Description

  The present invention relates to a colored composite interference pigment having a bright colored appearance and a cosmetic containing the same. More specifically, a composite powder obtained by coating a specific powder metal colloid on a plate-like powder having an interference color, such as foundation, eye shadow, lipstick, gloss, mascara, eyeliner, nail enamel, nail enamel base coat, cream, emulsion, etc. The present invention relates to a cosmetic material that is blended in a cosmetic material and has an excellent stability and a vivid colored appearance.

  Most cosmetics, especially makeup cosmetics such as foundations, lipsticks, and nail enamels, are blended with organic pigments, inorganic pigments, or pearl agents such as titanium mica in order to impart a makeup effect.

  However, among these pigments, inorganic pigments are excellent in stability but have low saturation and it is very difficult to obtain vivid color development. Conversely, organic pigments can obtain vivid color development, but cosmetics In many cases, the color tone changes greatly when irradiated with light, and the stability is very poor.

  Therefore, studies have been made focusing on fine-particle metal colloidal sol as a highly stable and highly saturated colorant. According to the principle called plasmon coloring, these fine particle metal colloids exhibit red in the case of gold because of absorption near 550 nm, and in the case of silver and mercury, they exhibit yellow on the low wavelength side of 450 nm or less. It is known. Many patents using this principle have been filed.

  However, as described in these patents, when a metal sol is blended in a cosmetic as it is, a vivid color can be obtained, but there is a drawback that all are covered with the same color. In addition, immobilization in metal oxides overcomes the drawbacks, but often lacks vividness, and the vividness of metal colloids is lost, reducing the attractiveness of cosmetics by half. There was a tendency to end up.

  As a result of intensive studies to solve the above problems, the present inventors fixed a metal colloidal sol having a specific particle size to a plate-like powder having an interference color, and optionally one or more metal oxides and metals. It has been found that the above-mentioned problems can be solved by obtaining a composite interference pigment coated with a hydroxide and blending it into a cosmetic, and the present invention has been completed.

  An object of the present invention is to provide a plate-shaped composite interference pigment in which specific metal colloidal particles are immobilized, and to provide a cosmetic that vividly develops color without impairing stability by blending it into the cosmetic. That is.

  That is, the present invention is characterized in that a plate-like powder having an interference color is coated with a fine particle metal colloid having a particle diameter of 1 to 40 nm, and optionally further coated with one or more metal oxides or metal hydroxides. The present invention provides a composite interference pigment.

  In addition, the present invention provides the above-described composite interference pigment, wherein the particulate metal colloid is gold, silver, or platinum, and the coating amount is 0.001 to 20% by mass with respect to the total amount of the composite powder. To do.

  Further, in the present invention, the plate-like powder having the interference color is mica titanium, titanium oxide coated synthetic mica, titanium oxide and silicon oxide coated mica, titanium oxide coated glass flake, titanium oxide coated silica flake, titanium oxide coated alumina flake. The above-described colored composite interference pigment is characterized by being any one of silica-coated mica, silica-coated synthetic mica, silica-coated glass flakes, titanium oxide flakes, and silica-coated aluminum.

Further, the present invention provides the above colored composite, wherein a difference in hue between the appearance color and the interference color of the colored composite interference pigment has a hue H (Hue) value within 10 in the Munsell color system. An interference pigment is provided.
That is, in the present invention, it is preferable that the composite plate-like powder interference color and the metal colloid have similar colors. Specifically, the hue H value in the Munsell color system is shown within ± 5 as a result of measuring the composite plate-like interference pigments coated on the white base and the black base.

  Furthermore, the present invention provides that the metal oxide or metal hydroxide is titanium, silicon, aluminum, zirconium, or zinc, and the coating amount of the metal oxide or metal hydroxide is the total amount of the composite interference pigment. The above composite powder is provided in an amount of 0.005 to 80% by mass.

  Moreover, this invention provides the cosmetics characterized by mix | blending 0.05-80 mass% of said composite interference pigment with respect to cosmetics whole quantity.

  The colored composite interference pigment powder in which metal colloidal particles are immobilized on a plate-like powder having interference color according to the present invention provides a cosmetic that produces a vivid color without impairing stability by being incorporated into the cosmetic. Is possible.

  Hereinafter, the present invention will be described in detail.

