Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cosmetics, and more particularly to improvements in the color tone observed when using cosmetics.

[0002]

2. Description of the Related Art In makeup cosmetics, it goes without saying that the color tone determines the value of the product. Recently, however, a pearl effect has been added to this, so that it plays a large role as a color effect in a comprehensive sense. It has become.

[0003] Conventionally, mica titanium, a natural fish scale foil, bismuth oxychloride, or the like, in which mica on a substrate or synthetic mica is coated with titanium oxide, has been used to impart gloss to a makeup cosmetic. The substances that produce these pearl effects are usually called pearl pigments or pearlescent pigments. Pearl gloss is due to multiple reflections with light interference and slight light scattering.
The subtle coloration and glossy finish have given the joy and satisfaction of those who use it in makeup products.

[0004] Among them, titanium mica can obtain red, blue, green and other luminescent colors relatively easily depending on the thickness of titanium dioxide coated on the mica surface, and is generally stable against heat, light and cosmetic ingredients. Therefore, it is widely used.

[0005]

However, although the conventional titanium mica has a glossy feeling, the chroma of the interference light is low, and there is a limit in giving higher makeup and fashionability. I couldn't respond to a strong request. In order to improve the color development, a method of blending a large amount of an organic dye or an inorganic coloring material was also employed. However, the color mixture was subtractive and the texture was completely different from that of light.

There are many products containing inorganic and organic spherical powders, but they are useful for improving the feeling of use such as smoothness during coating, but they do not improve the coloration and finish using interference light of the products. I couldn't improve. This is because the light scattering property of the spherical powder could not be used due to the low saturation of the interference light of the conventional mica titanium, and the coloration of the makeup product had not been promoted.

As described above, in the conventional makeup cosmetics, even if the interference light of mica titanium is used, the coloring and the finished feeling are insufficient when a higher effect is required, and are unsatisfactory.

[0008] The present invention has been made in view of the above problems, and provides a makeup cosmetic which enables a finish capable of observing a vivid color by unprecedented interference light from any angle. The purpose is to do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to attain the object of providing a cosmetic which enables a finish capable of observing a vivid color due to unprecedented interference light from any angle, an object of the present invention is to achieve the object. Et al. Have conducted intensive studies and have found that, instead of the low-chroma interference light represented by the conventionally used titanium mica, high-chroma powder with higher-chroma interference light and spherical light with light-scattering properties It has been found that the simultaneous use of a scattering powder and a synergistically high color saturation finish can be obtained from various angles, leading to the present invention.

[0013] Accordingly, the cosmetic of the present invention is a cosmetic containing a plurality of powders, wherein mica, synthetic mica, titanium oxide,
It is composed of one or more selected from silicon oxide, aluminum oxide, barium sulfate, bismuth oxychloride, glass, and zinc oxide, has an interference color, and has a flaky shape having an average particle diameter of 1 to 60 μm. When the measurement results obtained by the measurement method described below are expressed in the Munsell color system, (i) the saturation (C) when the hue (H) is in the P, RP, and R regions is 5.0. As described above, (ii) the saturation (C) when the hue (H) is in the YR and Y regions is 2.5 or more, and (iii) the saturation (C) when the hue (H) is in the GY, G and BG regions.

As described above, the present invention comprises a flaky high-saturation powder having a high-chroma interference light and a spherical light-scattering powder having a light-scattering property, so that they are optically related to each other. In addition, the light-scattering powder scatters the reflected interference light of the high-saturation powder, making it possible to see a highly saturated color tone from any angle while improving color development.

Here, the above conditions (i) to (i) for the high chroma powder

Set.

In the cosmetic according to the present invention, the saturation (C) thus determined is such that in the Munsell color system, the hue (H) of the coating film on the black base is P, RP, and the saturation (C) in the R region. Is 5.0 or more, preferably 5.3 or more, and the hue (H) is YR, and in the Y region, the saturation (C) is 2.5 or more, preferably 2.8 or more, and the hue (H) is GY, G,
In the BG region, the saturation (C) is 3.0 or more, preferably 3.
The hue (H) is B or more, and the saturation (C) is preferably 7.3 or more and preferably 7.5 or more in the PB region. If the saturation is lower than this, sufficient coloring cannot be performed, and even if the cosmetic is contained together with the light-scattering powder, the finish will not be vivid.

