Description

cosmetic composition

Field

The present invention relates to a cosmetic composition suitable for obtaining a bright, natural complexion with a sense of transparency.

Background technique

So far, the coloring pigments used in cosmetics include inorganic pigments such as iron oxide pigments, Prussian blue, ultramarine blue and chromium oxide, and organic pigments such as No. 201 red, No. 401 yellow, No. 1 blue, and No. 3 green. When these conventional coloring pigments are added to cosmetics, especially when a large amount of coloring pigments are added for coloring into skin color, the resulting cosmetic composition forms a dull coating due to the light-scattering effect of the coloring pigments and lacks a sense of transparency.

Therefore, in order to obtain a glossy coating, the method of adding pearlescent pigments has been adopted, wherein the pearlescent pigments (such as mica coated with titanium dioxide) obtain the pearlescent effect by coating low refractive substances with high refractive substances. However, if the pearlescent pigment with pearlescent pigment is added to the pigment-containing cosmetic composition, the sufficient effect cannot be achieved when the amount of the pearlescent agent is small, because the disturbing light reflected by the pearlescent pigment will be absorbed and scattered by the colored pigment. On the other hand, increasing the amount of pearlescent pigment to a certain extent, the effect of lightening can be actually perceived, but in some cases, the difference in brightness between the angle of disturbing light with reflection and the angle of disturbing light without reflection can be very large , which can result in an unnaturally dazzling coating.

Therefore, it has been proposed to use colored titanate mica in which titanate is directly coated with a coloring pigment to prevent the coloring pigment from absorbing or scattering light (Japanese Laid-Open Patent Applications Nos. 81334/1996 and 16198/2000). Japanese pending patent application 81334/1996 discloses titanate mica colored by a colorant for repairing skin color and covering redness, while Japanese pending patent application 16198/2000 discloses a small amount of - 15 μm finely milled mica pigments are used to apply complexion pigments. When this colored titanate mica is used as a coloring agent in cosmetics, and the resulting cosmetic composition is applied to a wide area such as the entire face, the part of the face facing the observer will have a different chromaticity from other parts because of the coloring. The color of the pigment is different from the color of the reflected interference light produced by titanate mica, so that the make-up will form an unnatural coating. When preparing the pigment of the cosmetic composition, in order to make the colored titanate mica into a skin color, it is necessary to additionally add a sufficient amount of iron oxide pigment, titanium dioxide, titanate mica, and the like. Then the result is insufficient to obtain a glossy and natural coating with a sense of transparency.

Another object of the present invention is to provide a cosmetic composition capable of obtaining a glossy and natural coating with a sense of transparency.

invention disclosure

The present inventors found that adding two kinds of yellow and red flaky colored pigments to a cosmetic composition, which is prepared by using flaky powders with different refractive indices as a base layer and additionally coating a coloring agent thereon, the resulting The cosmetic composition is applied to the skin to obtain a glossy and natural coating with a sense of transparency.

The present invention provides a cosmetic composition containing two kinds of flaky colored pigments, wherein the pigments are coated with a powder having a refractive index of at least 2.0 on the surface of a flaky powder having a refractive index lower than 2.0, and then coated In the Munsell notation system, the apparent (visual) color hue of one flake pigment is 10P to less than 5YR, and the hue of the apparent color of the other pigment is It is 5YR-10GY.

BEST MODE FOR CARRYING OUT THE INVENTION

One of the flaky coloring pigments suitable for use in the cosmetic compositions of the present invention is a red pigment having an apparent color hue in the Munsell notation system of 10P to less than 5YR, preferably 2.5RP to 2.5YR, particularly preferably 10RP to 10R. Another flake coloring pigment is a yellow pigment having an apparent color hue of 5YR to 10GY, preferably 7.5YK to 10YR, particularly preferably 10YR to 7.5Y, in the Munsell notation system.

The refractive index of the flakes forming the matrix of the flake colored pigments is lower than 2.0, preferably lower than 1.8. Examples of the flaky powder include mica, sericite, talc, flaky alumina powder, flaky silica, flaky barium sulfate, etc. Among them, mica is particularly preferable because it has high transparency and does not scatter reflected light. of interfering light.

