The present invention relates to cosmetics containing a novel pigment having colored pearlescent luster. Mica titanium pigments, which have traditionally been used in cosmetics, are included in the Cosmetic Raw Materials Standards Supplementary Commentary, 6th Edition, P.54.
~As described in P.57 (published in 1981, Yakuji Nipposha), it is made by forming a titanium dioxide layer on the surface of fine flaky mica, and has pearlescent luster and various interference colors. However, the exterior color is always close to white,
None exhibited a bright external color that matched the interference color. Conventionally, in order to produce a variety of external colors, colored pigments such as iron oxide, navy blue, chromium oxide, carbon black, and carmine were added to the produced mica titanium pigment. The safety, stability, light resistance, acid resistance, alkali resistance, solvent resistance, heat resistance, etc. of these colored mica titanium pigments are largely due to the properties of the colored pigments added.For example, blue mica with navy blue added. Titanium-based pigments discolor in alkaline solutions, and red mica titanium-based pigments containing carmine discolor and deteriorate when exposed to light. On the other hand, the carcinogenicity of 3,4-benzpyrene, which may be mixed into carbon black, such as black mica titanium pigments containing carbon black and green mica titanium pigments containing chromium oxide, There are many safety concerns, such as the oral toxicity of hexavalent chromium. Furthermore, since the colored mica titanium pigments mentioned above contain colored pigments, when added to cosmetics, etc., they may sometimes cause fading or color separation in the product, or may cause odor changes due to the activity of the colored pigments. There were drawbacks such as waking up. The present inventors have conducted extensive research in view of the above circumstances, and have found that the mica surface is coated with a lower titanium oxide, a titanium oxynitride, or a titanium compound containing at least one of a lower titanium oxide and a titanium oxynitride, Furthermore, mica coated with a titanium compound whose surface is coated with titanium dioxide has excellent color tones such as brightness and chroma, and has a good match between external color and interference color, and has stability, safety, light resistance, and acid resistance,
It was discovered that the pigment has excellent properties such as alkali resistance, solvent resistance, and heat resistance. Furthermore, when this product is added to cosmetics, it disperses well and prevents fading.
We discovered that it does not cause color separation or odor, etc.
Based on these findings, we have completed the present invention. That is, the present invention provides titanium whose mica surface is coated with a lower titanium oxide, titanium oxynitride, or a titanium compound containing at least one of lower titanium oxide and titanium oxynitride, and whose surface is further coated with titanium dioxide. This cosmetic is characterized by containing mica coated with a compound. That is, the present invention uses titanium compound-coated mica and has adopted the following coloring mechanism not found in conventional pigments. First, a general mica coated with titanium dioxide is schematically illustrated as shown in FIG. In the figure, mica 10 is in the form of flakes, and the periphery of the mica 10 is coated with a thin layer of titanium dioxide 12. And, such titanium dioxide coated mica is
It has interference colors of various tones. This means that when titanium dioxide-coated mica receives white light 14 from the direction of arrow 1, part of the light is transmitted to the air-titanium 12 boundary and the titanium dioxide 1
2-Reflected at the mica 10 boundary. Each of the reflected lights 16, 18 has an optical path difference that depends on the layer thickness of titanium dioxide. As a result, interference light is generated as shown in FIG. In other words, the light component of the reflected light 16 with the wavelength as shown in FIG. , the peak of the light component of the reflected light 16 will be located at the valley of the light component of the reflected light 18, and the two will cancel each other out and disappear in appearance as shown in FIG. However, in the case of a light component with a wavelength half that of A, as shown in figure D, reflected light 16 and reflected light 18
