Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic having high saturation and high concealing property, which hardly causes bleeding with respect to water or sweat.

[0002]

Inorganic pigments, organic pigments, pearl pigments and the like are generally used as colored pigments used in eye colors, lipsticks and the like. In order to improve the feeling of finish when applied, such a point make-up material has a uniform color tone and has a base color (skin and lip color).
It is important that it is not affected by the above, has a high saturation, does not have a dull color due to aging, has sufficient coloring power, and does not stain the application site.

However, from the viewpoint of color tone, red iron oxides such as red iron oxide have a problem that they have low saturation. Furthermore, red iron oxide changes its color to reddish black when it becomes wet with sebum and water secreted from the skin. Further, the yellow hydrated iron oxide has a reduced refractive index when it is wet with sebum or water secreted from the skin. Therefore, point makeup products that use such colored inorganic pigments have the drawback that the coating color becomes dull because it changes to a reddish black color tone over time and it optically reflects the skin color of the base. Was.

On the other hand, as organic pigments, vat dyes such as red No. 226, red No. 202, yellow No. 4 aluminum lake, yellow No. 5 aluminum lake, and blue No. 1 aluminum lake are generally used. However, dyes other than Red No. 226 have a problem of causing bleeding and dyeing at the coating site, but in the organic pigment industry, the elution and dyeing phenomena are unavoidable in view of the chemical structure of these dyes. No effective measures have been found yet. Therefore, when used as a colorant for cosmetics, especially eye colors and lipsticks that are often mixed in large amounts, it remains a problem to suppress the dyeing property to the application site.

In addition, when an organic pigment is blended with lipstick, it is known to reduce the dispersed particles of the pigment as a method of increasing the saturation.
A technique of kneading well using a powerful mixing device such as this roll has been performed, but this technique also causes the dispersed organic pigment to re-aggregate, or the distance between dispersed organic pigment particles. Since they are very close to each other, it is unavoidable that a sufficiently dispersed state cannot be obtained optically, and it cannot be said that the saturation of the organic pigment is sufficiently high.

[0006] In the nail enamel, since there is a large difference in specific gravity between the organic pigment or pearl pigment used in the nail enamel and titanium dioxide, it causes color separation or caking, and in some cases, redispersion is impossible. Therefore, the product value was significantly impaired.

As a technique for improving the drawbacks of the prior art, a general inorganic pigment or organic pigment and a lustrous pigment such as mica titanium are compounded. Examples of such methods include (1) a method of coating the surface of a luster pigment with iron oxide, nickel oxide, cobalt oxide, copper oxide, chromium oxide or the like having a unique color (Japanese Patent Publication No. 63-25644). (2) A method of fixing an aluminum hydroxide layer on the surface of a luster pigment and then fixing the dye on the surface of the pigment by using a chelate-forming agent and a dye having a sparingly soluble salt-forming group (JP-A-51-17910). ). (3) A method of fixing Red No. 202 on the surface of the luster pigment by various methods (Japanese Patent Laid-Open No. 62-169716). (4) A method of coating the surface of the luster pigment with an insoluble salt of an acidic dye and a basic aluminum salt (JP-A-2-34669). (5) A method of improving the dispersibility in a dispersion medium by compounding a pigment with a plastic powder (Japanese Patent Laid-Open No. Sho 5)
(No. 8-187459) (6) A method of mixing Nylon spheres, polyethylene spheres, and spherical silica with Red No. 202 and compounding them by a rotary ball mill (JP-A-4-292664). (7) A method in which a pearlescent pigment having the same surface charge and a colorant are adhered to each other by using a surface charge adjusting agent to obtain a complex gloss pigment having a clear appearance color and an appropriate gloss feeling (JP-A-4-3327).
No. 66). Etc. have been proposed.

[0008]

[Problems to be Solved by the Invention] However, (1)
In the techniques (4), (6), and (7), the coloring power is insufficient and a transparent feeling is obtained, but the coloring property of the pigment remains a problem. Furthermore, the techniques (2) to (6) have a drawback that the organic pigment causes bleeding and is likely to be dyed at the application site.

Therefore, the present invention solves the above-mentioned problems of the prior art, and provides a cosmetic having high saturation and high hiding property, hardly causing bleeding, dispersibility and stability of color tone over time. To do.

[0010]

The inventors of the present invention have conducted extensive studies in order to solve the above-mentioned problems, and as a result, have made calcium carbonate and red No. 202 adhere uniformly and firmly to the surface of a high-refractive-index inorganic white pigment. When the compounded pigment is compounded into a cosmetic, it exhibits much higher chroma and high hiding power than when simply compounded with a high refractive index inorganic white pigment and Red No. 202.
Further, they have found that bleeding is unlikely to occur in water, sweat and ethanol, and that they are excellent in dispersibility in the formulation and stability of color tone over time, and have completed the present invention.

That is, the present invention has high saturation and high concealability,
(EN) Provided is a cosmetic which does not stain Red 202 and has excellent color stability over time.

The present invention will be described in detail below.

The organic-inorganic composite pigment which is applied to the present invention and which is obtained by firmly coating the inorganic white pigment with calcium carbonate and Red No. 202 is (1) Red No. 201 and / or Red No. 202 as a lower alcohol. And (2) a step of dispersing an inorganic white pigment in a lower alcohol solution in which Red No. 201 and / or Red No. 202 is dissolved, and (3) an inorganic white pigment by adding an alkali agent to the lower alcohol solution. A step of depositing Red No. 201 and / or Red No. 202 on the surface, and (4) adding a lower alcohol solution of calcium chloride to the lower alcohol solution to generate and deposit calcium carbonate on the surface of the inorganic white pigment, Red No. 201 and / or Red No. 2 deposited on the surface of the white pigment
No. 02 is laked or re-laked, and calcium carbonate and red No. 202 are fixed to the surface of the inorganic white pigment.