The powder used for coating flakes (hereinafter referred to as "coating powder") has a refractive index of at least 2.0, preferably at least 2.2. The coating powders can be used singly or in combination. Examples thereof include titanium dioxide, zinc oxide, yellow iron oxide, red iron oxide, black iron oxide, chromium oxide, and the like. Among them, at least titanium dioxide is preferably contained, because the coating powder can have a high refractive index without affecting the hue of the obtained flaky colored pigment.

The flake powder forming the matrix of the flake colored pigments can be coated with a metal oxide, such as iron oxide, aluminum oxide or tin oxide, coated with a metal hydroxide, such as iron hydroxide or aluminum hydroxide, coated with a metal, Such as gold, silver or aluminum, or coated with salts, such as inorganic salts or organic salts, to control the thickness and/or crystal shape of the optical coating formed by coating the powder.

The surface of the coated flake powder is further coated with a colorant such as that found in "Saishin Keshohin Kagaku" (New Cosmetic Science) (2nd Edition revised and supplemented) (Edited by Japan Cosmetic Engineer Society, published by Yakuji Nipposha) 330 - 387 pages such as Yellow Iron Oxide, Red Iron Oxide, Black Iron Oxide, Prussian Blue, Chrome Oxide, Tar Pigments and Natural Pigments.

The use of inorganic colorants such as iron oxide, chromium oxide, and Prussian blue is particularly preferred because the resulting cosmetic composition has excellent resistance to dissolution by water, oil, etc., with little discoloration.

For example, red flake colored pigments with hues from 10P to less than 5YR in the Munsell notation system include inorganic red pigments, especially red iron oxide, because of their ability to produce natural skin tones. On the other hand, the yellow flake colored pigment having a hue of 5YR to 10GY in the Munsell notation system preferably includes an inorganic yellow pigment, especially yellow iron oxide.

Methods for coating the coated flakes include a method of attaching by chemical reaction, and a method of physically attaching by mechanical pressure.

The coating colorant is preferably used in an amount of 1 to 20% by weight of the flake coloring pigment, since thereby sufficient coloring power is obtained so that reflected interference light is not weakened.

At least one of the above-mentioned two flake coloring pigments used in the present invention preferably has a difference in chroma (C ^* _Bk , C ^* _Wh ) for black artificial leather and white artificial leather (ΔC ^* _(Bk-Wh) =C ^* _Bk- C ^* _Wh ) is -10.0 to 10.0, especially -5.0 to 5.0, which is applied on black artificial leather and white artificial leather with flake colored pigment at a coating weight of 0.5 g/m ² , both surfaces being treated Measured by a colorimeter, where the incident light angle is 45° and the received light angle is -45°, and when the flaky coloring pigment is coated on white artificial leather at a coating weight of 0.5 g/ ^m2 , and When the incident light angle is 45° and the received light angle is 0°, the chromaticity (C ^* _Ow ) measured by a colorimeter is at least 10.0, especially at least 15.0.

The change in the color of the coating as a function of the reflection of visible light on the coating medium becomes very small when the chromaticity difference ΔC ^* _(Bk-Wh) is between -10.0 and 10.0. On the other hand, when C ^* _OW is at least 10.0, a more sufficient coating effect can be exhibited. Preference is therefore given to using such flake colored pigments.

The chromaticity difference ΔC ^* _(Bk-Wh) was measured by the following method.

Colored titanate mica samples were uniformly coated on black and white artificial leather, respectively, in a coating amount of 0.5 g/m ² , and passed through a colorimeter (eg, goniospectrophotometer GCMS-3 manufactured by Murakami Shikisai Kagaku Kenkyusho) ) Establish chromaticity coordinates L ^* , a ^* , b ^* in the CIE 1976 L ^* a ^* b ^* color zone, where the incident light angle and received light angle are 45° and -45° respectively. Each chromaticity value is then calculated according to the equation C ^* =(a ^*2 +b ^*2 ) ^1/2 . At the same time, if the chromaticity of black artificial leather is C ^* _Bk and the chromaticity of white artificial leather is C ^* _Wh , then the difference C ^* _Bk -C ^* _Wh is recorded as ΔC ^* _(Bk-Wh) . When the present invention adopts black and white artificial leather, when the incident angle is 45° and the acceptance angle is 0°, for the black artificial leather adopted, L ^* is 20-25, a ^* is -5-5, and b ^* is -5-5, for white artificial leather, L ^* is 90-95, a ^* is -5-5, and b ^* is 0-10.