Each light component is shifted by one wavelength, the peaks and valleys of both overlap, and amplitude amplification is performed as shown in FIG. Therefore, due to the interference effect, the light with the wavelengths shown in Figure 6A and B become visually invisible, while the light with the wavelengths shown in Figure 6D and E is intensified and is observed as interference light. be. In this way, by changing the optical path difference between the reflected lights 16 and 18, that is, the layer thickness of titanium dioxide, interference light of various colors such as gold, red, violet, blue, and green can be obtained. However, in the case of mere titanium dioxide-coated mica, most of the light 14 becomes transmitted light 20 because titanium dioxide and mica each have high light transmittance. This transmitted light 20 is generally said to have a complementary color relationship with the interference light;
0 is reflected by the skin 22, the reflected light 24 is neutralized by the interference light and the skin 22, resulting in a color close to white light. Therefore, although interference light can be observed depending on the viewing direction, the external color itself is always white. Therefore, the present inventors focused on this interference light and proceeded with further investigation, and found that by partially reducing the titanium dioxide in the titanium dioxide-coated mica, it was possible to reduce titanium dioxide or titanium oxynitride (hereinafter collectively referred to as low-order oxidation titanium oxide). By using titanium (referred to as titanium), they succeeded in emphasizing the inherent interference color of titanium dioxide-coated mica and obtaining an appearance color similar to the interference color. That is, as shown in FIG. 7, the surface of the titanium dioxide layer 12 is reduced to a lower titanium oxide layer 26. When the white light 14 is incident, the reflected lights 16 and 18 are almost the same as those shown in FIG. Considering that the light is reflected and passes through the titanium pigment again, the light passes through the dark low-order titanium oxide layer 26 four times. Therefore, the reflected light 24 on the skin 22
The influence of the reflected light 16 and the reflected light 18 is reduced, and the interference light between the reflected light 16 and the reflected light 18 is relatively emphasized. Thus, according to the cosmetic according to the present invention,
By covering the surface of white (translucent) titanium dioxide-coated mica with a black or dark-colored lower titanium oxide layer, it is possible to obtain bright interference colors and similar external colors. As a result, it has a color tone that is equal to or more vivid than conventional mica titanium pigments or colored mica titanium pigments with added color pigments, and has pearlescent stability, safety, light fastness, acid resistance, and A cosmetic containing a colored mica titanium pigment having excellent alkalinity, solvent resistance, and heat resistance can be obtained. Next, the configuration of the present invention will be described. The mica that is the raw material for the mica coated with the titanium compound that is blended into the cosmetics of the present invention may be of any type, and commercially available muscovite mica is generally used, but in some cases It is also possible to use biotite or the like. There is no particular restriction on the particle size, but when using it as a pigment in cosmetics, etc., mica with a small particle size and as flat a particle shape as possible among commercially available mica (particle size of about 1 to 50 μm) is preferable for beautiful colors and pearls. This is preferable because gloss is easily exhibited. The low-order titanium oxide used in the present invention refers to titanium whose degree of oxidation is lower than that of titanium dioxide (TiO 2 ), such as Ti 2 O, TiO, Ti 2 O 3 , Ti 3 O 5 ,
Examples include Ti 4 O 7 . The titanium oxynitride used in the present invention is a compound (Tix Ny Oz) in which nitrogen is solidly dissolved in generalized titanium (TiO), which is a low-order titanium oxide, and the compound varies depending on the amount of nitrogen solidly dissolved. In the present invention, those having values of x of 0.2 to 0.6, y of 0.05 to 0.60, and z of 0.1 to 0.9 are used. The mica coated with lower titanium oxide, titanium oxynitride, or a titanium compound containing at least one of lower titanium oxide and titanium oxynitride used in the present invention means that the surface of the mica is coated with the lower titanium oxide. or the surface of the mica is coated with at least one of the titanium oxynitrides, or contains at least one of the lower titanium oxides and the titanium oxynitrides as an essential component. In addition, it refers to a mica surface coated with a titanium compound mixture containing an arbitrary amount of a titanium compound such as titanium dioxide. Contains as an essential component lower titanium oxide or titanium oxynitride, or at least one of lower titanium oxide and titanium oxynitride, which is an intermediate for obtaining mica coated with the titanium compound blended in the present invention. In mica coated with a titanium compound (hereinafter referred to as intermediate), the content of lower titanium oxide or titanium oxynitride is preferably 0.01 to 60 parts by weight based on 100 parts of mica. The content of lower titanium oxide or titanium oxynitride is