When measuring the hue and chroma of the high chroma powder, the reason for forming a coating film on a color matching paper on a black and white base and measuring the hue and chroma of the coating film formed on a black base Is to efficiently measure the color tone of the interference light generated in the high chroma powder. In the specification of the present application, the hue and chroma of the high chroma powder are measured with a CM1000 ^™ manufactured by Minolta Co., Ltd. as a colorimeter, and conditions are determined by using the measured values. I have.

As described above, in the cosmetic according to the present invention, the hue and chroma of the high chroma powder satisfying any of the conditions (i) to (iv) are mainly in a part of the incident light. It is preferable that the color component is recombined by giving a phase difference, a light component in a specific wavelength region is emphasized by interference to generate a colored light having a color tone different from that of the incident light, and the colored component is provided by the generated colored light. . This is because the hue and the saturation of the high-saturation powder are given by the colored light that is the interference light, so that when used together with the light-scattering powder, a synergistic coloring effect can be suitably exhibited.

In the cosmetic of the present invention, the flaky high chroma powder has an average particle diameter of 1 to 60 μm, preferably 5 to 30 μm. If it is 5 μm or less, the interference light is weak, and if it is 1 μm or less, almost no interference light is observed, and the synergistic coloring effect with the spherical powder is reduced. And 3
If it exceeds 0 μm, the specular reflection gloss such as glare gradually increases, and if it exceeds 60 μm, the specular reflection gloss such as glare becomes too strong, and the coloring effect seen at any angle due to the spherical powder. Is to be reduced.

In the cosmetic according to the present invention, the spherical light-scattering powder may be made of inorganic materials such as SiO ₂ and A.
Organic such as l ₂ O ₃ , which is composed of one or more of polyethylene, polymethyl methacrylate, polystyrene, nylon, cellulose, silicone, polyurethane and the like, and has an average particle diameter of 0.1 to 20 μm, preferably It is preferably from 5 to 10 μm.

When the average particle diameter is 5 μm or less, smoothness gradually decreases during use, and when the average particle diameter is 0.1 μm or less, the feeling of use deteriorates due to the lack of smoothness. On the other hand, when the thickness is 10 μm or more, the light scattering property gradually deteriorates, and when the thickness exceeds 20 μm, the feeling of use such as a rough feeling is slightly deteriorated.

The flaky high chroma powder having high chroma interference light used in the present invention preferably emits interference light when coated with metal oxide particles. Examples of the mother powder coated here include mica, synthetic fluorophlogopite, plate-like silica, plate-like alumina, plate-like barium sulfate,
Examples thereof include plate-like titanium oxide, bismuth oxychloride, and glass, and particularly preferred are mica, synthetic fluorophlogopite, plate-like silica, and plate-like alumina. Examples of the metal oxide include titanium oxide, zinc oxide, bismuth oxychloride, silica, alumina and the like, and one or more of these can be used in combination. Particularly, titanium oxide and silica are preferably used. preferable.

In the cosmetic of the present invention, the high chroma powder is selected from the group consisting of mica, synthetic mica, titanium oxide, silicon oxide, aluminum oxide, barium sulfate, bismuth oxychloride, and glass. A layered structure of three or more layers by coating any two or more of titanium oxide, zinc oxide, silicon oxide, aluminum oxide and bismuth oxychloride on the base powder by using one kind of flaky powder It is preferable that

By adopting such a multi-layered structure, multiple interferences can be generated with respect to the white light incident on the high chroma powder. Therefore, the color tone is adjusted by adjusting the thickness of each layer. It is possible to obtain interference light of high saturation.

Among the high chroma powders having a multilayered layer structure, flaky mica or synthetic mica is used as a mother powder, and a metal oxide is coated in the order of titanium oxide, silicon oxide and titanium oxide. It is suitable because it has the same usability as conventional titanium mica, stability against light, heat, and cosmetic components, and can obtain interference light with extremely high saturation.

The method of coating the mother powder with the metal oxide particles is not particularly limited, as long as it is performed according to a conventional method applied to the production of conventional titanium mica, such as coating titanium oxide on mica. good.

Hereinafter, the cosmetic of the present invention will be described in more detail with reference to examples.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic sectional view of a high chroma powder used in the cosmetic of the present invention. The high-saturation powder 2 shown in FIG. 1 has a synthetic mica 4 as a base powder, on which anatase-type titanium oxide 6 is coated, on which silicon oxide 8 is coated, and on which it is again applied. Anatase type titanium oxide 10 is coated. By forming the transparent materials having different refractive indices into a multi-layered layered structure, the incident light causes an optical path difference due to the layer thickness of each layer, causing multiple interferences, thereby generating very high chroma interference light. It is.