For each flaky coloring pigment, it is further preferred that the difference ΔC ^* _(45-0) =C ^* _45B -C ^* _0B is 0-20.0, especially 0-15.0, which means that the flaky coloring pigment is evenly coated on the black artificial leather And the difference between the chromaticity C*45B measured when the incident light angle ^{is 45° and the received light angle is -45° by the colorimeter and the chromaticity C*} _0B ^measured _when the received light angle is 0°. This chromaticity difference ΔC ^* _(45-0) is preferred, since the chromaticity variation of the angle-dependent surface reflection on the coating thus becomes very small.

For flake colored pigments, the preferred pigment is a pigment obtained by coating a layer of yellow iron oxide on the surface of titanate mica coated with titanium dioxide coating, wherein the thickness of the titanium dioxide optical coating is 140-240nm, Or coat a layer of red iron oxide pigment on the surface of titanate mica coated with titanium dioxide coating, wherein the thickness of the titanium dioxide optical coating is 220-320nm, and on the titanium dioxide coated titanium A layer of Prussian blue pigment is coated on the surface of salt mica, wherein the thickness of the titanium dioxide optical coating is 290-390nm, this is because the flake coloring pigment is coated separately with a coating weight of 0.5g/m ² The chromaticity (C ^* _BK , C ^* _Wh ) difference (ΔC ^* _(Bk-Wh) = C ^* _Bk -C ^* _Wh ) will become very small.

The titanate mica constituting the colored titanate mica matrix can be prepared by various known methods. For example, it can be prepared by the following method: through neutralization or hydrolysis, titanium inorganic salts such as titanyl sulfate and titanium tetrachloride are decomposed in the presence of mica, so that hydrous titanium hydroxide or titanium dioxide is deposited, and then the sediment is deposited at 500-1000 °C, preferably 700-900 °C in air (Japanese Patent Laid-Open Publication No. 25644/1968).

Mica suitable for use herein include muscovite, biotite, phlogopite and synthetic mica.

For the raw materials of colored pigments forming colored titanate mica, aqueous solutions of inorganic and organic iron compounds, iron(II) chloride, iron(III) chloride, iron(II) sulfate, iron(III) sulfate can be used ), Iron(II) Nitrate, Iron(III) Nitrate, Iron(II) Oxalate, Iron(III) Ammonium Oxalate, Iron(III) Ammonium Sulfate, Iron(III) Phosphate, Iron(III) Citrate, Lactic Acid Ferrous Iron(II), and Iron Fumarate. Colored titanate mica can be prepared by adding titanate mica to an aqueous solution of inorganic and organic iron compounds, heating the mixture to deposit hydrolysis products of the iron compound, and then washing the deposit with water and drying. Alkali, such as sodium hydroxide, potassium hydroxide, ammonium and amine, and aqueous solutions of the above alkalis can also be added before or after titanate mica is added to the aqueous solution of inorganic or organic iron compounds to control the rate of hydrolysis.

To prepare, for example, titanate mica coated with yellow iron oxide, an aqueous solution of inorganic and organic iron compounds can be added to titanate mica, wherein the optical layer thickness of the titanium dioxide coating is 140-240 nm, and the mixture is heated to 50 -100°C, preferably 80°C or higher to hydrolyze the iron compound so that yellow iron oxide is deposited on the surface of the titanate mica, the deposit is washed with water, filtered, and dried at 150°C or lower .

The known preparation method of titanate mica can be used to prepare the titanium dioxide coating with the above optical layer thickness by controlling the concentration of titanium salt, the hydrolysis temperature of titanium salt, the hydrolysis time of titanium salt, and the surface treatment of titanium dioxide coated mica. layer.

Red iron oxide coated titanate mica can be prepared by depositing iron oxide by the method described above using titanate mica coated with titanium dioxide having an optical layer thickness of 220-320 nm, washing the deposit with water, The deposit is dried and calcined at 150°C or higher, preferably 400°C or higher.

Prussian blue-coated titanate mica can be prepared by applying an aqueous solution of sodium ferrocyanide and iron(II) sulfate to titanate mica coated with a titanium dioxide coating having an optical layer thickness of 290 -320nm. After titanate mica is added with sodium ferrocyanide and ferrous sulfate (II) aqueous solution, ammonium sulfate is added, and the resulting mixture is matured under acidic conditions with sulfuric acid and oxidized by sodium chlorate, so that Prussian blue is deposited on titanium. salt mica surface. The product was washed with water, filtered, and dried to prepare Prussian blue-coated titanate mica.