If it is less than 0.01 parts by weight, the final mica coated with the titanium compound will have an interference color, but it will be difficult to obtain an appearance color that matches this, and if it exceeds 60 parts by weight, particles will tend to aggregate, which is not preferable. . Furthermore, in the above-mentioned intermediate, the total amount of titanium compound coated on the mica is preferably 200 Å or more in thickness, and further 900 Å in thickness when trying to obtain an excellent appearance color and interference color other than black. It is preferable that it is above. In the mica coated with a titanium compound incorporated in the cosmetic composition of the present invention, the amount of titanium dioxide in the outermost layer is preferably 50 Å to 5000 Å in layer thickness. If the layer thickness is less than 50 Å, good color cannot be obtained, and as the layer thickness increases, good color with an upper order interference color and an appearance color matching this can be obtained. It is enough as it is. Various methods can be used to produce mica coated with a titanium compound to be incorporated into the cosmetic composition of the present invention. First, to give an example of the method for producing the intermediate, commercially available titanium dioxide-coated mica is heated at a temperature of 500°C to 1000°C, preferably 700°C to 900°C, using one or two gases having reducing power such as hydrogen gas and ammonia gas. A method in which titanium dioxide is applied to commercially available titanium dioxide-coated mica using a method in which titanium dioxide is reduced by heating with a mixture of these gases having reducing power and an inert gas such as helium gas, argon gas, or nitrogen gas. A method of mixing the mixture and heating and reducing the mixture by the above method, or a method of mixing commercially available titanium dioxide-coated mica with metallic titanium and reducing the mixture under vacuum.
Examples include methods such as thermal reduction at 500°C to 1000°C, preferably 700°C to 900°C. Furthermore, an aqueous solution of an inorganic acid salt of titanium (e.g., titanyl sulfate) as seen in DuPont's patent (Japanese Patent Publication No. 43-25644) is hydrolyzed in the presence of the mica mentioned above to form hydrated titanium dioxide on the surface of the mica particles. is precipitated at 500℃~1000℃, preferably 700℃~
At a temperature of 900℃, one or more gases having reducing power such as hydrogen gas and ammonia gas, or combining these gases with reducing power and inert gas such as helium gas, argon gas, nitrogen gas, etc. The mixture may be heated and reduced with a mixed gas, or hydrated titanium dioxide may be precipitated on the surface of mica particles and then heated to produce mica titanium, which may be reduced in the same manner as the commercially available mica titanium pigments. . Further, the method of reduction is not limited to the method using a reducing gas such as hydrogen gas or ammonia gas as described above, but also a method of reducing titanium dioxide-coated mica using a reducing flame such as hydrogen, mica titanium salt, For example, it is also possible to suspend it in a titanium tetrachloride solution and oxidize and decompose this suspension in a flame of a mixed gas of air and hydrogen. Next, to exemplify the method of further coating the surface of the intermediate obtained as described above with titanium dioxide, the intermediate obtained as described above is heated and oxidized at a temperature of 140°C to 400°C in the air. In this method, an aqueous solution of an inorganic acid salt of titanium (for example, titanyl sulfate) is hydrolyzed in the presence of the above-mentioned intermediate to precipitate hydrated titanium dioxide on the surface of mica coated with a titanium compound, and then this is released into the atmosphere. method of heating,