  The colored composite interference pigment powder of the present invention is a plate-like powder obtained by coating a plate-like powder having an interference color with a fine metal colloid. As the fine particle metal colloid, a commercially available metal colloid sol can be used. The average particle size of the fine metal colloid is 1 to 40 nm, preferably 3 to 20 nm. When the particle diameter exceeds 40 nm, the plasmon coloring effect is lost and no specific absorption is exhibited, and only a metallic color appears. The coating amount is 0.001 to 20% by mass, preferably 0.01 to 5% by mass, based on the total amount of the plate-like powder. If the coating amount is less than 0.001% by mass, the color tone becomes too thin and a vivid appearance cannot be obtained. On the other hand, if it exceeds 20% by mass, the density is too high and the brightness is lowered, so that a vivid appearance cannot be obtained.

As the plate-like powder having an interference color used in the present invention, a plate-like powder having an interference color used in cosmetics can be used. For example, mica titanium, titanium oxide coated synthetic mica, titanium oxide and silicon oxide coated mica, titanium oxide coated glass flake, titanium oxide coated silica flake, titanium oxide coated alumina flake, silica coated mica, silica coated synthetic mica, silica coated glass flake, Examples thereof include titanium oxide flakes and silica-coated aluminum. Having interference light has an effect of enhancing the color emitted by the metal colloid. Commercially available products include, for example, mica titanium, Bengala coated mica, Bengala coated mica titanium, carmine coated mica titanium, bitumen coated mica titanium, titanium oxide coated synthetic phlogopite, Bengala / titanium oxide coated synthetic phlogopite, titanium oxide coated glass flakes, Titanium oxide-coated alumina flakes (Silona Silver manufactured by Merck), Titanium oxide-coated silica flakes (Silona Magicmove manufactured by Merck), iron oxide / silica-coated aluminum, iron oxide / silica-coated iron oxide, titanium oxide and oxidation Silicon-coated mica (Merck Co., Ltd., Chimiron Splendid Gold, Sirona Caribbean Blue, etc.), titanium oxide-coated glass flakes (Nippon Sheet Glass Co., Ltd., Metashine MC1080RR, Engelhard Co., Ltd., Reflex series, etc.) can be used. Among them, titanium oxide-coated synthetic mica, titanium oxide-coated glass flakes, titanium oxide-coated silica flakes, titanium oxide-coated alumina flakes, silica-coated mica with a white appearance that has little interference with the coloring effect of metal colloids and has a high interference color. Silica-coated synthetic mica, silica-coated glass flakes, titanium oxide flakes, and silica-coated aluminum are desirable.
In particular, since the color tone becomes particularly vivid when the difference between the appearance color and the interference color hue of the colored composite interference pigment is small, the difference between the appearance color and the interference color hue is the hue H (Hue) value in the Munsell color system. It is desirable to have a value within 10.

  The method for producing the composite powder of the present invention is not particularly limited. For example, the fine metal particles prepared by reducing chloroauric acid are stirred with the plate-like powder under acidic conditions or in an alcohol solvent such as ethanol or IPA. By doing so, a method of coating the powder surface with metal fine particles can be mentioned.

  In some cases, the metal colloid-coated composite powder obtained above can be further coated with one or more metal oxides or metal hydroxides. As the metal oxide and metal hydroxide to be coated, one or more kinds of known components can be coated by a known method. For example, iron oxide and iron hydroxide can be used, but the metal oxide or metal hydroxide is preferably titanium, silicon, aluminum, zircon, or zinc. In particular, white titanium hydroxide, titanium oxide, silicon hydroxide, silicon oxide, aluminum hydroxide, aluminum oxide, zinc hydroxide, zinc oxide and the like are desirable. By coating these, elution of the coated metal colloid into the system can be suppressed, and the brightness and saturation of the appearance can be controlled by controlling the reflectance of the surface.

  The composite powder in which the metal colloid-coated composite powder is further coated with a metal oxide or metal hydroxide can be coated with titanium oxide or titanium hydroxide by, for example, titanyl sulfate method or titanium tetrachloride method. A metal hydroxide can be produced by hydrolysis of an alkoxide, and further coated with a metal oxide by firing at about 100 ° C. to 800 ° C. A specific production method will be described later in Examples. The colored composite pigment powder produced in Examples 2 and 4 is a powder in which a metal oxide or a metal hydroxide is further coated on a coated metal colloid. That is, there is a plate-like interference pigment powder, a metal colloid is present on the surface thereof, and a metal oxide or metal hydroxide is further coated thereon.

