DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation cosmetic for adjusting the condition of the skin to be used before applying a makeup such as a foundation.

More specifically, by blending a mica-titanium-based pigment substantially free of interference colors colored with low-order titanium oxide, the finish applied on the foundation is shaded to give a three-dimensional effect. Also, the present invention relates to a base cosmetic having an excellent effect of clearly showing a face line, a nose line, and the like.

[0003]

2. Description of the Prior Art When applying makeup cosmetics such as foundations, base cosmetics are used to adjust the condition of the skin and improve the adhesion, spread and finish of the cosmetics. As the types of base cosmetics, emulsifying types that give a moist feeling and lotion types that give a refreshing feeling are commercially available.

[0004] Base cosmetics are further classified into three groups according to the purpose of the user. One is the use of creams, emulsions or lotions for the purpose of improving the foundation and spreading of the foundation. In this case, the amount of the applied foundation differs depending on the type used. That is, when applying creams, the amount of foundation applied becomes large, and when applying lotions, the amount of foundation applied becomes small.

[0005] The second is a case where the emulsion or lotion is used for coloring to finely control the skin color. This is a base cosmetic that is colored green or pink using colored pigments. The green base makeup is applied when the skin color is red to suppress redness. The pink base cosmetic is used when the skin color is dull or when the complexion is poor during menstruation, and controls the skin color to a healthy skin color. By using the foundation from above, the original beauty of the foundation can be brought out.

A third object is to use the composition as a base cosmetic having an ultraviolet protection effect. This is obtained by adding a UV absorber and a UV scattering agent to the base cosmetic.
However, in order to increase the UV protection effect, it is necessary to increase the amount of fine particle titanium oxide as a UV agent or the amount of powder such as titanium dioxide covering the skin. This has a very excellent UV-cut effect, but tends to look whitish and unnatural.

As described above, the base cosmetics can be used to (1) improve the foundation of the foundation, (2) control the skin color to make it a uniform skin color, and make the foundation take advantage of the finish, (3) It has been used for the purpose of increasing the UV effect by being used in combination with a foundation.

[0008] However, in order to respond to the needs of consumers that change with the times, the development of new foundation cosmetics is urgently needed. Therefore, the development of new foundation cosmetics that do not belong to the above classifications has been intensively studied. Have been.

[0009]

Problems of the Prior Art Under such circumstances, conventionally, a method of changing the texture of a face by makeup to give a three-dimensional effect is a well-known method in which foundations with different brightness are used. Applying to different parts of the face and shading it to make the face line look clear, or a method such as nose shadow etc. to put a black-brown shadow on a specific part of the face and make the nose muscles etc. clear is there. However, these methods require a long time for make-up because some makeup products must be used together, and because they use different color tones, the boundaries are noticeable and do not use advanced techniques And the finish was unnatural.

An object the present inventors of the invention has been made in view of the above circumstances, a result of intensive studies, the underlying cosmetics titanium mica pigment having no interference color colored with substantially lower titanium oxide If you mix
A subtle change in the texture of the finish, such as the foundation applied, gives a three-dimensional effect by shading the finished skin, and provides a base cosmetic that has an excellent effect of clearly showing face lines, nose streaks, etc. And completed the present invention.

[0011]

That is, the present invention relates to a base cosmetic comprising a mica titanium-based pigment substantially free of interference colors, which is colored with low titanium oxide. Hereinafter, the configuration of the present invention will be described. The mica constituting the mica titanium-based pigment substantially free of interference colors colored with lower titanium oxide, which is blended in the base cosmetic of the present invention, may be of any kind, and is not particularly limited, Generally, the particle size of mica is about 1 to 50 μm, and among these, particles having a shape as flat as possible are preferable. For example, commercially available muscovite (muscovitemica)
And, in some cases, biotite titanium-based pigments.

[0012] lower titanium oxide of the present invention described generally obtained by reducing a titanium dioxide, the general formula Ti _n O _{2 n-1}
It is represented by Several methods are known for the synthesis of low order titanium oxide. For example, (1) metal titanium and titanium dioxide are mixed at various composition ratios, and the mixture is heated at 900 ° C. to 1200 ° C. in vacuum. Firing and reducing,
(2) Titanium dioxide in an ammonia stream at 600 ° C. to 1
Heated at 000 ° C. to form black titanium oxynitride (TiO 2)
(N)), (3) 100 parts of titanium dioxide
There is a method of reducing with hydrogen gas at a high temperature of not less than ℃.

The color tone of the lower titanium oxide used for producing the titanium mica pigment of the present invention slightly changes depending on the structural formula and crystal type. Examples are shown in Table 1.

[0014]

[Table 1]

The titanium mica-based pigment of the present invention is a pigment in which the surface of mica particles is coated with titanium dioxide and low titanium oxide, or low titanium oxide. There is no.