In particular, in conventional pearlescent pigments, mica titanium using anatase type titanium oxide has a lower interference light chroma than titanium mica using rutile type titanium oxide. By using the multilayer structure, it is possible to obtain interference light having high chroma despite using anatase-type titanium oxide.

In such a high chroma powder, the hue of the interference color obtained by adjusting the thickness of the titanium oxide layers 6 and 10 can be adjusted. To give some examples, when it is desired to generate interference light in which the hue (H) is in the P, RP, and R regions, the composition ratio of the powder is 30 to mica.
36%, silicon oxide 9-15%, titanium oxide 50-60

It is preferable that silicon oxide is 7 to 13% and titanium oxide is 57 to 67%. When it is desired to generate interference light having a hue (H) in a B or PB region, the composition ratio of the powder is mica. 26-32%, silicon oxide 7-13%, titanium oxide 5
Preferably, it is 6 to 66%.

The hue, saturation, and lightness were measured by the following test for each hue of interference light generated using such a powder, and the saturation was compared with the high saturation powder used in the present invention.

Table 5: Hue in the B and PB regions

As can be seen from Tables 2 to 5 and FIGS. 3 and 4, it can be seen that the high chroma powder used in the present invention has high chroma. In particular, as described in the test method, this test forms a coating film on a color matching paper on a black-and-white base using nitrocellulose containing powder as a sample, and measures the hue, lightness, and saturation of the coating on a black base. Measured with a color machine. The meaning of color measurement in the coating film on the black base is a method capable of efficiently measuring the hue, lightness, and saturation of the interference light generated in the pearlescent pigment. It has been shown that the body is capable of producing highly saturated interference light.

By mixing a high-saturation powder capable of generating interference light with high saturation and a light-scattering powder,
In the cosmetic of the present invention, for the incident light, the high-saturation powder generates high-saturation colored light by interference, and the light-scattering powder scatters the colored light over a wide range. Even from such an angle, it is possible to provide a cosmetic that can exhibit a vivid color tone due to interference light.

On the other hand, when a cosmetic is prepared using a powder that generates low-saturation interference light, such as Comparative Samples 1 to 3, when it is mixed with a light-scattering powder as in the present invention. In some cases, the interference light has a low saturation, the light scattering powder scatters the interference light, and the luminous intensity of the interference light decreases, resulting in poor color tone observed in cosmetics. If light scattering powder is not blended in order to mix the pearlescent pigment, the color tone due to interference light will be observable in the specular reflection direction with respect to the incident light, but in other directions In other words, the color tone due to the interference light cannot be observed, and the observed color tone varies depending on the observation angle.

As described above, according to the present invention, there is provided a high-saturation powder which generates interference light capable of observing a sufficiently beautiful saturation even if the interference light is scattered by the light-scattering powder and the luminosity drops. It has become possible to obtain it by mixing a light-scattering powder capable of scattering light.

Subsequently, the cosmetic of the present invention was actually prepared,
The characteristics were compared. The powdery foundation of the present invention was prepared based on the composition table shown in Table 6 below, and its properties were examined.

For comparison with the present invention, the hues shown in Table 4 were GY and G as pearl luster pigments conventionally used instead of the high chroma powders suitably used in the present invention as Comparative Example 1 for comparison. A foundation was prepared using Comparative Sample 2 which was in the BG region.

In Comparative Example 2, high chroma powder was used.
The foundation was made without using light scattering powder. Further, in Comparative Example 3, a pearl luster pigment conventionally used was used instead of the high chroma powder, and the hues shown in Table 4 were GY, G, B
A foundation was prepared using the comparative sample 2 in the G region without using any light-scattering powder. The amount of the powdery foundation prepared in this comparative test is shown below.

[0056]

[Table 6]

Example 1 formulated based on the above composition table
The practical properties of the powdery foundations of Comparative Examples 1 to 3 were evaluated. The evaluation method was carried out by actually using Example 1 and Comparative Examples 1 to 3 by 20 female panelists, vivid color development by interference light, appearance of color tone independent of angle, beautifulness of finish, gloss of finish. Were evaluated, and the responses were totaled. 17 or more respondents answered that they were good ◎, 12 to 16 respondents were good ○, 9 to 11 respondents were good △, 5 people ~
When 8 people answered that it was good, it was evaluated as x, and when the number of people who answered good was 4 or less, it was evaluated as xx. Table 7 shows the results.

