【００３３】
また、粉体をＮ−モノ長鎖脂肪族アシル塩基性アミノ酸で処理する方法としては乾式法及び湿式法のいずれの方法も用いることができる。乾式法は簡便かつ効果的であって、Ｎ−モノ長鎖脂肪族アシル塩基性アミノ酸の微細粉末を粉体と撹拌混合するか、もしくはＮ−モノ長鎖脂肪族アシル塩基性アミノ酸と粉体を混合した後、共粉砕することによって、粉体の表面を容易に処理できる。湿式法は、Ｎ−モノ長鎖脂肪族アシル塩基性アミノ酸が中性付近の水及び通常の油にほとんど溶解しないため、塩化カルシウムを可溶化剤として用いてＮ−モノ長鎖脂肪族アシル塩基性アミノ酸を有機溶剤に溶解した後、粉体を接触させ、更に水洗して塩化カルシウムを除去して乾燥することにより、粉体の表面を処理できる。あるいは酸性もしくはアルカリ性の水又は水性溶媒中にＮ−モノ長鎖脂肪族アシル塩基性アミノ酸を溶解して粉体を接触させた後、中性付近まで中和して粉体表面にＮ−モノ長鎖脂肪族アシル塩基性アミノ酸を析出付着させ、中和によって生じた塩を水洗により除去し、乾燥することによっても同様の表面処理ができる（特開昭６１−７２０２号公報、特開昭６１−１０５０３号公報）。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a cosmetic that can change the hue of the skin while giving a transparent feeling, has less noticeable pores, has a natural and bare skin feeling, and can obtain a very fine finish.
[0002]
[Prior art]
Conventionally, make-up cosmetics are applied to change the texture of the skin, so that a powder with strong diffuse reflection is mixed to obtain a matte finish, or a powder with strong specular reflection such as mica is mixed. I get a glossy finish. In addition, in order to cover the dullness of the skin due to poor blood circulation or aging (the skin becomes dark and yellow), pigments with high concealing power such as titanium oxide and iron oxide are blended. It has been practiced to change the hue of the skin by adding a red color such as.
[0003]
On the other hand, it is possible to change the skin hue sensation by using green pigment, which is a complementary color of red, to hide the red face and red acne scars, or by using blue or purple pigments to give transparency. Is being done.
[0004]
However, when a pigment having a high hiding power is used, there is a problem that an unnatural finish is caused without a transparent feeling. In addition, when the principle of complementary colors is used, hue can be covered, but saturation is reduced, and on the contrary, skin color becomes dull.
[0005]
Spherical composite powders are also used as light diffusing powders, but when these are blended, defects such as spots and freckles, wrinkles, dull skin, pores, etc. are covered and a matte finish is obtained, but fine It was difficult to obtain a cosmetic having both a function of covering pores and the like and a natural, transparent, and dull finish without obtaining a beautiful finish with a natural skin feeling.
[0006]
[Problems to be solved by the invention]
Therefore, an object of the present invention is to provide a cosmetic composition which does not change the color depending on the observation direction, can change the hue of the skin while giving a sense of transparency, has less noticeable pores, and can obtain a natural finish. It is in.
[0007]
[Means for Solving the Problems]
Under such circumstances, the present inventors have conducted intensive studies, and there is no transparency in the conventional makeup cosmetic and the skin color is dull because the hue control method is based on subtractive color mixing, The idea is that the more colors you add, the more the saturation decreases and the color approaches gray, and the principle of additive color mixing, that is, the color mixing using light, solves this problem. I thought I could. When the powder (A) having a specific color difference and the spherical composite powder (B) are used in combination, the hue of the skin can be changed while giving a transparent feeling, and the pores are not conspicuous and natural. The present inventors have found that a cosmetic having a bare skin feeling and a very fine finish can be obtained, and completed the present invention.
[0008]
That is, the present invention provides the following components (A) and (B)
(A): Mica surface coated with a mixture of titanium oxide and iron oxideOr further hydrophobizing the surfacePowder having an average particle size of 5 to 12 μm obtained by applying the powder on black synthetic leather at 8 mg / 100 cm.^TwoUniformly coated and measured at an incident angle of 45 °, a light receiving angle of −45 ° and −20 °, CIE1976L^*a^*b^*Two interference colors (L_45,45 ^* _,a_45,45 ^* _,b_45,45 ^*) And (L_45,20 ^* _,a_45,20 ^* _,b_45,20 ^*) For the following formula:
ΔE = [(L_45,45 ^*-L_45,20 ^*)^Two+ (A_45,45 ^*-A_45,20 ^*)^Two+ (B_45,45 ^*-B_45,20 ^*)^Two]^0.5