Examples include a method in which titanium metal is mixed with the above intermediate and fired in the atmosphere, and a method in which these methods are used in combination. What is important about the mica coated with the titanium compound blended into the cosmetics of the present invention is that lower titanium oxide or titanium oxynitride is used as the intermediate layer between the innermost layer of mica and the outermost layer of titanium dioxide. The existence of a titanium compound layer that essentially contains . If this layer does not exist, excellent color tones such as brightness and chroma, which were originally intended, and good consistency between appearance color and interference color, etc., will not be achieved. When the intermediate layer is entirely composed of lower titanium oxide or titanium oxynitride, a black appearance color and black interference color can be obtained, and the intermediate layer also contains titanium dioxide in addition to lower titanium oxide or titanium oxynitride. In some cases, by further adjusting the amount of titanium dioxide coated thereon, it is possible to obtain materials having various external colors and interference colors such as silver, gold, red, blue, and green. The amount of mica coated with the titanium compound described above in the cosmetic according to the present invention can be any amount within the range of amounts generally used as powders and pigments, but is usually 0.5 to 80% by weight. Preferably 5
~60% by weight. If the amount of mica coated with a titanium compound is too large, moldability tends to deteriorate in the case of a solid powder product, and if the amount is too small, it is difficult to exhibit the effect as a colorant or pearlescent agent. The dosage forms of cosmetics containing mica coated with titanium compounds include emulsion, lotion, cream, ointment, stick, powder, dish, and multi-layered forms such as powder layer-water layer and oil layer. Any form that is commonly used as cosmetics may be used. In addition, it can be used for facial cosmetics, make-up cosmetics, hair cosmetics, body cosmetics, aromatic cosmetics, etc., but of course it can be used for foundation, cheek blush, whitening powder, eyebrows, eyelids, etc. Most suitable for make-up cosmetics such as lipstick and nail polish. In addition to the mica coated with the titanium compound described above, the cosmetics of the present invention contain higher aliphatic alcohols, higher fatty acids, ester oils, paraffin oils, oils such as wax, ethyl alcohol, propylene glycol, sorbitol, glycose, etc. Alcohols, mucopolysaccharides, collagens, PCA salts,
Moisturizing agents such as lactate, nonionic, cationic, anionic, various amphoteric surfactants, thickeners such as gum arabic, xanthan gum, polyvinylpyrrolidone, ethylcellulose, carboxymethylcellulose, carboxyvinyl polymer, modified or unmodified clay minerals, Solvents such as ethyl acetate, acetone, and toluene, inorganic and organic facial dyes, antioxidants such as BHT and tocopherol, water, drugs, ultraviolet absorbers,
Raw materials commonly used in cosmetics, such as PH buffering agents consisting of organic and inorganic acid salts, chelating agents, preservatives, and fragrances, are appropriately selected and blended. The cosmetic according to the present invention contains mica coated with a titanium compound that has a bright appearance color that matches the interference color, thereby creating a pearlescent cosmetic that matches the appearance color and the color when applied to the skin. be able to earn a fee. Excellent safety. Must have excellent stability over time without causing fading, discoloration, or odor. Excellent dispersion stability without causing color separation or color unevenness. It has the following effects. Next, the mica coated with a titanium compound to be incorporated into the cosmetic of the present invention will be explained by giving a manufacturing example. Production Example 1 50 g of mica was added to 500 g of ion-exchanged water and thoroughly stirred to be uniformly dispersed. 208.5 g of an aqueous titanyl sulfate solution having a concentration of 40% by weight was added to the obtained dispersion, and the mixture was heated and boiled for 6 hours while stirring. After cooling, it was washed with water and calcined at 900°C to obtain 80 g of mica coated with titanium dioxide (mica titanium). Next, the obtained titanium mica was subjected to a reduction treatment at 700° C. for 6 hours under an ammonia gas flow at a flow rate of 3/min, and after cooling, 78 g of powder was recovered. The obtained powder had a blue pearlescent appearance and interference color (Intermediate A). A photograph of the metallographic structure of the particle surface of this intermediate A (magnification
A scanning electron micrograph taken at 30,000x magnification is shown in Figure 1. According to this, it is possible to observe that the surface of each particle of intermediate A is sufficiently covered with fine particles. In addition, the X-ray diffraction diagram of this intermediate A (Cu-Kα
Figure 2 shows the diffraction angle (Bragg angle 2θ) in addition to the mica diffraction peak.