[0058]

[Table 7]

The results of the comparative test were as shown in Table 7 above. Instead of the high chroma powder preferably used in the present invention,
Comparative Example 1 using Comparative Sample 2 in which the hues shown in Table 4 were in the GY, G, and BG regions as the conventionally used pearlescent pigment was used together with the light-scattering powder to obtain a color tone independent of the angle. It can be seen that although good results were obtained, the coloration due to the interference light was not sufficiently observed due to the low saturation of the interference light, and sufficient evaluation was not obtained. In addition, the lack of color development has led to a reduction in the gloss and finish of the finished product.

In Comparative Example 2 in which high-saturation powder was used but light-scattering powder was not used, light-scattering powder was obtained even though interference light with sufficient saturation was obtained by the high-saturation powder. As a result, the interference light is not scattered in multiple directions, so that the interference light is observed only in the specular reflection direction of the incident light, and the color tone changes significantly depending on the observation angle. As a result, the gloss of the finish cannot be evaluated sufficiently,
The cleanliness of the finish was bad.

Further, as pearlescent pigments conventionally used in place of the high chroma powder, the hues shown in Table 4 were GY,
In Comparative Example 3 using the comparative sample 2 in the G and BG regions, and further using no light-scattering powder, the chroma of the interference light of the pearlescent pigment was low, and there was no scattering action by the light-scattering powder. As a result, the appearance of the color tone depending on the angle also changed, and although the finishedness was fairly good, the beauty was remarkably inferior.

In contrast to these comparative examples, in Example 1, excellent evaluations were obtained in all items. This shows that the cosmetic of the present invention exerts a high effect by using a mixture of the high chroma powder and the light scattering powder.

From the above comparative test, it was found that a high effect can be obtained by mixing and using a high-chroma powder and a light-scattering powder which produce interference light having a high chroma of the present invention. Subsequently, it was examined whether the same effect can be obtained even with a high chroma powder that generates interference light having different hues.

In the above test, a high-saturation powder having a hue in the GY, G, and BG regions that generates interference light was used. The test was conducted using

The powdery foundation of the present invention was prepared on the basis of the formulation shown in Table 8 below, and its properties were examined. Further, for comparison with the present invention, the hues shown in Table 2 are P, RP, and R regions as pearl luster pigments which have been conventionally used instead of the high chroma powder preferably used in the present invention as Comparative Example 4 for comparison. The foundation was prepared using the comparative sample 2 which was in the above. The amount of the powdery foundation prepared in this comparative test is shown below.

[0066]

[Table 8]

Example 2 formulated based on the above composition table
And the practical characteristics of the powdery foundation of Comparative Example 4 were evaluated. The evaluation method was the same as that in the comparative test, in which 20 female panelists actually used Example 2 and Comparative Example 4 to obtain a vivid color by interference light, a color tone that did not depend on the angle, a beautiful finish, We asked them to evaluate the gloss of the finished product, aggregated the responses, and rated ◎ if 17 or more answered good, ○ if 12 to 16 answered good, and 9 to 11 good Answered △,
Five to eight respondents who answered that they were good were evaluated as ×, and the number of people who answered good was four or less was evaluated as XX. Table 9 shows the results.

[0068]

[Table 9]

The results of the comparative test were as shown in Table 9 above. Instead of the high chroma powder preferably used in the present invention,
Comparative Example 4 using the comparative sample 2 having the hue shown in Table 2 in the P, RP, and R regions as the conventionally used pearlescent pigment together with the light-scattering powder as in Comparative Example 2 in the above test. Although good results were obtained for the appearance of the color tone regardless of the angle by using it, it can be seen that the coloration due to the interference light was not sufficiently observed due to the low saturation of the interference light, and the evaluation was not sufficiently obtained. . In addition, the lack of color development has led to a reduction in the gloss and finish of the finished product.

On the other hand, in the second embodiment, a high-chroma powder which generates interference light in a hue region different from that of the first embodiment was used, so that the gloss of the finished product was somewhat less evaluated in relation to the skin color. However, excellent evaluations were obtained for all items. Thus, it was found that the cosmetic of the present invention does not impair the effect obtained by the hue of the high chroma powder used.

As described above, the present invention provides a cosmetic exhibiting a very excellent color tone by using both a high-saturation powder that generates interference light having high saturation and a light-scattering powder that scatters the interference light in multiple directions. Fees can be provided. It is preferable that the color tone of the interference light generated by the high-saturation powder to be mixed be appropriately selected depending on the color tone to be applied to the cosmetic. Hereinafter, some formulation examples of the cosmetic of the present invention are shown.
