-1001 as shown in FIG. Five monitors evaluated it as having a three-dimensional effect with contrast with the surrounding area.

  In the present invention, the three-dimensional effect is obtained like the TIMIRON SUPERSHEEN MP-1001 in FIG. 3, and the three-dimensional effect is further enhanced by compositing the powder from the pearl pigment such as the TIMIRON SUPERSHEEN MP-1001, that is, as described above. (1) By gathering light on the convex parts of the face by eliminating diffused light and increasing specular reflection relatively more, (2) To suppress the decrease in brightness due to the composite of pearl pigments We proceeded to study. For this purpose, the angle dependency of reflection is increased by compounding powder, that is, the intensity of light reflected from an angle deviating from 45 degrees that is regular reflection with respect to an incident angle of 45 degrees is relatively In other words, in the case of a composite powder that has a reflection curve with a skirted shape from the shape of a mountain-shaped reflection curve as shown in FIG. We thought that the contrast of the light in the out-of-range area was increased, and the three-dimensional effect could be emphasized and the effect could be produced as if it was lifted up. Therefore, in order to determine that the angle dependency of reflection has increased, the reflection intensity (I45) at a light receiving angle of 45 degrees and the reflection intensity (I65) at 65 degrees are measured in the same manner as the above-described gloss measurement method. And examined.

  Since the measured value cannot be expected when the specular reflection itself is greatly weakened by the coating, the spherical organic particles to be coated can be changed to the value of I45 before coating by changing the particle diameter and coating concentration. The value of I45 after coating was compared. The results are shown in Table 1. Table 1 summarizes the percentage of I45 after coating with respect to I45 before coating of each composite powder and the results of glossy impression. Glossy impression is determined by visual inspection of a sample for gloss measurement with 5 monitors, and 3 or more of them are judged to be “insufficient in gloss”. It was judged as ○.

  From this result, in order not to impair the intensity of the specularly reflected light, it was determined that the particle diameter from the finer to 400 nm and the coating concentration from low to 10.0% by weight were appropriate.

Furthermore, in order to determine the original three-dimensional effect, the ratio of I45 to I65, I45 / I65, is calculated, and I65 is relatively small with respect to I45. That is, I45 / I65 is the pearl pigment before being combined. Evaluation was made by using the value of the composite powder to be larger than the value. The results are shown in Table 2. In Table 2, this I45 / I65 value was determined as follows in comparison with the value of the original pearl pigment.
The I45 / I65 value is greater than 110% relative to the original pearl pigment value: A
I45 / I65 value is greater than 105% and less than 110% with respect to the original pearl pigment value: B
I45 / I65 value is greater than 100% and less than 105% of the original pearl pigment value: C
I45 / I65 value is less than 100% of the original pearl pigment value: D

  At the same time as the evaluation of the I45 / I65 value, a makeup base as a makeup cosmetic was prepared as follows in order to determine the effect when the composite powder was blended into the makeup cosmetic.

  The composite powder 1 was prepared as a comparative example 1 by preparing a makeup base as the component (17) examination powder in the makeup base formulation described above.

  The composite powder 2 was prepared as Example 1 by preparing a makeup base as the component (17) examination powder in the above-mentioned makeup base formulation.

The composite powder 14 was prepared as Example 6 by preparing a makeup base as the component (17) examination powder in the above-mentioned makeup base formulation.

The composite powder 15 was prepared as Example 7 by preparing a makeup base as the component (17) examination powder in the aforementioned makeup base formulation.

  In addition, a mixture obtained by simply mixing 1.25 g of methyl methacrylate crosspolymer having an average particle diameter of 300 nm and 48.75 g of pearl pigment (Merck Corporation TIMRON SUPERSHEEN MP-1001) used in the composite powder 2 was used. Ingredient (17) in the makeup base formulation: A makeup base was prepared as a comparative powder, and Comparative Example 3 was used.

  In Table 2, together with the results of the previous examination of I45 / I65 values, evaluation was performed by five monitors in the same way as when evaluating Mizpearl K-300 and TIMIRON SUPERSHEEN MP-1001 (to the right side toward the doll, Table 2 Apply the makeup base containing the composite powder listed in the above to the left side and apply the makeup base containing the original pearl pigment to the left). Good for the makeup cosmetics of Examples 1 to 10 and Comparative Examples 1 to 3 that were judged as good. The evaluation results are also shown.

From the results shown in Table 2, the makeup base containing the composite powder whose evaluations based on the I45 / I65 values are A to C is an evaluation of ◯ in which the three-dimensional effect appears to be lifted up. ing. And as shown in Examples 1 to 3 and Comparative Example 1, the particle diameter of the coating cannot be expected to be effective at 100 nm, and is determined in consideration of the decrease in the reflection intensity of I45. It can be seen that the particle size of is appropriate. Moreover, it can be judged that 2.0-10.0 weight% is suitable for the density | concentration to coat | cover from the evaluation of Comparative Example 2, Example 5 , and Reference Examples 1-3 .

  Furthermore, in Example 10, the reflection intensity was sufficient, the I45 / I65 values were good, and a three-dimensional evaluation could be obtained, but the particle diameter of the pearl pigment that is the base of the composite powder was large. Each particle on the skin surface shines with dots, and the texture of the skin looks rough. Therefore, it is considered that the particle diameter of the pearl pigment to be coated is preferably 60 μm or less from the results shown in Table 2.

  Further, from the results of Example 1 and Comparative Example 3, it can be determined that the three-dimensional effect and the lift-up feeling cannot be obtained from the original pearl pigment by simply mixing the pearl pigment and the spherical organic powder.

Next, in order to examine the compounding amount of the composite powder in the makeup cosmetics, the compound powder 14 is used to examine the component (17) of the above-mentioned makeup base prescription and change the prescription amount of the powder. did. The composite powder 14 containing 5.00% by weight is Example 6 described above.