(B): One or two or more spherical composite powders selected from silicon oxide and a resin in which a powder of titanium oxide or zinc oxide is dispersed and zirconium oxide or aluminum oxide is supported on the surface. weight%
The present invention provides a cosmetic characterized by containing:
[0009]
Conventionally, pearl powder has been blended into foundations, etc., but in this case, the unique glossiness of the pearl causes a glaring feeling, resulting in a poor finish and an observation angle. The color tone may change due to the pearly feeling and interference. This is because in the conventionally used pearl powder, the interference color has directionality with respect to the incident angle of light, is strongly developed near regular reflection, and is hardly observable in other directions.
[0010]
On the other hand, the powder of the component (A) used in the present invention has a small change in color tone depending on the observation angle, that is, it can observe interference colors not only in the vicinity of specular reflection but also in a wide range. .
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
In order to determine the color difference (ΔE) of the powder of the component (A) used in the present invention, first, the powder was placed on black synthetic leather at 8 mg / 100 cm.²Using a sponge, lightly rub on synthetic leather and apply evenly. The color is measured at an incident light angle of 45 °, a light receiving angle of −45 °, and −20 ° using, for example, a goniospectrophotometer (GCMS-3, manufactured by Murakami Color Research Laboratory). The two interference colors at this time are represented by CIE1976L^*a^*b^*When the incident light angle is 45 ° and the light receiving angle is −45 °, (L_{45, 45} ^*, A_{45, 45} ^*, B_{45, 45} ^*), When the incident light angle is 45 ° and the light receiving angle is −20 °, (L_{45, 20} ^*, A_{45, 20} ^*, B_{45, 20} ^*), And using these, ΔE can be determined from the above equation. The black synthetic leather used for such a measurement has a ΔE of 7 or less similarly obtained.
[0012]
The powder of component (A) has a ΔE determined in this manner of 7 to 40, preferably 10 to 35. If it is less than 7, the hue of the skin will change but the transparency will be lost, and if it exceeds 40, the hue will change greatly depending on the angle at which the skin is viewed, giving a sense of discomfort.
[0013]
The particle size of the powder of the component (A) is not particularly limited, but those having an average particle size of 12 μm or less, particularly 5 to 12 μm, are preferred because they provide a good feeling in use and reduce glare.
[0014]
The powder of the component (A) is preferably a powder obtained by coating a base powder with metal oxide particles. As the base powder, one that emits an interference color when coated with metal oxide particles is preferable, for example, mica, plate-like titanium oxide, plate-like iron oxide, plate-like alumina, plate-like silica, fish scale foil, oxy Examples include bismuth chloride, and mica is particularly preferred. Further, as the metal oxide, for example, titanium oxide, iron oxide, zirconium oxide, alumina and the like can be mentioned, and these can be used alone or in combination of two or more, particularly titanium oxide, iron oxide or these. Are preferred. When the coating is performed using a mixture of titanium oxide and iron oxide, the titanium oxide is preferably rutile and does not contain tin. The method for coating the base powder with the metal oxide particles is not particularly limited, and can be performed according to a usual method.
[0015]
Further, by controlling the optical thickness of the metal oxide particles covering the surface of the base powder, various color tones can be produced. And, for example, a powder whose interference color shows a blue-purple color gives a transparent feeling to the skin, and a powder whose interference color shows a green color does not become a dull color, suppresses the redness of the skin, and reduces the interference color. The powder showing an orange-red color can make the skin look healthy and hide the dullness of the skin.
[0016]
Furthermore, by using two or more kinds of powders in combination as the component (A), it is possible to produce various color tones. When two or more powders are used in combination, the ΔE of the powder after mixing is preferably 7 to 40.
[0017]
The surface of the powder of the component (A) is preferably subjected to a hydrophobic treatment from the viewpoint of light resistance. Although ΔE may change due to the hydrophobization treatment, any ΔE after the treatment of 7 to 40 can be suitably used.
[0018]
The hydrophobizing treatment is performed using a hydrophobizing agent, and examples of the hydrophobizing agent include silicone oil, fatty acid metal salt, alkyl phosphoric acid, alkali metal salt or amine salt of alkyl phosphoric acid, and N-mono long chain. (C8-C22) aliphatic acyl basic amino acids, fluorine compounds having a perfluoroalkyl group, and the like.

[0020]
As fatty acid metal salts, those having 12 to 18 carbon atoms are particularly preferable, and as such salts, for example, salts of calcium, magnesium, zinc, aluminum and the like can be mentioned, and aluminum salts are particularly preferable. Therefore, preferable examples of the fatty acid metal salt include aluminum monostearate, aluminum disterate, aluminum monooleate, aluminum monopalmitate, aluminum monolaurate and the like, but are not limited to these examples.

As a method for treating the powder with the N-mono long-chain aliphatic acyl basic amino acid, any of a dry method and a wet method can be used. The dry method is simple and effective, and the fine powder of N-mono long-chain aliphatic acyl basic amino acid is mixed with the powder by stirring, or the powder is mixed with N-mono long-chain aliphatic acyl basic amino acid and the powder. After mixing, the surface of the powder can be easily treated by co-milling. In the wet method, N-mono long-chain aliphatic acyl basic amino acids are hardly soluble in water near neutrality and ordinary oils, and therefore, calcium chloride is used as a solubilizing agent for N-mono long-chain aliphatic acyl basic amino acids. After dissolving the amino acid in an organic solvent, the powder is brought into contact with the powder, further washed with water to remove calcium chloride, and dried, whereby the powder surface can be treated. Alternatively, an N-mono long-chain aliphatic acyl basic amino acid is dissolved in acidic or alkaline water or an aqueous solvent, and the powder is brought into contact with the solution. The same surface treatment can also be performed by depositing and attaching a chain aliphatic acyl basic amino acid, removing the salt generated by neutralization with water, and drying (Japanese Patent Application Laid-Open (JP-A) Nos. 61-7202 and 61-720).