Some examples are as follows: (1) Commercially available titanium-based mica pigments are reduced at a temperature of 500 ° C. to 1000 ° C., preferably 700 ° C. to 900 ° C., to reduce the reducing power of hydrogen gas and ammonia gas. A method of heating and reducing with one or more of these gases, or with a mixed gas of a gas having these reducing powers and an inert gas such as helium gas, argon gas, or nitrogen gas; (2) commercially available mica titanium pigments (3) mixing titanium metal with commercially available mica titanium-based pigment, and mixing the mixture under vacuum at 500 ° C. to 1000 ° C., preferably 700 ° C. ~ 900 ° C
And heat reduction. Further, an aqueous solution of an inorganic acid salt of titanium (for example, titanyl sulfate) as disclosed in JP-B-43-25644 is hydrolyzed in the presence of mica to precipitate hydrous titanium dioxide on the surface of mica particles. From 500 ° C to 1000 ° C,
Preferably, at a temperature of 700 ° C. to 900 ° C., one or two or more gases having reducing power such as hydrogen gas and ammonia gas, or a gas having such reducing power and a gas such as helium gas, argon gas, nitrogen gas, etc. By heating and reducing with a mixed gas with an active gas, or by precipitating hydrated titanium dioxide on the surface of mica particles and then heating to form titanium mica, this is reduced in the same manner as the above commercially available titanium mica pigment. Is also good. Further, the method of reduction is not limited to the method using a reducing gas such as the above-described hydrogen gas or ammonia gas, a method of reducing mica titanium using a reducing flame such as hydrogen, a mica titanium salt,
For example, a method of suspending in a titanium tetrachloride solution and oxidatively decomposing the suspension in a flame of a mixed gas of air and hydrogen may be employed.

The amounts of titanium dioxide and lower titanium oxide or lower titanium oxide that coat the mica can be varied over a wide range. The mica titanium-based pigment of the present invention is of a type having substantially no interference color.
It is preferable that titanium dioxide is coated in the range of 0 to 50 parts by weight and low order titanium oxide is coated in the range of 0.01 to 50 parts by weight based on parts by weight. When the amount of the low order titanium oxide is less than 0.01 part by weight based on 100 parts by weight of mica, the mica titanium obtained by the reduction according to the method of the present invention has no gloss, and A certain three-dimensional effect cannot be given. On the other hand, if it exceeds 50 parts by weight, an interference color tends to easily appear, and the mica titanium-based pigment obtained by reduction by the method of the present invention becomes a chromatic color, and the effect of the present invention cannot be obtained. This property is the same when the amount of titanium dioxide exceeds 50 parts by weight with respect to 100 parts by weight of mica.

The mica titanium pigment having substantially no interference color, which is colored with substantially lower titanium oxide, used in the present invention is as follows:
It may be subjected to a hydrophobic treatment. Examples of hydrophobizing agents include silicones, higher fatty acids, higher alcohols,
Examples thereof include fatty acid esters, metal soaps, amino acids, and alkyl phosphates, and other treatment methods may be used.

The amount of the titanium-based mica pigment substantially free of interference color, which is colored with lower titanium oxide, is 0.5% by weight to 10% by weight based on the total amount of the base cosmetic composition of the present invention.
Is preferred. More preferably, it is 1% by weight to 7% by weight. If the content is less than 0.5% by weight, the finish of the foundation and the like is shaded, giving a three-dimensional effect, and the effect of making the face lines and the nose muscles look clear is not exhibited. If the content is more than 10% by weight, the gloss becomes strong and the finish becomes glaring. Looks unnatural.

The production method is as follows: (1) The aqueous phase is heated to 70 to 80 ° C. and treated with a homomixer. (2) Add the powder to (1), perform homomixer treatment again,
Add potassium hydroxide and stir. (3) The oil phase is heated and dissolved at 70 to 80 ° C, and a fragrance and a preservative are added. (4) Add (3) to (2), emulsify with a homomixer, and degas. (5) Cool to 30 ° C. The following powdery foundation was applied over the base cosmetic.

[0048]

[Table 5]

As the production method: (1) The powder part is mixed with stirring. (2) Dissolve the oil, preservative, and fragrance and spray on (1). (3) Pulverize and mold (2) to obtain powdery FD.

In this manner, a foundation cosmetic (with and without the mica titanium pigment described in the present invention) and a powdery foundation can be obtained. Sample preparation method: (1) Doctor plate (0.35mm) on matte black paper
A base cosmetic film having a certain thickness is prepared using the above method, and left overnight to remove moisture to obtain a sample. (2) A powdery foundation sample is obtained by applying a powdery foundation to a transparent cellophane tape with a sponge, and then removing excess powder with a brush to obtain a uniform film. (3) The measurement is performed as a set of two sheets in a combination shown in Table 6.

[0051]

[Table 6]

As a measuring instrument, a Hitachi gloss meter C-1020 was used.

Table 7 shows the measurement results.

[0054]

[Table 7]

As can be seen from Table 7, as compared with Sample B, Sample A shows a higher reflection near 140 ° in the regular reflection direction and 45 ° in the regular reflection direction, and 9
Low values are shown near 0 ° to 100 ° and around 160 °. This is because the mica titanium-based pigment according to the present invention shows strong reflection (gloss) in the specular reflection direction, and in other directions, the color is black to gray, which is an achromatic color of the external color, so that the reflection is small. This is because the contrast effect is clear. Further, since the light was reflected from the lower surface of the foundation, when applied to the face, there was no unnaturalness such as a pearly feeling or a shining feeling on the applied surface.

When Sample A was applied to the face, the specular reflection direction appeared bright and the other directions appeared dark, so that the face was shaded and looked three-dimensional. In addition, it was excellent in the effect of clearly showing the face line, the nose line, and the like.

After the base cosmetics obtained in Examples 2 to 7 and Comparative Examples 2 to 3 to be described later were applied to the face by 20 panelists specializing in the actual use test ,
After applying the powdery foundation, a test was performed to determine the three-dimensional appearance of the face, whether the face line, nose line, etc. could be clearly seen. Table 8 shows the results. still,
The evaluation method in Table 8 was based on the following criteria.