The steps (1) and (2) may be carried out before or after, or at the same time.
Alternatively, in order to confirm the dissolved state of Red No. 202 and the dispersed state of the inorganic white pigment, it is preferable to follow the above procedure.

Lower alcohols for dissolving Red No. 201 and / or Red No. 202 and dispersing the inorganic white pigment are methanol, ethanol, isopropyl alcohol, n-propyl alcohol, isobutanol, sec.
-Butanol, tert-butanol, n-butanol and the like can be used alone or in combination of two or more.

When the lower alcohol has a high water content, the inorganic white pigment is strongly aggregated when the alkaline agent is added in the step (3), resulting in an organic-inorganic composite pigment in a non-uniform coating state. The water content is 5%
It is desirable to use less than lower alcohols.

Next, red No. 201 and / or red No. 202 is dissolved, and an alkali carbonate or a solution thereof is added to a lower alcohol solution in which an inorganic white pigment is dispersed, and red No. 201 and / or red No. 202 is added. Deposit on the surface of the inorganic white pigment. Na ₂ CO as the carbonate carbonate
_One or two or more of ₃ , K ₂ CO ₃ and Li ₂ CO ₃ can be suitably used as they are or as an aqueous solution, a lower alcohol solution or a hydrous lower alcohol solution, and the concentration thereof is not particularly limited, but the red No. 201 and / or Alternatively, since it is necessary to introduce an amount sufficient to deposit Red No. 202 on the surface of the inorganic white pigment, it is desirable to use it as a solution having a concentration as high as possible from the viewpoint of work efficiency.

Then, in the step (4), calcium carbonate is generated and deposited on the surface of the inorganic white pigment, and the red No. 201 and / or the red No. 202 deposited on the surface of the inorganic white pigment are laked with calcium chloride or Re-lake and firmly fix in the form of Red No. 202.
As calcium chloride, any form of anhydrous salt, dihydrate and hexahydrate can be preferably used. As a solvent for dissolving calcium chloride, lower alcohols such as methanol, ethanol and isopropanol can be used, but lower alcohols having a water content of less than 0.5% are preferable because the dissolution rate of calcium chloride is faster. Although the concentration to be used is not particularly limited, it is advantageous to use a solution having a concentration as high as possible from the viewpoint of work efficiency.

Calcium carbonate is produced and deposited on the surface of the inorganic white pigment with calcium chloride, and red No. 201 and / or red No. 202 deposited on the surface of the inorganic white pigment are laked or relaked before use. The reaction is preferably aged at a temperature not higher than the boiling point of the solvent, preferably around room temperature. The reaction aging time may vary depending on the aging temperature, but if it is less than 3 hours, the bluish red color which is the original color of Red No. 202 may not be obtained,
Even if the aging is carried out for 5 hours or more, there is substantially no change in color tone, so it is desirable to carry out the aging for 3 to 5 hours.

After completion of the reaction aging, the obtained organic-inorganic composite pigment is filtered and washed. As a method for filtering the organic-inorganic composite pigment, known methods such as pressure filtration, vacuum filtration, natural filtration, centrifugation, decantation and the like can be used. As a solvent used for washing the obtained organic-inorganic composite pigment, water, lower alcohol, or a mixture of two or more kinds of these can be used.

When drying the organic-inorganic composite pigment obtained by coating the surface of the finally obtained inorganic white pigment with calcium carbonate and Red No. 202, it is desirable to dry at a temperature of 60 ° C. or lower. When it is dried at a temperature over 60 ° C., a color shift phenomenon in which the color tint of Red No. 202 shifts to a bluish color is more likely to occur. The drying time depends on the solvent used for washing, but usually 4 to 30 hours is sufficient.

The inorganic white pigment to be coated preferably has a refractive index of 2 or more. When a material having a refractive index of less than 2 is used, the transparency becomes strong, the form of the base is easily visible, and the color tone of the undertone of the base is affected, so that a pigment with high saturation and high hiding power cannot be obtained. Such inorganic white pigments having a refractive index of 2 or more include zinc oxide (refractive index 2.0), zirconium oxide (refractive index 2.4), anatase type titanium oxide (refractive index 2.5), rutile type oxidation. Titanium (refractive index 2.
75) or a mixture or a mixture of two or more kinds of these can be preferably used.

The shape of the inorganic white pigment is not particularly limited, but the average particle diameter is preferably in the range of 0.1 to 60 μm. If the average particle size is less than 0.1 μm, the hiding power of the pigment is lowered, and it is difficult to obtain an optically sufficient pigment dispersion state. If the average particle size exceeds 60 μm, not only is sufficient coloring power not obtained. You can feel the graininess,
Not desirable as a cosmetic.

The amount of Red No. 202 coated on the inorganic white pigment can be selected according to the desired tint. If the amount of Red No. 202 adhered to the surface of the inorganic white pigment is increased, the reddish organic color will be deep. -Inorganic composite pigment can be obtained. However, if the weight ratio of the inorganic white pigment to Red No. 202 exceeds 1: 1, the red color does not substantially darken. Therefore, it is preferable to appropriately select within this range.

Hereinafter, the organic-inorganic composite pigment applied to the present invention will be described in more detail with reference to production examples.

Production Example 1. 200 g of 95% ethanol was weighed into a glass container, and 2 g of Red No. 202 (manufactured by Daito Kasei) was added with stirring to completely dissolve it. 8 g of titanium oxide A-100 (manufactured by Ishihara Sangyo Co., Ltd.) was added to this solution, and stirring was continued for 30 minutes using a homomixer to uniformly disperse the mixture.