A peak is observed around 25.3°. This corresponds to 101, the strongest peak of anatase titanium dioxide. In addition, slightly broad peaks are observed near the Bragg angle 2θ of 43° and 37°, but these peaks are found from ASTM searches for titanium monoxide (TiO) in ASTM No. 8-117 and titanium nitride (TiO) in ASTM No. 6-0642. This is around the middle of the diffraction angle of TiN). To explain this crystallographically, titanium oxide and titanium nitride have the same cubic crystal system, but have different lattice constants and therefore different diffraction angles. That is, this means that the compounds contained in Intermediate A and whose X-ray diffraction angles 2θ are found around 43° and 37° are in the state of a solid solution of titanium oxide and titanium nitride. The general formula for solid solution is TixNyOz, which is titanium oxynitride. Determining the composition ratio from the intensity ratio of X-ray diffraction lines, Intermediate A is 60% by weight of mica, 227% by weight of titanium dioxide, and 17.3% by weight of titanium oxynitride.
The composition ratio was . Furthermore, in order to quantify the amount of oxygen and nitrogen, simultaneous quantitative analysis of oxygen and nitrogen was performed using a model TC-136 manufactured by LACO. As a result, oxygen was 41.7% by weight and nitrogen was 4.3% by weight. The results of the above-mentioned compositional analysis show that titanium oxynitride is Ti0.30N0.1900.51. As mentioned above, 50 g of Intermediate A, whose mica surface was found to be coated with titanium dioxide and titanium oxynitride, was further added to 500 g of ion-exchanged water and sufficiently stirred to uniformly disperse the mixture. Add 30% titanyl sulfate aqueous solution to the resulting dispersion with a concentration of 40% by weight.
g was added, and the mixture was heated while stirring and boiled for 6 hours. After cooling, rinse with water and dry at 200℃.
100 g of mica coated with a titanium compound to be incorporated into the cosmetic of the present invention was obtained. The resulting powder had a bright green exterior color and a matching interference color, and also had a pearl-like luster. The composition of this material was found to be 30.3% by weight mica and titanium dioxide based on the results of X-ray diffraction and LACO gas analysis.
The titanium oxynitride content was 61.0% by weight, and the titanium oxynitride content was 8.7% by weight.
Furthermore, Fig. 3 shows a photograph of the metallographic structure of the particle surface of this material (scanning electron micrograph at a magnification of 30,000 times).

After stirring the mixture well and spraying the perfume uniformly, the mica coated with the titanium compound obtained in Production Example 2 was uniformly mixed and compression molded to obtain a solid blush. Comparative Example 4 A blusher was obtained in the same manner as in Example 7, except that the product obtained in Production Example 2 in Example 7 was replaced with a conventional commercially available red-purple mica titanium pigment. 5 g of each of the blushes of Example 7 and Comparative Example 4 were placed in a 20 ml glass container with a stopper, and the containers were irradiated with a xenon lamp for 30 hours. Color difference before and after irradiation (△
E) was measured in the same manner as in Comparative Example 2.
The blush of Example 7 was stable with no discoloration with △E=0.1, whereas the blush of Comparative Example 4 was △ due to fading.
E=1.3 and discoloration was observed. Next, using the blushers of Example 7 and Comparative Example 4, we conducted a sensory evaluation of the difference in color between the appearance color and the applied color using a panel of 30 Japanese women aged 18 to 24 as a control, as shown in Table 2. For the blusher of Example 7, more than 90% of the panels recognized the match between the external color and the applied color, whereas for the blusher of Comparative Example 4, there was some color floating and the applied color was redder than the external color. 30% of panels said that