  The coating amount of the metal oxide or metal hydroxide is not particularly limited, but is preferably 0.005 to 80% by mass with respect to the total amount of the composite powder. If the coating is further performed, the color of the metal colloid tends to be lowered, and the attractiveness of the appearance is reduced.

  The composite powder obtained above is a colored powder that is extremely excellent as a raw material for cosmetics. The compounding quantity to cosmetics is 0.05-80 mass% with respect to cosmetics whole quantity, Preferably it is 1.0-40 mass%. If it is less than 0.05% by weight, a sufficient coloring effect cannot be obtained. On the other hand, if it exceeds 80% by weight, the prescription width for containing other raw materials becomes very narrow, and the physical properties of the product such as viscosity and hardness cannot be adjusted. .

Cosmetics that can be blended with the composite powder of the present invention are not limited. For example, makeup cosmetics such as foundation, eye shadow, lipstick, gloss, mascara, eyeliner, nail enamel, nail enamel base coat, basic cosmetics such as lotion, milky lotion, cream, hair cosmetics such as hair spray, hair oil Etc., the cosmetic powder of the present invention can be obtained by blending the composite powder.
In particular, makeup cosmetics are preferred.

  In the cosmetics of the present invention, solid, semi-solid and liquid oils, water, water-soluble polymers, polyhydric alcohols, solvents, surfactants, powders, as needed, to the extent that the effects of the present invention are not impaired. Resin, organically modified clay mineral, polymer, UV absorber, moisturizer, antiseptic, bactericidal agent, fragrance, antioxidant, skin beautifying ingredient, bioactive ingredient powder, pigment, dye, pearl agent, lame agent, drug, Ingredients generally blended in cosmetics such as humectants, ultraviolet absorbers, matting agents, fillers, surfactants and metal soaps can be blended.

  The present invention will be described more specifically based on examples. The present invention is not limited to the following examples. The blending amount is mass% unless otherwise specified.

Prior to the description of each example, the appearance color of the manufactured powder and the hue color measurement method of the interference color are described below.
Various plate-like composite powders are uniformly stirred and mixed at a ratio of 1 (powder) / 15 (nitrocellulose lacquer) with nitrocellulose lacquer (Musashi Paint Co., Ltd.), and 0.101 mm is applied to the color matching paper on the black and white base. A membrane was created. Using the integrating sphere spectrophotometer CM-2600d (Minolta), the hue H (Hue) in the Munsell color system was measured for each of the coating on the white base and the coating on the black base. . At this time, the color measurement result on the white background was used as the color tone of the appearance color, and the color measurement result on the black background was used as the color tone of the interference color.

[Evaluation as pigment]
In order to evaluate the composite powders of Examples 1 to 6 produced above as pigment powders, the following two items were evaluated.

[Vividness]
The freshness of the appearance of the composite powders of Examples 1 to 6 was evaluated according to the following evaluation criteria by a specialized panel (10 persons) engaged in color tone inspection. In the comparative example, Merck's Cororona Carmine Red, a mica titanium coated with carmine, an organic colorant with a bright red appearance color, Bengala, an inorganic colorant with a highly stable red appearance color. A Coronona Bordeaux made by Merck Co., which is a coated mica, was used.
<Evaluation criteria>
◎: Eight or more people judged vivid ○: Five to seven people judged vivid △: Two to four people judged vivid ×: One or less people judged vivid

[Light stability]
In order to evaluate the light stability, the sample was irradiated with light, and the color difference before and after that was measured. As a measurement method, the coating film prepared in the above section was irradiated with xenon light at 50 ° C. for 30 hours. Then, using the same method described above, the L * value (brightness), a * value (redness), and b * value (yellowness) in the L * a * b * color system are obtained, and the color difference is calculated from the following formula. Asked. The smaller this color difference is, the better the light stability is.
[Equation 1]
Color difference = {(L * value after irradiation-L * value before irradiation) ² + (a * value after irradiation-a * value before irradiation) ² +
(B * value after irradiation-b * value before irradiation) ² } ^0.5

The results of the composite powder and the control product are shown in Table 1 together with the H value.

  As shown in Table 1, it was confirmed that the composite powders A to E were very vivid, the color difference was small, and the light stability was excellent. The composite powder F was also vivid although its vividness was slightly inferior from A to E. Although the color of the corona carmine red of the comparative example was vivid, it was confirmed that the color difference was large and the light stability was poor. On the other hand, the color of cororo na Bordeaux was good, but lacked vividness. From this, it was confirmed that the composite powders A to F were superior to those listed in the comparative examples.