The coating rate of the colorant is preferably 1 to 20% by weight of the coated titanate mica. When the coating rate falls within this range, the reflected disturbing light will not be weakened, and sufficient coloring power can be obtained. The intensity of reflected interfering light is preferably at least 30.0 in the chromaticity coordinate L ^* in the CIE 1976 L ^* a ^* b ^* color zone, which is obtained by uniformly coating colored titanate mica at a coating weight of 0.5 g/ ^m2 on Measured on black artificial leather and measured by a colorimeter at an incident light angle of 45° and a received light angle of -45°. The coloring powder is preferably such that the chroma (C ^* _OW ) is at least 10.0, which is that the flake coloring pigment is uniformly coated on the white artificial leather at a coating weight of 0.5 g/m ² and measured by a colorimeter when the incident angle is 45 °, measured when the acceptance angle is 0°.

The flake colored pigments suitable for use in the present invention may also be hydrophobically treated. Examples of suitable hydrophobic treatment agents include silicone oils, metal salts of fatty acids, alkyl phosphates, alkali metal or amine salts of alkyl phosphates, N-mono long chain (C _8-22 ) aliphatic acylated basic amino acids and fluorinated compounds containing perfluoroalkyl groups.

The average particle diameter of each flake-shaped coloring pigment is preferably 1-40 μm, especially 2-30 μm, from the viewpoint of preventing the color from being dull due to visible light scattering affecting the sense of transparency, so that users will not be disturbed by a large amount of reflected light from the surface. Create a dazzling feeling. The particle diameter was measured using a laser scattering particle size distribution analyzer LA-920 manufactured by Horiba Ltd., in which ethanol was used as a dispersion medium.

In the cosmetic composition, the addition amount of the flaky colored pigment is 5-50% (weight) based on the total amount of the two flaky colored pigments, preferably 10-30% (weight), wherein the hue of the two flaky colored pigments 10P to below 5YR, and 5YR-10GY. The mixing ratio of the two flake colored pigments is not particularly limited. However, it is preferred that the resulting cosmetic composition has a hue of 2.5R-10Y in the Munsell scale and a lightness of at least 3.0, so that a lustrous, skin-colored coating can be obtained.

The cosmetic composition of the present invention is suitable for adding ingredients commonly used in conventional cosmetic compositions, such as surfactants, polymers, oils, other powders, moisturizers, preservatives, medicinal active ingredients, ultraviolet absorbers, antioxidants , inorganic or organic salts, flavor bases, chelating agents, pH regulators, water, etc.

Examples of the cosmetic composition of the present invention include foundation, face powder, concealer, blush, eye shadow and eyebrow pencil. As a cosmetic composition that is easy to obtain a coating having a sense of transparency and gloss and skin tone, it is preferable that it is a foundation, a face powder, and a concealer, and among them, a foundation is particularly preferable.

^* 1: TIMIRON MP-1005 Product of MERCK Co.

The solid foundation product of the invention can obtain a glossy, transparent coating with a natural skin color and low glare.

On the other hand, the comparative foundation product 1 had no glare, but since its coloring pigments scatter visible light, it formed a dull and heavy coating, lacking a sense of transparency.

The control product 2, which contains titanate mica, gives a glossy coat, but it dazzles the coat due to an unnatural sheen and makes the skin texture more visible.

Contrast products 3 and 4 containing a class of commercially available colored titanate mica do not have a dazzling feeling, but compared with the products of the present invention 1-3, they have "transparency in the coating" and "bright coating" , "Natural skin tones" are less effective because visible light is scattered by their coloring pigments.

The comparison products 5 and 6 containing only one kind of colored titanate mica of the preparation examples formed unnatural skin color, which was caused by the color of the interfering light reflected by the colored titanate mica itself.

For the comparative example 7 that adopts two types of commercially available colored titanate micas, it is necessary to add a large amount of colored titanate micas to achieve the skin color, and to obtain a "bright coating", but it is different from the products of the present invention 1-3 In contrast, "Coating is transparent" and "Natural skin tone" perform poorly because of their unnatural glare.
